ARM STN
Hi All,
If anyone can offer some assistance please do. I'm working on a Color STN for an ARM board. My timing looks good but I'm unable to to get the penguin on the screen. Except for a very brief "glip" on the screen, nothing is shown. The address of the frame buffer and the UBASE are the same but I'm not sure why I'm not getting any screen output. console = tty does not produce anything. Could anyone spot anything unusual in the log below? Any other suggestions are welcome.
Thanks,
