Hi, all!
I'm trying to implement splash screen on OMAP35xx-based device with 128x128 1bpp display connected using RFBI, plain parallel interface. Display has controller and own memory, and is controlled with parallel interface, 8-bit wide data bus and signals.
This display works under Linux, but I can't implement that using u-boot, display just doesn't power on, while I see that data is on bus with oscilloscope. Linux version works using interrupts, so I can't do this with u-boot, and that'd be simply overkill using this in u-boot. I think I miss something simple.
Have anybody implemented such a thing, I just need to make it into dumb parallel mode, just to display simple image. Any examples, ideas?
Most probably it won't help you, as it seems you have some HW configuration issues. But for OMAP3 splash screen example see
