Hello, i have a problem with ethernet. When i use the eth_stub_send() function the message is always sent twice! But i know the function is only called once. I send double messages and I don't know the solution. Can you help me? Thanks. Regards
Veronica

Try using two tx buffer decriptors rather than one (which I assume you presently have). My experience is that a frame in a single buffer description is always sent twice, which never happens when more than one buffer is available. You can also prepare the frame to be transmitted to be chained in 2 buffer descriptions (eg. IP part in first and UDP etc. part in second). which shoud stop it happening.

If you find another solution, please also let us know!!

Regards
