• 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.bin firmware.deterministic.2.2.0.bin

# Verify the deterministic binary
shasum -a 256 firmware.deterministic.2.2.0.bin  # 65c10a5ba0e83b514c5b09be67f6967b457efa366709c356b6a4b9e27ff9171f
