If you had waited for the second inteface to time out you would have
seen that U-Boot re-tried the first one which then should have worked.

It would not even have a first thought, as U-Boot never "exposes" any
IP addresses if you use appropriate protocols like DHCP or BOOTP. All
it "exposes" is it's MAC address.
