Hi all,
I have two PCs synchronized with linuxptp (V1.4 or V1.5 - the question is valid
for both versions).
On both PCs I run the following commands:
/usr/local/sbin/ptp4l -i eth1 -p /dev/ptp1 -f /etc/linuxptp.conf
and
/usr/local/sbin/phc2sys -s /dev/ptp1 -w -u 15 -l 6
This works and I can see in the log file of the PCs the synchronization
accuracy.
Example of the logging in my system logfile:
Jan 7 13:23:59 pcA phc2sys: [2964.861] rms 17 max 31 freq -8176 +/- 18
delay 2687 +/- 21
Jan 7 13:24:14 pcA phc2sys: [2979.862] rms 19 max 46 freq -8167 +/- 18
delay 2690 +/- 20
Jan 7 13:24:29 pcA phc2sys: [2994.863] rms 23 max 45 freq -8158 +/- 20
delay 2690 +/- 24
or from the second PC:
Jan 7 13:23:59 pcB phc2sys: [2974.050] rms 16 max 38 freq +1822 +/- 18
delay 5750 +/- 33
Jan 7 13:24:14 pcB phc2sys: [2989.051] rms 24 max 53 freq +1837 +/- 21
delay 5755 +/- 87
Jan 7 13:24:29 pcB phc2sys: [3004.053] rms 16 max 34 freq +1850 +/- 13
delay 5736 +/- 84
Is it possible to get these values from phc2sys directly without the need to
parse the logfile?
The background of the question is that I have to wait for the start of my
proprietary application until the clocks of the PCs run in a well synchronized
state.
Or what is the recommendation for this use case?
Thanks for any help on this question.
Best Regards
Mathias
