MCUboot

This is MCUboot version 2.3.0-dev

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines acommon infrastructure for the bootloader and the system flash layout onmicrocontroller systems, and provides a secure bootloader that enables easysoftware upgrade.

MCUboot is not dependent on any specific operating system and hardware andrelies on hardware porting layers from the operating system it works with.Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any newport contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with differentoperating systems and SoCs:

There are also instructions for theSimulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. Togive your input, visitMCUboot GitHubIssues.
