hi, We are using ptp3.0 version in C3 mode. Both ptp4l and phc2sys (to sync system clock) are running fine.
Ptp4l rms value is in single digits and we see a sudden jump in phc offset as captured below resulting in date change. Oct 26 19:15:48 phc2sys_slave: [1177711.923] CLOCK_REALTIME phc offset -97 s2 freq +3454 delay 2479 Oct 26 19:15:49 ptp4l_slave: [1177712.827] rms 3 max 7 freq -2363 +/- 5 delay 86 +/- 1 Oct 26 19:15:49 phc2sys_slave: [1177712.924] CLOCK_REALTIME phc offset -61 s2 freq +3461 delay 2433 Oct 12 05:18:20 ptp4l_slave: [1177713.819] rms 3 max 8 freq -2364 +/- 5 delay 86 +/- 1 Oct 19 08:03:31 phc2sys_slave: [1177713.924] clockcheck: clock jumped backward or running slower than expected!

Please suggest. regards, Ramesh _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
