Hello Marco, thanks for your Tips - i searched since Monday for any hints !!! It seems that Atmel has done some work on u-boot but doesn't tell this their Customers ;-) Your "Howto replace u-boot..." is half the solution of my Problem. I have new Boards without any SW, the Flash is empty. So i want to Xmodem loader.bin and with this the u-boot and with this anything what does a boot out of Flash to u-boot :-)

Can you tell me, what to do to reach this ?

Thomas, if you have to program NOR parallel Flash you simply need to Remove the resistor R159 on the AT91RM9200-DK to start the processor from its internal boot ROM. Read the Datasheet

In any case for your (and other) reference I added some links here http://www.koansoftware.com/en/art.php?art=90

Ciao
