Build
Building for Trezor Model One? See the legacy documentation.
New Project
Run the following to checkout the project:
git clone --recurse-submodules https://github.com/trezor/trezor-firmware.git
cd trezor-firmware
uv sync
cd core
After this you will need to install some software dependencies based on what flavor of Core you want to build. You can either build the Emulator or the actual firmware running on ARM devices. Emulator (also called unix port) is a unix version that can run on your computer. See Emulator for more information.
Existing Project
If you are building from an existing checkout, do not forget to refresh the submodules
and sync the uv
environment:
git submodule update --init --recursive --force
uv sync
Uv
We use uv to install and track Python dependencies. You
need to install it, sync the packages and then use uv run
for every command or
activate the uv
environment before typing any commands. The commands in this section
suppose you are in a uv
environment!
uv sync
source .venv/bin/activate
