Hello everyone. Following my previous email, I have tried reading the 32-bit time of the reference clock by *ecrt_master_reference_clock_time* in various versions of the library. Here are the results of calling this function in userspace code:
- 1.5.2 (*Failed to get reference clock time: Input/output error*) - stable-1.5 branch of SourceForge (*Failed to get reference clock time: Input/output error*) - default branch of SourceForge. (Returns -5: *Slave synchronization datagram was not received*) - default branch of SourceForge + gavinl's patchset (Returns -5: *Slave synchronization datagram was not received*). - As expected, *ecrt_master_64_bit_reference_clock_time* (in the patched version) also returns -5 (*Slave synchronization datagram was not received* ). - By reading the register "0x92c" on the reference slave, I can verify that the DC mechanism is working as it should. So what is causing the error *Slave synchronization datagram was not received*? Best, Mohsen
