Re: [time-nuts] beaglebone black, debian, NTP client

That's one thing that annoys me with those graphs. If you average jitter it loses its meaning. What you then get is the mean deviation (aka offset). Without an accompanying standard deviation (and a test that you actually have a gausian distribution) this value is not worth much. What I am

Re: [time-nuts] beaglebone black, debian, NTP client

A couple of people have. If you look at the archives you'll find a few of those. Dan Drown sticks out a bit here, as he is AFAIK the only one who used a GPIO as a PPS input on the BBB: (last mail seen around december 2014) http://blog.dan.drown.org/beaglebone-black-timer-capture-driver/

Re: [time-nuts] beaglebone black, debian, NTP client

Has anyone fooled with using NTP on a beaglebone black running Debian (the beagleboard.org image)? I assume it's just a matter of turning on ntpd (which I'm not sure is even installed) and/or running ntpdate (I'm not looking for super accuracy.. it's for a sprinkler timer)

Re: [time-nuts] beaglebone black, debian, NTP client

The Debian 8.x (jessie) releases for the BeagleBone run systemd-timesyncd, which is installed and on by default. As long as the Beaglebone is hooked to the internet, it has correct time to +/- 10 milliseconds or so. Probably good enough for a time-nut lawn sprinkler. systemd-timesyncd is a

Has anyone fooled with using NTP on a beaglebone black running Debian (the beagleboard.org image)? I assume it's just a matter of turning on ntpd (which I'm not sure is even installed) and/or running ntpdate (I'm not looking for super accuracy.. it's for a sprinkler timer)
