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 trezor.bin in current directory 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 ``

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.
