[Xenomai-help] Problems with Threads and RTnet

[Karl Reichert]

Hello list,

I have some problems with RTnet and threads. I create two thread via rt_task_spawn(), one is sending and one is receiving (non-blocking) frames over rtnet.

Each task is existed with return (I also tried rt_task_delete()) and the main-function is waiting for task-termination via rt_task_join().

When I run this program the first time, everything is fine. When I run it a second time without rebooting, I can't receive any more frames (returnvalue -1).

So it seems that the termination of the tasks and the main-function from the first run failed to free the "RTnet resources", too.

Any idea, what I'am doing wrong?

Thanks in advance
(... and good luck to the german team, for all the soccer fans out there)
Karl

What version of Xenomai are you running ? Do not you get error messages 
in the console ?

Hello..

I'm a newbie using xenomai domain, and i still don't understand how to write an application in user-space so that xenomai domain recognize it. Do we should use xenomai library and makefile like in the example folder? Can someone explain me?

Sorry, i'm not really experienced in linux kernel and anything about it.. 

Thanx..

For examples using the native API, please read:
http://www.xenomai.org/documentation/branches/v2.3.x/pdf/Native-API-Tour-rev-C.pdf

For the posix skin, see doc/txt/pse51-skin.txt.

You should spend your time reading documentations before your start
asking questions on mailing lists, then.
