Use same format for scratch and slot trailer

Prior to this change, the scratch image trailer had a different format
from a slot image trailer.  Specifically:

1. The scratch trailer only contained a single set of status entries
   (three bytes); the slot trailer contained `BOOT_STATUS_MAX_ENTRIES`
   sets of status entries.

2. The scratch trailer did not contain the `copy_done` field.

This inconsistency required some extra conditional logic in the trailer
handling code.  It is simpler to just use the same trailer format
everywhere.

This commit removes this inconsistency.  Now, the scratch trailer
structure is identical to that of the slot trailer.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.3.0

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
