  Dalton Cézane GomesValadaresEmbedded Lab (UFCG) - IFPE#### Tutorial about how to setup the OPTEE environment on QEMUHere you find the steps to setup the environment to run OPTEE on QEMU. Thesesteps 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-dev2. Get the repo tool and make it executable:wget https://storage.googleapis.com/git-repo-downloads/repochmod a+x repo3. Create a directory for optee and enter inside it:mkdir opteecd optee4. Get the source code:./../repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml./../repo sync5. Get the toolchains:cd buildmake toolchains6. Build the solution:make7. Run OPTEE on QEMU:make run8. When the process stops, the QEMU console will be waiting. Just type c tocontinue. Two terminals will open: one with the "Rich OS" (Normal World) andanother with the "Trusted OS" (Trusted World - OPTEE).9. In the Rich OS (Normal World), enter "root" to login.
