[etherlab-users] Failed to get reference clock time: Input/output error

[Gavin Lambert]

This is normal for the first few cycles; it takes several cycles for the reference clock to “sync in”.  It should eventually start working.

This is why there’s a patch in the unofficial patchset to suppress the fprintf error when using the usermode library.

Hello everyone.
When I call ecrt_master_reference_clock_time -right after ecrt_master_sync_slave_clocks()- in my userspace code, I get the following error every cycle.
Failed to get reference clock time: Input/output error.
I'm using stable-1.5 branch.
Has anyone been able to resolve this issue?
Best,
Mohsen
