microPlatform update 35

November 29, 2018

Summary

Zephyr microPlatform changes for 35

A very active snapshot from Zephyr as part of the v1.14 development cycle. Tree-wide refactoring for DTS, board.h include removal and more logging changes. MCUboot and sample applications updated as a result.

Linux microPlatform changes for 35

Core layer updates based on the latest OE/Yocto master changes.

Zephyr microPlatform

Highlights

  • Zephyr v1.14 development snapshot with tree-wide refactoring
  • MCUboot merge from JuulLabs-OSS with updates due to upstream Zephyr changes
  • Sample applications get some updates due to upstream Zephyr changes

Components

MCUboot

Features

MbedTLS changes to support versions > 2.6.1

RSA image handling was changed so that MbedTLS versions greater than 2.6.1 would be compatible.

Bugs

Zephyr build fixed due to DTS changes

Due to Zephyr upstream changing the way dts_fixup.h defines the fixup definitions, MCUboot needed a patch to alter FLASH_DEV_NAME -> DT_FLASH_DEV_NAME.

Zephyr

Features

Several tree wide-patches hit this merge-up, and the first is a refactoring of all dtsfixup defines which pretended to be Kconfig settings due to their naming of CONFIG. This was causing some confusion when attempting to figure out where various settings were generated. Instead of CONFIG_, all of these settings are now generated as DT_*. Enter quite a few patches and follow-up cleanup patches to make all of this happen.

Refactor LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros

The LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros now take log level as optional parameter. LOG_MODULE_DECLARE can now also be used in static inline functions in headers. This was another tree-wide set of patches which affected every file with Logger configuration.

Remove board.h from boards that don’t need it

Last of the tree-wide patches that might might affect external code, was a removal of unneeded board.h files. These typically only included . If you see a “file not found: board.h” error during your next compile, hopefully you’ll remember what you saw here and just remove the offending “#include ” and replace it with “#include ” if needed.

Dynamic interrupt API for the kernel

Zephyr wants to support hypervisor applications such as ACRN which presents virtual devices via PCI enumeration. In this case, the interrupt configuration is not known at build time. To support this and other use-cases, dynamic interrupt APIs were added to the kernel.

Additional SoC and board support

The STM32F143xG SoC and ST B-L072Z-LRWAN1 board were added to to Zephyr.

Bugs

Scheduler race condition fixed in k_sched_time_slice_set()

If k_sched_time_slice_set() was interrupted by a timeslice event, the slicing state could be corrupted. Fixed by using the existing lock sched_lock around the operations.

Fix DTS fixup file location for external SoCs

If you were wondering why the dts_fixup.h file in your external SoC wasn’t automatically being included like the dts_fixup.h files in the SoCs inside Zephyr, then wonder no more! It was a bug. And now it’s fixed.

hawkBit and MQTT sample application

Features

Not addressed in this update

Bugs

DT_* prefix naming update

This affected some FLASH_DEV_NAME references in our sample.

Remove board.h references

Upstream Zephyr removed the board.h file for many boards that didn’t actually need them. In our case, we need to remove the left-over board.h references in our samples.

LWM2M sample application

Features

Bugs

DT_* prefix naming update

This affected some FLASH_DEV_NAME references in our sample.

Remove board.h references

Upstream Zephyr removed the board.h file for many boards that didn’t actually need them. In our case, we need to remove the left-over board.h references in our samples.

Fix WNC-M14A2A modem support

Upstream Zephyr is moving all of the generic settings belonging to “shield” type hardware out of the board and SoC files. This eliminates copy/paste errors as well as duplicated settings. Instead, these should be configured as Zephyr “shields” which have their own directory and settings per board. However, the WNC-M14A2A cannot be configured just yet as a shield due to on-going discussion regarding exposure of GPIO pins in a standard way. So the settings were all moved to the upstream LwM2M client sample for now.

Following along with that change, we’ve introduced the same files to the Foundries.io LwM2M sample so that the modem functionality is not lost.
