# 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 using GitHub issues. To participate
|
|
please visit:
|
|
|
|
[MCUboot Issues](https://github.com/JuulLabs-OSS/mcuboot/issues)
|
|
|
|
~~Issues were previously tracked on [MCUboot JIRA](https://runtimeco.atlassian.net/projects/MCUB/summary)
|
|
, but it is now deprecated.~~
|
|
|
|
## Browsing
|
|
|
|
Information and documentation on the bootloader is stored within the source.
|
|
|
|
~~It was previously also documented on confluence: [Confluence page](https://runtimeco.atlassian.net/wiki/discover/all-updates)
|
|
, but it is now deprecated and not currently maintained~~
|
|
|
|
