## Overview

|
|
MCUboot is a secure bootloader for 32-bit MCUs. The goal of MCUboot is to
|
2017-09-12 03:06:38 +08:00
|
|
|
define a common infrastructure for the bootloader, system flash layout on
|
|
|
|
microcontroller systems, and to provide a secure bootloader that enables
|
2017-09-12 03:04:34 +08:00
|
|
|
easy software upgrade.
|
|
|
|
|
2017-09-12 03:06:38 +08:00
|
|
|
MCUboot is operating system and hardware independent, and relies on
|
2017-09-12 03:04:34 +08:00
|
|
|
hardware porting layers from the operating system it works with. Currently
|
|
|
|
MCUboot works with both the Apache Mynewt, and Zephyr operating systems, but
|
|
|
|
more ports are planned in the future. RIOT is currently supported as a boot
|
|
|
|
target with a complete port planned.
