Yeah, got it! Sorry for not supplying error code earlier!

In Xeno source:
int xnpod_start_timer (u_long nstick, xnisr_t tickhandler)
[...]
#ifndef CONFIG_XENO_HW_PERIODIC_TIMER
     if (nstick != XN_APERIODIC_TICK)
         return -ENODEV; /* No periodic support */
#endif /* CONFIG_XENO_HW_PERIODIC_TIMER */

..and guess what: I got -ENODEV back on rt_timer_start!

In .config I have
# CONFIG_XENO_HW_PERIODIC_TIMER is not set

So the puzzle is solved!

Just one question: what's the reason why the periodic mode
is disabled by default ?

Thanks & best regards,
Hannes.
