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...
