| == Introduction ==
| |
|
| |
|
| On APF6_SP it's possible to use the PCI express bus to configure fpga (cycloneV). This article describe how to do that.
| |
|
| |
| == Generate files ==
| |
|
| |
| === Quartus configuration ===
| |
|
| |
| Your design must include the PCIe and CvP components. Once the project synthesized, open the menu
| |
| <pre class="config">
| |
| File -> Convert Programming Files ...
| |
| </pre>
| |
|
| |
| * In '''Output programming file''' select the '''programming file type:''' Raw Binary File (.rbf).
| |
| * In '''Input files to convert''' clic on '''Add Files...''' and add your binary.sof file.
| |
| * In '''Output programming file''' check the option Create CvP files (Generate binary.periph.rbf and binary.core.rbf)
| |
| * Click on '''Generate'''
| |
|
| |
| You will get two files :
| |
|
| |
| * '''binary.periph.rbf''': peripheral config file to be loaded via serial config bus with uboot
| |
| * '''binary.core.rbf''': core config file to be loaded via PCIe bus with Linux.

| === Linux configuration ===
| |
|
| |
| == Configure the FPGA ==
| |
|
| |
| === Peripheral configuration in uboot ===
| |
|
| |
| PCIe must be activated before Linux boot. To do that, just load the peripheral bitstream with uboot :
| |
|
| |
| <pre class="apf">
| |
| BIOS> tftpboot ${loadaddr} 192.168.0.117:binary.periph.rbf
| |
| BIOS> fpga load 0 ${loadaddr} ${filesize}
| |
| </pre>
| |
|
| |
| Then boot Linux:
| |
| <pre class="apf">
| |
| BIOS> boot
| |
| </pre>
| |
|
| |
| === Core configuration in Linux ===
| |
|
| |
| The PCIe device must be seen in lspci command in Linux :
| |
| <pre class="apf">
| |
| # lspci
| |
| 00:00.0 PCI bridge: Device 16c3:abcd (rev 01)
| |
| 01:00.0 Unclassified device [0013]: Altera Corporation Device e001 (rev 01)
| |
| </pre>
