Thanks Richard! I added the following to the end ptp4l.conf: [unicast_master_table] table_id 1 logQueryInterval 2 UDPv4 192.168.0.250 # [eth0] unicast_master_table ... and started ptp4l with: ptp4l -p /dev/ptp0 -i eth0 -f /etc/ptp4l.conf -m -q -l 7 -H -s And kind of get the same result (but with unicast messages now): ptp4l[8367.195]: cooot@imx8mmevk:/etc# ptp4l -p /dev/ptp0 -i eth0 -f /etc/ptp4l.conf -m -q -l
