Define the load_addr header field

Add a flag `IMAGE_F_RAM_LOAD` and an associated header field
`ih_load_addr` to indicate that a particular image should be loaded into
RAM instead of being executed directly out of flash.  If the flag is not
set, this field will be ignored.  If it is set, and this feature is
supported by the bootloader, the image will be loaded into RAM at the
address specified in the new header field.

None of this functionality is implemented at this time.  This is merely
to define the header format to avoid having to change the image format
later.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot, version 0.9.0

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.

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
