      $ md5sum tegra194-p2888-0001-p2822-0000.dtb

      你看一下你的/boot/veyecam下面的dtb是这个md5sum吗？

              你的驱动和dtb搞对了。
              现在i2c检测不到。请确认一下5V供电的连接，如果方便的话，最好用万用表量一下电压。
              另外就是确认一下FFC排线的安装方向。

                我现在能检测到摄像头了 请问怎么使用摄像头拍摄照片 另外我现在智能做到检测单个摄像头 如果想要接上6个的话 是不是要用12v的电源

                  可以参考这个链接：
                  https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_jetson/zh#.E5.AE.9E.E6.97.B6.E9.A2.84.E8.A7.88
                  用6个摄像头，差不多得6W+的最小功率，如果用额外的12V电源最好。

                      @lll 我调整了镜头位置 现在可以正常成像了 我再想问一下 如果想用代码调用要怎么操作 python或者c++都可以

                            摄像机支持外触发模式，用同一个外触发信号触发6个相机。
                            然后写程序从/dev/video0到/dev/video5取图。

                                          @lll 应该把J19上的备用短路子都拆下来。按照我的发给你的图操作。短路子可能少几个，你得再找几个或者用杜邦线短接一下J7的短路子。
