I am trying to implement E1.31 (DMX over ethernet) with an mcf52233. It seems opening a UDP connection in the nichelite stack that comes with the 52233 demo will not receive multicast packets. I know that nichelite does not support IGMP, but I understand receiving multicast on a local connected network should be possible without IGMP. So I guess I have 3 questions...
1) Is it possible with nichelite to do what I desire, and I could just be doing something wrong?
2) Is there a free tcpip stack that people are aware of that will support receiving local multicast?
3) Even better than 2, Is there a free tcpip stack usable on the 52233 that supports IGMP?
