      @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。

                                      @veye_xumm 不好意思理解错了,我这个是流模式的,我用您提供的sample中的 show.grey.py文件可以看见图像但帧率极低,用qv4l2却看不到图像,显示一片黑8.jpg 9.jpg

                                        python这个demo是帧率很低的。因为是纯软件跑到cpu上作的数据搬移。你回头开发自己的程序的时候,可以避免这一点。

                                        qv4l2这个可能是因为分辨率太高了,qv4l2这个软件的兼容性的问题。

                                        整体来看,我觉得驱动已经通了,你可以跑跑我们wiki上其他的例子了。
