1. 概述
本文描述了optee-os在Qemu仿真开发环境的搭建
2. 环境搭建
2.1 创建项目根目录
mkdir optee_qemu_project
2.1 安装repo和配置板卡
repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml -b 3.18.0 --repo-url=https://gerrit-googlesource.lug.ustc.edu.cn/git-repo
因为国内无法访问谷歌，因此需要指定清华的源。版本选择最新的3.18.0版本，如果下载失败，重新下载的话，需要删除.repo目录。
下载成功的输出信息如下：
如果下载失败，重新下载的话，需要删除.repo目录。
repo has been initialized in /home/zhoushimin/workspace/optee_qemu_project/
If this is not the directory in which you want to initialize repo, please run:
rm -r /home/zhoushimin/workspace/optee_qemu_project//.repo
and try again.
2.2 下载源码
repo sync -j $(nproc)
-j $(nproc)选项表示根据CPU核心数配置最大线程加速。
如果出现网络不好，可以使用VPN，博主使用VPN下载速度还可以。
2.3 下载工具链
cd build
make -f toolchains.mk
下载完毕后，会在上层目录，也就是根目录下创建toochains工具链文件夹
3. 编译
cd build
make -f qemu_v8.mk all
3.1 编译过程中遇到的问题
3.1.1 提示找不到OpenSC-0.21.0.tar.gz: No such file or directory
opensc下载目录发生变化，opensc-0.21已不存在，需要调整，修改build/br-ext/package/opensc/opensc.mk文件中的
OPENSC_VERSION = 0.21.0
OPENSC_SOURCE = /OpenSC-$(OPENSC_VERSION).tar.gz
为
OPENSC_VERSION = 0.22.0
OPENSC_SOURCE = /opensc-$(OPENSC_VERSION).tar.gz
3.1.2 编译出错，仅清除指定目录编译输出的方法
make -C ../imx-optee-test/ clean TA_DEV_KIT_DIR=/home/zhoushimin/workspace/imx8qxp-mek/build/../optee_os/out/arm/export-ta_arm64
4. 运行
cd build
make -f qemu_v8.mk run-only
启动后除了原来的终端，会弹出另外的2个终端窗口，一个为TEE运行环境跑OPTEE OS，一个REE运行环境跑Linux OS
注释：
- REE（Rich Execution Environment）是所有移动设备通用的环境，运行通用的 OS（Operating System），例如 Android，IOS 系统等
- TEE （Trusted Execution Environment ）是可信执行环境。通常用来进行数字版权管理（DRM : Digital Rights Management ）、移动支付和敏感数据保护。
TEE运行唤醒窗口输出：
REE运行环境窗口输出：
执行终端的输出如下：
在执行终端输入c或者cont启动模拟器
(qemu)c
可以看到REE的打印日志：
