        你用的相机型号是什么? 用哪个命令做的取图?

          @veye_xumm 相机型号:raw-mipi-ar0234m,使用的抓图命令是:v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1200,pixelformat=GREY --stream-mmap --stream-count=1 --stream-to=y8.raw

            应该跟这个没关系。

            你这个命令也没有问题。

            很奇怪,按理说应该不会有这些mipi协议上的错误,请拍一下你的硬件系统图给我看看。

                确认下这个3.3V是否稳定输出(幅值>3.2V)。100mA@1.2V(或1.5V)看起来功率是不够用的。

                  功率不够需要怎么解决,外加电源吗?功率需达到多少可以呢?

                    功耗是657mW

                    你这个是带负载测量的吗?使能取图之后再测。

                        @lin 那就明确了问题所在。你可以先从主板上飞线一个3.3V先测着看看。

                              @veye_xumm 可以采集了,能否请教一下两者的区别在哪里呢?

                                @lin v4l2-ctl这个命令可能在这个板子的版本有bug。

                                  @veye_xumm 您是说,其他相机连上去,v4l2-ctl这个命令采集图像也是会出现问题是吗?是这块板本身的内核缺陷吗?还是其他原因
