      I am trying to use the module for guiding in astrophotography (Astroarch system on an rpi5), and there is an indi-v4l2 driver that recognizes the camera but can only play the video stream, not take singe exposures or control exposure and gain via v4l2. Being able to use the standard v4l2 controls would be ideal.

      I managed to install the veyecam2m driver and get video on dev/video0, but when i try v4l2-ctl -d /dev/video0 -l I get nothing back, no controls available for this device.
      I also tried the i2c_cmd method, built the read and write from source, and when i call for camera_i2c_config i get

      ~/raspberrypi/i2c_cmd/bin (master*) » ./camera_i2c_config
      setting GPIO for board revsion: d04170
      Failed: don't know how to set GPIO for this board! Type is 17
      Use i2c-10 for the sensor (-y 10)

      when i try veye_mipi_i2c.sh commands the answers are all wrong:

      ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f devid
      device id is 0xff

      ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f boardmodel
      Board model is VEYE-MIPI-327

      ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -w -f cameramode -p1 0x1
      w cameramode is 0x 1

      here i thought i had set it to manual mode, but no:

      ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -y 10 -r -f cameramode
      r cameramode is 0xff

      Can u shed some light? Thank you!

        @brunosaisi said in veye-mipi-IMX462 on rpi5 get video stream but cant controll via v4l2 or i2c:
        I also tried v4l2-ctl -d /dev/v4l-subdev2 -l

        and get:

          For configuring this camera via I2C, the process is not done through v4l2-ctl but directly using a script. Please note the following regarding this script:

          1. If you are using the v4l2 driver mode, camera_i2c_config is not required.
          2. When running ./veye_mipi_i2c.sh, make sure to specify the I2C bus you are using with the -b parameter.

          Below is an explanation regarding the I2C bus.
          https://wiki.veye.cc/index.php/I2c_bus_number_and_video_node
          For long exposure usage, you may need to configure the lowlight function or the new_mshutter function. Please refer to the corresponding section in the link below.

            @veye_xumm the -b parameter makes no difference, i tried all the possible bus numbers and still get all the wrong answers. for example:

            ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -b 11 -r -f hdver
            hardware version is 0xff
            release date is 20ff-ff-ff

            I was able to set new expmode to manual:
            ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f new_expmode
            r new expmode is manual, use new_mshutter and new_mgain

            But when i try to set the new_mshutter i get:
            ~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -b 10 -w -f new_mshutter -p1 1000

            awk: cmd. line:1: (FILENAME=- FNR=1) fatal: division by zero attempted
            ./veye_mipi_i2c.sh: line 1290: [: -gt: unary operator expected
            ./veye_mipi_i2c.sh: line 1294: >>8: arithmetic syntax error: operand expected (error token is ">>8")

              Please show me the result of this:

              dmesg | grep veye

              This can reveal which specific I2C bus your camera is on.
