      I am trying to connect an IMX412 and an AR0144 to the VOXL2 with a M0084 cable on J7. Below is the custom configuration file I created. The issue I'm encountering is that neither sensor is being identified on J7U when I run 'voxl-camera-server -l'. Is there a hardware constraint regarding these cameras that I am not aware of?

      J6_LOWER_SENSOR="pmd-tof-liow2"
      J6_LOWER_NAME="tof-rear"
      J6_LOWER_ROTATE="false"

      J6_UPPER_SENSOR=""
      J6_UPPER_NAME=""
      J6_UPPER_ROTATE="false"

      J7_LOWER_SENSOR="imx412"
      J7_LOWER_NAME="imx412_sensor_front"
      J7_LOWER_ROTATE="false"

      J7_UPPER_SENSOR="ar0144"
      J7_UPPER_NAME="ar0144_sensor_down"
      J7_UPPER_ROTATE="false"

      J8_LOWER_SENSOR="pmd-tof-liow2"
      J8_LOWER_NAME="tof_front"
      J8_LOWER_ROTATE="false"

      J8_UPPER_SENSOR=""
      J8_UPPER_NAME=""
      J8_UPPER_ROTATE="false"

          @QSL , are you using kernel variant 0 or 1?

          you can check using voxl-version, whether you see mach var 1.0.0 or 1.0.1.

          1.0.1 kernel is used with M0173 Starling Camera Front End due to I/O pin configuration specific to M0173.

          If you are not using M0173, for example when you use M0084 connected to VOXL2 J7, you need to switch to kernel variant 0. by either re-installing the VOXL2 SDK or relfashing the correct kernel from the SDK.

          cd voxl2_SDK_<voxl-sdk-version>/system-image
          adb reboot bootloader
          
          #flash variant 0
          fastboot flash boot_a m0054-1-var00.0-kernel.img
          fastboot flash boot_b m0054-1-var00.0-kernel.img
          
          #or flash variant 1
          fastboot flash boot_a m0054-1-var00.1-kernel.img
          fastboot flash boot_b m0054-1-var00.1-kernel.img
          
          #reboot
          fastboot reboot
