How to build Trezor firmware?
-----------------------------
1. Install Docker (from docker.com or from your distribution repositories)
2. `` git clone https://github.com/trezor/trezor-mcu.git ``
3. `` cd trezor-mcu ``

4. `` ./firmware-docker-build.sh TAG `` (where TAG is v1.3.2 for example, if left blank the script builds latest commit)

This creates file `` output/trezor-TAG.bin `` and prints its fingerprint at the last line of the build log.

How to get fingerprint of firmware signed and distributed by SatoshiLabs?
-------------------------------------------------------------------------
1. Pick version of firmware binary listed on https://mytrezor.com/data/firmware/releases.json
2. Download it: `` wget -O trezor.signed.bin.hex https://mytrezor.com/data/firmware/trezor-1.1.0.bin.hex ``
3. `` xxd -r -p trezor.signed.bin.hex trezor.signed.bin ``
4. `` ./firmware-fingerprint.sh trezor.signed.bin ``
2015-03-21 09:44:30 +00:00
Step 4 should produce the same sha256 fingerprint like your local build (for the same version tag).

The reasoning for `` firmware-fingerprint.sh `` script is that signed firmware has special header holding signatures themselves, which must be avoided while calculating the fingerprint.
