NIC1 Linux software stack:
NIC1 configuration:
1. Run ts2phc to get time from the GNSS:
# ts2phc -f config.cfg -s nmea -c ens1f0
2. You can also use NMEA to get time from both adapters (both adapters need GNSS antenna plugged
in):
# ts2phc -f config.cfg -s nmea -c ens1f0 -c ens2f0
3. Enable 1PPS out on U.FL1:
# echo 2 1 > /sys/class/net/ens1f0/device/ptp/ptp*/pins/U.FL1
4. Run ptp4l:
# ptp4l -m -f config.cfg -i ens1f0 -i ens1f1 -i ens1f2 -i ens1f3
5. Run phc2sys to synchronize system time to the PHC time:
# phc2sys -s ens1f0 -c CLOCK_REALTIME -w -m
