  • 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.2.1.1.bin

# Verify the deterministic binary
shasum -a 256 firmware.deterministic.2.1.1.bin  #  073197f33db3e4840945ac4d46af5cbf3b92812e1bd24fde38b831d942c667ff
