Firmware
What is Bootloader?
A bootloader is a small program that runs first when a device powers on, initializing hardware and loading the main firmware — and often enabling firmware updates over the air or over a serial/USB link.
A robust, secure bootloader is the foundation of field-updatable products, verifying firmware authenticity and safely recovering if an update is interrupted.
