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>
