Does /dev/pps0 exist? Does /sys/devices/virtual/pps/pps0 exist?
Yes, both exist.
Do either the assert or clear files in that directory exist and do they
display steadily increasing values in the file (looket at at successive
times)?
Both files exist. assert does show increasing values. clear is empty.
BTW, this is the same on my jessie system where PPS works.
It would really help the reader if you made some indication as to where
a new
file were listed in your dump of various files. Just the name of the
file is
not enough.
I did include the path on the file names.
refclock PPS /dev/pps0 lock NMEA refid PPS
# Settings for 1 update per 1 to 2.5 second seconds
#refclock SHM 0 offset 0.5 delay 0.2 refid NMEA noselect
# Setting for 2, 3, 4, 5, 10 updates per seconds
refclock SHM 0 offset 0.1 delay 0.2 refid NMEA noselect
What feeds the SHM with the NMEA time? Are you also running gpsd?
gpsd is running and working.
What is in the chrony logs (actually you should turn them on)
What options should I specify for logging?
