When I configure rati-enable = yes, use /example/Rtai-rtdm-dc as a
reference ,I use rt_get_time_ns() to get the system time and
rt_sleep_until() to sleep the realtime task . It work well with BECKHOFF's
driver AX5101.
But, when I configure xenomai-enable =yes , use
rt_timer_tsc2ns(rt_timer_tsc()) to get the system time and
rt_task_sleep_until() to sleep the realtime task. The master laways print:
EtherCAT 0 :Domain 0: 2 working counter changes -now 3/3
And sometimes:
"Synchronization error"
Why?
Thanks
