[Xenomai-core] rt_task_create() hangs ?

[Steven Scholz <steven.scholz@domain.hid>]

Hi all,

we're doing the first steps with Xenomai and stumbled about some problems.

On our AT91RM9200 (adeos-ipipe-2.6.14-arm-1.5-04,
ipipe-2.6.14-at91-1.5-04.patch) a simple application (that just creates and
destroys two threads)

	rt_task_create(&task_1,"task_1",0,50,0);
	rt_task_create(&task_2,"task_2",0,51,0);
	...
	rt_task_delete(&task_2);
	rt_task_delete(&task_1);

runs fine when started for the first time. But when started again it hangs
in the rt_task_create() for the second task.
Funny enough it all runs fine when we first delete task1 and then task2 ...

On an x86 (adeos-ipipe-2.6.19-i386-1.6-03) the application runs fine. Either
way.

We noticed that on the AT91RM9200 we don't see the

Xenomai: POSIX: destroyed thread c14a0320

message. Not even when running (and stopping) cyclictest. I suspect that
this is leading to our problems.

Any idea?

Thanks a million!
