phc2sys Waiting for ptp4l...

deepanrajanbara — Thu, 24 Mar 2022 05:22:30 GMT

Hi,

We are using ptp4l in our Ls1046a based custom board and it is able to run in our system and the 1588 pulse is in sync with the system. But when we run phc2sys -s fm1-mac3 -w command for the clock to get the UTC offset from the ptp4l automatically. we are observing "Waiting for ptp4l..." log continuously. the phc2sys is stuck in this state for long time. please help us resolve this issue.

Thank you,

I cannot reproduce your issue, when you observe this issue, could you please check ptp4l is running correctly and keeps synchronizing with master?

Following is my testing log for your reference:

// console1: run ptp4l first to sync your 1588 clock to master # root@ls1046ardb:~/linuxptp# ./ptp4l -i fm1-mac3 -s -m ...

We are actually using g.8275.1 profile and when we run ptp4l we are not getting any isseue. But when we run phc2sys with -w option we are observing waiting for ptp4l . Please let us know, Do we need to do any configuration in ptp4l so that it will be in sync with the phc2sys

Hi ,

Can you please share your config file so that we can also test with the same config file .

Thank you,
