I guess you're right, although I can't find a reason, why the slave
should not work without DC, especially when oversampling is inactive...

You could try to allocate an ec_datagram_t and write the appropriate
register before ecrt_master_activate(). Is the specification available

Mhmm, yes, I think I will implement this in the near future. Those
oversampling devices are interesting for us, too. But I don't know, if
it will make it into the next release. My schedule is still overfull...
