Re: [U-Boot-Users] U-boot and ethernet on a Lubbock board

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.
