[U-Boot-Users] Changing ethaddr

[Javier Gracia]

Hello, I am working with the Atmel board AT91RM9200-EK and I would
like to change the MAC address from U-boot. If I do: setenv ethaddr
(new_mac), I obtain: Can't overwrite "ethaddr". I am using a version
of U-boot from Atmel (u-boot-1.1.5_atmel_1.2). How can I change this
hw address?

Thanks,
Javier
