Hi Team, We are using linuxptp-3.1 version.We are running ptp4l with Primary configuration on a DUT and running ptp4l with salve configuration in another DUT. Both Primary and slaves are connecetd via Radmoon Media converter.
We observed that Primary board is successfully sending sync(in every 125 ms),Follow up message,PDelayResp,PdelayRespFollowUp..etc and slave also sending Peer_Dealy_Req_message and is recived by Primary DUT. The Primary Board system time is also successfully updating in Slave board, however we observed that "rms" vlues in the slave board is >10000000 consistently. When we analyzed the sync packet we found that "LogMessagePeriod: -3" . Could you please let us know in which scenario/case the "LogMessagePeriod: -3" is getting updated in sync packet ? Note : we are running "phc2sys -s eth0 -c CLOCK_REALTIME --step_threshold=1" in slave board Logs: root:~# ./ptp4l -i eth0 -f automotive-slave.cfg -m ptp4l[291.097]: selected /dev/ptp0 as PTP clock ptp4l[291.170]: port 1: INITIALIZING to SLAVE on INIT_COMPLETE ptp4l[291.171]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[292.108]: port 1: new foreign master 0022a0.fffe.000106-1 ptp4l[293.030]: rms 14298871623 max 28633786542 freq +32767999 +/- 0 delay 249550 +/- 0 ptp4l[293.998]: rms 834329141 max 1086841975 freq +32767999 +/- 0 delay 238995 +/- 0 ptp4l[294.966]: rms 656424174 max 1242086770 freq +32767999 +/- 0 delay 228440 +/- 0 ptp4l[295.934]: rms 834413078 max 1086933599 freq +32767999 +/- 0 delay 47601 +/- 0 ptp4l[295.977]: selected best master clock 0022a0.fffe.000106 ptp4l[296.992]: rms 546142504 max 1241973769 freq +32767999 +/- 0 delay 219031 +/- 0 ptp4l[297.919]: rms 910259892 max 1164392370 freq +32767999 +/- 0 delay 217901 +/- 0 ptp4l[298.893]: rms 546157036 max 1242015850 freq +32767999 +/- 0 delay 216772 +/- 0 ptp4l[299.867]: rms 910419317 max 1164606134 freq +32767999 +/- 0 delay 41767 +/- 0 ptp4l[300.821]: rms 546124273 max 1242235894 freq +32767999 +/- 0 delay 216772 +/- 0 ptp4l[301.735]: rms 910078978 max 1164216378 freq +32767999 +/- 0 delay 213509 +/- 0 ptp4l[302.709]: rms 546122078 max 1241845058 freq +32767999 +/- 0 delay 148756 +/- 0 ptp4l[303.682]: rms 910298081 max 1164439875 freq +32767999 +/- 0 delay 142954 +/- 0 ptp4l[304.651]: rms 546142664 max 1242083695 freq +32767999 +/- 0 delay 201156 +/- 0 ptp4l[305.551]: rms 910186093 max 1164323638 freq +32767999 +/- 0 delay 201156 +/- 0 ptp4l[306.524]: rms 546136673 max 1241949998 freq +32767999 +/- 0 delay 189790 +/- 0 ptp4l[307.498]: rms 910274018 max 1164416786 freq +32767999 +/- 0 delay 189790 +/- 0 ptp4l[308.472]: rms 546156330 max 1242043326 freq +32767999 +/- 0 delay 199359 +/- 0 ptp4l[309.381]: rms 910243669 max 1164393419 freq +32767999 +/- 0 delay 201871 +/- 0 ptp4l[310.282]: rms 546152446 max 1242024319 freq +32767999 +/- 0 delay 199359 +/- 0 ptp4l[311.182]: rms 910248741 max 1164373995 freq +32767999 +/- 0 delay 190736 +/- 0 Thanks, Raj
