    Where did you get the U-boot sources that you based your work off of. U-boot version and SDK version that you based this modifications off of would be helpful especially so we can track deltas to see what changes you have made.

    Also I am not sure why your trying to use U-boot to display a picture. Configuration of any kind of display is best kept to the kernel since U-boot isn't meant to be used to display a picture. Can you explain your purpose in doing so? It even looks like the patch your basing your work off of (0041-beaglebone-add-ssd1289-support.patch) is a kernel patch.
