海思HISI3556V200的开发板,硬件上是单个IMX307的摄像头,但是从原厂提供过来的软件SDK版本中的dashcam配置文件没有单IMX307的配置。
因此，需用自己手动去配置。
这里我们使用 hi3556v200_dashcam_demb_imx307_bt656_1080p30_carrecorder_128M_config 这个文件作为配置文件，将这个文件copy到SDK根目录并修改为.config
注意:以下操作,全在海思的开发环境下执行。
一、配置SDK
在根目录执行
make menuconfig
然后去掉如下选项.
保存退出。
二、增加参数配置
1、添加参数目录
在目录
reference/dashcam/modules/param/inicfg/hi3559v200/carrecorder
添加 imx307_128M 文件夹（在执行编译的时候,会到这个文件夹查找参数，所以这个文件夹是必须的）
我的做法是
复制并改名
imx307_bt656_1080p30_128M =================> imx307_128M
2、修改IMX307_128M参数，将其修改为单摄像头
A、去掉第二个摄像头的相关文件
B、修改摄像头2所涉及的文件
如图所示，总共有7个文件需要修改。

3、重新编译及烧录新固件开发板
在SDK根目录下执行
make all
等待编译完成之后，从目录 reference/out/hi3559v200_dashcam_carrecorder_demb_imx307/burn/spinor 中获取相应的升级镜像，烧录到开发板即可。
