I've been working last months on a lubbock board and u-boot as a bootloader to run Linux. I always loaded my kernel via serial port, because I never got u-boot to activate my ethernet (I never got the link led on, only after booting Linux).
I recently read the FAQ again and found about using valid MAC addresses:
- Should I recompile my u-boot with the new local-admin MAC address or just I need to write the new config on the board?
To change the MAC addresses, only the environment needs to change as follows ...
u-boot> setenv ethaddr <valid MAC address> (eth0) u-boot> setenv eth1addr <valid MAC address1> (eth1) u-boot> setenv eth2addr <valid MAC address2> (eth2) u-boot> saveenv
Omit references to eth1 or eth2, if they don't exist on your specific board.
There is no need to recompile U-Boot.

Thanks, did it. There's something I must been doing wrong, because I can't manage to get it work. The "link" led never turns on until I boot Linux. Then everythings works as it should. But uploading data to the board through a serial link is *slow*.
