Dear Richard,
I'm trying to sync dates in-between two system(NPX based chipset
MPC8313), by making one master while another one slave, by using ptp4l
and phc2sys commands.
But after running "phc2sys" in slave, date is showing some random date.
Below are the log messages,
Kindly help me to figure out what went wrong here...
