Zephyr 2.5.0 (Working Draft)¶
We are pleased to announce the release of Zephyr RTOS version 2.5.0.
Major enhancements with this release include:
The following sections provide detailed lists of changes by component.
You can check all currently known issues by listing them using the GitHub interface and listing all issues with the bug label.
Removed SETTINGS_USE_BASE64 support as its been deprecated for more than two releases.
lwm2m_rd_client_start()function now accepts an additional
flagsparameter, which allows to configure current LwM2M client session, for instance enable bootstrap procedure in the curent session.
Changed vcnl4040 dts binding default for property ‘proximity-trigger’. Changed the default to match the HW POR state for this property.
clock_control_async_on()function will now take
user_dataas arguments instead of structure which contained list node, callback and user data.
Deprecated in this release¶
ARM Musca-A board and SoC support deprecated and planned to be removed in 2.6.0.
Removed APIs in this release¶
Stable API changes in this release¶
Boards & SoC Support¶
Added support for these SoC series:
Made these changes in other SoC series:
Changes for ARC boards:
Added support for these ARM boards:
Made these changes in other boards:
Added support for these following shields:
Drivers and Sensors¶
BLE split software Controller
Build and Infrastructure¶
Improved support for additional toolchains:
DT_ENUM_IDX_OR: new macro
Support for legacy devicetree macros via
CONFIG_LEGACY_DEVICETREE_MACROSwas removed. All devicetree-based code should be using the new devicetree API introduced in Zephyr 2.3 and documented in Devicetree access from C/C++. Information on flash partitions has moved to Flash map.
Libraries / Subsystems¶
HALs are now moved out of the main tree as external modules and reside in their own standalone repositories.
Added hardening against hardware level fault injection and timing attacks, see
CONFIG_BOOT_FIH_PROFILE_HIGHand similar kconfig options.
Introduced Abstract crypto primitives to simplify porting.
Added ram-load upgrade mode (not enabled for zephy-rtos yet).
Renamed single-image mode to single-slot mode, see
Added patch for turning off cache for Cortex M7 before chain-loading.
Fixed boostrapping in swap-move mode.
Fixed issue causing that interrupted swap-move operation might brick device if the primary image was padded.
Fixed issue causing that HW stack protection catches the chain-loaded application during its early ini, by disableing HW stack protection (temporary hack).
Added reset of Cortex SPLIM registers before boot.
Fixesd build issue that occurs if CONF_FILE contains multiple file paths instead of single file path.
Print image digest during verify.
Add possibility to set confirm flag for hex files as well.
Usage of –confirm implies –pad.
Fixed ‘custom_tlvs’ argument handling.
