Hi,



Your email was referenced in the
http://wiki.enneenne.com/index.php/LinuxPPS_NTPD_support article on
setting up PPS support with NTPD. I’m hoping you’ll be able to help me
with getting my NTPD to sync on the kernel’s PPS signal/event.



I was able to verify that my kernel is getting PPS events by:

1.       Checking dmesg log to ensure that “PPS event on source 0 at
1291626009.999782403” messages were being logged.

2.       Using PPS-TOOLS “pps-test /dev/pps0” to verify that I’m getting
“source 0 - assert 1291623265.999472205, sequence: 894 - clear
0.000000000, sequence: 0” messages.

3.       Using NMEAD simulator to send “GPRMC” sentences at 1PPS
intervals (synced to PPS interrupts).
