Hello,
We encounter a problem in a particular situation. In the attached
source, when we change the value passed to rt_task_sleep (line 35), the
program never returns.
This appears only with values greater or equal to 100000 (and maybe some
other values between 10000 and 100000) and only when we use
rt_task_sleep between the two rt_task_spawn calls.
Is there something we've done wrong ?
We use and Armadeus APF27 platform. I don't know if this behavior is
related to this architecture, to Xenomai or both.
