Can you help me ?

According to the documents I found, you should be loading at 21000000, not 20200000:
>tftp 21000000 linux-ek

The AT91 website was just updated with new info for the EK board. Look here:

Also, did you update UBOOT to 1.1.1???

hello,

thanks for your reply, i'll go to visit the web site
I haven't update uBoot to 1.1.1 my current version is Uboot1.1.0
What is the difference between the two versions?

excuse for the mystakes, I'm a french student

after the bootm command, i see :
Starting kernel ...
but nothing else
I haven't a USB keyboard, could you tell me if it's the problem ?

thanks,
greg

I don't know anything about 1.1.0, but I know that the 0.3.0(?) version that was pre-installed on my board would not write to the flash.

I was able to boot up without a keyboard installed on the dev board.

Make sure all the environment setting are correct, expecially "bootargs". First time I tried I had initrd=0x21100000,60000000 when it should have have been 6000000 (one less zero). Follow the instructions at the link I posted above exactly. That worked for me.

The problem was the version 1.1.0-pre0 of u-boot. I upgrade u-boot to 1.1.1 and the kernel boot but i see on the screen of the board and no on the RS232
Thank for alll
