      This happens with or without the portal. Other units seem OK and this unit was OK in a different environment. Trying to isolate the issue.

        camera server errors are very likely hardware related. usually a sensor is not fully plugged in

          Resurrecting this topic. We have two drones with identical hardware builds.
          Only camera's plugged in are tracking cameras to J4.
          Both are running the latest system image.

          Drone 1's camera server never crashes while flying Indoors/outdoors.
          Drone 2's camera server sometimes crashes and seems to be triggered by exposure changes when outside in bright environments. It is running a slightly newer version of voxl-camera-server.

          The failing drone has this in the logs from logcat | grep "camera":

          voxl:~$ logcat | grep camera

          They have not been crashed... and the failure happens regularly when in bright environments. I matched up software versions as well and the crash still happens, so it has to be some kind of hardware issue and the below can be disregarded.

          Hardware problems again with expansion or something weird in this specific camera/cable?

            These are usually hardware issues. Some possibilities

            1. crimped flex cable
            2. exposed copper on the flex cable
            3. loose or damaged connector
