To reproduce and verify the deterministic build:

# Clone the repository
git clone https://github.com/digitalbitbox/mcu.git
cd mcu

# Build deterministically (requires Vagrant and Virtualbox and OSX or Linux)
vagrant up
cp build-vagrant/bin/firmware.pad.bin firmware.deterministic.7.0.0.bin
vagrant halt

# Verify the deterministic binary
shasum -a 256 firmware.deterministic.7.0.0.bin  #  927eaf80fbfb82c0abcf105917f375ad3b2093af452ccb9aebc7f5a3253a20e0
