 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 ?
    

No, please try Xenomai trunk:
https://gna.org/svn/?group=xenomai

Yes, it works.

But i have one question.
The main trunk is stable or every change is uploaded ?

For me it's very important because i can't upgrade the board very frequently.

Roberto
