Note to previous text ... I am using "Network Packet Generator" to generate Echo Requests, and have validated the correct packetand payload have been receivd and the TSE_Mac statisitcs indicate no error packets and the broadcast packets are corectly being received.
I have tried both the example hardware design available for the board and my own design to no success. No optimisation flags and standard NIOS2. KNown good working DDR2 SDRAM interface design ... running all from same memory.

So... if you run a standard NIOS II Ethernet demo (like simple socket server) from the IDE it won't receive Ethernet packets? If true this would be either SGDMA (as you say below) or the MAC interface within the rest of the design. Be sure to review sample Ethernet designs because the bridging is required. The PHY is clearly working as seen in the debug output.

I suspect maybe something going on with the SGDMA.

Perhaps. If you can get an example to run, then it lets us know it's this lwIP demo not working. Obviously if a NIOS II demo won't run neither will this lwIP demo.
Oh, I forgot this. Does the following link provide anything useful to you?
