/Hello Ravi,

Which runtime enviroment do you use?

Xenomai/RTAI?
Kernelversion ?
Distro?

My configuration
Debian squeeze

Xenomai
Kernel 2.6.35.9
Xenomai 2.5.6

RTAI
Kernel 2.6.32.11
RTAI 3.8.1


You need the master_send_ext for using async communication like EoE,...

 Hi Andreas,

 Thanks for the reply.

 I could not somehow get it going with 2026, I probably should be
 looking at why it didn't work. But after a couple of reboots from
 kernel crashes, I thought I was better off with the newer version.

 Below is my effort so far.  I disabled application_callbacks because
 it seems that with that on, the system would freeze after the
 application had finished a given cycle, but the system appears to
 still be processing in the background, because the link light
 flashes.

 With the changes below, the cycle works (and the system does not
 freeze), and I get sensible time measurements for e.g. time spent in
 ecrt_rtdm_master_recieve(),

 however I do not seem to be able to exchange any domain data in both
 directions (it is zero all the time).

 I had a brief look at how the domain calls (queque, process) are
 being shuttled between RTDM, and it appears to be correct -
 afaics...
