【电路图】

注意13脚MCLK0必须外接24MHz有源晶振，不能用RV1106的I/O口输出的24MHz时钟，否则OV5640 I2C接口无响应。

如果启动的是自己的根文件系统，那么要先加载下面的ko模块，才能运行ov5640拍照程序。
insmod /root/test/ov5640/drivers/video_rkcif.ko
insmod /root/test/ov5640/drivers/phy-rockchip-csi2-dphy-hw.ko
insmod /root/test/ov5640/drivers/phy-rockchip-csi2-dphy.ko
echo 1 > /sys/module/video_rkcif/parameters/clr_unready_dev

这些驱动文件来自幸狐内核镜像里面生成的output/out/sysdrv_out/kernel_drv_ko文件夹。
加载完这些ko模块，并且执行了echo 1指令后，就会有/dev/video0和/dev/v4l-subdev0这两个设备文件出现。
加载完video_rkcif.ko模块后就会出现/dev/video0设备文件。
执行完echo 1命令后就会出现/dev/v4l-subdev0设备文件。

启动ov5640拍照程序后，会有下面的串口打印，不用管。
