Hello gpsd-users and thank you for your patience with my first
post/question.
Problem:
gpsd is always staring in the foreground (-N) with no additional arguments.
Hardware:
beaglebone black
OS:
Debain wheezy image from beaglebone site with jessie sources. Full
upgrade/dist-update, and heavy package cleanout.
version:
3.10+dev1~a33bfd44-2
Repeatability:
always (6 different re-imagings of the bone and countless uninstalls and
reinstalls of gpsd)
Other cases:
Even with the stock Debain wheezy image, the installation of gpsd
(v3.6-4) acts the same.
More information:
Using the angstrom image that comes with the beaglebone black I was able
to successfully install and use gpsd. I could also use cgps do see the
data.
For both debian versions I have correctly set the config setting, using
db-reconfigure with wheezy and directly modifying /etc/default/gpsd in
jessie.
<code>
address@hidden:/var/log# cat /etc/default/gpsd
# Default settings for gpsd.
# Start the gpsd daemon automatically at boot time
START_DAEMON="true"
# Use USB hotplugging to add new USB devices automatically to the daemon
USBAUTO="true"
# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES="/dev/ttyO4"
# gpsd control socket location.
GPSD_SOCKET="/run/gpsd/gpsd.sock"
# Other options you want to pass to gpsd
GPSD_OPTIONS=""
</code>
The gps module (ls20031) is connected to UART4 on the bone. The tty is
setup correctly and I am always able to cat out the device and see the
NMEA messages.
If I actaully attempt to run gpsd in the foreground, such as gpsd -D8 -N
/dev/ttyO4 I get:
<code>
address@hidden:/var/log# gpsd -F /var/run/gpsd.sock -D8 -N /dev/ttyO4

</code>
with no further output.
I can see that even when gpsd is stopped there is something holding onto
the 2947 port:
<code>
address@hidden:/var/log# ps -ef | grep gpsd
root 1486 1090 0 21:05 pts/0 00:00:00 grep gpsd
address@hidden:/var/log# netstat -an | grep 2947
tcp 0 0 127.0.0.1:2947 0.0.0.0:* LISTEN
address@hidden:/var/log# lsof | grep gpsd
systemd 1 root 33u unix 0xde481a00 0t0
6652 /var/run/gpsd.sock
systemd 1 root 34u IPv4 6654 0t0
TCP localhost:gpsd (LISTEN)
</code>
This is what ps shows me every time I try to start gpsd:
<code>
address@hidden:/var/log# /etc/init.d/gpsd start
[ ok ] Starting gpsd (via systemctl): gpsd.service.
address@hidden:/var/log# ps -ef | grep gpsd
gpsd 1598 1 1 21:09 ? 00:00:00 /usr/sbin/gpsd -N
root 1618 1090 0 21:09 pts/0 00:00:00 grep gpsd

It looks like it is correctly reading in the config file and there are
no errors, hence my confusion.
I didn't see any suggestions for particular log outputs so if anything
else would be helpful please let me know.
Thanks,
