It is very bad style to post just snippets of the output.  Please
alwaus make sure to include the complete outout _and_ the command you
were running.

Above, you are talking about NFS, but what you show here are looks
more like a TFTP download than NFS access.  But you did not allow to
see us what you actually did, so we can only guess.   That's a bad
starting point for us...

Note that TFTP and NFS are totally different things.

OK, so your network transfers are failing at a low level.
Unfortunately you did not include enough output to see which
interface was used here, so I can only guess that it might have
been eTSEC1 ?

Do you have a (working, i. e. tested!) network cable attached to
eTSEC1? Does it report a link? [Again, this is vital information you
failed to provide!!]

Do you have a MAC address set for this interface?  Is it a valid MAC
address?

You throw just snippets of some random output at us, that are from
commands that are totally unrelated from what you say you want to do
(you show output from a kernel TFTP download, but you talk about
mounting the root file system over NFS - which is a Linux task and as
such totally unrelkated to U-Boot).

Sorry, but due to total lack on vital information we cannot help you.

Best regards,

Wolfgang Denk
