Hi,

After staring at the logs, I noticed that duplicate MAC addresses were
used on the
two zynqmp-zcu102. I believe this is the cause of the intermittent
TFTP termination
problem.

So I made those machines use a unique MAC address. Now this problem has been
resolved.

Sorry for the inconvenience.

Best regards,
Hiraku Toyooka
