David Brown 0d1b0b952e zephyr: Enable MPU flash writing 
Recent Zephyr trees require this config option to be set in order to be
able to write to the flash device.  Without it, targets with an MPU
enabled will abort during startup, usually before even printing a
message to the UART.

mcuboot

Overview

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. RIOT is currently supported as a boot target with a complete port planned.

Roadmap

The issues being planned and worked on are tracked on Jira. To participate please visit:

https://runtimeco.atlassian.net/projects/MCUB/summary

Browsing

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

https://runtimeco.atlassian.net/wiki/discover/all-updates

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
  • boot/mynewt: Mynewt bootloader app
  • imgtool: A tool to securely sign firmware images for booting by mcuboot.
  • sim: A bootloader simulator for testing and regression
