Introduction to MCUboot: Secure Bootloader and Easy Firmware Updates

summary
MCUboot is a compact secure bootloader for microcontrollers that enforces a two-slot layout with a scratch area to allow recovery from interrupted updates. It supports three update strategies—swap with scratch, swap by move, and overwrite—requires signed images verified by image_tool, and supports EC-256 signatures and AES encryption (also RSA and Ed25519). The demo signs example keys, flashes images to ESP32 flash regions, shows that unsigned images fail to boot, and then performs a successful swap and confirmed boot of the new signed image.
