2009-09-23 06:47:46     splash screen on custom board (bf537) with custom display (vga)

Hi,

 

I can't seem to find any good documentation on how to customize u-boot to show a splash screen on our board.

 

Somehow I need to tell uboot what resolution our display is, what timings it shound use and so on, but I can't seem to find out where.

 

I've tried to load the defauld bf548 u-boot - because it shows a splash screen (modified for our board), but no luck, nothing shows up.

 

It can't be eneough just to enable CONFIG_SPLASH_SCREEN, I need to define some other options, right?!

 

 

 

If somebody could point me in the right direction, I would really appreciate it.

You need to modify the LCD driver (which is in ./boards/xxx/video.c)

Thanks,

 

Updating to u-boot 2009 helped.

 

 

 

Note for others: I think this file (or custom video support) was introduced in 2008R1.5, so be sure to use u-boot no older then 2008R1.5!
