I have simular issue. I have setup the NIOS udp client but when a broadcast message is sent out on the network my receive led flashes but my break point in the udp.c file does not get hit. If I send a regular udp message it does? Whats that all about..

mask = 0xFFFFFF00

IP = 192.168.31.44

PC is broadcasting SO_BROADCAST out

mask 0xFFFFFF00

IP = 192.168.31.45

Used 192.168.31.45 to send out broadcast..

Used 239.0.0.31 to send out broadcast.. above NIOS gets neithe but will receive
