I am running uBoot on a DM6646 DSP and am not able to see an ARP Response from the network. When using the Davinci EVM board, I send out a ping and while monitoring the Ethernet traffic. I see an ARP Request from the DSP, Arp Response from my PC, and then an Echo Request from the DSP. When I try this with my custom board, I never get an Echo Request. I have verified that the receive signals going from the PHY to the DSP are present.

 

I am using a Marvell 88E3018 PHY where the Davinci EVM board uses an Intel PHY. I have not verified whether this is a hardware or software problem, where uBoot may need to be modified.

 

Any help is appreciated,
