Navio2 + Rpi 3 B with arducopter-quad selected
Kernel 4.4.36-a7765e7-emlid-v7+
emlidtool version 1.0.3

$ uname -a

Mavros nodes runs but no details was published in the topics: echo topic will post nothing.
so I did:

$ systemctl status ardupilot.service
● ardupilot.service - ArduPilot for Linux
Loaded: error (Reason: Invalid argument)
Active: inactive (dead)

My arducopter file w/ 192.168.15.100 is my IP for ground station:

Default settings for ArduPilot for Linux.

The file is sourced by systemd from arducopter.service

TELEM1="-A udp:192.168.15.100:14550"
#TELEM2="-C /dev/ttyAMA0"

Options to pass to ArduPilot

ARDUPILOT_OPTS="$TELEM1 $TELEM2"

Hello!

Could you please tell us more details? What exactly you’re trying to achieve?

You should use systemctl status arducopter to see if ArduCopter has been launched.

I read the docs again and I think the problem is that the instructions refer to ardupilot instead of arducopter, arduplane or ardurover.
Here:

Running ardupilot
Let’s run ArduPilot in another pane as stated in here pointing telemetry to 127.0.0.1:14650 by modifying /etc/default/ardupilot:

sudo nano /etc/default/ardupilot
modyfying

Then type:

pi@navio: ~ $ sudo systemctl start ardupilot
This command launches ArduPilot (one-shot. sudo systemctl enable ardupilot to make it persistent). You’ll see your LED blinking.

In case you make changes in ardupilot while it’s working, you should then restart:

pi@navio: ~ $ sudo systemctl restart ardupilot
Continue watching the tutorial for this step.

@schuermannsebastian

sudo systemctl start ardupilo

Thanks for the response. That worked. Thanks!

Sorry to bother again, it is not working again. This happened after I enabled raspberry pi camera as /dev/video0 using $ sudo modprobe bcm2835-v4l2 # to load it and create /dev/video0
then when I try running emlidtool or start arducopter it will not work.
