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

No problem.

So is there a PTP peer device connected on slave 1 (probably =eth1) as
well? That would explain the messages, as the HW+dri

It is not enough to configure the master alone, you must also
configure the slave in P2P mode.

Hello,
Can anybody help me to understand this message
I have a message when I configure GPS to work PTP in Peer-to-Peer mode
ptp4l[18815.624]: port 1: received PDELAY_REQ without timestamp
ptp4l[18815.624]: port 1: received PDELAY_REQ without timestamp

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

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

Offset and Delay are in nanoseconds. The Frequency is (I'm pretty

Hello,
I am working on Linux 3.12 running on TI AM335x.
The Test system is GPS connected to CPU over Ethernet and GPS is configured
to End to End protocol.
following are the messages
