      下载官方驱动，移植官方设备树后，可以看到video0到video7.但是所有video都是无法打开，cannot open错误。
      修改驱动以后，可以正常打开，正常出图。

      原驱动中veyecam2m_g_bus_config（）函数是屏蔽的，释放以后，并增加pad-id参数，type改为V4L2——MBUS——CSI2_DPHY，即可正常使用。
      同时906行的.get_mbus_config也要释放掉，之前也是注释掉的。
      调试了很久，最终通过修改驱动方式解决了。
      原驱动还少一个break编译无法通过。
      希望别人少走我的弯路。

        @乔康 感谢你的分享。
        这个问题应该还是跟kernel版本有关系。我们开始调的3588的kernel版本不需要veyecam2m_g_bus_config功能。
        总是，驱动调试你们很棒了~👍

          @veye_xumm 您好。
          同一块板卡，同样的设备树和摄像头驱动，之前使用的是5.10.66和5.10.106的内核。均推流正常。换成5.10.226的内核后，推流时遇到报错如下。
          root@ema:/home/ema# Setting pipeline to PAUSED ...
          error: XDG_RUNTIME_DIR not set in the environment.

          摄像头驱动与设备树详见附件。驱动已经正常启动。

          请问驱动需要相应升级吗？报错能看出什么问题吗？

            这个问题我们没有遇到。
            你可以试试直接用v4l2-ctl抓图，看看效果如何？
