Marti Bolivar f4d0e1adf2 zephyr: turn off I2C 
Upstream Zephyr is making a habit of enabling subsystems on any board
that supports them. That's a potential security risk if any of those
allow interference with the running bootloader, and is currently
exceeding mcuboot's flash allowance on some STM32 targets,
e.g. 96b_carbon. Turn off I2C to restore the build for those.

README.md

mcuboot

This is mcuboot, version 0.9.0

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:

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
