        @lll 信息太少,请提供更多信息。
        软件,硬件,连接方式,驱动安装后的检查。

            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?
