Nope, it's too good to be true. When using RTnet with RTAI, you have to keep in mind that RTAI's system timer requires manual start-up, either in your main application (rt_timer_start or so) or via one RTnet module that needs it too (tdma.ko or rtcfg.ko - but you don't need any of them for your scenario). > > Regards, > > Leo > > Pd it not localhost.
