      I am having some issue with tracking camera. No matter what configuration I select It does not allow me to access the tracking camera.

      I cross checked all the connect on flight-deck. And connections looks fine

      yocto:/#  voxl-configure-cameras 3
attempting to use camera configuration 3
adding override_cam_id value=1 to /etc/snav/camera.downward.xml
adding override_cam_id value=2 to /etc/snav/camera.stereo.xml

yocto:/# cat /etc/modalai/camera_env.sh
export CAM_CONFIG_ID=3
export HIRES_CAM_ID=0
export TRACKING_CAM_ID=1
export STEREO_CAM_ID=2
export TOF_CAM_ID=-1

yocto:/#  voxl-image-streamer -c 2 -n 4 -i 192.168.100.90
STEREO camera selected.
using cam_id=2
Segmentation fault

      But for -c 1 it is opening stereo instead of tracking

      No matter what camera configuration I select I am just able to access hire and stereo even if I dont set voxl-configure-cameras 1

      yocto:/#  voxl-configure-cameras  

Which camera configuration are you using?
1 Tracking + Stereo (default)
2 Tracking Only
3 Hires + Stereo + Tracking
4 Hires + Tracking
5 TOF + Tracking
6 Hires + TOF + Tracking
7 TOF + Stereo + Tracking (not currently supported)
8 None

2
attempting to use camera configuration 2
adding override_cam_id value=0 to /etc/snav/camera.downward.xml
adding override_cam_id value=-1 to /etc/snav/camera.stereo.xml

      Even in the above situation where I have just set to tracking it still open Hires

      The same happens with voxl-cam-ros
      I am not able to access tracking cameras

        The camera configuration must match what is connected to the board. So if all 3 cameras are connected, that is the configuration you must use.

        Do not connect or disconnect cameras while the board is powered on

        Can you share a picture of how you have connected things? Are you sure the pin ones line up appropriately?

          Also, voxl-vision-px4 uses the tracking camera. So if it is running image streamer will need to be set as a slave as voxl-vision-px4 is the master
