On this page we will explain you how to change the Boot Logo/Screen of Linux.

By default the following screen is displayed on you LCD:

Default Boot.png

Create an image to suitable format (C include file)

  1. create a new image fitting the size of your LCD (320x240 or 480x272), with The Gimp for example
  2. save it in PNM RAW file format, let's say boot_logo.pnm
  3. install Netpbm package: 
    $ sudo apt-get install netpbm
  4. reduce number of colors in your image to 224: 
     $ ppmquant 224 boot_logo.pnm > boot_logo_224.pnm
  5. convert it to PNM ASCII format: 
     $ pnmnoraw boot_logo_224.pnm > boot_logo_ascii_224.pnm
  6. convert it to C include: 
    $ ./buildroot/build_arm/linux-2.6.23.1/scripts/pnmtologo -n armadeus_boot_logo -o ./buildroot/build_arm/linux-2.6.23.1/drivers/video/logo/logo_boot_armadeus_clut224.c -t clut224 boot_logo_ascii_224.pnm

Add your file to Linux build system

  1. Edit ./buildroot/build_arm/linux-2.6.23.1/drivers/video/logo/Makefile
  2. Add it your logo file name at line 16: 
     obj-$(CONFIG_LOGO_ARMADEUS_CLUT224)     += logo_boot_armadeus_clut224.o
  3. Edit ./buildroot/build_arm/linux-2.6.23.1/drivers/video/logo/logo.c
  4. Add it your logo C struct name at line 36: 
    extern const struct linux_logo armadeus_boot_logo;
  5. Add it your logo C struct name at line 110:
#ifdef CONFIG_LOGO_ARMADEUS_CLUT224 <br><br>        
    /* Armadeus Linux logo */
    logo = &armadeus_boot_logo;
#endif

Then recompile your kernel and install it on your board: 

$ make linux

Custom Boot Logo with login.png

Remove Login from framebuffer terminal

  1. On your target, edit /etc/inittab
  2. Comment line 28: 
    #tty1::respawn:/sbin/getty 38400 tty1
  3. save it and restart your system
