### 三、tee_tee_os_kernel 构建指导 ###

1. TEEOS内核代码位置：`base/tee/tee_os_kernel`

2. TEEOS框架代码位置：`base/tee/tee_os_framework`

3. 切换目录至OpenHarmony源码根目录，输入以下指令进入Docker构建环境

```Bash
docker run -it --rm -v $(pwd):$(pwd) -w $(pwd) swr.cn-south-1.myhuaweicloud.com/openharmony-docker/docker_oh_full:3.2 bash
```

4. 输入以下指令构建杨帆开发板TEEOS

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

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