    Yes, but when I try to run it I just get stuck at "Using configuration file ..."

    yocto:/$ voxl-streamer -c tracking
    Using configuration tracking
    Using configuration file /etc/modalai/voxl-streamer.conf
    

    And I've left it for almost 5 minutes with it stuck at this stage.

      Is voxl-camera-server running? You can check with

      voxl-inspect-services

        It is enabled but not running, so how would I go about running it?

        yocto:/$ voxl-inspect-services
         Service Name        |  Enabled  |   Running   |  CPU Usage
        --------------------------------------------------------------

         docker-daemon       | Disabled  | Not Running | Not Running
         modallink-relink    | Disabled  | Not Running | Not Running
         voxl-camera-server  |  Enabled  | Not Running | Not Running

          You can run it with:

          systemctl start voxl-camera-server
          

          If it is enabled but not running though that means that it crashed on startup (or you stopped it). If you didn't manually stop it that means it encountered an error which is usually due to a bad camera connector causing the driver to throw an error. If you start it and it still shows up as stopped afterwards could you run it manually with:

          voxl-camera-server -d 0
          

          and paste the output here

            I do have the J3 and J2 ports using the MIPI extension cables if that might be causing problems

              You have all of the cameras indicated there plugged in (hires, stereo, tracking)?

                Yes, and I've double checked that they are all in the correct ports

                  It's also possible that your extension cables are plugged in backwards, 90% of that output is reading the config file at /etc/modalai/voxl-camera-server.conf. The critical part is the

                  ----------- Number of cameras: 0
                  

                  This is the response from the driver when we asked how many cameras it sees, it will often refuse to open any of them if any of the lines are incorrect, could you show a picture of you cable setup?

                    There could also be a break in one of the cable lines (they can bend gently but should not be folded to an angle)

                      Sorry for the late response, I've been doing some testing. so I've narrowed it down to the error lying in the stereo cameras, I connected each sensor one at a time, reconfigured, and ran the voxl-streamer and was able to get footage for the hires and tracking, but when it came to the stereo it would not work. When I would reboot the system and inspect the services I would see that the voxl-camera-server is running, but once I tried to voxl-streamer -c stereo it would get stuck at the same place and the voxl-camera-server would stop running. I've confirmed that both of my extension cables are working by testing them with the hires camera. I checked the physcial connections on the stereo cameras and there are no creases in them, they look just as they were folded with the original setup, and I believe that if any of the connections were inverted then the VOXL wouldn't even start up.
