I haven't looked in detail but it sounds like the packets aren't
getting through to lwIP. I'm afraid I don't know enough about the
board you're using to suggest how to debug it though.
Might be an obvious question, but have you started up the network interface
over which you wish to pass data? You mentioned PPP, is it dial up or PPPoE
for example? You might be thinking that LwIP does this for you - it
doesn't. You need to establish the low level link you wish to use (e.g. if
dial up PPP, then start the modem connection) before trying to send any data.
Hope this helps,
