Packets are not received

[JochiSt]

Dear all,

I tried using liteeth on a Nexys4 board. But somehow, I'm not able to receive any UDP packet at all. I tried the raw as well as the streaming mode, but always the source_valid stays low.

Pinging the Board works fine. Hence I would conclude, that the implementation is somehow working.

You can find all files in my repository https://github.com/JochiSt/Nexys4-liteeth - I used the generator to get a verilog file, which I used in my VHDL design.

Any opinions, why there is no packet received by my liteeth implementation?
