API Changes

Changes in this release

• Zephyr now requires Python 3.8 or higher

• Changed spi_cs_control to remove anonymous struct. This causes possible breakage for static initialization of the struct. Updated SPI_CS_CONTROL_PTR_DT to reflect this change.

• The CONFIG_LEGACY_INCLUDE_PATH option has been disabled by default, all upstream code and modules have been converted to use <zephyr/...> header paths. The option is still available to facilitate the migration of external applications, but will be removed with the 3.4 release. The scripts/utils/migrate_includes.py script is provided to automate the migration.

• include/zephyr/zephyr.h no longer defines __ZEPHYR__. This definition can be used by third-party code to compile code conditional to Zephyr. The definition is already injected by the Zephyr build system. Therefore, any third-party code integrated using the Zephyr build system will require no changes. External build systems will need to inject the definition by themselves, if they did not already.

• include/zephyr/zephyr.h has been deprecated in favor of include/zephyr/kernel.h, since it only included that header. No changes are required by applications other than replacing #include <zephyr/zephyr.h> with #include <zephyr/kernel.h>.

• Bluetooth: Applications where CONFIG_BT_EATT is enabled must set the chan_opt field on the GATT parameter structs. To keep the old behavior use BT_ATT_CHAN_OPT_NONE.

• CAN

  • The Zephyr SocketCAN definitions have been moved from include/zephyr/drivers/can.h to include/zephyr/net/socketcan.h, the SocketCAN struct can_frame has been renamed to socketcan_frame, and the SocketCAN struct can_filter has been renamed to socketcan_filter. The SocketCAN utility functions are now available in include/zephyr/net/socketcan_utils.h.

  • The CAN controller struct zcan_frame has been renamed to can_frame, and struct zcan_filter has been renamed to can_filter.

  • The can_state enumerations have been renamed to contain the word STATE in order to make their context more clear:

    • CAN_ERROR_ACTIVE renamed to CAN_STATE_ERROR_ACTIVE.

    • CAN_ERROR_WARNING renamed to CAN_STATE_ERROR_WARNING.

    • CAN_ERROR_PASSIVE renamed to CAN_STATE_ERROR_PASSIVE.

    • CAN_BUS_OFF renamed to CAN_STATE_BUS_OFF.

  • The error code for can_send() when the CAN controller is in bus off state has been changed from -ENETDOWN to -ENETUNREACH. A return value of -ENETDOWN now indicates that the CAN controller is in CAN_STATE_STOPPED.

  • The list of valid return values for the CAN timing calculation functions have been expanded to allow distinguishing between an out of range bitrate/sample point, an unsupported bitrate, and a resulting sample point outside the guard limit.

• Memory Management Drivers

  • Added sys_mm_drv_update_page_flags() and sys_mm_drv_update_region_flags() to update flags associated with memory pages and regions.

Removed APIs in this release

• The following functions, macros, and structures related to the deprecated kernel work queue API have been removed:

• Removed deprecated civetweb module and the associated support code and samples.

Deprecated in this release

• DT_SPI_DEV_CS_GPIOS_LABEL and DT_INST_SPI_DEV_CS_GPIOS_LABEL are deprecated in favor of utilizing DT_SPI_DEV_CS_GPIOS_CTLR and variants.

• DT_GPIO_LABEL, DT_INST_GPIO_LABEL, DT_GPIO_LABEL_BY_IDX, and DT_INST_GPIO_LABEL_BY_IDX, are deprecated in favor of utilizing DT_GPIO_CTLR and variants.

• DT_LABEL, and DT_INST_LABEL, are deprecated in favor of utilizing DT_PROP and variants.

• DT_BUS_LABEL, and DT_INST_BUS_LABEL, are deprecated in favor of utilizing DT_BUS and variants.

• STM32 LPTIM domain clock should now be configured using devicetree. Related Kconfig CONFIG_STM32_LPTIM_CLOCK option is now deprecated.

• label property from devicetree as a base property. The property is still valid for specific bindings to specify like gpio-leds and fixed-partitions.

• Bluetooth mesh Configuration Client API prefixed with bt_mesh_cfg_ is deprecated in favor of a new API with prefix bt_mesh_cfg_cli_.

• Pinmux API is now officially deprecated in favor of the pin control API. Its removal is scheduled for the 3.4 release. Refer to Pin Control for more details on pin control.

• Flash Map API macros FLASH_MAP_, which have been using DTS node label property to reference partitions, have been deprecated and replaced with FIXED_PARTITION_ whch use DTS node label instead. Replacement list:

  Deprecated, takes label property	Replacement, takes DTS node label
  FLASH_AREA_ID	FIXED_PARTITION_ID
  FLASH_AREA_OFFSET	FIXED_PARTITION_OFFSET
  FLASH_AREA_SIZE	FIXED_PARTITION_SIZE
  FLASH_AREA_LABEL_EXISTS	FIXED_PARTITION_EXISTS
  FLASH_AREA_DEVICE	FIXED_PARTITION_DEVICE

  FLASH_AREA_LABEL_STR is deprecated with no replacement as its sole purpose was to obtain the DTS node property label.

Devicetree

• Use of the devicetree label property has been deprecated, and the property has been made optional in almost all bindings throughout the tree.

  In previous versions of zephyr, label properties like this commonly appeared in devicetree files:

  foo {
          label = "FOO";
          /* ... */
  };
  

  You could then use something like the following to retrieve a device structure for use in the Device Driver Model:

  const struct device *my_dev = device_get_binding("FOO");
  if (my_dev == NULL) {
          /* either device initialization failed, or no such device */
  } else {
          /* device is ready for use */
  }
  

  This approach has multiple problems.

  First, it incurs a runtime string comparison over all devices in the system to look up each device, which is inefficient since devices are statically allocated and known at build time. Second, missing devices due to misconfigured device drivers could not easily be distinguished from device initialization failures, since both produced NULL return values from device_get_binding(). This led to frequent confusion. Third, the distinction between the label property and devicetree node labels – which are different despite the similar terms – was a frequent source of user confusion, especially since either one can be used to retrieve device structures.

  Instead of using label properties, you should now generally be using node labels to retrieve devices instead. Node labels look like the lbl token in the following devicetree:

  lbl: foo {
          /* ... */
  };
  

  and you can retrieve the device structure pointer like this:

  /* If the next line causes a build error, then there
   * is no such device. Either fix your devicetree or make sure your
   * device driver is allocating a device. */
  const struct device *my_dev = DEVICE_DT_GET(DT_NODELABEL(lbl));
  
  if (!device_is_ready(my_dev)) {
          /* device exists, but it failed to initialize */
  } else {
          /* device is ready for use */
  }
  

  As shown in the above snippet, DEVICE_DT_GET should generally be used instead of device_get_binding() when getting device structures from devicetree nodes. Note that you can pass DEVICE_DT_GET any devicetree node identifier – you don’t have to use DT_NODELABEL, though it is usually convenient to do so.

• Support for devicetree “fixups” was removed. For more details, see commit b2520b09a7

• Devicetree API

  • All devicetree macros now recursively expand their arguments. This means that in the following example, INDEX is always replaced with the number 3 for any hypothetical devicetree macro DT_FOO():

    #define INDEX 3
    int foo = DT_FOO(..., INDEX)
    

    Previously, devicetree macro arguments were expanded or not on a case-by-case basis. The current behavior ensures you can always rely on macro expansion when using devicetree APIs.

  • New API macros:

    • DT_FIXED_PARTITION_EXISTS

    • DT_FOREACH_CHILD_SEP_VARGS

    • DT_FOREACH_CHILD_SEP

    • DT_FOREACH_CHILD_STATUS_OKAY_SEP_VARGS

    • DT_FOREACH_CHILD_STATUS_OKAY_SEP

    • DT_NODE_VENDOR_OR

    • DT_STRING_TOKEN_BY_IDX

    • DT_STRING_UPPER_TOKEN_BY_IDX

    • DT_STRING_UPPER_TOKEN_OR

  • Deprecated macros:

    • DT_LABEL(node_id): use DT_PROP(node_id, label) instead. This is part of the general deprecation of the label property described at the top of this section.

    • DT_INST_LABEL(inst): use DT_INST_PROP(inst, label) instead.

    • DT_BUS_LABEL(node_id): use DT_PROP(DT_BUS(node_id), label)) instead.

    • DT_INST_BUS_LABEL(node_id): use `DT_PROP(DT_INST_BUS(inst), label) instead. Similar advice applies for the rest of the following deprecated macros: if you need to access a devicetree node’s label property, do so explicitly using another property access API macro.

    • DT_GPIO_LABEL_BY_IDX()

    • DT_GPIO_LABEL()

    • DT_INST_GPIO_LABEL_BY_IDX()

    • DT_INST_GPIO_LABEL()

    • DT_SPI_DEV_CS_GPIOS_LABEL()

    • DT_INST_SPI_DEV_CS_GPIOS_LABEL()

    • DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL

• Bindings

  • The bus key in a bindings file can now be a list of strings as well as a string. This allows a single node to declare that it represents hardware which can communicate over multiple bus protocols. The primary use case is simultaneous support for I3C and I2C buses in the same nodes, with the base bus definition provided in dts/bindings/i3c/i3c-controller.yaml.

Libraries / Subsystems

• C Library

  • Added Picolibc as a Zephyr module. Picolibc module is a footprint-optimized full C standard library implementation that is configurable at the build time.

  • C library heap initialization call has been moved from the APPLICATION phase to the POST_KERNEL phase to allow calling the libc dynamic memory management functions (e.g. malloc()) during the application initialization phase.

  • Added strerror() and strerror_r() functions to the minimal libc.

  • Removed architecture-specific off_t type definition in the minimal libc. off_t is now defined as intptr_t regardless of the selected architecture.

• C++ Subsystem

  • Added std::ptrdiff_t, std::size_t, std::max_align_t and std::nullptr_t type definitions to the C++ subsystem cstddef header.

  • Renamed global constructor list symbols to prevent the native POSIX host runtime from executing the constructors before Zephyr loads.

• Cbprintf

  • Updated cbprintf static packaging to interpret unsigned char * as a pointer to a string. See Limitations and recommendations for more details about how to efficienty use strings. Change mainly applies to the logging subsystem since it uses this feature.

• Emul

  • Added EMUL_DT_DEFINE and EMUL_DT_INST_DEFINE to mirror DEVICE_DT_DEFINE and DEVICE_DT_INST_DEFINE respectively.

  • Added EMUL_DT_GET to mirror DEVICE_DT_GET.

  • Removed the need to manually register emulators in their init function (automatically done).

• Filesystem

  • Added cash used to reduce the NVS data lookup time, see CONFIG_NVS_LOOKUP_CACHE option.

  • Changing mkfs options to create FAT32 on larger storage when FAT16 fails.

  • Added CONFIG_FS_FATFS_MIN_SS that allows to set minimal expected sector size to be supported.

• Management

  • MCUMGR race condition when using the task status function whereby if a thread state changed it could give a falsely short process list has been fixed.

  • MCUMGR shell (group 9) CBOR structure has changed, the rc response is now only used for mcumgr errors, shell command execution result codes are instead returned in the ret variable instead, see Shell management for updated information. Legacy bahaviour can be restored by enabling CONFIG_MCUMGR_CMD_SHELL_MGMT_LEGACY_RC_RETURN_CODE.

  • MCUMGR img_mgmt erase command now accepts an optional slot number to select which image will be erased, using the slot input (will default to slot 1 if not provided).

  • MCUMGR CONFIG_OS_MGMT_TASKSTAT_SIGNED_PRIORITY is now enabled by default, this makes thread priorities in the taskstat command signed, which matches the signed priority of tasks in Zephyr, to revert to previous behaviour of using unsigned values, disable this Kconfig.

  • MCUMGR taskstat runtime field support has been added, if CONFIG_OS_MGMT_TASKSTAT is enabled, which will report the number of CPU cycles have been spent executing the thread.

  • MCUMGR transport API drops zst parameter, of zephyr_smp_transport type, from zephyr_smp_transport_out_fn() type callback as it has not been used, and the nb parameter, of net_buf type, can carry additional transport information when needed.

  • A dummy SMP transport has been added which allows for testing MCUMGR functionality and commands/responses.

  • An issue with the UART/shell transports whereby large packets would wrongly be split up with multiple start-of-frame headers instead of only one has been fixed.

  • SMP now runs in its own dedicated work queue which prevents issues running in the system workqueue with some transports, e.g. Bluetooth, which previously caused a deadlock if buffers could not be allocated.

  • Bluetooth transport will now reduce the size of packets that are sent if they are too large for the remote device instead of failing to send them, if the remote device cannot accept a notification of 20 bytes then the attempt is aborted.

  • Unaligned memory access problems for CPUs that do not support it in MCUMGR headers has been fixed.

  • Groups in MCUMGR now use kernel slist entries rather than the custom MCUMGR structs for storage.

  • Levels of function redirection which were previously used to support multiple OS’s have been reduced to simplify code and reduce output size.

  • Bluetooth SMP debug output format specifier has been fixed to avoid a build warning on native_posix platforms.

  • Issue with img_mgmt_dfu_stopped() being wrongly called on success has been fixed.

  • Issue with MCUMGR img_mgmt image erase wrongly returning success during an error condition has been fixed.

  • Unused MCUMGR header files such as mcumgr_util.h have been removed.

  • Verbose error response reporting has been fixed and is now present when enabled.

  • Internal SMP functions have been removed from the public smp.h header file and moved to smp_internal.h

  • Kconfig files have been split up and moved to directories containing the systems they influence.

  • MCUMGR img_mgmt image upload over-riding/hiding of result codes has been fixed.

• Logging

  • Removed legacy (v1) implementation and removed any references to the logging v2.

  • Added LOG_RAW for logging strings without additional formatting. It is similar to LOG_PRINTK but do not append <cr> when new line is found.

  • Improvements in the ADSP backend.

  • File system backend: Only delete old files if necessary.

• IPC

  • Introduced a ‘zephyr,buffer-size’ DT property to set the sizes for TX and RX buffers per created instance.

  • Set WQ priority back to PRIO_PREEMPT to fix an issue that was starving the scheduler.

  • icmsg_buf library was renamed to spsc_pbuf.

  • Added cache handling support to spsc_pbuf.

  • Fixed an issue where the TX virtqueue was misaligned by 2 bytes due to the way the virtqueue start address is calculated

  • Added ipc_service_deregister_endpoint() function to deregister endpoints.

• LoRaWAN

  • Added Class-C support.

  • Upgraded the loramac-node repository to v4.6.0.

  • Moved the REQUIRES_FULL_LIBC library dependency from LoRa to LoRaWAN.

  • Fixed the async reception in SX127x modems.

• Modbus

  • Added user data entry for ADU callback.

• Power management

  • Allow multiple subscribers to latency changes in the policy manager.

  • Added new API to implement suspend-to-RAM (S2RAM). Select CONFIG_PM_S2RAM to enable this feature.

  • Added pm_device_is_powered() to query a device power state.

• POSIX

  • Made tz non-const in gettimeofday() for conformance to spec.

  • Fixed pthread descriptor resource leak. Previously only pthreads with state PTHREAD_TERMINATED could be reused. However, pthread_join() sets the state to PTHREAD_EXITED. Consider both states as candidates in pthread_create().

  • Added perror() implementation.

  • Used consistent timebase in sem_timedwait().

• RTIO

  • Initial version of an asynchronous task and executor API for I/O similar inspired by Linux’s very successful io_uring.

  • Provided a simple linear and limited concurrency executor, simple task queuing, and the ability to poll for task completions.

• SD Subsystem

  • SDMMC STM32: Now compatible with STM32L5 series. Added DMA support for DMA-V1 compatible devices.

  • Added support for handling the DISK_IOCTL_CTRL_SYNC ioctl call. this enables the filesystem api fs_sync().

• Settings

  • Added API function settings_storage_get() which allows to get the storage instance used by the settings backed to store its records.

• Shell

  • Added new API function checking shell readiness: shell_ready().

  • Added option to control formatting of the logging timestamp.

  • Added missing asserts to the shell api functions.

  • MQTT backend: bug fix to handle negative return value of the wait function.

  • A new backends command that lists the name and number of active shell backends.

  • Fixed handling mandatory args with optional raw arg.

• Storage

  • flash_area_open() returns error if area’s flash device is unreachable.

  • flash_area components were reworked so build-time reference to the flash device is used instead of its name with runtime driver buinding.

  • Added FIXED_PARTITION_ macros that move flash_map to use DTS node labels.

• Testsuite

  • Added Kconfig support to unit_testing platform.

  • Migrated tests to use CONFIG_ZTEST_NEW_API.

  • Added ztest options for shuffling tests/suites via:

    • CONFIG_ZTEST_SHUFFLE

    • CONFIG_ZTEST_SHUFFLE_SUITE_REPEAT_COUNT

    • CONFIG_ZTEST_SHUFFLE_TEST_REPEAT_COUNT

  • Added ztest native_posix command line arguments for running specific tests/suites using --test suite_name:* or --test suite_name::test_name command line arguments.

• Storage

  • Flash Map API deprecates usage of FLASH_AREA_ macros and replaces them with FIXED_PARTITION_ macros. This follows removal of label property from DTS nodes.

HALs

• Atmel

  • sam: Fixed incorrect CIDR values for revision b silicon of SAMV71 devices.

• Espressif

  • Updated Espressif HAL with esp-idf 4.4.1 updates.

  • Updated nrfx to version 2.9.0.

• RPi Pico

  • Renamed adc_read to pico_adc_read, to avoid name collision with Zephyr’s API.

• STM32

  • stm32cube: update stm32f7 to cube version V1.17.0.

  • stm32cube: update stm32g0 to cube version V1.6.1.

  • stm32cube: update stm32u5 to cube version V1.1.1.

  • stm32cube: update stm32wb to cube version V1.14.0.

  • pinctrl: some pin definitions did not contain the “_c” suffix, used by pins with analog switch on certain H7 devices.

• TI

  • simplelink: cc13x2_cc26x2: include ADC driverlib sources.

  • simplelink: cc13x2_cc26x2: include flash driverlib sources.

  • cc13x2: kconfig conditions for P variant support & custom RF hwattrs.

  • cc13x2_cc26x2: update to TI SimpleLink SDK 4.40.04.04.

MCUboot

• Removed device_get_binding() usage in favor of DEVICE_DT_GET().

• Added support for generic watchdog0 alias.

• Enabled watchdog feed by default.

• Dropped the CONFIG_BOOT_IMAGE_ACCESS_HOOKS_FILE option. The inclusion of the Hooks implementation file is now up to the project’s customization.

• Switched zephyr port from using FLASH_AREA_ macros to FIXED_PARTITION_ macros.

• Made flash_map_backend.h compatible with a C++ compiler.

• Allowed to get the flash write alignment based on the zephyr,flash DT chosen node property.

• boot_serial:

  • Upgraded from cddl-gen v0.1.0 to zcbor v0.4.0.

  • Refactored and optimized the code, mainly in what affects the progressive erase implementation.

  • Fixed a compilation issue with the echo command code.

• imgtool:

  • Added support for providing a signature through a third party.

Trusted Firmware-M

• Allowed enabling FPU in the application when TF-M is enabled.

• Added option to exclude non-secure TF-M application from build.

• Relocated mergehex.py to scripts/build.

• Added option for custom reset handlers.

Documentation

Tests and Samples

• A large number of tests have been reworked to use the new ztest API, see Test Framework for more details. This should be used for newly introduce tests as well.

• smp_svr Bluetooth overlay (overlay-bt) has been reworked to increase throughput and enable packet reassembly.

• Added test for the new shell API function: shell_ready().
