BeagleBone Black NTP server
Has anyone here made NTP run on BBB? My plan is to run NTP disciplined by
my Trimble Thunderbolt on BBB. If someone has gotten there ahead of me I
would like to follow in your footsteps rather than finding the mines in the
minefield all by myself. :-)

I'm running NTP on it now, but not with GPS timing.
I too have ntp running on the BeagleBone Black, also without GPS interfaced.
However, I stumbled across this website;
with details on interfacing GPS but I haven't dug into the details yet
but it looks like a good start.

Ok. Did you build from source or did you have binaries?

I used the distribution of ntp provided in the Angstrom repository.
I believe there is a version of Debian available for the Beaglebone
Black and that too will have ntp in it's repository.

NTP is likely already installed on the BBB. It ships with the BBB. Some
configuration is needed to enable the service. Do this first and verify
you can run using Internet pool servers. Then after this is running you
physically connect your GPS then add lines in NTP's config file telling NTP
you have added another ref. clock.

Wow! Yes. The Debian packages are all out there. I am making a custom
"cape" that just brings the 5V 1pps in and converts it to 3.3V for
compatibility with the BBB.
First step is to configure ntp to run and then add in the hardware support
for 1pps and taking to the T-bolt. I will keep all apprised of my progress.
Thank you much!

That may be the case for the Angstrom distro but it is not the case for the
Debian distro, which seems to be the future direction of BBB.

Seems to have the bulk of the requisite information including building a
GPS cape using the Adafruit GPS module. See:
https://www.adafruit.com/product/746
This isn't a timing receiver but would probably be adequate for NTP. But
since I already have a T-bolt I figured I would use that as my timing
source.

I have the adafruit and a ublox-6T each mated to raspberry pi's. With NTP they are essentially indistinguishable. I have something other than NTP in mind for the 6Tpi.

Bill,
That makes sense. Your GPS receivers are about 1000x more accurate than necessary. NTP lives in the millisecond to microsecond world, and GPS receivers in a nanosecond world.
