    @Morten-Nissov ,

    Yes the old TOF (V1) is EOL and we only have the TOF V2 available now, but due to increase power requirements, the connector had to change. The Starling Front End board (M0173) provides the connector to plug in the M0178 tof assembly (look at https://docs.modalai.com/voxl2-coax-camera-bundles/ C26, or C27).

    The Starling camera front end is only compatible with VOXL2, not VOXL2 mini. However, if you just wanted to plug in TOF V2 directly into VOX2 Mini, we now have M0172, which you can find a pictured here : https://forum.modalai.com/topic/4125/indoor-navigation-using-4-depth-sensors . M0172 splits the VOXL2 dual camera connector into a TOF-compatible 40-pin molex connector and the uCoax connector for the cameras that use uCoax.

    We don't have M0172 officially available, but if you want to try it we can make it available in the shop. So you would need (M0172 adapter + MSU-M0178-1-01 (the whole TOF sensor assembly) ).

    The connection order would look like this:
    VOXL2 (mini) <-> M0172 <-> M0177 <-> M0178 <-> actual TOF sensor
    (everything to the right of M0172 is sold in this kit : https://www.modalai.com/products/m0178?variant=48528287793456)

    This would work for either VOXL2 or VOXL2 mini. The only down side i see is that M0177 is pretty short. I am not sure if we have an extension available, but will check.

    EDIT: Here is the extension that can go between M0172 and M0177 : https://www.modalai.com/products/msu-m0170

      Hi @Morten-Nissov ,

      Sorry for the delay. We will get the M0172 board available for purchase ASAP.

      Since your configuration uses M0014 camera, which would not be able to plug into M0172 splitter, here is your connection option:

      • VOXL2 Mini J6:
        • M0076 or M0135 interposer + M0014 camera
      • VOXL2 Mini J7:
        • M0172 interposer + TOF

      (You could swap the connections, such as TOF is connected to J6, and vice versa). You would simply need to update the sensormodules (camera drivers) used, according to the slot id of each camera.)

      When using VOXL2 mini with TOF, our guidance is to use only one TOF V2 per VOXL2 mini

      • the TOF V2 sensor uses 5V power input, however VOXL 2 Mini only has a budget of 900mA on the 5V rail because the input voltage to the mini is 3.8V and there is a step-up regulator to 5.0V. This is different from VOXL2, which uses an APM / ESC to supply 5V 6A into VOXL2.
      • the TOF V2 internally uses 3.3V and the pulsed current draw in different operating modes can be found here : https://docs.modalai.com/M0178/#irs2975-operating-modes . Using multiple TOF sensors on voxl2 mini can result in exceeding the current limit on the 5V regulator.

      Keep in mind that you will still be able to plug in additional cameras if you need to:

      • a uCoax camera plugged into M0172 (M0161, M0166, etc)
      • any camera that uses older connector plugged into M0135 (M0014, M0107, etc)

      One thing to keep in mind when using M0076 and M0135 is because they were originally designed for VOXL2, though compatible with VOXL2 mini, the interposers may interfere with the mini's mounting holes, because M0076 / M0135 (when inserted) have slight overlap with the mounting holes. However, the overlap may not be an issue if you dont have stand-offs on the side where M0076 / M0135 plugs into VOXL2 mini.

      We will update this thread once M0172 is available in the shop.

            Hi,

            We are trying to configure Voxl 2 Mini with the ToF sensor and a tracking camera with the , and we're having trouble with getting the ToF sensor to work. This is with the new ToF sensor and the new interposer you suggested for us to use.

            The cameras are attached in the following way:
            J7 <-> M0135 (JL) <-> M0014
            J6 <-> M0172 (J1L) <-> M0170 <-> tof
            The voxl suite we have on the board is: voxl-suite: 1.5.0

            To configure the cameras we run:
            voxl-configure-sku
            choosing options 23 (voxl-configure-sku) and 5 (pmd-tof ov7251 tracking).
            The output was the following:

            Your answers would construct the following SKU:
            
            family code:   MCCA-M0104 (voxl2-mini-board-only (MCCA-M0104))
            compute board: 6 (voxl2-mini)
            hw version:    1
            cam config:    05
            modem config:   ()
            tx config:      ()
            extras config:  ()
            SKU:           MCCA-M0104-C05-T0-M0-X0
            
            This sku will be saved to persistent memory so VOXL
            will remember what it is installed in, even between
            system image flashes.
            

            So we run: voxl-configure-mpa and reboot

            To inspect the cameras, we run voxl-inspect-cam -a , but we were able to see only the tracking camera:

            | Pipe Name |  bytes  | wide |  hgt |exp(ms)| gain | frame id |latency(ms)|  fps |  mbps  | format

            So we restarted the service voxl-camera-server , but we got the following error + warnings:

            Do you have any suggestions for how we can get this working?

              Note, we also tried to modify the preview resolution, as well as disabling the preview entirely. But making these changes to the /etc/modalai/voxl-camera-server.conf file didn't seem to change the actual configuration used, as reported when running voxl-camera-server in terminal.

              Do you have any suggestions for how we can get this working?

              Additional debugging:

              Moreover, we test some other configurations:

              • J7 <-> M0135 (JL) <-> M0014
              • J6 <-> M0172 (J1L) <-> M0170 <-> tof

              We copied the files: com.qti.sensormodule.ov7251_*.bin and com.qti.sensormodule.irs2975c_*.bin into the folder: /usr/lib/camera
              We used the command: camera-server-config-helper tracking:ov7251:0 tof:pmd-tof:2 giving the following output:

              And running voxl-inspect-cam -a still gives the following output:

              To be sure that all the parts were working, we tested two M0172 and 2 ToF sensors, which were actually working on VOXL 2. We also swapped the tracking camera and the ToF sensor (J6 <-> J7), copying the .bin files according to and adjusting the ID numbers.

                Additional debugging:

                Moreover, we test some other configurations:

                • J7 <-> M0135 (JL) <-> M0014
                • J6 <-> M0172 (J1L) <-> M0170 <-> tof

                We copied the files: com.qti.sensormodule.ov7251_*.bin and com.qti.sensormodule.irs2975c_*.bin into the folder: /usr/lib/camera
                We used the command: camera-server-config-helper tracking:ov7251:0 tof:pmd-tof:2 giving the following output:

                And running voxl-inspect-cam -a still gives the following output:

                | Pipe Name |  bytes  | wide |  hgt |exp(ms)| gain | frame id |latency(ms)|  fps |  mbps  | format

                To be sure that all the parts were working, we tested two M0172 and 2 ToF sensors, which were actually working on VOXL 2. We also swapped the tracking camera and the ToF sensor (J6 <-> J7), copying the .bin files according to and adjusting the ID numbers.

                @Morten-Nissov , please only put one sensormodule with the correct slot number in /usr/lib/camera. This will help eliminate any confusion.

                Also, does voxl-camera-server -l actually detect your TOF module?

                It seems your camera id is actually incorrect. It should be 1. The slot id is 2 (which is tied to the hardware), but the software camera Id is assigned as the cameras are probed in each slot. voxl-camera-server -l will tell you (at the top) which cameras have been detected, which slot and camera ids.

                  @Alex-Kushleyev Thanks for getting back to us so quickly.

                  We removed all the com.qti.sensormodule.ov7251_*.bin and the com.qti.sensormodule.irs2975c_*.bin files.
                  Then we ran, as you suggested, the command: voxl-camera-server -l. The output was:

                    @Alex-Kushleyev Thanks for getting back to us so quickly.

                    We removed all the com.qti.sensormodule.ov7251_*.bin and the com.qti.sensormodule.irs2975c_*.bin files.
                    Then we ran, as you suggested, the command: voxl-camera-server -l. The output was:

                    Just to make sure that only one camera was working, we ran: voxl-inspect-cam -a and got:

                    What do you think?

                        Hi, I'm Luca, and I'm currently working on the ModalAI voxl2 mini. Thanks for your help and your quick answers.

                        successfully wrote this camera config to disk:

                          Hi, I'm Luca, and I'm currently working on the ModalAI voxl2 mini. Thanks for your help and your quick answers.

                          To recap: I ran voxl-camera-server -l, and I got:

                          Instead of checking the Cam slot, I have to check Cam idx. So I ran the following command: camera-server-config-helper tracking:ov7251:0 tof:pmd-tof:1 and got the following output:

                          successfully wrote this camera config to disk:

                          @Luca-Zanatta , I believe your issue is that you are specifying the wrong type of TOF sensor. There are two types:

                          • pmd-tof (old, EOL)
                          • pmd-tof-liow2 (a.k.a irs2975c)

                          Based on your sensor id (Slave Address: 0x007A, Sensor Id: 0x2975), you have pmd-tof-liow2, so you should run camera-server-config-helper tracking:ov7251:0 tof:pmd-tof-liow2:1).

                          When you configured for pmd-tof, the camera server config was incorrectly set for the old TOF sensor, which has resolution of 224x1557. The new TOF sensor has resolution of 240x1629

                          Please try. Sorry i did not catch that earlier.

                              @Alex-Kushleyev @Luca-Zanatta I am also facing the same issue, can you please tell how to solve resolution problem.
                              I have tried to manually add preview width and preview height in vim /etc/modalai/voxl-camera-server.conf But when i run voxl-camera-server it still gives previous resolution 240*1557 and hence pmd-tof is not detected.

                                @Sarika-Sharma ,

                                The preview width and height parameters are always in the camera config file, so if you added them, they are duplicates (and will be ignored).

                                Please read through this thread as it has pretty detailed explanation how to configure the correct tof sensor (old or new) for a custom configuration.

                                Camera-server-config-helper is indeed helpful. If you use it correctly, you should not have to manually modify the resolution in the config file.

                                If you still cannot get this to work, please let me know what cameras you have plugged in (and which camera ports) on your voxl 2 mini.
