| Zephyr 3.7.0 (Working Draft) |
| ############################ |
| |
| We are pleased to announce the release of Zephyr version 3.7.0. |
| |
| Major enhancements with this release include: |
| |
| * A new, completely overhauled hardware model has been introduced. This changes |
| the way both SoCs and boards are named, defined and constructed in Zephyr. |
| Additional information can be found in the :ref:`board_porting_guide`. |
| * Zephyr now requires Python 3.10 or higher |
| * Trusted Firmware-M (TF-M) 2.1.0 and Mbed TLS 3.6.0 have been integrated into Zephyr. |
| Both of these versions are LTS releases. |
| |
| An overview of the changes required or recommended when migrating your application from Zephyr |
| v3.6.0 to Zephyr v3.7.0 can be found in the separate :ref:`migration guide<migration_3.7>`. |

| |
| Architectures |
| ************* |
| |
| * ARC |
| |
| * ARM |
| |
| * ARM64 |
| |
| * Implemented symbol names in the backtraces, enable by selecting :kconfig:option:`CONFIG_SYMTAB` |
| |
| * RISC-V |
| |
| * The fatal error message triggered from a fault now contains the callee-saved-registers states. |
| |
| * Implemented stack unwinding |
| |
| * Frame-pointer can be selected to enable precise stack traces at the expense of slightly |
| increased size and decreased speed. |
| |
| * Symbol names can be enabled by selecting :kconfig:option:`CONFIG_EXCEPTION_STACK_TRACE_SYMTAB` |
| |
| * Xtensa |
| |
| Kernel |
| ****** |
| |
| * Added :c:func:`k_uptime_seconds` function to simplify `k_uptime_get() / 1000` usage. |
| |
| * Added :c:func:`k_realloc`, that uses kernel heap to implement traditional :c:func:`realloc` |
| semantics. |
| |
| Bluetooth |
| ********* |
| * Audio |
| |
| * Removed ``err`` from :c:struct:`bt_bap_broadcast_assistant_cb.recv_state_removed` as it was |
| redundant. |
| |
| * The broadcast_audio_assistant sample has been renamed to bap_broadcast_assistant. |
| The broadcast_audio_sink sample has been renamed to bap_broadcast_sink. |
| The broadcast_audio_source sample has been renamed to bap_broadcast_source. |
| The unicast_audio_client sample has been renamed to bap_unicast_client. |
| The unicast_audio_server sample has been renamed to bap_unicast_server. |
| The public_broadcast_sink sample has been renamed to pbp_public_broadcast_sink. |
| The public_broadcast_source sample has been renamed to pbp_public_broadcast_source. |
| |
| * The CAP Commander and CAP Initiator now no longer require CAS to be discovered for |
| :code:`BT_CAP_SET_TYPE_AD_HOC` sets. This allows applications to use these APIs on e.g. |
| BAP Unicast Servers that do not implement the CAP Acceptor role. |
| |
| * Host |
| |
| * Added Nordic UART Service (NUS), enabled by the :kconfig:option:`CONFIG_BT_ZEPHYR_NUS`. |
| This Service exposes the ability to declare multiple instances of the GATT service, |
| allowing multiple serial endpoints to be used for different purposes. |
| |
| * Implemented Hands-free Audio Gateway (AG), enabled by the :kconfig:option:`CONFIG_BT_HFP_AG`. |
| It works as a device that is the gateway of the audio. Typical device acting as Audio |
| Gateway is cellular phone. It controls the device (Hands-free Unit), that is the remote |
| audio input and output mechanism. |
| |
| * Implemented Advanced Audio Distribution Profile (A2DP) and Audio/Video Distribution Transport |
| Protocol (AVDTP), A2DP is enabled by :kconfig:option:`CONFIG_BT_A2DP`, AVDTP is enabled |
| by :kconfig:option:`CONFIG_BT_AVDTP`. They implement the protocols and procedures that |
| realize distribution of audio content of high quality in mono, stereo, or multi-channel modes. |
| A typical use case is the streaming of music content from a stereo music player to headphones |
| or speakers. The audio data is compressed in a proper format for efficient use of the limited |
| bandwidth. |
| |
| * Reworked the transmission path for data and commands. The "BT TX" thread has been removed, along |
| with the buffer pools for HCI fragments and L2CAP segments. All communication with the |
| Controller is now exclusively done in the system workqueue context. |
| |
| * HCI Driver |
| |
| * Added support for Ambiq Apollo3 Blue series. |
| |

| Build system and Infrastructure |
| ******************************* |
| |
| * CI-enabled blackbox tests were added in order to verify correctness of the vast majority of Twister flags. |
| |
| * A ``socs`` folder for applications has been introduced that allows for Kconfig fragments and |
| devicetree overlays that should apply to any board target using a particular SoC and board |
| qualifier. |
| |
| * :ref:`Board/SoC flashing configuration<flashing-soc-board-config>` settings have been added. |
| |
| * Deprecated the global CSTD cmake property in favor of the :kconfig:option:`CONFIG_STD_C` |
| choice to select the C Standard version. Additionally subsystems can select a minimum |
| required C Standard version, with for example :kconfig:option:`CONFIG_REQUIRES_STD_C11`. |
| |
| * Fixed issue with passing UTF-8 configs to applications using sysbuild. |
| |
| * Fixed issue whereby domain file in sysbuild projects would be loaded and used with outdated |
| information if sysbuild configuration was changed, and ``west flash`` was ran directly after. |
| |
| * Fixed issue with Zephyr modules not being listed in sysbuild if they did not have a Kconfig |
| file set. |
| |
| * Add sysbuild ``SB_CONFIG_COMPILER_WARNINGS_AS_ERRORS`` Kconfig option to turn on |
| "warning as error" toolchain flags for all images, if set. |
| |
| Drivers and Sensors |
| ******************* |
| |
| * ADC |
| |
| * Auxiliary Display |
| |

| limit to automatically start charging again. |
| |
| * Battery backed up RAM |
| |
| * CAN |
| |
| * Deprecated the :c:func:`can_calc_prescaler` API function, as it allows for bitrate |
| errors. Bitrate errors between nodes on the same network leads to them drifting apart after the |
| start-of-frame (SOF) synchronization has taken place, leading to bus errors. |
| * Added :c:func:`can_get_bitrate_min` and :c:func:`can_get_bitrate_max` for retrieving the minimum |
| and maximum supported bitrate for a given CAN controller/CAN transceiver combination, reflecting |
| that retrieving the bitrate limits can no longer fail. Deprecated the existing |
| :c:func:`can_get_min_bitrate` and :c:func:`can_get_max_bitrate` API functions. |
| * Extended support for automatic sample point location to also cover :c:func:`can_calc_timing` and |
| :c:func:`can_calc_timing_data`. |

| transceiver. |
| * Added support for specifying the minimum bitrate supported by a CAN controller in the internal |
| ``CAN_DT_DRIVER_CONFIG_GET`` and ``CAN_DT_DRIVER_CONFIG_INST_GET`` macros. |
| * Added a new CAN controller API function :c:func:`can_get_min_bitrate` for getting the minimum |
| supported bitrate of a CAN controller/transceiver combination. |
| * Updated the CAN timing functions to take the minimum supported bitrate into consideration when |
| validating the bitrate. |
| * Made the ``sample-point`` and ``sample-point-data`` devicetree properties optional. |

| * Added a loopback disk driver, to expose a disk device backed by a file. |
| A file can be registered with the loopback disk driver using |
| :c:func:`loopback_disk_access_register` |
| * Added support for :c:macro:`DISK_IOCTL_CTRL_INIT` and |
| :c:macro:`DISK_IOCTL_CTRL_DEINIT` macros, which allow for initializing |
| and de-initializing a disk at runtime. This allows hotpluggable |
| disk devices (like SD cards) to be removed and reinserted at runtime. |
| |
| * Display |
| |
| * All in tree displays capable of supporting the :ref:`mipi_dbi_api` have |
| been converted to use it. GC9X01X, UC81XX, SSD16XX, ST7789V, ST7735R based |
| displays have been converted to this API. Boards using these displays will |
| need their devicetree updated, see the display section of |
| :ref:`migration_3.7` for examples of this process. |
| * Added driver for ST7796S display controller (:dtcompatible:`sitronix,st7796s`) |

| * The hawkBit subsystem has been reworked to use the settings subsystem to store the hawkBit |
| configuration. |
| |
| * By enabling :kconfig:option:`CONFIG_HAWKBIT_SET_SETTINGS_RUNTIME`, the hawkBit settings can |
| be configured at runtime. Use the :c:func:`hawkbit_set_config` function to set the hawkBit |
| configuration. It can also be set via the hawkBit shell, by using the ``hawkbit set`` |
| command. |
| |
| * When using the hawkBit autohandler and an update is installed, the device will now |
| automatically reboot after the installation is complete. |
| |
| * By enabling :kconfig:option:`CONFIG_HAWKBIT_CUSTOM_DEVICE_ID`, a callback function can be |
| registered to set the device ID. Use the :c:func:`hawkbit_set_device_identity_cb` function to |
| register the callback. |
| |
| * By enabling :kconfig:option:`CONFIG_HAWKBIT_CUSTOM_ATTRIBUTES`, a callback function can be |
| registered to set the device attributes that are sent to the hawkBit server. Use the |
| :c:func:`hawkbit_set_custom_data_cb` function to register the callback. |
| |
| * MCUmgr |
| |
| * Instructions for the deprecated mcumgr go tool have been removed, a list of alternative, |
| supported clients can be found on :ref:`mcumgr_tools_libraries`. |
| |
| * Logging |
| |
| * By enabling :kconfig:option:`CONFIG_LOG_BACKEND_NET_USE_DHCPV4_OPTION`, the IP address of the |
| syslog server for the networking backend is set by the DHCPv4 Log Server Option (7). |
| |
| * Modem modules |
| |
| * Added modem pipelink module which shares modem pipes globally, allowing device drivers to |
| create and set up pipes for the application to use. |
| |
| * Simplified the modem pipe module's synchronization mechanism to only protect the callback |
| and user data. This matches the actual in-tree usage of the modem pipes. |
| |
| * Added ``modem_stats`` module which tracks the usage of buffers throughout the modem |
| subsystem. |
| |
| * Picolibc |
| |
| * Power management |
| |
| * Crypto |
| |
| * Mbed TLS was updated to 3.6.0. Release notes can be found at: |
| https://github.com/Mbed-TLS/mbedtls/releases/tag/v3.6.0 |
| * When any PSA crypto provider is available in the system |
| (:kconfig:option:`CONFIG_MBEDTLS_PSA_CRYPTO_CLIENT` is enabled), desired PSA features |
| must now be explicitly selected through ``CONFIG_PSA_WANT_xxx`` symbols. |
| * Choice symbols :kconfig:option:`CONFIG_MBEDTLS_PSA_CRYPTO_LEGACY_RNG` and |
| :kconfig:option:`CONFIG_MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG` were added in order |
| to allow the user to specify how Mbed TLS PSA crypto core should generate random numbers. |
| The former option, which is the default, relies on legacy entropy and CTR_DRBG/HMAC_DRBG |
| modules, while the latter relies on CSPRNG drivers. |
| * :kconfig:option:`CONFIG_MBEDTLS_PSA_P256M_DRIVER_ENABLED` enables support |
| for the Mbed TLS's p256-m driver PSA crypto library. This is a Cortex-M SW |
| optimized implementation of secp256r1 curve. |
| |
| * Random |
| |
| * Besides the existing :c:func:`sys_rand32_get` function, :c:func:`sys_rand8_get`, |
| :c:func:`sys_rand16_get` and :c:func:`sys_rand64_get` are now also available. |
| These functions are all implemented on top of :c:func:`sys_rand_get`. |
| |
| * Retention |
| |
| * SD |
| |
| * SDMMC and SDIO frequency and timing selection logic have been reworked, |
| to resolve an issue where a timing mode would not be selected if the |
| SDHC device in use did not report support for the maximum frequency |
| possible in that mode. Now, if the host controller and card both report |
| support for a given timing mode but not the highest frequency that |
| mode supports, the timing mode will be selected and configured at |
| the reduced frequency (:github:`72705`). |
| |
| * State Machine Framework |
| |
| * The :c:macro:`SMF_CREATE_STATE` macro now always takes 5 arguments. |
| * Transition sources that are parents of the state that was run now choose the correct Least |
| Common Ancestor for executing Exit and Entry Actions. |
| * Passing ``NULL`` to :c:func:`smf_set_state` is now not allowed. |
| |
| * Storage |
| |
| * FAT FS: It is now possible to expose file system formatting functionality for FAT without also |
| enabling automatic formatting on mount failure by setting the |
| :kconfig:option:`CONFIG_FS_FATFS_MKFS` Kconfig option. This option is enabled by default if |
| :kconfig:option:`CONFIG_FILE_SYSTEM_MKFS` is set. |
| |
| * FS: It is now possible to truncate a file while opening using :c:func:`fs_open` |
| and by passing ``FS_O_TRUNC`` flag. |
| |
| * POSIX API |
| |
| * LoRa/LoRaWAN |
| |
| * Added the Fragmented Data Block Transport service, which can be enabled via |
| :kconfig:option:`CONFIG_LORAWAN_FRAG_TRANSPORT`. In addition to the default fragment decoder |
| implementation from Semtech, an in-tree implementation with reduced memory footprint is |
| available. |
| |
| * Added a sample to demonstrate LoRaWAN firmware-upgrade over the air (FUOTA). |

| LVGL |
| **** |
| |
| LVGL was updated to 8.4.0. Release notes can be found at: |
| https://docs.lvgl.io/8.4/CHANGELOG.html#v8-4-0-19-march-2024 |
| |
| Additionally, the following changes in Zephyr were done: |
| |
| * Added support to place memory pool buffers in ``.lvgl_heap`` section by enabling |
| :kconfig:option:`CONFIG_LV_Z_MEMORY_POOL_CUSTOM_SECTION` |
| |
| * Removed kscan-based pointer input wrapper code. |
| |
| * Corrected encoder button behavior to emit ``LV_KEY_ENTER`` events correctly. |
| |
| * Improved handling for :samp:`invert-{x,y}` and ``swap-xy`` configurations. |
| |
| * Added ``LV_MEM_CUSTOM_FREE`` call on file closure. |
| |
| * Added missing Kconfig stubs for DMA2D symbols. |
| |
| * Integrated support for LVGL rounder callback function. |
| |
| Tests and Samples |
| ***************** |
| |
| * Added snippet for easily enabling UART over Bluetooth LE by passing ``-S nus-console`` during |
| ``west build``. This snippet sets the :kconfig:option:`CONFIG_BT_ZEPHYR_NUS_AUTO_START_BLUETOOTH` |
| which allows non-Bluetooth samples that use the UART APIs to run without modifications |
| (e.g: Console and Logging examples). |
| |
| * Removed ``GSM_PPP`` specific configuration overlays from samples ``net/cloud/tagoio`` and |
| ``net/mgmt/updatehub``. The ``GSM_PPP`` device driver has been deprecated and removed. The new |
| ``MODEM_CELLULAR`` device driver which replaces it uses the native networking stack and ``PM`` |
| subsystem, which like ethernet, requires no application specific actions to set up networking. |
| |
| * Removed ``net/gsm_modem`` sample as the ``GSM_PPP`` device driver it depended on has been |
| deprecated and removed. The sample has been replaced by the sample ``net/cellular_modem`` |
| based on the ``MODEM_CELLULAR`` device driver. |
