2.2 配置
在 BK72XX_SDK/beken378/app/config 下有几个默认配置，带有 sys_config_ 前缀。
| Configuration | description |
| sys config bk7231.h | Configuration for BK7231 |
| sys config bk7231n.h | Configuration for BK7231N |
| sys config bk7231u.h | Configuration for BK7231U |
| sys config BK7251.h | Configuration for BK7251 |
3.环境设置
3.1 安装工具链
交叉编译器在 toolchain 目录下，用于构建库，要使用已有的库，请在构建时使用相同的工具链。
4.构建
4.1 FreeRTOS 构建
4.1.1 构建命令
$ make help # 显示如何编译的帮助
$ make clean # 清理
$ make bk7231u # 为 bk7231u 构建固件
$ make bk7231n # 为 bk7231n 构建固件
$ make bk7251 # 为 bk7251 构建固件
编译完成后，将在调试目录下生成固件
