sim: Add debugging ptable to image dumps

Add a `debug_dump()` method to `Images` to allow the images to be
written to a file.  The dependency test will call this if the
environment variable MCUBOOT_DEBUG_DUMP is set.

In order to make these debug dumps more useful, add a simple partition
table to the beginning of the image (where MCUboot would reside on
target).  This has a simple header, and then entries for each partition,
using the partition ids used within the simulator.  This allows the
image to be more easily used by external tools.

As an example, `scripts/mcubin.bt` is a binary template for the [010
Editor](https://www.sweetscape.com/010editor/), allowing it to decode
and show the details of images from MCUboot.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.3.1

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.

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
