Introduction

The Bootloader Library can be used to upgrade firmware on a target device without the need for an external programmer or debugger.

A Bootloader is a small application that starts the operation of the device. A Bootloader does not fully operate the device, but can perform various functions prior to starting the main application.

Such functions can include:

Firmware upgrades
Application integrity
Starting the application

Supported bootloaders: UART, I2C, SPI, CAN, Serial Memory, File System, USB, Ethernet and OTA
