Test erased flash with "flash_area_read_is_empty()"

Mynewt has recently added an encrypted flash layer driver, that runs
transparently on any flash, handling reads and writes, and bypassing
other flash operations to the HW driver. As a result of this change,
checking for erased data cannot be done by read + compare to erased_val
but need to be routed to an empty check on the lower level. To do this
Mynewt added a new flash_map function called "flash_area_read_is_empty"
which checks for erased blocks (and reads/decrypts the data as well).

This commit uses `flash_area_read_is_empty` to determine if magic,
flags and swap status are erased. For Zephyr/sim commits were added
previously that mimic this functionality by simply doing the
read/compare.

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
