Hi,
So I think I have ptp4l running ok:
ethtool -T eth0
Time stamping parameters for eth0:
Capabilities:
hardware-transmit (SOF_TIMESTAMPING_TX_HARDWARE)
software-transmit (SOF_TIMESTAMPING_TX_SOFTWARE)
hardware-receive (SOF_TIMESTAMPING_RX_HARDWARE)
software-receive (SOF_TIMESTAMPING_RX_SOFTWARE)
software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
hardware-raw-clock (SOF_TIMESTAMPING_RAW_HARDWARE)
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes:
off (HWTSTAMP_TX_OFF)
on (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
none (HWTSTAMP_FILTER_NONE)
all (HWTSTAMP_FILTER_ALL)
And when I run ptp4l from command line I get:
# ptp4l -i eth0 -f /etc/linuxptp/ptp4l.conf -m -q -l 7 -s

... but when I try to run phc2sys with the -m option all I get is "Waiting for
ptp4l..."
I've tried phc2sys -a -r -m, phc2sys -s eth0 -c CLOCK_REALTIME -w -m and a
bunch of other combinations with same result.
So I'm not understanding something or doing something right. I'm not even 100%
if I even need to be running phc2sys.
Also, I tried to make ptp4l start as a service with systemd. When I do a 'ps'
I see it's started at bootup but can't see if it's synced properly. I'm
basically using NXP's Yocto build for the IMX8 Mini and have busybox versions
of syslog etc. When I look at /var/log/messages I don't see any ptp4l related
messages and when I try to run any of the pmc commands nothing comes back at
all.
I've tried:
pmc -u -b 0 'GET TIME_STATUS_NP'
pmc -u -b 0 'GET CURRENT_DATA_SET'
... and get nothing.
Any ideas how I can tell if the ptp4l service is synced up properly???

Brian
