imgtool: Adjust base_addr when injecting header

If adding a header to a .hex file (using the command line
"--pad-header"), the hex file gets shifted by header size. This may
cause hard coded addresses to be off by "header-size", making the
firmware unusable. Instead, adjust the base address by the header
size, so the existing firmware in the hex file is loaded to the
proper addresses.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 1.2.0

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 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
