zephyr: Kconfig: change default for MCUBOOT_CLEANUP_ARM_CODE

Zephyr has introduced an option to perform the cleanup
of ARM core HW registers during early boot, when the
firmware is chain-loaded by MCUboot. Therefore, MCUboot
does not need to perform the same cleanup before jumping
to the application image. The patch relies on the fact
that building MCUboot with Zephyr implies loading also
a Zephyr-based application firmware. If this is not the
case, the application developer needs to enable the
MCUBOOT_CLEANUP_ARM_CODE Kconfig option manually, in the
project configuration.

mcuboot

Coverity Scan Build Status Build/Test

This is mcuboot version 1.6.0

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 simple software upgrades.

MCUboot is operating system and hardware independent and relies on hardware porting layers from the operating. 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

Joining

Developers welcome!
