              这个链接，part3.7。
              检查一下dtb和驱动的安装是否正确。

                      @lll 不是ko，是dtb。你dtb用错了。

                        我用的是这个 这个是从你们提供的jetpack_5.1_linux_jetson_agx_xavier_targets里面的mv-mipi-cam的

                          从你系统的状态来看，误用了CS-MIPI-SC132目录下的，应该用MV-MIPI-CAM目录下的。

                            @veye_xumm 我是直接将mvcam下的dtb复制到相应的系统文件夹下的

                              @lll 应该是弄错了，你可以用md5码确认一下。

                                $ md5sum tegra194-p2888-0001-p2822-0000.dtb
                                304204131057b7d998aa15e9733e78bf 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。
