      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?

                                            @lakers 你现在用脚本读取一下是不是流模式? 如果不是流模式,配置回流模式,再尝试测试。
