#### Tutorial about how to setup the OPTEE environment on QEMU
Here you find the steps to setup the environment to run OPTEE on QEMU. These
steps are available in the build page of the OPTEE github
(https://github.com/OP-TEE/build).
To get and build OPTEE on QEMU, you have to follow the steps below:
1. Install the following packages:
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:i386 libtool libz1:i386 make
mtools netcat python-crypto python-serial python-wand unzip uuid-dev
xdg-utils xterm xz-utils zlib1g-dev
2. Get the repo tool and make it executable:
wget https://storage.googleapis.com/git-repo-downloads/repo
chmod a+x repo
3. Create a directory for optee and enter inside it:
mkdir optee
cd optee
4. Get the source code:
./../repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml
./../repo sync
5. Get the toolchains:
cd build
make toolchains
6. Build the solution:
make
7. Run OPTEE on QEMU:
make run
8. When the process stops, the QEMU console will be waiting. Just type c to
continue. Two terminals will open: one with the "Rich OS" (Normal World) and
another with the "Trusted OS" (Trusted World - OPTEE).
9. In the Rich OS (Normal World), enter "root" to login. You now can test the
examples, running one of the following:
hello_world
aes
hotp
random
