Subject: [Xenomai-help] unexpected rt_task_sleep behaviour
Date: Wed, 15 Jun 2011 14:02:00 +0200	[thread overview]
Message-ID: <1308139320.2568.7.camel@domain.hid> (raw)

Hi,

I am using a KARO TX-51 board (imx 515) running linux 2.6.31.12 + karo
supplied bsp patches. Xenomai is at version 2.5.6

In a userspace task i create an interrupt, and want to wait for 1 to 14
ms. If I supply any non zero delay to rt_task_sleep, I get a delay of
830 ms (measured on scope) no matter what delay argument i use.

It seems something got wrong with the adeos patch. I also experience
that the serial console is quite laggy.

 Can anyone give me some pointers where to start investigating this
matter?

Regards,
Christian
