      It feels strange, can you try veye_raspicam mode to make sure the camera is working properly?

      Remember to uninstall v4l2 driver, before you can use veye_raspicam mode.

          I think I have an idea.
          This is my kernel version.

          ~ $ uname -a
Linux raspberrypi 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33:35 GMT 2021 armv7l GNU/Linux

          So the driver I use is in 5.10.17-v7l+ dir.
          I think maybe you have an older version kernel.

          The earliest small amount of VEYE-MIPI-IMX327S has a small different with VEYE-MIPI-327E， It has a valid reset pin. So the driver is required to control the state of the pin. And I also implemented it in the new version of the driver.
          I soon realized that this was not compatible with the older version of the driver, so we removed the diodes that were told you in post earlier to maintain compatibility.

          Here are my suggestions, any one of which can achieve the goal of solving the problem:

          1. If it is convenient for you, you can remove the diode I pointed out to you in the previous post.
          2. Update your kernel, to use the 5.10.17 Murray v7l+ version of the driver.
          3. Based on the source code of the veye327 driver, recompile the driver for your current version of kernel.

            I am using the newest kernel version:
            pi@raspberrypi:~ $ uname -a
            Linux raspberrypi 5.10.17-v7l+ #1421 SMP Thu May 27 14:00:13 BST 2021 armv7l GNU/Linux

            Should I remove the diode?

              It seems that I was wrong, but I suggest you try the above advice.

                The diode was removed, the same thing.

                  Hi,After discussing with my colleagues, I think I found the cause of the problem this time.
                  Please read hdver, only if hdver > = 5 can you use the v4l2 mode of raspberry pi.

                  http://wiki.veye.cc/index.php/VEYE-MIPI-IMX327S_version_log

                  Because the V4L2 model and 327s products are relatively new, we discovered and solved this bug after a short period of time.
                  As an apology, I can give you a new 327S at half price. You can contact customer service on AliExpress or amazon.

                      I think that's the problem.

                        I recently ordered more modules VEYE-MIPI-IMX327S for AliExpress.

                        What date was this problem fixed?

                              Right. That's the result.
