    文章目录

    写在开始：

    • 博客简介：专注AIoT领域，追逐未来时代的脉搏，记录路途中的技术成长！
    • 博主社区：AIoT机器智能, 欢迎加入！
    • 专栏简介：imx8qxp小白从拿到板子到完成项目的过程记录
    • 面向人群：嵌入式工程师

    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

    • 1

    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 

    • 1

    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)

    • 1

    -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

    • 1
    • 2

    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

    • 1
    • 2

    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

    • 1
    • 2

    为

    OPENSC_VERSION = 0.22.0
OPENSC_SOURCE = /opensc-$(OPENSC_VERSION).tar.gz

    • 1
    • 2

    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

    • 1

    4. 运行

    cd build
make -f qemu_v8.mk run-only

    • 1
    • 2

    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：

    image-20220908181855526

    REE运行环境窗口输出：

    image-20220908181903446

    执行终端的输出如下：

    image-20220908181926166

    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：
