# tee_tee_os_kernel 仓介绍 #

## 简介 ##

OpenTrustee提供了一个可信执行环境（Trusted Execution Environment，TEE），运行在受硬件隔离的安全区域中。OpenTrustee是一套完整的TEE解决方案，包含多个部件，系统架构如图所示：

## tee_tee_os_kernel 构建指导 ##
tee_tee_os_framework与tee_tee_os_kernel共同构建TEEOS，单独构建命令如下：

```Bash
./build.sh --product-name rk3568 --build-target tee --ccache
```

构建产物为TEEOS镜像：`base/tee/tee_os_kernel/kernel/bl32.bin`
