I think many people have seen this thread, the problem I still can’t fix it.

I have a good news , I can just use the udp code with nios on EP3C25F324 and the speed is 4.55MB/s. But last night, I have found another problem.

Now I can send package of 1024 bytes or 512bytes,it works well. But when I increase the number to 2048 or 156 bytes one package, I saw the net tx led is blinking ,but the Wireshark can get nongthing.

I don’t know why??
