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.6.1.1.bin
vagrant halt

# Verify the deterministic binary
shasum -a 256 firmware.deterministic.6.1.1.bin  #  98315c07148df78c35282a9c8e3a310905317df20de938e07409a6de503c3f56
