    Hi:

    Could you please list the content of your /data/misc/camera directory? I am wondering if the process of generating that file was interrupted and now it doesn't attempt to generate it anymore.

    If there is anything in the /data/misc/camera directory I would move it to another temp directory - say /data/misc/camera/temp and try running the app again.

    Also as a quick experiment, I would put in just the TOF camera, remove other cameras and run the app again to see if it helps.

    @hitendra Thanks for the suggestions.
    Here is the list of file present in data/misc/camera directory
    camera'.png
    each of these files are just have these of 0 bytes each

    default installed voxl_hal3_tof package gives error as resolution not supported. And changing the resolution from the source as we did mentioned earlier does run the package but than stops at irs10x0c_lens.cal file being missing
    tof_error_2.png
    after changing the resolution and compiling again
    tof_erro3.png
    and hence topics are created but they don't publish any data

      That lens cal file is created the first time the driver is launched, it does take about 20 seconds to generate. Changing the resolution in the code probably is just covering up the fact the TOF camera isn't launching.

      The CAM_ID changes based on which sensors are plugged in due to a quirk in the Qualcomm camera subsystem. It's most likely the wrong CAM_ID is being assigned to TOF in the config. Maybe a camera is/was unplugged?

          You're selecting TOF+Tracking, but there is no tracking sensor installed. So the TOF_CAM_ID is probably coming out incorrect.

          Do you have a tracking camera? If so, please power off and install
          If not, can you please try export TOF_CAM_ID=1 ?

          thanks!

            @Chad-Sweet
            we installed tracking camera and reconfigured voxl using voxl-configure-camera

            and tracking camera is working
            Screenshot from 2021-01-13 11-23-59.png

            than we tried to run tof package again but still the problem persist. we even tried to change the TOF_CAM_ID but still no change.

              OK, good the tracking sensor is working. Sorry about this, the tof setup is still in beta. We clearly need to document the setup way better.

              Can you please print which version of system image you are using (voxl-version)? The error implies an older system image which does not support that hal3_tof_cam_ros.

              ERROR: Libcamera sending post-processed TOF data. App does NOT get RAW16 TOF camera data

              The error above implies an older version of libcamera which would use tof_cam_ros instead

              Just FYI, the TOF_CAM_ID needs to match what is in the launch file. This message shows what is in the launch file:
              /tof/voxl_hal3_tof_cam_ros_node/camera_id: 0

                        Assuming the ipk is installed, can you please then run this command and then try the ROS node again?

                              OK, good progress. That should be working. Can you give it a full power cycle and see if it says up?

                                  Unplug power from the VOXL and plug it back in. Then try the test over. You look like you're in a working state.

                                      It is the way for software to tell which TOF driver should be used. Setting to 1 supports the HAL3 method you are using, setting to 0 supports the older libCamera method using tof_cam_ros

                                      The HAL3 method is intended to give the developer more control over the pipeline

                                          Hi @gauravshukla914 ,

                                          Thanks for the help with this. We've released a new beta version of the voxl-hal3-tof-cam-ros that supports auto detection of ToF and defaults the persist.camera.modalai.tof setting properly.

                                          It will be in out next voxl-suite release, but is available from our dev channel here if you are interested in using this link

                                          The updated readme is here.

                                          Thanks!
