Hello,
As the subject line suggests, I would like to set up FreeBSD 6.2 to use my
Garmin GPS 18 LVC as a refclock.
I've been following advice from David Taylor's web page on this subject
http://www.david-taylor.myby.co.uk/ntp/FreeBSD-GPS-PPS.htm , although he
used FreeBSD 5.4.
I have a few questions regarding the configuration. I understand that
'options PPS_SYNC' needs to be added to the kernel config file, and that the
kernel then needs to be recompiled. However, he includes a comment from
Harlan Stenn stating that 'include GENERIC', 'ident PPS-GENERIC', and
'options PPS_SYNC' need to be added to the file /usr/src/sys/i386/conf/PPS .
This file doesn't exist on my system. Do I need to create the file from
scratch with those items in it, or is it something that is created after the
kernel recompile?
I emailed David Taylor with these questions regarding the configuration, and
he replied that he can't quite remember exactly how he configured his
system, and if that PPS file needed to be created from scratch or not. So
he directed me to the newsgroup.
If someone could give me a complete list of steps that need to be taken to
configure FreeBSD to use the GPS 18 LVC, or point me to some documentation
on the matter, I would greatly appreciate it. I'm new to FreeBSD and don't
know my way around.
Thanks!
