Dear John,
Thank you for your replying.

Not yet. I will try it soon. However from the information on the LL_TEMAC, it
seems everything is fine and it should work.

Yes. I used NFS before. I can make sure my NFS server works well. Also in
principle, static IP should get a same result as DHCP, I think.

I just pulled the Xilinx tree quite recently. I am using a latest kernel.

And I’m assuming you have used the NFS root before so you know that it’s good
for sure.
I test on the ML405 with NFS root and haven’t seen this problem, but my setup
is a little different. I use DHCP rather than a static IP, but other than that
it’s similar.
I’m assuming that you accidentally got 2 different powerup outputs in the
message below as the 1st stops and a 2nd starts in the middle.
How long has it been since you pulled from the Xilinx Git tree?
Thanks,
John
