    @brianaustin

    I found the cable in your link on the website. It was under the cables section and not the image sensor section. Would the dual sensor board not be valid for this setup?

    @brianaustin, M0135 should work for this application. I just thought you were using a different Y flex cable plugged into J7.

    Also, it does look like you have the cameras plugged in correctly.

    Please follow my suggestion in previous post and swap ov7251 and imx214 places (taking note of pin 1 orientations) and see if ov7251 can be successfully probed in slot 3 and imx214 in slot 2.

      the portal only shows Mulit-View but there are no streams shown and only a checkbox that I can select but no images. The Stereo Sensor does not work now either

        @brianaustin , thank you for running the test. The results are not conclusive. Let's try one more thing.

        • Please list sensormodule files of /usr/lib/camera right now, just to double check:
        ls /usr/lib/camera/*sensormodule*
        

        at this point you should have the following, which will support either configuration of ov7251 and imx214 (either slot 2 or 3). It is OK that there are more sensormodule files than cameras - for the ones that are not valid for the given configuration, the camera pipeline will try to probe the camera, will not find it, and will move on to the next sensormodlue.

        com.qti.sensormodule.imx214_2.bin
        com.qti.sensormodule.imx214_3.bin
        com.qti.sensormodule.ov7251_2.bin
        com.qti.sensormodule.ov7251_3.bin
        com.qti.sensormodule.ov7251_combo_0.bin
        com.qti.sensormodule.ov7251_combo_1.bin
        
        • disconnect OV7251 completely and test camera scan again (double check IMX214 is plugged in correctly, with flex cable pointing towards the center of the M0135 board). please let me know if IMX214 is detected
        • keep OV7251 disconnected and plug IMX214 back into slot 3 and do the scan again to make sure IMX214 is detected in the slot 3, which was working before.

        If you have another M0135 or ov7251 (fisheye) to try, you could do that to help figure what is not working properly, M0135 or the ov7251 camera.

            @brianaustin ,

            Thanks for running those tests. Since plugging in IMX214 into slot 2 (J7L) did not result in successful detection of the camera, it is likely that M0135 adapter is faulty.

            However, since IMX214 does work in slot 3 (J7U), my expectation was that ov7251 would work in slot 3 as well, but that was not the case.

            Another thing to try is to see if the single OV7251 camera can be detected in slot 0:

            • unplug the stereo flex from J6 and just leave the small interposer M0076 in J6
            • connect the single tracking camera ov7251 where the stereo pair was connected. Note that when tracking ov7251 is correctly plugged into VOXL2 J6 via M0076, the tracking camera flex will point away from the voxl2 board, see image below
            • you dont need to change any sensormodules because you already had the stereo set up and for detection purposes, the combo driver for ov7251 will be able to detect the camera.
            • since we know that M0076 is working (stereo is working), this test will tell us if the tracking ov7251 is working or not.

                Looks like I need to get a new dual connector or the other cable yeah?

                @brianaustin , great!

                Now, one more test 🙂

                Take the M0076 with the tracking OV7251 from J6 and plug into J7. You already have the sensormodule for slot 2 in place for J7L, so detection should work. Hopefully this works and this would confirm that J7L camera path is working.

                BTW you should be able to actually test the feed from the camera using the M0076 connection to J6 and J7 (just turn off other cameras in config, or maybe even leaving them enabled will work because camera server will just skip the undetected cameras).

                Then you would need a new M0135 interposer (you can submit RMA request at https://www.modalai.com/rma)

                    @brianaustin , YES!

                    Please submit and RMA form to request a replacement M0135 board. If you need a replacement more urgently, you way want to buy another M0135 and you will have another one as a back up (and future expansion).

                      Received the new connector and everything now works! All cameras are operational and looking fantastic.

                      Thank you!
