Too bad. This difference in boards makes the tests a bit less
meaningful. Is there really no USB-ethernet adapter somewhere in your
department (perhaps a non-SMSC95xx might serve as well?)? I might
send/order you one if necessary. ;)

Why is this? What does happen? Does U-Boot not boot up to the prompt?
Please send me a log.

Done, please see below.

I don't have a beagle-xm, only my beable. And my U-Boot network setup is
already working, thanks.

I added "ignore_loglevel" to the cmdline. But I cannot see anything
interesting that has not been there before with "debug" as well.

Okay, I tested again with U-Boot v2013.01 plus my SMSC patch. Same
problem. NFS booting/mounting hangs at some time.

Thanks,
