    @Judoor-0 , have you used the TOF sensor recently for extended periods of time (before upgrading to SDK 1.2.0 ?). Extended, i mean, longer than just a few minutes.

    I am just trying to figure out whether this is an old hardware problem or a new software problem (or potentially new hardware problem).

    Also, what adapter do you use to plug the TOF sensor into VOXL2 board (the first adapter that plugs into VOXL2). Is it M0076 or M0135 or something else?

    @Alex-Kushleyev I really need this sensor to work so can you tell me if you think that it is a hardware problem I need to change the faulty piece as quick as possible. I'm right now making a new order for another starling 2 so I need to know.
    Otherwise, what can I do to debug this sensor.

      @Judoor-0 , I am sorry that this happened to you.

      It seems that there is some hardware issue.

      Let's do a quick test by connecting TOF to a different camera port and updating camera server configuration to reflect this:

      • i am assuming your 3 cameras (tof, hires, tracking) are connected in the following configuration : https://docs.modalai.com/voxl2-camera-configs/#c-06-tof-hires-and-tracking-d0005-starling
      • this means TOF should be in slot 0, IMX214 in slot 2, ov7251 (tracking) in slot 3. the last two i can see confirmed from the log that you posted (where TOF was not detected).
      • power off voxl2
      • remove the flex cable witih IMX214 and tracking camera from J7
      • disconnect M0135 + TOF from J6 and plug it into J7 (same orientation as it was plugged into J6)
      • power on voxl2
      • copy the TOF driver for slot 2: /usr/share/modalai/chi-cdk/irs1645/com.qti.sensormodule.irs1645_2.bin
      • run voxl-camera-server -l to see if TOF is detected in slot 2
      • edit /etc/voxl-camera-server.conf to disable hires and tracking cameras (enabled : false), confirm that TOF camera ID is set to 0 and TOF is enabled in the config file
      • start voxl-camera-server in foreground and see if TOF is functioning normally.

      Please let me know the result.

        @Alex-Kushleyev Here is my starling 2 camera configuration the only difference is that I also have a M0135 module to connect the imx214 and tracking.
        PXL_20240522_074642441.MP.jpg
        So, I unpluged the cameras, plug the TOF sensor on the other M0135 adapter.
        I copied the driver in /usr/lib/camera and delete the existing one for slot 2 (it was imx214)
        Now when I run voxl-camera-server -l I got this, so I suppose it correctly detected the TOF sensor.

        Then when I disable the other cam and start the voxl-camera-server, I still got this with voxl-inspect-cam -a

        And I've got the same errors when I directly run voxl-camera-server, the command end up by aborted and nothing's working.

          @Judoor-0 , since the issue is the same when using voxl2 J7, it seems there may be a hw issue either in the m0135 adapter or the tof module. If you are able, please try the second m0135 adapter (disconnect from the hires and tracking cameras and connect to tof), then plug back into j7. If the symptoms repeat, the TOF sensor is most likely bad, so we can send a replacement one to you.

            @Alex-Kushleyev I tried with both and it didn't work either.
            Please, if you can send a replacement one as soon as possible it would be great because my schedule to deliver the finish product is very tight.

              @Alex-Kushleyev Also why does it says that the resolution for the camera should be 224x1557 and not 224x171 like on the datasheet of the sensor?

                @Judoor-0 , the tof sensor takes multiple exposures and returns stacked IR image (kind of like HDR). That image is processed by the TOF library on the cpu to output the final image at the proper resolution.

                I will check about RMA, you probably need to fill out the form: https://www.modalai.com/pages/rma

                  @Alex-Kushleyev Ok, I filled up the RMA form in cas it's needed.
                  My S/N is M23000001E9.

                    @Judoor-0 I'm facing a similar problem with ToF configuration on a Starling setup. Through RMA was anything wrt. to hardware found? If not how did RMA help you?

                      @Jetson-Nano , if you run the camera server in foreground (and with -d 0 option to enable debugging), it could help localize the issue. Also try disabling cameras one by one in voxl-camera-server.conf to find which camera is causing an issue.

                      Is the issue you are seeing specific to TOF? Was it previously working?

                        @Alex-Kushleyev I tried that and have posted the output here (https://forum.modalai.com/topic/3688/vision-sensors-not-detected-in-voxl2). Initially the issue was with all the cameras, now it is only ToF.

                          @Jetson-Nano , OK it seems we have two parallel threads going. please see my reply to the other thread https://forum.modalai.com/topic/3688/vision-sensors-not-detected-in-voxl2 and test it step by step as I suggested (reducing fps of imx214 camera first, then disabling sensors one by one)
