Build instructions

Build instructions for Emulator (Unix port)

Run the following to checkout the project:

git clone --recursive https://github.com/trezor/trezor-core.git
cd trezor-core

If you are building from an existing checkout, don't forget to use the following to refresh the submodules:

make vendor

Install the required packages, depending on your operating system.

Debian/Ubuntu:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install scons libsdl2-dev:i386 libsdl2-image-dev:i386 gcc-multilib

Fedora:

sudo yum install scons SDL2-devel.i686 SDL2_image-devel.i686

OpenSUSE:

sudo zypper install scons libSDL2-devel-32bit libSDL2_image-devel-32bit

Arch:

sudo pacman -S gcc-multilib scons lib32-sdl2 lib32-sdl2_image

Mac OS X:
```
brew install scons sdl2 sdl2_image
```
Windows: not supported yet, sorry.

Run the build with:

make build_unix

Now you can start the emulator:

./emu.sh

Build instructions for Embedded (ARM port)

Requirements

You will need the GCC ARM toolchain for building and OpenOCD for flashing to a device. You will also need Python dependencies for signing.

Debian/Ubuntu

sudo apt-get install scons gcc-arm-none-eabi libnewlib-arm-none-eabi

OS X

Download gcc-arm-none-eabi
Follow the install instructions
To install OpenOCD, run brew install open-ocd
Run make vendor build_boardloader build_bootloader build_firmware

Building

sudo pip3 install pipenv
pipenv install
pipenv run make vendor build_boardloader build_bootloader build_firmware

Uploading

Use make upload to upload the firmware to a production device (with a bootloader).

Flashing

For flashing firmware to blank device (without bootloader) use make flash, or make flash STLINK_VER=v2-1 if using a ST-LINK/V2.1 interface. You need to have OpenOCD installed.
