        请问有人回复吗?这里是出现video0了,但是打命令 dmesg | grep veye啥都没有,使用opencv去提取V4l2视频也是失败的,请问这怎么回事呢?

          1. cat /boot/config.txt 看看最下面有没有veye327相关的一行。
          2. ls /lib/modules/$(uname -r)/kernel/drivers/media/i2c/ 看看最下面一行有没有veye327驱动。
          3. 检查硬件连接,有没有给摄像头供电?
          4. 执行i2cdetect -y -r 10看看能否probe到0x3b地址,也就是显示出摄像头。
          5. 尝试wiki上的gstreamer命令。

              @luchec 你试试i2c0能看到吗
              i2cdetect -y -r 0
              另外硬件接好了吗?
              可否拍个连接细节图

                  感觉你可能装过几个型号,但是没有uninstall,去掉我标注的这两行试试。
                  另外试试i2cdetect -y -r 0

                      @luchec 验了一下,@tammojan 提供的这个release版本的确有点问题。 我会安排人跟进搞一下。需要几天时间,请关注github的更新。

                        @luchec (I'm tammojan.) I only tested the csimx307.ko , not the veye327. The CXIMX307 it seems to work for me. If there are problems with the drivers I'd be happy if you could find out!

                            @luchec 我已经上传了一个新版本,你可以尝试一下。注意gstreamer的预览命令,执行之前不要忘记了export DISPLAY=:0

                                  这个版本的linux是用的i2c-10,你正常使用preview和预览就可以了。
