      我在第三方的nx板子上使用命令
      Nvv4l2camerasrc device=/dev/video0 ! Video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)640, height=(int)480 !nvvidconv ! Video/x-raw(memory:NVMM), videoconvert ! Video/x-raw, format=(string)BGR启动四路sc132相机的时候,经常会有一路相机是失效的,拿不到数据,但是我单独启动的每路相机的时候又是好的,请问这个是什么原因呢,就有时候能起得来,大部分时候起不来,是这个sd卡的读取速度太慢读不过来吗,我在用固态硬盘读取的同样的第三方的板子是好的

          你这个板子的mipi接口的供电能力最好确认一下,我们这个模组的功耗稍微高一些。
          你有万用表的话,最好量一下FFC排线上的3.3V电压实际是多少?

          Questions will be answered as soon as possible, please be patient.
          如果你使用中文,请直接用中文提问。

            @veye_xumm 你好,我这个后来每次有问题重新插拔一下那个线就好了,这个是因为那个我用的硬件触发的模式,触发的信号过低的时候相机崩溃的问题吗,每次崩溃完以后,我执行./cs_mipi_i2c.sh -w -f sysreboot -p1 [value] 重启的话,是不是能修复呢,还是说一定要重启

              我有时候重启程序也会能读到,但是显示的图像不正常

                重新插拔哪个线? 有没有量一下上次说的camera的供电电平是多少?我感觉跟你触发的信号电平关系不太大,主要还是摄像机的供电电平。
                ADP-N1是支持独立的12V DC供电的,如果你不方便测量可以用独立供电试一下。

                  @veye_xumm 确实,感觉是启动瞬间供电功率不够的问题,我分开启动就没有这个问题了
