MCUboot is a secure bootloader for 32-bit microcontrollers.
MCUboot 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 various operating systems and SDKs, such as Zephyr and the nRF Connect SDK.
The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
You can find additional documentation on the bootloader in the source files. For more information, use the following links:
