Alessandro,
Put this line (I'm not sure about rtudp.ko or rt_udp.ko. U should verify it
in the rtnet directory)
*insmod ${RTNET_MOD_DIR}/rtudp.ko
* after
insmod ${RTNET_MOD_DIR}/rt_loopback.
ko
This line must be added in the loadRTnet file of C4GOpen Library, if u use
the newest RTnet's versions. Good luck with C4GOpen. It's a powerfull tool.
Att,
