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.
The MCUBoot project was originally taken from the Apache Mynewt operating system, which had secure boot and software upgrade functionality instrinsic to it. Currently development is heads down on a first release of MCUboot that works across both the Zephyr operating system and Apache Mynewt operating system.

Information and documentation on the bootloader is stored within the source, and on confluence:

For more information in the source, here are some pointers:
- boot/bootutil: The core of the bootloader itself.
- boot/boot_serial: Support for serial upgrade within the bootloader itself.
- boot/zephyr: Port of the bootloader to Zephyr
- imgtool: A tool to securely sign firmware images for booting by mcuboot.
- sim: A bootloader simulator for testing and regression
