So you see the ping packets arrive on the target, but don't see a reply on
the host? The thing to check is whether the target is trying to send
anything at all. Firstly use a packet sniffer to see if the target is
sending something, but invalid. Secondly debug the net stack (over serial!)
to see if it attempts to transmit a reponse.
