Hi,
I ran up a banana PI and noticed that HDMI works in U-Boot. Great!
Scrolling seems very slow though - is the L2 cache disabled perhaps?
I don't think so, but it could be, I think the scrolling code is just very inefficient. Feel free to poke things a bit around this, ARM cache management is not my forte.
Also are there instructions for getting an LCD running in U-Boot? I have an Olimex A20-OLinuxion-MICRO (what a mouthful!) with a 7 inch display if that matters. I can't find any useful information so far.
He he, your in luck I've been working on LCD support the last few days, and I just got the olimex 7" lcd running on olimex boards :)
If you use my current wip tree:
https://github.com/jwrdegoede/u-boot-sunxi/tree/sunxi-wip
And build for the A20-OLinuXino_MICRO-lcd7_defconfig things should just work, assuming you are using the standard olimex 7" lcd with a standard 40 pins pata cable.
Note in order for the kernel to take over the fb you need a small kernel patch on top of 3.19, I've attached the patch.
