Yes, tried several

• How do you know it isn't receiving packets?

• How do you know it is transmitting packets?  Have you sniffed your

ether with ethereal and verified the Tx packets are properly formed (see next bullet)?

I see ARP requests on the host machine, using tcpdump.

• Are you sure your IP address and MAC are OK (WARNING: arbitrarily

chosen MACs always seem to be illegal -- must be a corollary to Murphy's law)

I'm using MAC address assigned for out internal use.

• Are you aware that u-boot does not respond to "ping" (you can ping

another machine from the command prompt, but u-boot won't respond if you ping _it_ from another machine)?

I'm pinging from u-boot to host.

Is the board connected to the LAN using hub? If yes, try switch. There can be problems with half-duplex link.

I've tried both a hub & switch. One odd thing was that the hub was reporting half duplex, but the board was report full. I tried modifying the fcc_psmr to match, but that only made things worse.

I need to try using the other ethernet port and see what happens.
