      我按照https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_jetson/zh#.E6.B5.81.E6.A8.A1.E5.BC.8F
      进行操作,无法从raw-mipi-sc132m获得图像。
      安装方式如图,只通过15pin异面FFC连接raw-mipi-sc132m相机与Jetson Nano B01主板。

      当前L4T版本如图
      图片2.jpg
      在第3节更新Jetson系统中我不确定是否需要更新,跳过了此步。
      dmesg | grep mvcam能够检测到相机型号
      此后尝试使用流模式进行采集图像数据,按照上述手册进行操作。
      获取不到数据,控制台输出如图。

      使用qv4l2预览,预览窗口为黑屏,且触发源会被变回硬触发(qv4l2输出)?关闭后再查询又变回软触发。

      目前无法获取图像,步骤无误的话,相机损坏的可能性有吗?

        你断电重启一下jetson,然后执行:

        export WIDTH=1080
        export HEIGHT=1280
        export FPS=120
        
        v4l2-ctl --set-ctrl roi_x=0
        v4l2-ctl --set-ctrl roi_y=0
        v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY
        
        v4l2-ctl --set-ctrl frame_rate=$FPS
        v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null
        

        试一下

          这是输出

          不会自动结束,手动ctrl + C后得到的/dev/null大小0字节。

            后续使用触发模式,软触发获取图像同样获取不到数据。触发正常,但是没有数据,下面是我按照手册步骤进行尝试获取数据的过程。

              @cheesefish 在你执行预览或者触发,应当有图,但是收不到图的时候,执行一下

              dmesg
              

              看一下最新的日志,有没有什么报错?

                  @cheesefish 你这个应该是抓拍模式报的错误吧? 能不能重启一下,把摄像头配置为视频流模式,用视频流模式跑一下,然后dmesg看看错误?
                  另外你的Image是我们编译好的,还是你自己编译的?
                  感觉问题引入到camera或者nano的mipi数据接口,硬件出问题了。之前你操作有没有插反ffc 线,或者带电插拔mipi接口排线?

                        视频流模式,帧率统计报错如下

                        抓取图片时的报错如下
                        287ea581-2963-4444-a4fd-e0ea0b0f4b11-image.png

                        使用的Image是你们编译好的。问题原因多半是最初ffc先插反了,要解决这个问题,需要做些什么?更换新的相机能解决吗?
