Wolfgang,
thanx for your answer.
It turned my into a tiny worm, but that is the game ;-)
I must say that i am not very familiar with embedded dev (you've seen it i
guess ;-) )
Effectively, i have missed the FAQ, i surrender. I have spent a lot of time
in this problem and there's a lot of source of documentation on the web
(AT91, mailing lists, ...) that i missed the most obvious.

No.

Yes, it is the start of RAM banks. U-boot is loaded at 21F000000 (i don t
now exactly why it is not loaded at 20000000)

i have done it but u-boot makefile are very generic, it is difficlt to read
them for a rookie like me ;-)

Thanx again for the time you spend (or waste) to help me.
