Do you guys have the code somewhere for others to test? Marc, do you mean keyboard support for UBoot is not even attempted? Serial console is not readily available on the AC100 :) > You indeed need to load fastboot first which initialized the LCD.

The one I think is most user friendly is having it flashed to part 6 and booted by fastboot. I do not know very well how the onboard bootloader works, this is what I understand so far: There's a fastboot instance in the EBT partition(?) (which behaves differently in Android 2.1 and 2.2) that checks part 6 (and 5) for a valid abootimg then loads it. UBoot could be put in such an abootimg and optionally offer interactive booting. UBoot could also be run in another mode for development, out of RAM, but I am not sure how that would involve nvflash and fastboot. Download fastboot as we do now for reading/writing partitions but then sending it commands to load another image in RAM and start it? Jani
