I suppose you could do that by omitting the device parameter from gpsd
command line. Try *gpsd -D 5 -n -N /dev/ttyO4* , and comment out the *
refclock PPS* */dev/pps0 lock NMEA* line from chrony configuration file
before restarting chrony.

Thank you Jaka that helps me a lot.
But I have right now a diffrent problem. I am trying to make a NTP server.
I am using PocketBeagle and GPS module - UART GPS NEO-7M-C .
I have connected it like that:
PB_UART4-Tx(P2.07)- GPS NEO-7M-C Rx
PB_UART4-Rx(P2.05) - GPS NEO-7M-C Tx
After runni
To Jack,
you cannot run gpsd separately because operating system is trying to run it
as a service process. It fails, but the process still seems to be "running"
in some way.
Stop it first with service gpsd stop, then you should be able to run gpsd
from userspace normally.

Hello,
I am trying to run NTP server on my PocketBeagle with GPS and PPS time
source. To establish that I am following your notes.
However when I try to run gpsd it is giving me output like this:
:$ gpsd -D 5 -n -N /dev/ttyO4 /dev/pps0
gpsd:INFO: launching (Version 3.17)
gpsd:IO: opening IPv4 s
Hi,
I have gps with pps and signal level is measured in scope and is ok. The
problem is that when ppstest command is run the pps output is displayed as ok
but after arround 180 to 230 seconds i get error connection timed out error. I
have gpsd amd chrony installed.
Strangely when i restart gpsd
First off, Thanks Robert for all your help. Looks like we are up and
running!
Next, I wanted to post a few notes in case others run into the issues that
I had.
1) From a clean install, apt-get update then apt-get upgrade
2) git clone https://github.com/beagleboard/bb.org-overlays.git
3) cd b
Perfect! That seems to have fixed my issues! Ill be sure to add a post on the
web describing the procedures we went through to help others!
I do have one other question for you. If this is out of scope, Ill ask it on
another forum, but I figured I would start here...
Now I have confirmed tha
Robert,

I have re-imaged my BBB and made the correction to the typo in my overlay file.
However, it appears as if I am having the same issue. When I install the
overlay in the uEnv.txt file and reboot, I am never able to ssh back into the
BBB.
My file is below for your review. I can't seem to find

Robert,
Your help is much appreciated! Making progress I think... Well, kind of...
So I attempted to replace target = <&ocp>; with target = "/" (when it should
have been target-path)
I didnt notice the typo and applied the overlay in uEnv.txt and rebooted. Now,

Hi Robert,
So I was able to get the file compiled. Basically, I pulled down your
bb.org-overlays project from github, then added my custom dbs file to the
/src/arm directory and finally ran ./install.sh This seemed to compile
and install the new dtbo in the /lib/firmware directory.
Next, I m
Robert,
Thank you again for your assistance. I am stuck trying to get the overlay to
compile and am assuming that I have something incorrect. Below is the overlay
that I created:

* Virtual cape for UART1 on connector pins P9.24 P9.26

Robert,
Thank you for the fast reply.
So I assume that I need to edit your lines:
P2_01_pinmux { status = "disabled"; }; /* gpio1_18 - EXTINT */
P2_03_pinmux { status = "disabled"; }; /* gpio0_23 - PULSE */

Hello,
My goal is to make an ultra-precise clock on the beaglebone black by using
the 1 pps signal from my adafruit GPS. I have been readying about the
device overlays / capes but there seems to be a lot of outdated information
out there that is very confusing.
My 1 pps is connected to P9_12
