your env is missing an ethaddr

Dunno from the given information, maybe it is the missing ethaddr. I can
confirm that loading data via tftp is working on my d34 device. I think
Bo has an d31 handy and could help you.

To get the original code onto your device you could use the sam-ba
application. It's working on Win and Linux, unfortunately not on OS X.
Just plug the provided USB cable into the J20 on your baseboard (not the
J-Link!), switch J9 correclty (I think open it), push and hold PB4 and
push/release PB1, after that sequence startup sam-ba, choose the correct
interface and the 'at91sama5d3x-ek' board.
