    I got new VOXL Flight Deck.
    But it seems imu0 is not detected.
    voxl-imu-server.conf is default.
    Do I need to do any configuration to use IMU0?

    / # voxl-list-pipes | grep "imu"
    imu1
    
    / # journalctl -u voxl-imu-server

      Do you mind sharing the output of voxl-imu-server --test and voxl-version thanks!

      VIO can be configured to use either IMU, to select IMU1 just run voxl-configure-qvio and select IMU1 when prompted which to use.

        Yes, VIO works if I select IMU1 (default is IMU0).
        I flashed system image to 3.6.0 (preserve the /data/ parition).
        I didn't confirm whether IMU0 was working at 3.3.0.
        If necessary, I can re-install 3.3.0 and check again.

          @James-Strawson Could you please check the outputs?
          I want to know whether this is hardware issue or configuration issue.

            I flashed system image v3.3.0.
            But imu0 still doesn't work.

              Hello,
              When I upgrade to v3.8, voxl-imu-server no longer starts.
              I think imu0 is not available, it is an initial defect.

                Hello,
                When I upgrade to v3.8, voxl-imu-server no longer starts.
                I think imu0 is not available, it is an initial defect.

                  @stevedan Couldn't find the way to solve so we sent back to ModalAI with RMA.
                  I wonder what was the issue of this.

                    @stevedan Couldn't find the way to solve so we sent back to ModalAI with RMA.
                    I wonder what was the issue of this.

                    @JP-Drone In my case, I was using the rb5 so the correct service was voxl-px4-imu-server, which was already running. The qvio, vison-px4 takes imu from imu_px4 not imu0. This is specific for the rb5.
