### 3. tee_tee_os_kernel building guide ###

1. TEEOS kernel code location: `base/tee/tee_os_kernel`
 
2. TEEOS framework code location: `base/tee/tee_os_framework`

3. Change the directory to the root directory of the OpenHarmony source code, and enter the following command to enter the Docker building environment:

```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. Enter the following command to build TEEOS for the Yangfan board:

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

5. The product is the TEEOS image: `base/tee/tee_os_kernel/kernel/bl32.bin`
