phc2sys Waiting for ptp4l...

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,

Deepanraj.A

The config file is from upstream linuxptp git repo: git://git.code.sf.net/p/linuxptp/code $ ls configs/ automotive-master.cfg default.cfg G.8265.1.cfg G.8275.2.cfg P2P-TC.cfg ts2phc-generic.cfg UNICAST-MASTER.cfg automotive-slave.cfg E2E-TC.cfg G.8275.1.cfg gPTP.cfg snmpd.conf ts2phc-TC.cfg UNICAST-SLAVE.cfg

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 ...

ptp4l[1382.218]: master offset         -8 s2 freq  +16086 path delay      1810

ptp4l[1383.218]: master offset         25 s2 freq  +16116 path delay      1809

ptp4l[1384.218]: master offset        -21 s2 freq  +16078 path delay      1809

ptp4l[1385.218]: master offset          3 s2 freq  +16096 path delay      1809

ptp4l[1386.218]: master offset          3 s2 freq  +16096 path delay      1809

ptp4l[1387.218]: master offset         -5 s2 freq  +16089 path delay      1809

 

// console2: then run phy2sys to sync system clock to 1588 clock root@ls1046ardb:~/linuxptp# ./phc2sys -s fm1-mac3 -w -m ...

phc2sys[1210.948]: CLOCK_REALTIME phc offset       -33 s2 freq  +16135 delay    400

Hi

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,
