You should increase the threshold. If you want to synchronize to the average offset instead of sticking to the first measurement, you can use the PI servo with small constants. > Output: > port 1: SLAVE to UNCALIBRATED on SYNCHRONIZATION_FAULT > rms 4 max 10 freq +0 +/- 0 delay 7173 +/- 0 > port 1: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED > port 1: SLAVE to UNCALIBRATED on SYNCHRONIZATION_FAULT > port 1: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED > rms 4 max 7 freq +0 +/- 0 delay 7172 +/- 0 -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
