14.2.6. Net: No ethernet found

Question:

I have ported U-Boot to a custom board. It seems to boot OK, but it prints:

Net:   No ethernet found.

Why?

Answer:

Some network drivers (especially on ppc4xx) respond with such a message when no valid MAC address has been defined. Please make sure that a valid MAC address has been defined in the environment (using the "setenv" command). Then store the environment (using the "saveenv" command). After the next reboot, the Ethernet interface should be available.
