Hi,

i try to use rt_task_sleep( 10000000 ) in a user-space task under
round-robin scheduling but doesnt' work.
        
Do not forget that the number passed to rt_task_sleep is a count of
ticks (and documented as such), so, if you want to sleep for 10ms, you
should call:
rt_task_sleep(rt_timer_ns2ticks(10000000))
      
i try also this but nothing is changed.
    

Of course, but about the other question: do you observe the same
behaviour with xenomai trunk ?
What do you mean  xenomai trunk ?

this is my actual configuration:
 - xenomai-2.4-rc5
 - kernel 2.6.20.4 arm cirrus ep9315 patched

have i try with xenomai 2.4.1 ?

thanks
