MartinH: /* Chipset Atheros AR9271 */

== About Zydas zd1211 tries ==
[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

Here is the part of "messages" where the error is :

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist after you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \
{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

Generic Driver Options --->
(/sbin/hotplug) path to uevent helper
[*] Maintain a devtmpfs filesystem to mount at /dev
[*] Automount devtmpfs at /dev, after the kernel mounted the rootfs

< > Hardware Monitoring support --->
[*] USB support --->
<*> Enable Wireless USB extensions (EXPERIMENTAL) </pre>

The Atheros driver needs some firmware to be installed. I got it from
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git
 You must download the entire reository and extract the ar9721.fw file locally.
<pre class="apf">
# ls -al /lib/firmware
total 52
drwxr-xr-x 2 root root 232 Jan 1 00:54 .
drwxr-xr-x 6 root root 2672 Dec 14 2012 ..
-rwxr-xr-x 1 root root 49280 Jan 1 1970 ar9271.fw
</pre>

 With this setup no modprobe is necessary. On Plugin of the Netgear WNA1100 the following should print:
<pre class="apf">
usb 2-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 2-1: Product: WNA1100
usb 2-1: Manufacturer: NETGEAR WNA

usb 2-1: ath9k_htc: Transferred FW: ar9271.fw, size: 49280
usb 2-1: ath9k_htc: USB layer initialized
</pre>
Let's assume you need to connect to share myshare on the SMB network drive to be mounted under /media/mydrive
 The following script /usr/bin/wlan_up will bring your WLAN up:
<pre class="host">
#!/bin/sh
until iwconfig | grep wlan0; do sleep 5; echo " tick "; done
ifconfig wlan0 up
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
ifconfig eth0 down
ifconfig wlan0 192.168.178.31
mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=
</pre>

The script starts up the WLAN wit WPA2 encryption. This requires the /etc/wpa_supplicant.conf file to be configured properly:
<pre class="host">
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="your SSID"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=TKIP
psk="your secret network password"
}
</pre>

The below script /etc/init.d/S99wlan will call the wlan_up script automatically at boot in case the wired LAN is not present:
<pre class="host">
#!/bin/sh
if mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=;
then
echo Using Wired LAN
else
echo Starting WLAN
/usr/bin/wlan_up &
fi
</pre>

The whole setup is not yet perfect -for example the IP address used by the scripts is hardcoded and of course must match the one that will be received from the dns server. Suggestions for improvement are welcome!

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist after you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

Let's assume you need to connect to share myshare on the SMB network drive to be mounted under /media/mydrive
 The following script /usr/bin/wlan_up will bring your WLAN up:

The whole setup is not yet perfect, for example the IP address used by the scripts is hardcoded and of course must match the one that will be received from the dns server. Suggestions for improvement are welcome!

MartinH: /* Chipset Atheros AR9271 */

== About Zydas zd1211 tries ==
[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

--[[User:Sly|Sly]] 20:33, 31 July 2012 (UTC)

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist after you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \
{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist after you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \
{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

The Atheros driver needs some firmware to be installed. I got it from
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git
 You must download the entire reository and extract the ar9721.fw file locally.
<pre class="apf">

-rwxr-xr-x 1 root root 49280 Jan 1 1970 ar9271.fw
</pre>

 With this setup no modprobe is necessary. On Plugin of the Netgear WNA1100 the following should print:
<pre class="apf">

Let's assume you need to connect to share myshare on the SMB network drive to be mounted under /media/mydrive
 The following script will bring your WLAN up:
<pre class="host">
#!/bin/sh
until iwconfig | grep wlan0; do sleep 5; echo " tick "; done
ifconfig wlan0 up
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
ifconfig eth0 down
ifconfig wlan0 192.168.178.31
mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=
</pre>

The script starts up the WLAN wit WPA2 encryption. This requires the /etc/wpa_supplicant.conf file to be configured properly:
<pre class="host">
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="your SSID"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=TKIP
psk="your secret network password"
}
</pre>

The below script /etc/init.d/S99wlan will call the wlan_up script automatically at boot in case the wired LAN is not present:
<pre class="host">
#!/bin/sh
if mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=;
then
echo Using Wired LAN
else
echo Starting WLAN
/usr/bin/wlan_up &
fi
</pre>

The whole setup is not yet perfect, for example the IP address used by the scripts is hardcoded and of course must match the one that will be received from the dns server. Suggestions for improvement are welcome!

MartinH: /* Chipset Atheros AR9271 */

== About Zydas zd1211 tries ==
[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist after you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

The Atheros driver needs some firmware to be installed. I got it from
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git
 You must download the entire reository and extract the ar9721.fw file locally.
<pre class="apf">
# ls -al /lib/firmware

-rwxr-xr-x 1 root root 49280 Jan 1 1970 ar9271.fw
</pre>

 With this setup no modprobe is necessary. On Plugin of the Nergear WNA1100 the following should print:
<pre class="apf">
usb 2-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48

usb 2-1: ath9k_htc: USB layer initialized
</pre>
Let's assume you need the LAN to connect to SMB network drive to be mounted under /media/mydrive
 The following script will bring your WLAN up:
<pre class="host">
#!/bin/sh
until iwconfig | grep wlan0; do sleep 5; echo " tick "; done
ifconfig wlan0 up
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
ifconfig eth0 down
ifconfig wlan0 192.168.178.31
mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=
</pre>

The script starts up the WLAN wit WPA2 encryption. This requires the /etc/wpa_supplicant.conf file to be configured properly:
<pre class="host">
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="your SSID"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=TKIP
psk="your secret network password"
}
</pre>

The below script /etc/init.d/S99wlan will call the wlan_up script automatically at boot in case the wired LAN is not present:
<pre class="host">
#!/bin/sh
if mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=;
then
echo Using Wired LAN
else
echo Starting WLAN
/usr/bin/wlan_up &
fi
</pre>

The whole setup is not yet perfect, for example the IP address used by the scripts is hardcoded and of course must match the one that will be received from the dns server. Suggestions for improvement are welcome!

MartinH: /* Chipset Atheros AR9271 */

== About Zydas zd1211 tries ==
[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

The below script /etc/init.d/S99wlan will call the wlan_up script automatically at boot in case the wired LAN is not present:
<pre class="host">
#!/bin/sh
if mount.cifs //192.168.178.28/myshare /media/mydrive/ -o user= -o pass=;
then
echo Using Wired LAN
else
echo Starting WLAN
/usr/bin/wlan_up &
fi
</pre>

The whole setup is not yet perfect, for example the IP address used by the scripts is hardcoded and of course must match the one that will be received from the dns server. Suggestions for improvement are welcome!

MartinH: /* Chipset Atheros AR9271 */

== About Zydas zd1211 tries ==
[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

< > Hardware Monitoring support --->
[*] USB support --->
<*> Enable Wireless USB extensions (EXPERIMENTAL) </pre>

The Atheros driver needs some firmware to be installed. I got it from
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git
 You must download the entire reository and extract the ar9721.fw file locally.
<pre class="apf">
# ls -al /lib/firmware
total 52
drwxr-xr-x 2 root root 232 Jan 1 00:54 .
drwxr-xr-x 6 root root 2672 Dec 14 2012 ..
-rwxr-xr-x 1 root root 49280 Jan 1 1970 ar9271.fw
</pre>

 With this setup no modprobe is necessary. On Plugin of the Nergear WNA1100 the following should print:
<pre class="apf">
usb 2-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 2-1: Product: WNA1100

usb 2-1: ath9k_htc: Transferred FW: ar9271.fw, size: 49280
usb 2-1: ath9k_htc: USB layer initialized
</pre>
Let's assume you need the LAN to connect to SMB network drive to be mounted under /media/mydrive
 The following script will bring your WLAN up:
<pre class="host">
#!/bin/sh
until iwconfig | grep wlan0; do sleep 5; echo " tick "; done
ifconfig wlan0 up
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
ifconfig eth0 down
ifconfig wlan0 192.168.178.31
mount.cifs //192.168.178.28/Media /media/mydrive/ -o user= -o pass=
</pre>

The script starts up the WLAN wit WPA2 encryption. This requires the /etc/wpa_supplicant.conf file to be configured properly:
<pre class="host">
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="your SSID"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=TKIP
psk="your secret network password"
}
</pre>

The below script /etc/init.d/S99wlan will call the wlan_up script automatically at boot in case the wired LAN is not present:
<pre class="host">
#!/bin/sh
if mount.cifs //192.168.178.28/Media /media/mydrive/ -o user= -o pass=;
then
echo Using Wired LAN
else
echo Startin WLAN

 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :

I use this trick for that :

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

The Atheros driver needs some firmware to be installed. I got it from
http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git
 You must download the entire reository and extract the ar9721.fw file locally.
<pre class="apf">

</pre>

 With this setup no modprobe is necessary. On Plugin of the Nergear WNA1100 the following should print:
<pre class="apf">

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:

ARCH := arm

KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->

</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">

wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace

</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

[[User:JulienB|JulienB]] 09:52, 4 February 2009 (UTC) : now working

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 ''buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c''
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
 The file will only exist until you change the ''linux-menuconfig'' as below and do the first make
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \

{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

After the fist compile change the file, do a ''linux-clean'' and ''make'' again.
 Rather than compiling the driver as a module, I compiled it directly into the kernel.
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">

== Chipset RTL8188CUS ==

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :
[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true]

Add those option in the makefile :
<pre class="host">
- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">
Device Drivers --->
[*] Network device support --->
[*] Wireless LAN --->
<M> USB ZD1201 based Wireless device support
</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :
<pre class="apf">
insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
wpa_supplicant -iwlan0 -c /etc/wpa_supplicant.conf -Dwext -B dhclient
udhcpc -i wlan0
</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">

you will have to use this command each time you boot your board.

endif
</pre>

And I need to rebuild the linux kernel with define WEXT_PRIV :
<pre class="host">
make linux-menuconfig
</pre>

I use this trick for that :
<pre class="config">

</pre>

Which give me :
<pre class="config">
│ Selects: WIRELESS_EXT [=y] && WEXT_PRIV [=n] && FW_LOADER [=y]
</pre>
Rebuild the kernel :
<pre class="host">
make linux-rebuild
</pre>
finally copy the driver to the target directory :
<pre class="host">
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/
</pre>

===Known issue===
Here is the test I made :

</pre>
Then I can ping wifi adress with 0% packet loss.

I connect with ssh it work ok for the few command I did.

'''Then I try to connect with SFTP from my PC (using FileZilla) :'''

'''the wifi goes down and the usb with it.'''

It should work now with the last git dev branch (5.1)
===old Workaround===
Here is the workaround to fix this issue:
Disable dynamic frequency scaling by setting the scaling_governor to "userspace" or "performance"
====1st solution: change governor at runtime====

<pre class="apf">
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
</pre>
you will have to use this command each time you boot your board.

====2nd solution: rebuild your kernel with default governor set to userspace or performance====
<pre class="host">
make linux-menuconfig
</pre>

<pre class="config">
CPU Power Management --->
Default CPUFreq governor (userspace) --->
( ) performance
( ) powersave
(X) userspace
( ) ondemand
( ) conservative
</pre>

build and update your APF kernel..

== Chipset Atheros AR9271 ==
The Netgear N150 WNA 1100 WLAN stick is based upon the Atheros AR9271 Chipset. The kernel 2.6.35.3 contains the driver for that chipset, but the specific USB ID for the Netgear stick is not listed in the source. Therefore I applied a little manual patch to the file
 buildroot/output/build/linux-2.6.35.3/drivers/net/wireless/ath/ath9k/hif_usb.c
 changing the current device ID against the ID 0x0846, 0x9030 of the Netgear device. (Maybe someone can add in here how to add instead how to change...)
<pre class="host">
#include "htc.h"

#define ATH9K_FW_USB_DEV(devid, fw) \
{ USB_DEVICE(0x0846, 0x9030), .driver_info = (unsigned long) fw }
// { USB_DEVICE(0x0cf3, devid), .driver_info = (unsigned long) fw }

static struct usb_device_id ath9k_hif_usb_ids[] = {
ATH9K_FW_USB_DEV(0x9271, "ar9271.fw"),
ATH9K_FW_USB_DEV(0x1006, "ar9271.fw"),
{ },
};

</pre>

Rather than compiling the driver as a module, I compiled it directly into the kernel.
 In make linux-menuconfig
 I added:
<pre class="config">
-*- Networking support --->

</pre>

More Details to follow soon......

I will give you the details for the RTL8188CUS driver for the APF28:
# the build procedure
# the error I got for AFP28 with AFP28dev
# and the workaround to fix it

===Build procedure===
I build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
You can get the driver here (chose RTL8188CUS) :

How-to use USB to Wi-Fi adapters on your APF boards.

==Prerequesities==
{{Note| You have to be sure that [[Wireless Tools]] are installed on your rootfs before going further.}}

* To use USB dongles with [[APF9328]], you'll need an [[APF9328DevFull]] development board, with USB Host configured. See [[ISP1761_Linux_driver|this page]] to know how to do that.

The RT2571WF Wi-Fi chipset can be found in the following devices:
* [http://www.ldlc.com/fiche/PB00023863.html D-Link DWL-G122] '''(not rev E1 !)'''
* D-Link WPA-110

Drivers are included in Linux kernel > 2.6.29, but firmware must be downloaded from serialmonkey website at [http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz this address].

===Kernel configuration===

* If not already done, Wireless network must be configured by selecting these options in ''make linux-menuconfig'':
<pre class="config">
[*] Networking support --->
Wireless --->
<*> Generic IEEE 802.11 Networking Stack (mac80211)
</pre>

* then, select the chipset :
<pre class="config">
Device Drivers --->
[*] Network device support --->
Wireless LAN --->
[*] Wireless LAN (IEEE 802.11)
<M> Ralink driver support
<M> Ralink rt2501/rt73 (USB) support
</pre>

===Wi-Fi configuration===

First mount the module:
<pre class=apf>
# modprobe rt73usb
</pre>

Then copy the firmware named ''rt73.bin'' (found in Module directory of
[http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz rt73-cvs] archive) in apf /lib/firmware directory. If /lib/firmware doesn't exist create it.

<pre class=apf>
mkdir -p /lib/firmware
tftp -g -r rt73.bin <yourIP>
mv rt73.bin /lib/firmware
</pre>

Your Wi-Fi module driver is ready, you can now connect the dongle and after go further with the [[WiFi|Wi-Fi configuration]].

==Ralink RT2870==
* Activate the driver in Linux configuration (if not already done):
<pre class=host>
$ make linux-menuconfig
</pre>
* Load driver
<pre class=apf>
# modprobe rt2800_usb
</pre>
* Be sure to have rt2870.bin in /lib/firmware

==ZyDas zd1212 chipset==
* Tested with SMC WUSB-G (which is in [http://www.linuxwireless.org/en/users/Drivers/zd1211rw/devices the compatibility list]).

USB to WiFi adapter

2012-12-23T19:29:32Z

MartinH: /* Tested hardware */

How-to use USB to Wi-Fi adapters on your APF boards.

==Prerequesities==
{{Note| You have to be sure that [[Wireless Tools]] are installed on your rootfs before going further.}}

* To use USB dongles with [[APF9328]], you'll need an [[APF9328DevFull]] development board, with USB Host configured. See [[ISP1761_Linux_driver|this page]] to know how to do that.

==Ralink RT2571WF==
The RT2571WF Wi-Fi chipset can be found in the following devices:
* [http://www.ldlc.com/fiche/PB00023863.html D-Link DWL-G122] '''(not rev E1 !)'''
* D-Link WPA-110

Drivers are included in Linux kernel > 2.6.29, but firmware must be downloaded from serialmonkey website at [http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz this address].

===Kernel configuration===

* If not already done, Wireless network must be configured by selecting these options in ''make linux-menuconfig'':
<pre class="config">
[*] Networking support --->
Wireless --->
<*> Generic IEEE 802.11 Networking Stack (mac80211)
</pre>

* then, select the chipset :
<pre class="config">

[*] Network device support --->
Wireless LAN --->
[*] Wireless LAN (IEEE 802.11)
<M> Ralink driver support
<M> Ralink rt2501/rt73 (USB) support
</pre>

===Wi-Fi configuration===

First mount the module:
<pre class=apf>
# modprobe rt73usb
</pre>

Then copy the firmware named ''rt73.bin'' (found in Module directory of
[http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz rt73-cvs] archive) in apf /lib/firmware directory. If /lib/firmware doesn't exist create it.

<pre class=apf>
mkdir -p /lib/firmware
tftp -g -r rt73.bin <yourIP>
mv rt73.bin /lib/firmware
</pre>

Your Wi-Fi module driver is ready, you can now connect the dongle and after go further with the [[WiFi|Wi-Fi configuration]].

==Ralink RT2870==
* Activate the driver in Linux configuration (if not already done):
<pre class=host>
$ make linux-menuconfig
</pre>
* Load driver
<pre class=apf>
# modprobe rt2800_usb
</pre>
* Be sure to have rt2870.bin in /lib/firmware

==ZyDas zd1212 chipset==
* Tested with SMC WUSB-G (which is in [http://www.linuxwireless.org/en/users/Drivers/zd1211rw/devices the compatibility list]).

MartinH:

Hi there,

As an electrical engineer working on the development of automotive micro controllers (well, too small to run Linux) I decided to
widen my view also on ARM and embedded Linux.

My project is an '''Audio Streaming Client,''' based on the MPD so the APF28 with it's SPDIF out is a perfect choice.

With zero experience in embedded Linux, I got my "Hello World" out of my stereo speaker a week after I received my APF28_dev.

Meanwhile the whole MPD is up and running over ETH cable. Now I am fighting to get my Netgear WNA1100 WLAN stick to work.
(OK, I could spend 10 Euro on a supported one, but I try to be a good sports)

UPDATE:
SUCCESS!! I got the Netgear N150 WNA1100 stick up and running.
The version 1.0 of my streaming client is fully working with it.

My mother language is German, but I can also read French (ecrire est un petit plus difficile).
If you have any questions, suggestions or ideas how to upgrade the APF28 kernel , please feel free to contact me

MartinH: /* Network configuration */

On this page you will learn how to flash new U-Boot, Linux and rootfs images on your APF module.

==Configure U-Boot==

===Environment variables===
U-Boot can be customized in a flexible way with the use of "environment variables/scripts".
The command '''printenv''' shows you most of them and their current value:
<pre class="apf">
BIOS> printenv
bootcmd=run jffsboot
bootdelay=20
baudrate=115200
ethaddr=
autoload=no
...
</pre>
The command '''setenv''' is used to change these variables. For example, to set the IP address (don't do it yet):
<pre class="apf">
BIOS> setenv ipaddr 192.168.0.10
</pre>
The command '''saveenv''' is used to save the state of your environment variables in FLASH memory; that way they will be available at next boot:
<pre class="apf">
BIOS> saveenv
Saving Environment to Flash...
. done
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash... done
. done
Protected 1 sectors
</pre>

===Network configuration===
In order to use the U-Boot's network features, you have to set the network environment variables:
<pre class="apf">
BIOS> setenv netmask 255.255.255.0 (this default value should be fine in most situations)
BIOS> setenv ipaddr 192.168.0.10
BIOS> setenv serverip 192.168.0.2 (the IP address of your tftp server/PC hosting the files to download)
BIOS> setenv rootpath "/tftpboot/apf9328-root" (to boot Linux over NFS)
</pre>
You can use the '''dhcp''' command to configure these variables from your DHCP server. You probably will have to adjust the '''serverip''' variable manually.
If you use VirtualBox make sure you have selected Bridge Mode for the network adaptor, otherwise the UBOOT cannot talk to your host.
<pre class="apf">
BIOS> dhcp
dm9000 i/o: 0x15c00000, id: 0x90000a46
MAC: 00:0e:32:00:00:01
operating at 100M full duplex mode
BOOTP broadcast 1
DHCP client bound to address 192.168.0.10
BIOS> setenv serverip 192.168.0.2
BIOS> saveenv
</pre>
Do not forget to save your changes in FLASH, to have them available at next power up:
<pre class="apf">
BIOS> saveenv
</pre>
In case of troubles you can use the following U-Boot script to reset the variables to the "factory"/default settings:
<pre class="apf">
BIOS> run flash_reset_env
</pre>

==Linux kernel installation==
XX, in the following chapters, has to be replaced by your board name

* Check that your Armadeus kernel image size is smaller than the U-Boot partition (see [[#Flash_memory_partitions|Flash Memory Partitions]] for size allowances):
<pre class="host">
[armadeus]$ ls -al buildroot/output/images/
</pre>
* If yes, copy it to your TFTP server directory (here ''/tftpboot/''):
<pre class="host">
[armadeus]$ cp buildroot/output/images/* /tftpboot/
</pre>
===Linux kernel update script===
* This is the recommended method and the easiest one. The automatic 'update_kernel' scripts downloads the image and flash it in the same go:
<pre class="apf">
BIOS> run update_kernel
</pre>
* To know what ''update_kernel'' script is doing you can display its content:
<pre class="apf">
BIOS> printenv update_kernel
</pre>
{{Warning|If the loaded kernel image is too large, the following operation can destroy data that are stored after the partition limits (e.g. RootFS) - Check that transfered size value is less than the ones specified here [[#Flash_memory_partitions|Flash Memory Partitions]]
}}

===Other Linux kernel update method===
* Load kernel image with U-Boot through network:
<pre class="apf">
BIOS> run download_kernel
</pre>
or with the serial line:
<pre class="apf">
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then:''
(/home/.../) C-Kermit>send /tftpboot/XX-linux.bin
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of XX-linux.bin> = .... Bytes
## Start Addr = 0x08000000
BIOS> setenv filesize <size of XX-linux.bin>
</pre>

----
Check that transfered size value is less than the ones specified here [[#Flash_memory_partitions|Flash Memory Partitions]]
<pre class="apf">
Bytes transferred = 1313216 (1409c0 hex)
</pre>
----

* You can test your new kernel image without flashing it with; if so you will have to reload it again after test:
** '''Please note''': The ''bootm'' command is not supported by [[APF51]] boards yet; directly flash the kernel with the below commands instead
<pre class="apf">
BIOS> bootm
</pre>
* a U-Boot script exists to ease kernel image loading through Ethernet:
<pre class="apf">
BIOS> run download_kernel
</pre>
* After kernel image has been downloaded into RAM memory, you can flash it with:
<pre class="apf">
BIOS> run flash_kernel
</pre>
* If you only want to try a new kernel without flashing the kernel image you can launch it directly from RAM (U-Boot 2011.12):
<pre class="apf">
BIOS> setenv bootargs console=${consoledev},${baudrate} ${mtdparts};run addubifsargs addipargs; bootm
(the kernel image you want to try must have been loaded at ${loadaddr})
</pre>
* '''Please note''': The ''bootm'' command is not supported by [[APF51]] boards yet; directly flash the kernel with the below commands

==rootfs installation==

* Check that your Armadeus rootfs image size is smaller than the rootfs partition (see [[#Flash_memory_partitions|Flash Memory Partitions]] for size allowances):
<pre class="host">
[armadeus]$ ls -al buildroot/output/images/
...
[armadeus]$ cp buildroot/output/images/* /tftpboot/
</pre>
* Load rootfs image with U-Boot through network:
<pre class="apf">
BIOS> run update_rootfs
</pre>
For large rootfs (bigger than the available RAM on your system) please use this method ('''not''' supported on the [[APF9328]]):
<pre class="apf">
BIOS> nand erase.part rootfs
BIOS> tftpboot ${rootfs_addr} ${board_name}-rootfs.ubi nand
</pre>

or serial line:
<pre class="apf">
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then...''
(/home/.../) C-Kermit>send path_to_your_host_buildroot_dir/XX-rootfs.ubi
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of rootfs>
## Start Addr = 0x........
BIOS> setenv filesize <size of rootfs>
BIOS> run flash_rootfs
</pre>

* Now you should be ready to test Linux:
<pre class="apf">
BIOS> boot
</pre>

==FPGA firmware test==

The FPGA firmwares are all located in the ''firmware/'' directory of your Armadeus view:
[armadeus]$ ls firmware/
apf_pkg BRAMTest bus_led led PS2 PS2_Opencore servo sram_test wishbone_example Xtools
You can make some trials with the ''firmware/PS2/ps2_top.bin'' file. 
 

{{Warning| for the APF9328, Check that your bitfile size is smaller than the firmware partition size (256KB) before trying the following commands or you may corrupt your Linux kernel FLASH partition !!!}}
{{Note | For the APF51 only binary file format work ('''.bin'''). Do not use '''.bit''' format}}

* Load FPGA firmware image file with U-Boot through: 
Ethernet:
<pre class="apf">
BIOS> tftpboot ${loadaddr} fpgafirmware.bin
</pre>
''fpgafirmware.bin'' is of course the name of your bitfile stored in your TFTP shared directory (''/tftpboot/'')

then you can type the c command to reconnect to the terminal

* Test your new FPGA firmware's downloading:
<pre class="apf">
BIOS> fpga load 0 ${loadaddr} ${filesize}
</pre>

==FPGA firmware installation==

* Flash your firmware image with:
<pre class="apf">
BIOS> run flash_firmware
</pre>
* When you are '''satisfied with your firmware''', you can make it "autoloaded" at power up:
<pre class="apf">
BIOS> setenv firmware_autoload 1
BIOS> saveenv
</pre>
{{Note | (U-Boot 2011.12) you can manually cancel the firmware autoload using the following procedure: keeping <CTRL-C> pressed on the console and power up the board will start the board without downloading the FPGA firmware - This procedure can be helpfull if you have programmed a broken firmware }}

==Update U-Boot==
* Check that your Armadeus U-Boot image size is smaller than the u-boot partition (see [[#Flash_memory_partitions|Flash Memory Partitions]] for size allowances) and copy all the binary images to your TFTP server directory:
<pre class="host">
[armadeus]$ ls -al buildroot/output/images/
...
[armadeus]$ cp buildroot/output/images/* /tftpboot/
</pre>

===U-Boot update script===
* This is the recommended method and the easiest one. The automatic 'update_uboot' scripts downloads the image and flash it in the same go:
<pre class="apf">
BIOS> run update_uboot
</pre>

* Reset your board and check if you need to update your environment variables:
<pre class="apf">
BIOS> reset
U-Boot 2011.12 ..
...
*** Warning - Environment version change suggests: run flash_reset_env; reset
BIOS> run flash_reset_env; reset
</pre>
In such a case you may have to update your network environment variables (see [[#Configure_U-Boot|Configure U-Boot]])
===Other U-Boot update method===
You can use the following commands to download U-boot in RAM: 
*With Ethernet and a TFTP server:
<pre class="apf">
BIOS> run download_uboot
</pre>
*With Ethernet and a NFS server:
<pre class="apf">
BIOS> nfs ${loadaddr} host_ip_addr:/nfs_path_to_buildroot/apfXX-u-boot{.bin|-nand.bin|.sb}
</pre>
*With kermit and the serial/RS232 line
<pre class="apf">
BIOS> loadb ${loadaddr}
<CTRL><ALT GR>\
c
send path_to_buildroot/apfXX-u-boot{.bin|-nand.bin|.sb}
c<ENTER>
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of U-Boot> = .... Bytes
## Start Addr = 0x08000000
BIOS> setenv filesize <size of U-Boot>
</pre>

Then you can use the U-Boot command/script 'flash_uboot' to tranfert the new U-Boot from RAM to Flash memory:
<pre class="apf">
BIOS> run flash_uboot
</pre>

Advanced informations can be found at the [[BootLoader]] wiki page.

==Update U-Boot, kernel and rootfs images all at once==
* Copy all the binary images to your TFTP server directory:
<pre class="host">
[armadeus]$ cp buildroot/output/images/* /tftpboot/
</pre>

* The automatic 'update_all' scripts downloads each image and flash it in the same go:
<pre class="apf">
BIOS> run update_all
</pre>

* Reset your board to check that wour board is correctly updated.

{{Note |When updating your board from a legacy version of Armadeus BSP you should update U-Boot first to update the environment variables before any other partition update ( see [[#Update_U-Boot|Update U-Boot]]) }}

Hi there,

As an electrical engineer working on the development of automotive micro controllers (well, too small to run Linux) I decided to
widen my view also on ARM and embedded Linux.

My project is an '''Audio Streaming Client,''' based on the MPD so the APF28 with it's SPDIF out is a perfect choice.

With zero experience in embedded Linux, I got my "Hello World" out of my stereo speaker a week after I received my APF28_dev.

Meanwhile the whole MPD is up and running over ETH cable. Now I am fighting to get my Netgear WNA1100 WLAN stick to work.
(OK, I could spend 10 Euro on a supported one, but I try to be a good sports)

Wish I had a linux kernel above 2.6.3 running! The next one has the WNA1100 driver contained in the kernel
- with the current one I am just gathering experience with patching ;-)

Up to now I could not manage to get the 3.6.2 Vanilla kernel to boot as described on the wiki page.

My mother language is German, but I can also read French (ecrire est un petit plus difficile).
If you have any questions, suggestions or ideas how to upgrade the APF28 kernel , please feel free to contact me
