      I appreciate your prompt and helpful response. I successfully copied the dtbs file from "dtbs/Orin/JetPack_5.1.2_Linux_JETSON_ORIN_TARGETS/dts dtb/VEYE-MIPI-CAM2M" path, and everything is functioning properly.

      However, I am currently facing a second issue related to camera controls. I am attempting to manage exposure and gain, but when I use the v4l2-ctl command to list the camera controls, I cannot locate the settings for exposure and gain. Is there an alternative method to control exposure and gain that you could recommend?
      The v4l2-ctl --all result:

        Because our camera has many features beyond the standard V4L2 controls, we provide scripts that allow parameter configuration by directly writing to I2C registers.

        Please refer to part4.3

          Thank you for your prompt response.
          I'm currently facing two issues while using the I2C script to set parameters from the specified path: nvidia_jetson_veye_bsp/i2c_cmd/bin/veye_mipi_i2c.sh .

          1- Firstly, the document link provided (https://wiki.veye.cc/index.php/I2c_bus_number_and_video_node) does not specify the appropriate -b parameter for Orin Nano. To identify the correct bus number, I executed the following command:
          ls -ltrh /sys/bus/i2c/devices/i2c*
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-2 -> ../../../devices/platform/3180000.i2c/i2c-2
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-9 -> ../../../devices/platform/3180000.i2c/i2c-2/i2c-9
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-8 -> ../../../devices/platform/31e0000.i2c/i2c-8
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-7 -> ../../../devices/platform/c250000.i2c/i2c-7
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-6 -> ../../../devices/platform/31c0000.i2c/i2c-6
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-5 -> ../../../devices/platform/31b0000.i2c/i2c-5
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-4 -> ../../../devices/platform/bpmp/bpmp:i2c/i2c-4
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-3 -> ../../../devices/platform/3190000.i2c/i2c-3
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-10 -> ../../../devices/platform/3180000.i2c/i2c-2/i2c-10
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-1 -> ../../../devices/platform/c240000.i2c/i2c-1
          lrwxrwxrwx 1 root root 0 Mar 15 2023 /sys/bus/i2c/devices/i2c-0 -> ../../../devices/platform/3160000.i2c/i2c-0
          lrwxrwxrwx 1 root root 0 Dec 19 05:26 /sys/bus/i2c/devices/i2c-11 -> ../../../devices/platform/13800000.display/i2c-11
          Can you assist me in determining the appropriate -b parameter based on this information?

          2- Secondly, although I can successfully read parameters, I encounter difficulties when attempting to set them. For instance:
          ./veye_mipi_i2c.sh -r -f mshutter
          r mshutter is 0x1
          ./veye_mipi_i2c.sh -w -f mshutter -p1 0x44
          w mshutter is 0x44
          ./veye_mipi_i2c.sh -r -f mshutter
          r mshutter is 0x1
          It appears that the parameter is not being set successfully, as reading it after the supposed update returns the default value. Could you guide me on where I might be going wrong in the parameter-setting process?
          I appreciate your assistance in advance.

              Thank you for your online response.
              What about my second question. Have I do something wrong that the values of parameters do not set?
              ./veye_mipi_i2c.sh -b 9 -r -f mshutter
              r mshutter is 0x 1
              ./veye_mipi_i2c.sh -b 9 -w -f mshutter -p1 0x44
              w mshutter is 0x44
              ./veye_mipi_i2c.sh -b 9 -r -f mshutter
              r mshutter is 0x 1
              It have the fix value every time i get it!

              Thank you for your ongoing support

                To confirm your I2C bus, please enter the following two commands and send the results back to me.

                ./veye_mipi_i2c.sh -r -f hdver -b 9

                ./veye_mipi_i2c.sh -r -f hdver -b 10

                  @veye_xumm

                  The results:

                  ./veye_mipi_i2c.sh -r -f hdver -b 9
                  hardware version is 0x 1
                  release date is 20 1- 1- 1

                  ./veye_mipi_i2c.sh -r -f hdver -b 10
                  hardware version is 0x 7
                  release date is 20 0- 0- 0

                    @joe said in VEYE-imx462 and Orin Nano developer kit problem:

                    ./veye_mipi_i2c.sh -r -f hdver -b 10
                    hardware version is 0x 7

                    So your camera is connecting to i2c bus 10.

                    Please use -b 10 as parameter for ./veye_mipi_i2c.sh

                      It seems that the parameters I've configured are retaining their previous values:

                      ./veye_mipi_i2c.sh -b 10 -r -f mshutter
                      r mshutter is 0x 0
                      ./veye_mipi_i2c.sh -b 10 -w -f mshutter -p1 0x44
                      w mshutter is 0x44
                      ./veye_mipi_i2c.sh -b 10 -r -f mshutter
                      r mshutter is 0x 0

                      or

                      ./veye_mipi_i2c.sh -b 10 -r -f mirrormode
                      r mirrormode is 0x 0
                      ./veye_mipi_i2c.sh -b 10 -w -f mirrormode -p1 0x02
                      w mirrormode is 0x 2
                      ./veye_mipi_i2c.sh -b 10 -r -f mirrormode
                      r mirrormode is 0x 0

                      Am I making a mistake somewhere?

                        @joe Please try putting -b 10 at the end of the command.

                          I noticed that there is no difference when I change the order of '-b 10' to the end of the line in the command. I'm running the command from ~/nvidia_jetson_veye_bsp/i2c_cmd/bin; can you confirm if this path is correct? Additionally, I'm open to any alternative solutions or suggestions. Thanks in advance for your help!

                            From this point, your program reads hdver correctly.

                            However, based on the feedback from all your other scripts, it seems that both reading and writing cannot be executed properly.

                            Here are the commands and displays from my side. The difference is that the camera is connected to i2c-9.

                            How about you try recompiling i2c_read and i2c_write?

                                It is indicated in the documents about "New function list" that:
                                "The following new features are only supported in camera's firmware versions with release time later than 2022-11-22."
                                My firmware version is exactly 2022-11-22. Is this version support "New function list"?
