[U-Boot] Howto u-boot an evk1100 ?

[Sril]

Hi,
I plan to run linux on this box : sdramc bug free on my atevk1100.
I took patches from mailling list archive but, when I compile I can see led 4 red unblanking and led 5 green unblanking.
Does someone knows what does this mean ?
I try to put usart0 but nothing on minicom : usart1 successfully tested on usart_example.c from atmel dev kit for evk1100.


What must I do : where are docs, please ?

Best regards.
