boot: Check shared area more carefully before init

When the shared data area is not exclusively used by MCUboot, but also
by other boot stages it is inappropriate to initialize (erase) the
shared area based on a global variable. It must check the magic value
at the beginning of the area plus it should sanity-check other
available values for a case when memory garbage matches the magic
value.

mcuboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is mcuboot version 1.8.0-dev

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 simple software upgrades.

MCUboot is operating system and hardware independent and relies on hardware porting layers from the operating. 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.

Using MCUboot

Instructions for different operating systems can be found here:

Roadmap

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

MCUBoot GitHub Issues

Issues were previously tracked on MCUboot JIRA , but it is now deprecated.

Browsing

Information and documentation on the bootloader are stored within the source.

It was previously also documented on confluence: MCUBoot Confluence however, it is now deprecated and not currently maintained

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
