[U-Boot-Users] u-boot on AT91RM9200-EK

[Martin Zemlicka]

Hello Remy.

Thank you a lot for your help and useful informations besides.
Finally I successfully compiled and run u-boot 1.2.0 after some changes of source code and utilizing my
lowlevel software as loader instead the original loader. If you would be possibly interested in, I can send 
you what I have.
Thank you once more.

Regards Martin

# ----------------------------------------
# I have already succeeded with u-boot-1.2.0 for at91rm9200ek.
# Thank you all for your advices.
# 
# Maybe I should make a patch but I think that my way isn't correct.
# 1. I used another cross compiler than default.
# 2. I had to change something with usb in source codes ( maybe it won't function
# correctly, I haven't still experiences with usb on arm )
# 3. I had to disable using irq ( used for MCI )
# 4. I had to use my own lowlevel loader instead loader from atmel
# 
# Regards Martin
