Send UDP sockets with rtems with a M5234BCC

[Diego Sanz]

Hello

I am trying to send packets throw UDP sockets, on the board M5234BCC whose
microcontroller is mcf 5234 (coldfire), with RTEMS
The Examples that comes with RTEMS works perfectly, including the loopback
exaqmple.

Well The next code is the application that I am trying to make but doesn't
send anything throw the cable ( I see with the commview program).

Could someone help me and tell me if is there some error?  Thanks!

The code:
