CoolPi 4B OV5647 摄像头图片全黑
-
在CoolPi 4B 上使用Rpi Camera rev1.3的摄像头，最开始读取/dev/video11，光线很暗，发现rkaiq_3a_server没有跑起来，所以使用Coolpi launchpad上的rkaiq_3a_server进行测试，server没有报错，但是v4l2读取到的图片全黑（试着用手电筒对着摄像头照，也是全黑的）
使用的内核是自己编译的，是github上的develop分支，两天前clone下来并编译的，除了更新rknpu驱动之外没有动其他的地方

请问一下大佬们有遇到过类似的情况吗，感激不尽！！ -
@traceback
使用QV4L2测试一下节点，确实是否可以正常获取图像，除了型号以外，不同的sensor镜头也会对图像产生影响。 -
@george
您好，这是qv4l2的截图 -
@george 您好，我又确认了一下，在用systemctl关闭rkaiq的服务之后，读取/dev/video11就是正常的未经isp处理的图像，颜色非常暗，然后开启rkaiq_3a_server之后图像就是全黑的，使用v4l2抓图像是没有读出来数据，感觉不像是读出来了全黑的图
