This is MCUboot version 2.1.0

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a

common infrastructure for the bootloader and the system flash layout on

microcontroller systems, and provides a secure bootloader that enables easy

software upgrade.

MCUboot is not dependent on any specific operating system and hardware and

relies on hardware porting layers from the operating system it works with.

Currently, MCUboot works with the following operating systems and SoCs:

- [Zephyr](https://www.zephyrproject.org/)

- [Apache Mynewt](https://mynewt.apache.org/)

- [Apache NuttX](https://nuttx.apache.org/)

- [RIOT](https://www.riot-os.org/)

- [Mbed OS](https://os.mbed.com/)

- [Espressif](https://www.espressif.com/)

- [Cypress/Infineon](https://www.cypress.com/)

RIOT is supported only as a boot target. We will accept any new

port contributed by the community once it is good enough.

## MCUboot How-tos

See the following pages for instructions on using MCUboot with different

operating systems and SoCs:

- [Zephyr](docs/readme-zephyr.md)

- [Apache Mynewt](docs/readme-mynewt.md)

- [Apache NuttX](docs/readme-nuttx.md)

- [RIOT](docs/readme-riot.md)

- [Mbed OS](docs/readme-mbed.md)

- [Espressif](docs/readme-espressif.md)

- [Cypress/Infineon](boot/cypress/README.md)

There are also instructions for the [Simulator](sim/README.rst).
