It seems that was my fault. I was using a busy send/receive loop to wait
the OP state on all slaves:
for (...) {
ecrt_master_send(master);
usleep(...);
ecrt_master_receive(master);
ecrt_master_state(master, &state);
if (state.al_states == EC_AL_STATE_OP) {
return done;
}
}
This does not process data, as I thought that was not needed during
configuration. Adding `ecrt_domain_process()` before sending and
`ecrt_domain_process() after receiving solves the problem.
Ciao.
