      @veye_xumm 我用gstreamer测试了一下,但是画面全是绿色且过一会就断了。测试指令是:gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY, width=(int)2464, height=(int)2056" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)I420" ! nv3dsink sync=false

        这个型号升级之后不支持uyvy了,你可以参考这个地方的备注。

        你可以试一下直接使用qv4l2连接图像。

            @lakers 你拍一下照片发给我看看。主要是供电和fpc线的接触面状况。

                  @lakers 硬件连接看起来没毛病。
                  可能是之前你的尝试把数据格式换了。
                  你用脚本,把摄像头恢复一下默认值
                  https://wiki.veye.cc/index.php/Mv_mipi_i2c.sh_user_guide#factoryparam

                  ./mv_mipi_i2c.sh -w -f factoryparam -b 10
                  

                  然后重启主板。
                  然后再尝试一下qv4l2。

                    @veye_xumm 我按照您的方法重置了摄像头,使用qv4l2查看,但是画面不对,而且我晃动摄像头画面没变化4.jpg

                      @veye_xumm 还有一个关于Image拷贝的问题想问一下您,官网上说xavier系列需要拷贝Image.sig文件到root下,那orin nano 需要吗?

                        @lakers 需要的。但是你现在已经过了那个阶段了。驱动已经正常加载了。

                          @veye_xumm 嗯嗯,好的。那这个摄像头为什么不出画面呢?会不会是dtb中i2c的问题呢?

                            @veye_xumm 老师如果说我要以别的格式看画面的话那我的gstreamer指令应该怎么修改呢?

                              执行一下这个,看看是否正常出帧率?

                              export WIDTH=2432
                              export HEIGHT=2056
                              export FPS=28
                              v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null

                                  @lakers 不停的打大于号吗?显示的帧率是多少?
                                  如果是这样,说明功能是正常的在采集和输出图像了。但是不知为何你用qv4l2的时候图像特别黑。
                                  你的镜头光圈打开了吗?

                                      那不对。你现在执行一下dmesg,看一下驱动层的输出。

                                          @lakers 没看到报错啊。你有没有配置触发模式之类的东西?
