simple socket sever is running,but cann't ping/telnet

Hi,

I am having EXACTLY this problem. I have used the standard design from the kit. I have had a field rep try the same thing, and get the same effect.

It has been a very frustrating couple of weeks, and I am starting to doubt my sanity.

I have tried the standalone lwip and I get a similar effect.

Signal Tap shows packets correct on rgmii

TSER_MAC statistics show correct broadcast ping statistics.

Breakpoints in low level input show no packets received as always returning a null.

Has anyone found a solution to this problem?

Any advice appreciated!
