In theory (completely untested air code) something like this might be more
correct:
cycle = sync0->cycle_time + sync1->cycle_time – (sync1->cycle_time %
sync0->cycle_time);

Why are you adjusting dc_sync[0] from sync1_*? That doesn’t seem like it would
ever be a sensible thing to do, unless I’m missing something.

It is generally not possible to reboot a slave by using register requests
There are a few different kinds of API to do SDO transfers, depending on how
and when you want to do them. (But in short: no, that code is probably not
correct.)
ecrt_master_sdo_download/upload are blocking APIs; they are intended to be
called before activating the master. It is still

As noted, the three register writes must be received on three consecutive
frames, otherwise the ESC will ignore them. (Also, some
urn -1;
cycle_task();

What could be wrong?
