Zephyr v2.3.0

We are pleased to announce the release of Zephyr RTOS version 2.3.0.

Major enhancements with this release include:

• A new Zephyr CMake package has been introduced, reducing the need for
  environment variables
• A new Devicetree API, based on hierarchical macros, has been introduced. This
  new API allows the C code to access virtually all nodes and properties in a
  clean, organized fashion
• The kernel timeout API has been overhauled to be flexible and configurable,
  with future support for features like 64-bit and absolute timeouts in mind
• A new k_heap/sys_heap heap allocator has been introduced, with much better
  performance than the existing k_mem_pool/sys_mem_pool
• Zephyr now integrates with the TF-M (Trusted Firmware M) PSA-compliant
  framework
• The Bluetooth Low Energy Host now supports LE Advertising Extensions
• The CMSIS-DSP library is now included and integrated

The following sections provide detailed lists of changes by component.

Known issues

You can check all currently known issues by listing them using the GitHub
interface and listing all issues with the bug label.

A single high-priority bug is currently open:

• #23364 - Bluetooth: bt_recv deadlock on supervision timeout with
  pending GATT Write Commands

API Changes

• HWINFO

  • The identifier data structure for hwinfo drivers is clarified. Drivers are
    responsible for ensuring that the identifier data structure is a sequence
    of bytes. The returned ID value is not supposed to be interpreted based on
    vendor-specific assumptions of byte order and should express the identifier
    as a raw byte sequence.
    The changes have an impact on users that use the hwinfo API to identify
    their devices.
    The sam0 driver byte swaps each 32 bit word of the 128 bit identifier to
    big endian.
    The nordic driver byte swaps the entire 64 bit word to big endian.

• I2C

  • Added a new API for recovering an I2C bus from situations where the I2C
    master and one or more I2C slaves are out of synchronization (e.g. if the
    I2C master was reset in the middle of an I2C transaction or if a noise
    pulse was induced on the SCL line).

Deprecated in this release

• Kernel

  • k_uptime_delta_32(), use k_uptime_delta()

  • Timeout values

    • All timeout values are now encapsulated k_timeout_t opaque structure when
      passing them to the kernel. If you want to revert to the previous s32_t
      type for the timeout parameter, please enable
      :option:CONFIG_LEGACY_TIMEOUT_API

• Bluetooth

  • BT_LE_SCAN_FILTER_DUPLICATE, use BT_LE_SCAN_OPT_FILTER_DUPLICATE instead
  • BT_LE_SCAN_FILTER_WHITELIST, use BT_LE_SCAN_OPT_FILTER_WHITELIST instead
  • bt_le_scan_param::filter_dup, use bt_le_scan_param::options instead
  • bt_conn_create_le(), use bt_conn_le_create() instead
  • bt_conn_create_auto_le(), use bt_conn_le_create_auto() instead
  • bt_conn_create_slave_le(), use bt_le_adv_start() instead with
    bt_le_adv_param::peer set to the remote peers address.
  • BT_LE_ADV_* macros, use BT_GAP_ADV_* enums instead

• Boards

  • nrf51_pca10028 has been renamed to nrf51dk_nrf51422
  • nrf51_pca10031 has been renamed to nrf51dongle_nrf51422
  • nrf52810_pca10040 has been renamed to nrf52dk_nrf52810
  • nrf52_pca10040 has been renamed to nrf52dk_nrf52832
  • nrf52833_pca10100 has been renamed to nrf52833dk_nrf52833
  • nrf52811_pca10056 has been renamed to nrf52840dk_nrf52811
  • nrf52840_pca10056 has been renamed to nrf52840dk_nrf52840
  • nrf52840_pca10059 has been renamed to nrf52840dongle_nrf52840
  • nrf9160_pca10090 has been renamed to nrf9160dk_nrf9160
  • nrf52840_pca10090 has been renamed to nrf9160dk_nrf52840
  • nrf52_pca20020 has been renamed to thingy52_nrf52832
  • nrf5340_dk_nrf5340 has been renamed to nrf5340pdk_nrf5340
  • efr32_slwstk6061a has been renamed to efr32_radio_brd4250b

• Devicetree

  • The C macros generated from the devicetree in previous releases are now
    deprecated in favor of a new <devicetree.h> API.
  • See :ref:dt-from-c for a high-level guide to the new API, and
    :ref:devicetree_api for an API reference.
  • Use of the legacy macros now requires explicitly enabling
    :option:CONFIG_LEGACY_DEVICETREE_MACROS. See :ref:dt-legacy-macros for
    more information, including a link to a migration guide to the new API.

• Other

  • MACRO_MAP has been deprecated. Use FOR_EACH instead.
  • BUILD_ASSERT_MSG has been deprecated. Use BUILD_ASSERT instead.

Removed APIs in this release

• The INLINE macro in util.h has been removed.
• STACK_ANALYZE, stack_analyze and stack_unused_space_get have been
  removed.

Stable API changes in this release

• Bluetooth Mesh

  • The net_idx parameter has been removed from the Health Client model
    APIs since it can be derived (by the stack) from the app_idx parameter

• Networking

  • The NET_DEVICE_INIT(), NET_DEVICE_INIT_INSTANCE(), NET_DEVICE_OFFLOAD_INIT()
    and ETH_NET_DEVICE_INIT() macros changed and take a device power management
    function pointer parameter. If networking PM is not implemented for the
    specific network device, the device_pm_control_nop value can be used.

• Video

  • The video_dequeue() API call now takes a k_timeout_t for the timeout
    parameter. This reverts to s32_t if CONFIG_LEGACY_TIMEOUT_API is enabled.

• Floating Point Services

  • FLOAT and FP_SHARING Kconfig options have been renamed to FPU and FPU_SHARING,
    respectively.

Kernel

• A new general purpose memory allocator, sys_heap/k_heap, has been added
  to Zephyr with more conventional API/behavior, better space
  efficiency and higher performance than the pre-existing mem_pool.
  The older mem_pool APIs are, by default, wrappers around this new
  heap backend and will be deprecated in an upcoming release. The
  original implementation remains available for this release via
  disabling CONFIG_MEM_POOL_HEAP_BACKEND.
• The timeout arguments to all kernel calls are now a "k_timeout_t"
  type instead of a 32 bit millisecond count. These can be
  initialized in arbitrary time units (ns/us/ms, ticks), be
  interpreted relative to either current time or system start, and be
  expressed in 64 bit quantities. This involves a minor change to the
  API, so the original API is still available in a completely
  source-compatible way via CONFIG_LEGACY_TIMEOUT_API.
• Simplified dummy thread implementation and properly name idle threads
• Centralized new thread priority check
• Refactored device structures and introduced struct init_entry which is
  a generic init end-point. SYS_INIT() generates only a struct init_entry via
  calling INIT_ENTRY_DEFINE(). Also removed struct deviceconfig leaving
  struct device to own everything now.

Architectures

• ARC:

  • Changed to automatic generation of privilege stack for ARC MPU V2 to
    avoid the potential waste of memory When USERSPACE is configured
  • Enhanced runtime programming for the MPU v3 by making the gap-filling
    of kernel memory a user-configurable feature
  • Refactored the thread switch code in epilogue of irq and exception
  • Refactored the assembly codes for better maintenance
  • Fixed the behavior of ARC timer driver
  • Fixed the behavior of ARC SMP
  • Fixed the wrong configurations of ARC boards in Kconfig and DTS

• ARM:

  • CMSIS has been moved out of the main tree and now resides in its
    own standalone module repository
  • Updated CMSIS version to 5.7.0
  • Added CMSIS-DSP library integration
  • Added semihosting console support
  • Cleanups and improvements to the Cortex-M exception vector table
  • Fixed the behavior of Cortex-M spurious IRQ handler
  • Fixed parsing of Cortex-M MemManage Stacking Errors
  • Fixed the arch_cpu_idle() implementation for Cortex-M and Cortex-R
  • Renamed Cortex-R architecture port to cortex_a_r in preparation for the
    AArch32 Cortex-A architecture port
  • Added processor exception handling and reporting framework for Cortex-R
  • Added nested interrupt support on AArch32 Cortex-R and AArch64 Cortex-A
  • Refactored Cortex-R interrupt system to remove fake multi-level interrupt
    controller abstraction scheme

• POSIX:

  • Added support for building on ARM hosts

• RISC-V:

  • Added support for hard floating point for RISC-V
  • Added march and mabi options to Kconfig
  • Fixed compilation warning for platforms without PLIC

• x86:

  • Instrumented code for timing information
  • Added ability for SoC to add MMU regions
  • x86 FPU sharing symbols renam...

Zephyr 2.2.0

We are pleased to announce the release of Zephyr RTOS version 2.2.0.

Major enhancements with this release include:

• Initial support for the 64-bit ARMv8-A architecture (Experimental).
• CANopen protocol support through 3rd party CANopenNode stack
• LoRa support was added through integration of the Semtech LoRaWAN endpoint
  stack and addition of a new SX1276 LoRa modem driver
• A new and redesigned GPIO API has been introduced, and all in-tree users have been ported to it

The following sections provide detailed lists of changes by component.

API Changes

Deprecated in this release

• Settings

  • SETTINGS_USE_BASE64, encoding values in base64 is marked for removal.

Stable API changes in this release

• GPIO

  • GPIO API has been reworked to support flags known from Linux DTS GPIO
    bindings. They will typically be defined in the board DTS file

    • GPIO_ACTIVE_LOW, GPIO_ACTIVE_HIGH used to set pin active level
    • GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE used to configure pin as open drain or
      open source
    • GPIO_PULL_UP, GPIO_PULL_DOWN used to configure pin bias

  • Reading / writing of pin logical level is supported by gpio_pin_get,
    gpio_pin_set functions.

  • Reading / writing of pin physical level is supported by gpio_pin_get_raw,
    gpio_pin_set_raw functions.

  • New set of port functions that operate simultaneously on multiple pins
    that belong to the same controller.

  • Interrupts should be configured by a dedicated
    gpio_pin_interrupt_configure() function. Configuring interrupts via
    gpio_pin_configure() is still supported but this feature will be removed
    in future releases.

  • New set of flags allows to set arbitrary interrupt configuration (if
    supported by the driver) based on pin physical or logical levels.

  • New set of flags to configure pin as input, output or in/out as well as set
    output initial state.

  • Majority of the old GPIO API has been deprecated. While the care was taken
    to preserve backward compatibility due to the scope of the work it was not
    possible to fully achieve this goal. We recommend to switch to the new GPIO
    API as soon as possible.

  • Areas where the deprecated API may behave differently to the original old
    implementation are:

    • Configuration of pin interrupts, especially involving GPIO_INT_ACTIVE_LOW
      and GPIO_POL_INV flags.
    • Behavior of gpio_pin_configure() when invoked without interrupt related
      flags. In the new implementation of this deprecated functionality the
      interrupts remain unmodified. In the original implementation some of the
      GPIO drivers would disable the interrupts.

  • Several drivers that rely on the functionality provided by the GPIO API
    were reworked to honor pin active level. Any external users of these
    drivers will have to update their DTS board files.

    • bluetooth/hci/spi.c
    • display/display_ili9340.c
    • display/ssd1306.c
    • ieee802154/ieee802154_mcr20a.c
    • ieee802154/ieee802154_rf2xx.c
    • lora/sx1276.c
    • wifi/eswifi/eswifi_core.c
    • majority of the sensor drivers

• PWM

  • The pwm_pin_set_cycles(), pwm_pin_set_usec(), and
    pwm_pin_set_nsec() functions now take a flags parameter. The newly
    introduced flags are PWM_POLARITY_NORMAL and PWM_POLARITY_INVERTED
    for specifying the polarity of the PWM signal. The flags parameter
    can be set to 0 if no flags are required (the default is
    PWM_POLARITY_NORMAL).
  • Similarly, the pwm_pin_set_t PWM driver API function function now
    takes a flags parameter. The PWM controller driver must check the
    value of the flags parameter and return -ENOTSUP if any
    unsupported flag is set.

• USB

  • The usb_enable() function, which was previously invoked automatically
    by the USB stack, now needs to be explicitly called by the application
    in order to enable the USB subsystem.
  • The usb_enable() function now takes a parameter, usb_dc_status_callback
    which can be set by the application to a callback to receive status events
    from the USB stack. The parameter can also be set to NULL if no callback is required.

• nRF flash driver

  • The nRF Flash driver has changed its default write block size to 32-bit
    aligned. Previous emulation of 8-bit write block size can be selected using
    the CONFIG_SOC_FLASH_NRF_EMULATE_ONE_BYTE_WRITE_ACCESS Kconfig option.
    Usage of 8-bit write block size emulation is only recommended for
    compatibility with older storage contents.

• Clock control

  • The callback prototype (clock_control_cb_t) has now additional argument
    (clock_control_subsys_t) indicating which clock subsystem got started.

Removed APIs in this release

• Shell

  • SHELL_CREATE_STATIC_SUBCMD_SET (deprecated), replaced by
    SHELL_STATIC_SUBCMD_SET_CREATE
  • SHELL_CREATE_DYNAMIC_CMD (deprecated), replaced by SHELL_DYNAMIC_CMD_CREATE

• Newtron Flash File System (NFFS) was removed. NFFS was removed since it has
  serious issues, not fixed since a long time. Where it was possible
  NFFS usage was replaced by LittleFS usage as the better substitute.

Kernel

• Addressed some race conditions observed on SMP-enabled systems
• Propagate a distinct error code if a workqueue item is submitted that
  has already been completed
• Disable preemption when handing fatal errors
• Fix an issue with the sytsem call stack frame if the system call is
  preempted and then later tries to Z_OOPS()
• add k_thread_stack_space_get() system call for analyzing thread stack
  space. Older methods which had problems in some cases or on some
  architectures like STACK_ANALYZE() are now deprecated.
• Many kernel object APIs now optionally return runtime error values
  instead of relying on assertions. Whether these return values, fail
  assertions, or do no checking at all is controlled by the new
  Kconfig options ASSERT_ON_ERRORS, NO_RUNTIME_CHECKS, RUNTIME_ERROR_CHECKS.
• Cleanups to the arch_cpu_start() API
• Spinlock validation now dumps the address of the incorrectly used spinlock
• Various improvements to the assertion mechanism
• k_poll() may be passed 0 events, in which case it just puts the caller to
  sleep
• Add k_thread_foreach_unlocked() API
• Add an assertion if k_sleep() is called from an ISR
• Numerous 64-bit fixes, mostly related to data type sizes
• k_mutex_unlock() is now correctly a rescheduling point
• Calling k_thread_suspend() on the current thread now correctly invokes
  the scheduler
• Calling k_thread_suspend() on any thread cancels any pending timeouts for
  that thread
• Fix edge case in meta-IRQ preemption of co-operative threads
