Microchip Bootloaders
Bootloaders are used to upgrade firmware on a target device without using an external programmer or debugger. Commonly used with microcontrollers (MCUs), a bootloader contains code that loads and executes an application program. Bootloaders can also perform additional tasks such as validating the code integrity and authenticity.
