boot: zephyr: Do not use `irq_lock()` if using arm cleanup

`irq_lock()` sets `BASEPRI_MAX` aka. the `BASEPRI` mask to whatever
zephyr has configured it to be by the value of `_EXC_IRQ_DEFAULT_PRIO`.

However by calling arm_cleanup() we also do the call to
`__disable_irq()` setting the PRIMASK to 1. Meaning the only exceptions
we can recive is fault exceptions. Masking out more exceptions does not
really make sense.

Sometimes applications booted by MCUBoot will not expect the `BASEPRI`
to be set to something else than 0(No effect). Meaning if they depend on
using some exception which now is masked out by `BASEPRI` they will
fail.

mcuboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is mcuboot version 1.8.0-dev

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
