      你好,此问题应当在这个topic下已经回复了。
      http://forum.veye.cc/topic/50/插上树霉派-怎么弄都找不到video0设备/4

      另外github上已经增加了你说的这个版本的release的ko,是@tammojan 贡献的。 你可以直接尝试一下。

          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

                  @veye_xumm 2761619405673_.pic_hd.jpg 用你们提供的那些不用v4l2的API都可以,就是这个V4L2就用不了

                    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!

                              @tj It's happy to meet you here. Thanks again.
                              @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。
