Sorry for the stupid question but: what is tick_arg ? Do I have to configure it within Xenomai or is it a kernel parameter ? The timing of my target in principal is fine. When I set tstart.tv_sec=0; tstart.tv_nsec=0; both to zero, my task gets peiodic (task runs every second). Just when using clock_gettime(CLOCK_REALTIME,&tstart) I get into trouble.
