    Hello ModalAI Team,

    I am working with VOXL2 / VOXL2 Mini and PMD ToF V2 (M0169), and I am facing an issue where the PMD ToF camera is not detected/started by voxl-camera-server.

    System details

    Platform: VOXL2

    System Image: 1.7.4

    PMD Module: M0169 (PMD ToF)

    Use case: Tracking + ToF + HiRes

    Hardware connection (Option 1)
    VOXL2 → M0076 → M0074 extender → M0169 (external regulated 5V supplied) → ToF

    External 5V is provided to M0169.

    Camera configuration

    Cameras enabled: PMD ToF + IMX214 (HiRes) + OV7251 (Tracking)

    IMX214 and OV7251 start correctly, but not pmd-tof

    kindly look at the screenshots.

      @Sarika-Sharma Now TOF is detected. I have choosed pmd-tof instead of pmd-tof-liow2.
      But please give solution for the following problem.
      When I used J7 according to the following configuration
      Hardware Setup
      M0104 Connector Interposer Sensor HW ID
      J7 M0135 JL Tracking (M0014 ) 2
      J7 M0135 JU Hires (M0025-2 ) 3
      OR
      J7 M0135 JL Hires (M0025-2 ) 2
      J7 M0135 JU Tracking (M0014 ) 3

      ONLY , The camera which is connected to JL is working either tracking or hires.
      Cameras connected to JU is not working.
      When i run voxl-camera-server it gives this
      WARNING: cam tracking (id 1) does not seem to be alive

      ------ voxl-camera-server: Started 1 of 2 cameras

      ------ voxl-camera-server: Camera server is now running
      OR
