Hi Richard,
I get a strange behavior when using "free_running 1". The summary looks
like this:
$ ptp4l -f /etc/ptp4l.conf -i eth1 -m
ptp4l[3620445.368]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[3620445.368]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[3620445.600]: port 1: new foreign master 008063.fffe.b6706b-13
ptp4l[3620447.600]: selected best master clock 00606e.fffe.7c230f
ptp4l[3620447.600]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[3620448.515]: port 1: minimum delay request interval 2^3
ptp4l[3620452.600]: rms 34999153762 max 34999173342 freq -19583 +/- 2
delay 7694 +/- 246
ptp4l[3620456.599]: rms 34999231855 max 34999251436 freq -19587 +/- 3
delay 5256 +/- 0
ptp4l[3620460.599]: rms 34999309648 max 34999328697 freq -19591 +/- 8
delay 5141 +/- 0
ptp4l[3620464.599]: rms 34999387468 max 34999407058 freq -19592 +/- 0
ptp4l[3620468.598]: rms 34999465846 max 34999485433 freq -19595 +/- 7
Querying ptp4l using pmc gives this output (note the first
offsetFromMaster value):
$ pmc -u "get CURRENT_DATA_SET"
sending: GET CURRENT_DATA_SET
001b21.fffe.929906-0 seq 0 RESPONSE MANAGMENT CURRENT_DATA_SET
stepsRemoved 2
offsetFromMaster -35000968295.0
meanPathDelay 5354.0
008063.fffe.b6706b-13 seq 0 RESPONSE MANAGMENT CURRENT_DATA_SET
stepsRemoved 1
offsetFromMaster -33.0
meanPathDelay 87.4
000b72.fffe.0585b6-1 seq 0 RESPONSE MANAGMENT CURRENT_DATA_SET
stepsRemoved 2
offsetFromMaster -2.0
meanPathDelay 3818.0
Everything is fine as soon as I use "free_running 0".
Regards,
Tino
