【OP-TEE 3.8.0学习】001_运行环境的搭建及编译
一、OP-TEE开发环境搭建(Ubuntu-20.04 & op-tee 3.8.0)
1. OP-TEE开发环境需要使用各种依赖库
sudo apt-get install android-tools-adb android-tools-fastboot autoconf automake bc \
bison build-essential cscope curl device-tree-compiler expect flex ftp-upload gdisk \
iasl libattr1-dev libc6:i386 libcap-dev libfdt-dev libftdi-dev libglib2.0-dev \
libhidapi-dev libncurses5-dev libpixman-1-dev libssl-dev libstdc++6 libtool \
zlib1g zlib1g:i386 libtool-doc gfortran make mtools netcat python-crypto nzip \
uuid-dev xdg-utils xterm xz-utils python3-pip python3-pyelftools texinfo texlive \2. git配置
git config --global user.email "[email protected]"
git config --global user.name "Your Name"3. 安装repo
$ wget https://mirrors.tuna.tsinghua.edu.cn/git/git-repo
$ sudo chmod 777 git-repo
$ sudo mv git-repo /usr/bin/repo4. 获取OP-TEE源代码
repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml --repo-url=https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -b 3.8.0获取op-tee源代码时出现如下异常：
/usr/bin/env: ‘python’: No such file or directory针对上述异常的解决办法：
5. sync OP-TEE源代码
repo sync -c -j16sync后op-tee工程目录如下：
如果在执行repo sync时出现“remote:Repository not found”的报错提示，则需要修改open-tee/.repo目录中的manifest.xml文件，将该文件中所有project域中的“.git”删除，也可以通过如下指令进行修改：
sed -i "s/\.git//g" .repo/manifest.xml修改完成之后，重新执行repo sync来获取OP-TEE的代码。
6. 获取编译OP-TEE的toolchain
$ cd build
$ make -f toolchain.mk toolchains查看toolchain.mk文件可知，执行make指令之后，系统会去下载toolchains的tar包，包括32位和64位的编译链接工具，下载完成后会进行解压操作。
define dltc
@if [ ! -d "$(1)" ]; then \
mkdir -p $(1); \
echo "Downloading $(3) ..."; \
# 下载
curl -s -L $(2) -o $(TOOLCHAIN_ROOT)/$(3).tar.xz; \
# 解压
tar xf $(TOOLCHAIN_ROOT)/$(3).tar.xz -C $(1) --strip-components=1; \
fi
endef如果执行“make -f toolchain.mk toolchains”命令后，一直卡在“Downloading xxx ...”那。
手动到https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads下载指定toolchain（toolchain.mk指定了AARCH32_GCC_VERSION和AARCH64_GCC_VERSION）。
这里下载的是gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz和gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz
将下载的toolchain的tar包放到op-tee源代码的根目录下的toolchains目录，并进行解压
$ tar xf gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf.tar.xz -C aarch32 --strip-components=1
$ tar xf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C aarch64 --strip-components=17. 编译QEMU
$ cd build
$ make -f qemu_v8.mk all编译时报出来的问题1：

$ cd build
$ make -f qemu_v8 run-only运行上述命令后将会启动两个分别属于安全世界状态和正常世界状态的terminal，用于显示OP-TEE和Linux内核的日志数据，然后加载OP-TEE镜像与Linux的镜像以及文件系统。
二、测试环境
1. 启动模拟器
运行OP-TEE之后，在qemu窗口输入c或者cont启动模拟器，此时会在安全世界终端显示OP-TEE日志数据，在正常世界状态终端显示Linux内核日志数据。
