Forget this, the issue is still present. Damn!
It's at least a little clearer to me what happens now. The FEC fails to transmit an TFTP block ACK packet -> the server waits 5 seconds -> sends ARP packet -> FEC replies and resends the TFTP block ACK again. Why does the FEC swallow a TX packet, I don't know.
Anyway, it is strange that this happens only with this board. It appears as the SOC sends or thinks to have sent, but the packet is corrupted or not sent at all on the physical layer. Maybe you can check on the other side of the connection on the switch and/or on the server, if some errors are detected.
Best regards, Stefano Babic
