          @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。

                                          @veye_xumm 请问一下这个怎么查流模式呢?您这个回流模式怎么配置呢?

                                            IMX462不支持raw8,所以无法用qv4l2直接显示预览。你需要抓图之后用专门的yuv播放器进行图像显示。

                                            不是【回流】模式,而是配置回去到流模式。 你之前不是配置过吗? 用

                                            v4l2-ctl --get-ctrl trigger_mode
                                            

                                            可以读取当前模式。
                                            用mv_mipi_i2c.sh也可以的。具体查一下文档。
