Subject: [U-Boot] OMAP3, RFBI, splash screen
Date: Fri, 18 Sep 2009 17:54:02 +0400	[thread overview]

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?

All the best,
S.
