But it does support free running! There is even an option called "free_running" and this special management message: * TIME_STATUS_NP # designed for use with gPTP and free_running master_offset 0 ingress_time 0 cumulativeScaledRateOffset +0.000000000 scaledLastGmPhaseChange 0 gmTimeBaseIndicator 0 lastGmPhaseChange 0x0000'0000000000000000.0000 gmPresent false gmIdentity e89a8f.fffe.74f796 Thanks, Richard _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
