Dear All

Das U-Boot uses NOR FLASH for saving environment values 
for example IPADDR,GATEWAY and so on.
I have a board with only NAND FLASH (SAMSUNG NAND FLASH 64M) without
NOR FLASH and when I entered saveenv command to save environment values
to NAND FLASH in U-Boot
Some message returned and my values are not saved into NAND
======= Message ================
SMDK2410 # saveenv
Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash...Erasing sector 18 ... ok.
Erased 1 sectors
Writing to Flash... Flash not Erased
Protected 1 sectors
===== End of Message ===========

How Can I save environment values to NAND FLASH?

Best regards
