本文讲述怎样将VEYE系列和CS系列模组接入到英伟达公司的Jetson TX2和AGX Xavier开发板以及我们兼容的其他TX2主板上。采用的软件版本为(Jetpack4.2.2,L4T版本r32.2.1)以及(Jetpack4.3,L4T版本r32.3.1)，我们提供了编译好的固件和源代码两种方式来方便用户的使用。
    
VEYE-MIPI-327/CS-MIPI-IMX307是星光级内置ISP的摄像头模组，输出为MIPI-CSI2接口UYVY流模式。对于图像效果参数，我们并没有采用V4L2接口实现，而是采用了DRA(Directly Register Access)模式，我们提供了一组Shell脚本直接控制摄像头模组。
