/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...
