Why are you doing this? If you have U-Boot running, you can just use the existing old version to download and install the new image. This is a trivial procedure.

Wolfgang, thank you for answering. I have done as you suggested, but now the board don't boot (I am going to install the old u-boot) I don't understand why the default configuration for at91rm9200dk is don't work on my board, after 3 days I'm still unable to use 1.1.3 :-( BTW the u-boot.gz I am sending here is created with gzip-ping u-boot.bin

These are the commands I've done:

Uboot> loadb 20000000 ...SEND BOOT.BIN... ## Ready for binary (kermit) download to 0x20000000 at 115200 bps... ## Total Size = 0x00002908 = 10504 Bytes ## Start Addr = 0x20000000 Uboot> cp.b 20000000 10000000 5fff Copy to Flash... done

Uboot> protect on 10000000 10005fff Protected 3 sectors

Uboot> loadb 20000000 ...SEND U-BOOT.GZ... ## Ready for binary (kermit) download to 0x20000000 at 115200 bps... ## Total Size = 0x0000b9a9 = 47529 Bytes ## Start Addr = 0x20000000

Uboot> protect off 10010000 1001ffff Un-Protected 1 sectors

Uboot> erase 10010000 1001ffff Erase Flash from 0x10010000 to 0x1001ffff Erasing sector 8 ... ok. Erased 1 sectors

Uboot> cp.b 20000000 10010000 ffff Copy to Flash... done

Uboot> protect on 10010000 1001ffff Protected 1 sectors Uboot>

...here resetting...

boot 1.0 (Aug 8 2003 - 12:29:00) Uncompressing image...
