      根据这个地方的说明,接触面向外,所以你排线插到摄像头的那一头,方向插反了。

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

                          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
