[Xenomai-help] rt_task_start returns -38 (ENOSYS)

[Xenomai-help] rt_task_start returns -38 (ENOSYS)

[martin mangard]

Hello

I installed Xenomai on a x86 machine (kernel 2.6.30 wih xenomai
2.4.10). In order to verify the installation I ran the
latency-testprogram from the test-suite.
The latency test program aborts with the error ENOSYS :


== Sampling period: 100 us
== Test mode: periodic user-mode task
== All results in microseconds
latency: failed to start display task, code -38

This output ist generated if the call err =
rt_task_start(&display_task, &display, NULL); ---> fails.

As mentioned in the documentation this error occurs, if not all
necesary modules are loaded or configured.

during the startup following messages occur:

.
.
I-pipe: Domain Xenomai registered.
Xenomai: hal/i386 started.
Xenomai: real-time nucleus v2.4.10 (Flavor Crystal 7) loaded.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.
Xenomai: starting RTAI emulator.
.
.

Which subsystem do I have to enable in order to be able to  start a
rt_task as used in the latency test program ?

Please send us the full logs, from the boot up to the point where your
program fails.

As well as the "latency" command line which fails.

Hello

I did some more research.
What I haven't memtioned is, that I'm using openembedded to build
xenomai. It turned out that the reason that caused the ENOSYS error
was the same as descibed in:

https://mail.gna.org/public/xenomai-help/2009-08/msg00047.html

I changed the CFLAGS and the latency test program worked without
errors. It seems to me that some people have made xenomai recipes but
none of them made their way into the
openembedded repository. Maybe I will post my recipe in the
openembedded mailinglist to discuss the possibilities of a xenomai
integration in openembedded.

Thanks for your help

Martin

Ok. But maybe we should fix Xenomai too...
