      那不对。你现在执行一下dmesg,看一下驱动层的输出。

              @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。
