Build op-tee development environment based on qemuv8

development environment ：Ubuntu 22.04 desktop virtual machine

1、 Environmental requirements

$ sudo dpkg --add-architecture i386 $ sudo apt-get update

$ sudo apt-get install android-tools-adb android-tools-fastboot autoconf automake bc bison build-essential ccache codespell cpio cscope curl device-tree-compiler expect flex ftp-upload gdisk iasl libattr1-dev libcap-dev libcap-ng-dev libfdt-dev libftdi-dev libglib2.0-dev libgmp-dev libhidapi-dev libmpc-dev libncurses5-dev libpixman-1-dev libssl-dev libtool make mtools netcat ninja-build python-crypto python3-crypto python-pyelftools python3-pycryptodome python3-pyelftools rsync unzip uuid-dev xdg-utils xterm xz-utils zlib1g-dev

2、 install repo

$ mkdir ~/bin

$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo

$ chmod a+x ~/bin/repo

$ export PATH=~/bin:$PATH

change repo Get source , stay /etc/profile At the end of the document, add the following , Then restart the system

export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'

3、 obtain OP-TEE Code

$ mkdir OP-TEE

$ cd OP-TEE/

$ repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml

$ repo sync -j4 --no-clone-bundle

remarks 1： Tips “Failed to connect to boringssl.googlesource.com port 443: Connection timed out” The error is because the relevant website cannot be accessed , You can use the following command to replace the URL source ：

$ git config --global url."https://github.com/google/boringssl.git".insteadOf "https://boringssl.googlesource.com/boringssl"

$ git config --global url."https://hub.fastgit.org/google/boringssl.git".insteadOf "https://boringssl.googlesource.com/boringssl"

remarks 2：sync The operation will be because github Link failure and error , Re execute after reporting an error . but sync All libraries will be updated every time , As long as one library link fails, an error will be reported , But maybe the library has been downloaded . Therefore, you can view the corresponding manifest file , Check whether all libraries have been downloaded . If you have finished downloading, you can go to the next step .manifest.xml The file in .repo Under the table of contents .

4、 compile

$ cd ./build

$ make -j2 toolchains

$ make -j `nproc`

5、 function qemu

Still in build/ Under the table of contents

$ make run

After correct operation, two virtual serial port terminals will pop up , The port number is 54320 It's an unsafe system , The port number is 54321 For the security system ：

Get into qemu Input after the terminal c Start the system ：

(qemu) c

Non safety system （Linux） Can pass root The user login

Security system ：

remarks 1： During operation, it may report python Command not found error , however ubuntu It has been installed python. This is because of the name , Installation is python2 and python3, Here you can create a link to solve the problem ：

$ sudo ln -s /usr/bin/python3 /usr/bin/python

remarks 2： First execution make run Will compile relevant components and then run qemu, Then you can run directly make run-only Direct operation .

6、 Run the test program

Use ps Command check tee-supplicant Whether the process exists

  function xtest Test routine

$ xtest
