[U-Boot-Users] eth0: Invalid ethernet MAC address

[kabbin]

Dear Daniel
   When I use "NFS" command in u-boot, I got:

Warning: MAC addresses don't match:
HW MAC address:  00:00:00:00:00:00
"ethaddr" value: 00:50:C2:42:B2:62

How can I find the right flash region where the MAC address is stored ? (and then modify the data)
Do I need rebuild u-boot or linux kerenl?

Best regards.
