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.

Hi,
No, you must erase the flash region where the MAC address is stored.

u-boot has "eeprom" command ? But I cannot find it! as I got MAC addresses don't match. Can u-boot allow me to change HW MAC address?
Best regards.

How can I use the correct MAC address?
I have read the FAQ, so maybe there are some problems on linux kernel side. http://www.denx.de/wiki/view/DULG/EthernetDoesNotWorkInLinux I also reference to http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2004-July/023579.

But I still have no idea how to deal with it. Could someone help me please?
