XR871 SDK Code Structure

• bin - the directory in which pre-build binary files are stored
  用于启动和wlan功能的二进制文件
• include - the directory in which SDK header files are stored
  头文件目录
• lib - the directory in which the pre-build libraries are stored
  预编译的库文件存放路径，或者make lib编译出的库文件存放路径
• project - the directory in which the demo projects and the public modules are stored
  存放一些示例工程，以及一些公共模块代码
• src - the directory in which the source code of the base module are stored
  存放一些基础模块的源代码

XR871 SDK GCC Configuration

GCC Configuration File(03_SDK/xr871sdk/gcc.mk) defines the toolchain path and the compile and link flags for XR871 platform. You have to configure the value of 'CC_DIR' to your GCC install path, otherwise you will get an error result like "arm-none-eabi-gcc: Command not found" when you execute the command "make lib" or "make".
gcc.mk文件是gcc的配置文件，其中定义了工具链路径以及在XR871平台上编译和连接的参数，您需要在编译之前配置CC_DIR到你自己的gcc安装路径，否则在执行make的时候将会受到类似“arm-none-eabi-gcc: Command not found”的错误信息。
