2010-08-06 15:42:03 Xenomai Latency Test on BF533-EZKIT

Hello,
I'm useing the 2009R1.1-RC4 release with enabled Xenomai on the BF533-EZKIT (with native, posix and RTDM skin). When I try to run the latency test for a user task, I allways get the following error message:
latency: wait period failed, code -10
This means that the call to rt_task_wait_period fails with errno EWOULDBLOCK. According to the Xenomai documentation this error will be returned if rt_task_set_periodic has not been called for this task, but as you can see in latency.c this function has been called before (and I get no error that the call to this function fails).
Does anybody know whats going wrong?
The latency test for kernel task and timer IRQ does work!
Thank you!
Best Regards,
Rainer

Hi Rainer,
For 2009R1.1-RC4, we can find similar issue as you mentioned, however, for the latest code in trunk, test result shows it's OK, we suggest you to move to the latest. Refer to https://blackfin.uclinux.org/gf/project/uclinux-dist/scmsvn for how to get it.
