The refclock (i.e. ptp4l+phc2sys) didn't provide any samples. FYI, Google NTP servers uses a nonstandard timescale (leap smear) and must not be combined with standard NTP servers. > 1.

If you add a dummy PTP domain to timemaster.conf before the 44, it should force 44 to use SW timestamping. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
