Hi
I successfully ported our basic IO library to Xenomai with the vxWorks
skin running on our PPC405GPr based HCU4 (which was accepted into Linux
2.6.28). I just added support for one external interrrupt (occurring every
millisecond) and two CAN interrupts (not yet currently activated).
Now my program starts up, recognizes the HW but stops sometimes after 5
seconds, sometimes after 30 seconds. Always with a zombie message. Can anyboy
tell me, where the error is or what I have to check?
I am using svn://svn.gna.org/svn/xenomai/trunk (Revision 4662).
