TREZOR One Bootloader and Firmware
How to build the TREZOR bootloader, firmware and emulator
Ensure that you have Docker installed. You can follow Docker's installation instructions.
Clone this repository:
git clone https://github.com/trezor/trezor-mcu.git`
cd trezor-mcu
Use the build.sh command to build the images.
- to build bootloader 1.6.0 and firmware 1.7.0:
./build.sh bl1.6.0 v1.7.0 - to build latest firmware from master:
./build.sh - to build the emulator from master:
./build.sh EMU - to build the emulator for version 1.7.0:
./build.sh EMU v1.7.0
Build results are stored in the build/ directory. File bootloader-<tag>.bin represents
the bootloader, trezor-<tag>.bin is the firmware image, and trezor-emulator-<tag>.elf
is the emulator executable.
You can use TREZOR_OLED_SCALE environment variable to make emulator screen bigger.
How to get fingerprint of firmware signed and distributed by SatoshiLabs?
- Pick version of firmware binary listed on https://wallet.trezor.io/data/firmware/1/releases.json
- Download it:
wget -O trezor.signed.bin https://wallet.trezor.io/data/firmware/1/trezor-1.6.1.bin - Compute fingerprint:
tail -c +257 trezor.signed.bin | sha256sum
Step 3 should produce the same sha256 fingerprint like your local build (for the same version tag). Firmware has a special header (of length 256 bytes) holding signatures themselves, which must be avoided while calculating the fingerprint, that's why tail command has to be used.
How to install custom built firmware?
WARNING: This will erase the recovery seed stored on the device! You should never do this on TREZOR that contains coins!
- Install python-trezor:
pip install trezor(more info) trezorctl firmware_update -f build/trezor-TAG.bin
Building for development
If you want to build device firmware, make sure you have the GNU ARM Embedded toolchain installed. You will also need Python 3.5 or later and pipenv.
- If you want to build the emulator instead of the firmware, run
export EMULATOR=1 TREZOR_TRANSPORT_V1=1 - If you want to build with the debug link, run
export DEBUG_LINK=1. Use this if you want to run the device tests. - When you change these variables, use
script/setupto clean the repository
- To initialize the repository, run
script/setup - To initialize a Python environment, run
pipenv install - To build the firmware or emulator, run
pipenv run script/cibuild
If you are building device firmware, the firmware will be in firmware/trezor.bin.
You can launch the emulator using firmware/trezor.elf. To use trezorctl with the emulator, use
trezorctl -p udp (for example, trezorctl -p udp get_features).
