Francesco Domenico Servidio50f11012021-11-03 13:48:58 +0100[diff] [blame]23MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a
24common infrastructure for the bootloader and the system flash layout on
25microcontroller systems, and provides a secure bootloader that enables easy
26software upgrade.

Francesco Domenico Servidio50f11012021-11-03 13:48:58 +0100[diff] [blame]28MCUboot is not dependent on any specific operating system and hardware and
29relies on hardware porting layers from the operating system it works with.
30Currently, MCUboot works with the following operating systems and SoCs:
31- [Zephyr](https://www.zephyrproject.org/)
32- [Apache Mynewt](https://mynewt.apache.org/)
33- [Apache NuttX](https://nuttx.apache.org/)
34- [RIOT](https://www.riot-os.org/)
35- [Mbed OS](https://os.mbed.com/)

Francesco Domenico Servidio50f11012021-11-03 13:48:58 +0100[diff] [blame]39RIOT is supported only as a boot target. We will accept any new
40port contributed by the community once it is good enough.
