# mcuboot

## Overview

MCUBoot is a secure bootloader for 32-bit MCUs.   The goal of MCUBoot is to 
define a common infrastructure for the bootloader, system flash layout on 
microcontroller systems, and to provide a secure bootloader that enables 
easy software upgrade.

MCUboot is operating system and hardware independent, and relies on 
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.

## Roadmap

The issues being planned and worked on are tracked on Jira. To participate
