Hi, I synchronized the ptp clock with the below mentioned command and it seems that it is synchronized sudo /usr/sbin/ptp4l -m -f /etc/linuxptp/ptp4l.conf_as_final ptp4l[7344.881]: selected /dev/ptp0 as PTP clock ptp4l[7344.920]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[7344.952]: port 2: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[7344.992]: port 3: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[7345.024]: port 4: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[7345.024]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[7351.106]: port 2: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[7351.106]: selected local clock 70f8e7.fffe.d008a9 as best master ptp4l[7351.106]: assuming the grand master role ptp4l[7351.569]: port 3: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[7351.569]: selected local clock 70f8e7.fffe.d008a9 as best master ptp4l[7351.569]: assuming the grand master role ptp4l[7351.569]: assuming the grand master role ptp4l[7352.621]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[7352.621]: selected local clock 70f8e7.fffe.d008a9 as best master ptp4l[7352.621]: assuming the grand master role ptp4l[7352.621]: assuming the grand master role ptp4l[7352.621]: assuming the grand master role ptp4l[7352.666]: port 4: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[7352.667]: selected local clock 70f8e7.fffe.d008a9 as best master ptp4l[7352.667]: assuming the grand master role ptp4l[7352.667]: assuming the grand master role ptp4l[7352.667]: assuming the grand master role ptp4l[7352.667]: assuming the grand master role ptp4l[7359.108]: port 2: new foreign master 70f8e7.fffe.d008ae-2 ptp4l[7363.108]: selected best master clock 00304a.fffe.5f00e1 ptp4l[7363.108]: running in a temporal vortex ptp4l[7363.108]: port 2: MASTER to UNCALIBRATED on RS_SLAVE ptp4l[7364.234]: port 2: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED ptp4l[7364.859]: rms 12469 max 24941 freq -96161 +/- 461 delay -1 +/- 0 ptp4l[7365.859]: rms 103 max 180 freq -95925 +/- 145 delay -1 +/- 0 ptp4l[7366.859]: rms 158 max 182 freq -95606 +/- 51 delay -3 +/- 0 ptp4l[7367.860]: rms 112 max 137 freq -95525 +/- 12 delay -3 +/- 0 ptp4l[7368.860]: rms 43 max 74 freq -95547 +/- 18 delay -3 +/- 0 ptp4l[7369.860]: rms 13 max 25 freq -95601 +/- 14 delay -3 +/- 0 ptp4l[7370.861]: rms 23 max 34 freq -95634 +/- 12 delay -3 +/- 0 ptp4l[7371.861]: rms 12 max 25 freq -95631 +/- 14 delay -3 +/- 0 ptp4l[7372.861]: rms 11 max 25 freq -95627 +/- 15 delay -3 +/- 0 ptp4l[7373.861]: rms 8 max 11 freq -95620 +/- 10 delay -3 +/- 0 ptp4l[7374.861]: rms 12 max 20 freq -95608 +/- 13 delay -3 +/- 0 ptp4l[7375.862]: rms 13 max 20 freq -95590 +/- 6 delay -3 +/- 0 ptp4l[7376.862]: rms 9 max 20 freq -95596 +/- 12 delay -3 +/- 0 ptp4l[7377.862]: rms 12 max 16 freq -95613 +/- 14 delay -3 +/- 0 ptp4l[7378.862]: rms 9 max 18 freq -95610 +/- 12 delay -1 +/- 0 ptp4l[7379.863]: rms 11 max 18 freq -95598 +/- 13 delay -1 +/- 0 ptp4l[7380.863]: rms 12 max 28 freq -95616 +/- 14 delay 0 +/- 0 ptp4l[7381.863]: rms 11 max 19 freq -95625 +/- 11 delay 0 +/- 0 ptp4l[7382.863]: rms 10 max 20 freq -95630 +/- 11 delay 1 +/- 0 ptp4l[7383.863]: rms 7 max 17 freq -95622 +/- 9 delay 0 +/- 0 ptp4l[7384.864]: rms 14 max 26 freq -95609 +/- 17 delay 0 +/- 0 ptp4l[7385.864]: rms 13 max 17 freq -95596 +/- 12 delay 0 +/- 0 ptp4l[7386.864]: rms 11 max 19 freq -95613 +/- 15 delay 0 +/- 0 ptp4l[7387.864]: rms 23 max 37 freq -95650 +/- 11 delay 0 +/- 0 ptp4l[7388.865]: rms 9 max 19 freq -95637 +/- 12 delay 0 +/- 0 ptp4l[7389.865]: rms 6 max 10 freq -95642 +/- 6 delay 0 +/- 0 ptp4l[7390.865]: rms 6 max 10 freq -95635 +/- 8 delay 0 +/- 0 ptp4l[7391.865]: rms 9 max 17 freq -95638 +/- 13 delay 0 +/- 0 ptp4l[7392.866]: rms 12 max 19 freq -95643 +/- 16 delay 0 +/- 0 ptp4l[7393.866]: rms 11 max 20 freq -95655 +/- 12 delay 1 +/- 0 ptp4l[7394.866]: rms 6 max 11 freq -95646 +/- 9 delay 1 +/- 0 ptp4l[7395.866]: rms 10 max 20 freq -95649 +/- 13 delay 1 +/- 0 ptp4l[7396.867]: rms 10 max 16 freq -95638 +/- 12 delay 1 +/- 0 ptp4l[7397.867]: rms 10 max 16 freq -95638 +/- 14 delay 1 +/- 0 ptp4l[7398.867]: rms 13 max 29 freq -95653 +/- 15 delay 1 +/- 0 ptp4l[7399.867]: rms 12 max 27 freq -95662 +/- 14 delay -1 +/- 0 ptp4l[7400.868]: rms 9 max 11 freq -95669 +/- 9 delay 1 +/- 0 ptp4l[7401.868]: rms 9 max 11 freq -95676 +/- 8 delay 1 +/- 0 ptp4l[7402.868]: rms 14 max 20 freq -95678 +/- 19 delay 1 +/- 0 ptp4l[7403.868]: rms 13 max 29 freq -95684 +/- 17 delay 1 +/- 0 ptp4l[7404.869]: rms 17 max 27 freq -95660 +/- 18 delay -1 +/- 0 ptp4l[7405.869]: rms 19 max 27 freq -95696 +/- 18 delay -1 +/- 0 ptp4l[7406.869]: rms 18 max 29 freq -95715 +/- 13 delay 1 +/- 0
but when I am running the phc2sys with the below mentioned command the offset is around 3 to 4 digit which is much larger and i think they are not synchronized. sudo phc2sys -s eth0 --step_threshold 0.0002 --first_step_threshold 0.0002 -f /etc/linuxptp/phc2sys.conf -O 0 phc2sys[7366.414]: CLOCK_REALTIME phc offset -79030 s0 freq -178503 delay 770 phc2sys[7367.415]: CLOCK_REALTIME phc offset -79685 s2 freq -179158 delay 760 phc2sys[7368.416]: CLOCK_REALTIME phc offset -79949 s2 freq -259107 delay 760 phc2sys[7369.417]: CLOCK_REALTIME phc offset -192 s2 freq -203334 delay 770 phc2sys[7370.417]: CLOCK_REALTIME phc offset 23133 s2 freq -180067 delay 770 phc2sys[7371.417]: CLOCK_REALTIME phc offset 23347 s2 freq -172913 delay 760 phc2sys[7372.418]: CLOCK_REALTIME phc offset 15393 s2 freq -173863 delay 761 phc2sys[7373.418]: CLOCK_REALTIME phc offset 9048 s2 freq -175590 delay 770 phc2sys[7374.418]: CLOCK_REALTIME phc offset 4761 s2 freq -177163 delay 761 phc2sys[7375.418]: CLOCK_REALTIME phc offset 2562 s2 freq -177933 delay 760 phc2sys[7376.418]: CLOCK_REALTIME phc offset 830 s2 freq -178897 delay 770 phc2sys[7377.419]: CLOCK_REALTIME phc offset 454 s2 freq -179024 delay 760 phc2sys[7378.419]: CLOCK_REALTIME phc offset -371 s2 freq -179712 delay 760 phc2sys[7379.419]: CLOCK_REALTIME phc offset -830 s2 freq -180283 delay 760 phc2sys[7380.419]: CLOCK_REALTIME phc offset -965 s2 freq -180667 delay 761 phc2sys[7381.419]: CLOCK_REALTIME phc offset 47 s2 freq -179944 delay 760 phc2sys[7382.420]: CLOCK_REALTIME phc offset 211 s2 freq -179766 delay 770 phc2sys[7383.420]: CLOCK_REALTIME phc offset 970 s2 freq -178944 delay 770 phc2sys[7384.420]: CLOCK_REALTIME phc offset 675 s2 freq -178948 delay 770 phc2sys[7385.420]: CLOCK_REALTIME phc offset 102 s2 freq -179318 delay 760 phc2sys[7386.420]: CLOCK_REALTIME phc offset -151 s2 freq -179541 delay 760 phc2sys[7387.421]: CLOCK_REALTIME phc offset 41 s2 freq -179394 delay 770 phc2sys[7388.421]: CLOCK_REALTIME phc offset 936 s2 freq -178487 delay 760 phc2sys[7389.421]: CLOCK_REALTIME phc offset 989 s2 freq -178153 delay 770 phc2sys[7390.421]: CLOCK_REALTIME phc offset 165 s2 freq -178680 delay 760 phc2sys[7391.421]: CLOCK_REALTIME phc offset 119 s2 freq -178677 delay 770 phc2sys[7392.422]: CLOCK_REALTIME phc offset 673 s2 freq -178087 delay 770 phc2sys[7393.422]: CLOCK_REALTIME phc offset -434 s2 freq -178992 delay 770 phc2sys[7394.422]: CLOCK_REALTIME phc offset -547 s2 freq -179235 delay 760 phc2sys[7395.422]: CLOCK_REALTIME phc offset -975 s2 freq -179827 delay 770 phc2sys[7396.422]: CLOCK_REALTIME phc offset -1678 s2 freq -180823 delay 760 Thanks a lot.
