[etherlab-users] DC question: "Failed to get reference clock time: Input/Output error"?

[Jiarui Lian]

Hi Everybody:

I tried to synchronize master clock to a reference-slave-EK1100 (due to Master clock jitter):
* Based on the example of "examples/rtai_rtdm_dc".
* I modified the example, since I am using RT-Preempt instead of RTAI.
* But I got error: "Failed to get reference clock time: Input/Output error"?
--- (And I found that the error message comes from function "ecrt_master_reference_clock_time()")

Graeme and Tommaso have some discussions on this issue before, but not sure if it is solved:

Anybody solved the problem and hints?
Thanks!
