Hi,
I have compiled Uboot version u-boot-2010.06-rc3 and I got bin file .
I tried it to download bin file to at91rm9200dk board it stops after some time witth error .
How did you try to load the file to your device?

I think this is due to insufficient of SRAM capability ie 16KB SRAM uboot size is 107KB
I think you have chosen the BOOTROM based upload via xmodem cause you talk about SRAM size which does not matter if you boot from NOR flash on CS0.

You will need a bootstrap loader for this ... U-Boot will not fit in SRAM!

Ouch ok, I could have seen this in older messages.
I did not manage booting from serial dataflash for AT91SAM9263 by only using U-Boot (someone could give another advice if this is not correct). I used a bootstrap loader called at91bootstrap. Unfortunately there are only AT91SAM devices supported.
I also did some at91rm9200 bootstrap hacking for xmodem upload years ago. Will search for this software this evening and contact you off list since this is not U-boot related.
