Zephyr microPlatform

Summary

MCUboot history was rewritten following v1.1.0 release. Zephyr integrates OpenThread support, and has the usual set of incompatible changes.

Highlights

  • Non-fast-forward update for MCUboot onto the post-v1.1.0 development branch
  • Zephyr updates from the 1.11 development branch

Components

MCUboot

Features

Flash mass erase:
  • MCUboot's build system now tries to mass-erase the flash device when the board runner supports it. This ensures a consistent initial state. It can be disabled using the CONF_ZEPHYR_TRY_MASS_ERASE bootloader configuration option.

Bugs

Zephyr workaround for FLASH_DRIVER_NAME rename:
  • The Zephyr port has a shim to work around a rename of FLASH_DRIVER_NAME to FLASH_DEV_NAME upstream.
Documentation fixes:
  • Various documentation fixes were merged. The documentation was rewritten as markdown, and all moved to docs/.
Zephyr usability fixes:
  • Numerous bug fixes and usability improvements were merged for the Zephyr port.

Zephyr

Features

OpenThread support with 802.15.4 improvements:
  • OpenThread support was merged into Zephyr, along with support for the 802.15.4 radio layer. This affects the L3 and L2 layers of the Zephyr networking stack as well.
DTC_OVERLAY_FILE now accepts a list:
  • Multiple device tree overlay files are now supported by setting DTC_OVERLAY_FILE to a whitespace-separated list of files to use. This is analogous to how CONF_FILE works. The file dts.overlay in the application directory will be used by default if it is present and DTC_OVERLAY_FILE is not defined.
DTC_OVERLAY_DIR removed:
  • The old DTC_OVERLAY_DIR variable is no longer supported; applications should update to use DTC_OVERLAY_FILE only.
FLASH_DRIVER_NAME renamed to FLASH_DEV_NAME:
  • The old FLASH_DRIVER_NAME was removed. Applications should use FLASH_DEV_NAME. MCUboot has been updated to reflect this change.
Legacy HTTP removed upstream:
  • The legacy HTTP API has been removed, but the commit with this support has serious problems, as detailed in the following issue.

https://github.com/zephyrproject-rtos/zephyr/issues/6010

The OSF tree has temporarily reverted this commit; we are working with upstream on a better solution.

Humidity sensor channel units redefined:
  • The humidity sensor channel units were redefined to percents, not milli-percents. Applications using this API will need to update to the new unit.
GET_DISK_SIZE ioctl removed:
  • The filesystem GET_DISK_SIZE IOCTL was removed.
Bluetooth refactoring continues:
  • The Bluetooth controller core continues to be cleaned up and refactored as part of a sequence of general improvements.

Various Bluetooth APIs were renamed from the radio* to the ll* namespace.

ARM CMSIS headers updated:
  • ARM CMSIS headers were updated to version 5.2.0.
New sensor channels:
  • New sensor channels were added for CO2, VOC, voltage, and current, along with support for the CCS811 gas sensor device.
POSIX interaction with stdin:
  • The native POSIX target now supports console interaction with stdin.
External mbedTLS support:
  • It is now possible to use an external mbedtls implementation. Applications interested in taking advantage of this should refer to the help for CONFIG_MBEDTLS_LIBRARY.
USB HID support:
  • The USB subsystem now includes an HID class and sample application demonstrating its functionality.
IPv6 improvements:
  • IPv6 neighbor addition and deletion is now supported. Network interfaces using IPv6 can now route packets between themselves.
Flashing for JLink boards:
  • Boards using JLink can now be flashed using the build system flash target.
New STM32 features:
  • SPI support was added for STM32F1 targets.

STM32F072 SoC support added as well as board configurations for STM32F072-EVAL and STM32F072B-DISCO.

I2C support was added to the nucleo_f411re and for nucleo_f429zi boards.

ST vl53l0x time of flight sensor:
  • Added support for the ST vl53l0x time of flight sensor. This included an import of the official ST library supporting the vl53l0x.
DFU/mcuboot subsystem improvements:
  • The DFU subsystem received miscellaneous improvements, as well as additional APIs useful for targets built for chain-loading by MCUboot.
PCI enumberation for Atom-based targets:
  • Atom-based targets now support enumerating PCI devices.
erase-block-size property for DTS flash nodes:
  • The DTS flash bindings now support an optional erase- block-size property.
Flash page layout support for NXP devices:
  • NXP-based devices use newly updated flash DTS bindings to support the flash page layout APIs, which improves their MCUboot support and eliminates compiler warnings when building MCUboot on those targets
DTS sensor nodes for NXP boards:
  • Various DTS nodes and fixup files were added for sensor nodes on NXP boards.
Pinux for Atmel SAM0:
  • SAM0 based devices now have a pinmux driver.
New kconfig options for controlling optimization:
  • A new CONFIG_NO_OPTIMIZATIONS flag allows users to control the optimization level with GCC compatible compilers with a single switch, among other optimization level changes.
NXP LPC SoC family support:
  • Add Zephyr support for NXP's LPC SoC family. Including an initial import of the device header and driver files for lpc54114 from mcux 2.2.1. The first board supported is the lpcxpresso54114. Shim drivers were also introduced for pinmux, GPIO and USART.
Emulated vector table relocation for M0 targets:
  • For ARM Cortex M0 targets, support was added for a software relay table for interrupt handling. This allows runtime changes to IRQ handler routines on these targets, which do not have hardware support for relocating the vector table. This is a prerequisite for enabling MCUboot support on these targets.
Support for M0 targets with hardware vector table relocation:
  • Additional support for M0 targets which do support hardware vector table relocation, such as STM32F0, was also added.
SoC-level device tree fixup files:
  • Add support for SoC family level fixup files. This should remove the need for several duplicated fixup files at the board level.
Runtime for simulated nRF52 devices:
  • Zephyr now supports running simulated nRF52 hardware.
Nordic HAL updates:
  • Replace the Nordic HAL and MDK with the nrfx extract based on the nRF5 SDK 0.8.0.
abs function added to Zephyr minimal libc:
  • Added abs function to minimal libc implementation.
New kconfig option for enabling MCUboot support:
  • Added the BOOTLOADER_MCUBOOT config to make the resulting image bootable by the MCUboot open source bootloader. Currently, this includes the text section offset and the vector relay table for Cortex-M0.
New DTS bindings:
  • In device tree, YAML bindings were added for SPI devices, bluetooth modules, and SPI bluetooth modules. Support was also added for flash controller nodes on STM32 targets. Applications may also now add their own dts.fixup files. All x86 targets now support device tree.
Console harness support for samples:
  • Various samples now support a console harness, which can be used to evaluate whether their console output matches expectated values.

Bugs

Ninja fixes for flashing and debugging:
  • The flash, debug, and debugserver targets now properly interact with the console when Ninja is used instead of Make. This is an important fix for users who have multiple boards using the same flash or debug backend.
Hackaround for flash write protection on NXP mcux devices:
  • A hacky fix for a missing write protection implementation was merged for the mcux flash driver, which allows it to interoperate with the DFU subsystem for MCUboot.
LWM2M fixes:
  • The LWM2M subsystem received four fixes.
Networking fixes:
  • Seven other fixes were merged to the networking subsystem, mostly related to RPL.
Build break fixed on ARM with userspace enabled:
  • The build was fixed on ARM if user space support was selected.
Native target fixes for code coverage testing:
  • The native target saw several bug fixes, excluding unlikely or unreachable code from the coverage reports.
Core Bluetooth fixes:
  • The core Bluetooth controller saw several fixes for edge cases. It continues to pass conformance tests.

Various tweaks and refactoring patches were merged into the Bluetooth subsystem, including timing adjustments for nRF52840-DK, support for non- connectable builds, and separation of some Nordic- specific code from the core into the HAL.

Bluetooth Mesh fixes:
  • Bluetooth Mesh saw five fixes related to SeqAuth values, timeout calculations, CID passing, and Kconfig documentation.
Documentation spelling fixes:
  • Various spelling fixes throughout the documentation were merged.
