Hi,
I have a problem to sync two pc's.
1: Linux laptop with 5.4.5-rt3 kernel
2: Linux PC with 4.9.115-rt93 Kernel and I210 interface
I start the ptp4l master on my pc (2) with:
sudo daemonize -E BUILD_ID=dontKillMe -o /var/log/ptp4l.log -e
/var/log/ptp4l.err.log /usr/bin/taskset -c 1 chrt 90 /usr/local/sbin/ptp4l
-i enp3s0 -2 -mq -f /etc/linuxptp/gPTP.cfg --step_threshold=1
--fault_reset_interval=0 --announceReceiptTimeout=10
sudo pmc -u -b 0 -t 1 "SET GRANDMASTER_SETTINGS_NP clockClass 248
clockAccuracy 0xfe offsetScaledLogVariance 0xffff currentUtcOffset 37
leap61 0 leap59 0 currentUtcOffsetValid 1 ptpTimescale 1 timeTraceable 1
frequencyTraceable 0 timeSource 0xa0"
sudo daemonize -E BUILD_ID=dontKillMe -o /var/log/phc2sys.log -e
/var/log/phc2sys.err.log /usr/bin/taskset -c 1 chrt 89
/usr/local/sbin/phc2sys -s enp3s0 -c CLOCK_REALTIME --step_threshold=1 -w -m
I got no error logs but after a short time I got the following status:
● ptp4l.service - Precision Time Protocol (PTP) service

grand master role
on my laptop (1) I start the slave with:
sudo daemonize -E BUILD_ID=dontKillMe -o /var/log/ptp4l.log -e
/var/log/ptp4l.err.log /usr/bin/taskset -c 1 chrt 90 /usr/local/sbin/ptp4l

sudo daemonize -E BUILD_ID=dontKillMe -o /var/log/phc2sys.log -e
/var/log/phc2sys.err.log /usr/bin/taskset -c 1 chrt 89
/usr/local/sbin/phc2sys -s enp0s31f6 -c CLOCK_REALTIME --step_threshold=1
-w -m
the ptp4l error log shows:
ptp4l[26624.453]: port 1: master state recommended in slave only mode
ptp4l[26624.453]: port 1: defaultDS.priority1 probably misconfigured
ptp4l[30399.153]: timed out while polling for tx timestamp
ptp4l[30399.153]: increasing tx_timestamp_timeout may correct this issue,
but it is likely caused by a driver bug
ptp4l[30399.153]: port 1: send peer delay response failed
ptp4l[31677.494]: port 1: received PDELAY_RESP without timestamp
I am happy about every suggestion.
Best wishes
Marcel
