[lwip-users] UDP-server not working!

[Kai Parow-Souchon]

Hey!

I'm trying to get a simple UDP-server to work on an LM3S8538 stellaris arm.

TCP works great, but my UDP server initialized by:

pcb = udp_new();
udp_bind(pcb, IP_ADDR_ANY, 1338);

udp_recv(pcb, myUDPrcv, NULL);

always returns ICMP "destination unreachable (port unreachable)" 
messages when I try to send a package to it.

In die config file I only defined LWIP_UDP - is there anything else that 
needs to be configured?

I don't have any idea left to try...it's really simple but still doesn't 
work ;)

Any suggestions or anything I can try or have a look at are welcome,
Thanks,
Kai
