That explains it. I don't think dual emac and cpts will work together.
At least I never tested it.

No problem.

And are you using dual_emac mode?

So is there a PTP peer device connected on slave 1 (probably =eth1) as

Then you need to measure it, using a PPS signal for example.

The path delay is the measured Ethernet
I would like to know the accuracy of time synchronization ?
And the difference between path delay and master offset ?
