| Build system and infrastructure |
| ******************************* |
| |
| * SCA (Static Code Analysis) |
| |
| * Added support for CodeChecker |
| |
| * Twister now supports ``required_snippets`` in testsuite .yml files, this can |
| be used to include a snippet when a test is ran (and exclude any boards from |
| running that the snippet cannot be applied to). |
| |
| * Interrupts |
| |
| * Added support for shared interrupts |
| |
| * Added support for setting MCUboot encryption key in sysbuild which is then |
| propagated to the bootloader and target images to automatically create |
| encrypted updates. |
| |
| * Build time priority checking: enable build time priority checking by default. |
| This fails the build if the initialization sequence in the final ELF file |
| does not match the devicetree hierarchy. It can be turned off by disabling |
| the :kconfig:option:`COFNIG_CHECK_INIT_PRIORITIES` option. |
| |
| * Added a new ``initlevels`` target for printing the final device and |
| :c:macro:`SYS_INIT` initialization sequence from the final ELF file. |
| |
| Drivers and Sensors |
| ******************* |
| |
| * ADC |
| |
| * Battery-backed RAM |
| |
| * CAN |
| |
| * Clock control |
| |
| * Added support for Nuvoton NuMaker M46x |
| |
| * Counter |
| |
| * Crypto |
| |
| * DAC |
| |
| * DFU |
| |
| * Disk |
| |
| * Display |
| |
| * Added support for ST7735S (in ST7735R driver) |
| |
| * DMA |
| |
| * EEPROM |
| |
| * Entropy |
| |
| * ESPI |
| |
| * Ethernet |
| |
| * Added :kconfig:option:`CONFIG_ETH_NATIVE_POSIX_RX_TIMEOUT` to set rx timeout for native posix. |
| |
| * Flash |
| |
| * Introduce npcx flash driver that supports two or more spi nor flashes via a |
| single Flash Interface Unit (FIU) module and Direct Read Access (DRA) mode |
| for better performance. |

| |
| * FPGA |
| |
| * Fuel Gauge |
| |
| * GPIO |

| |
| * hwinfo |
| |
| * I2C |
| |
| * I2S |
| |
| * I3C |
| |
| * IEEE 802.15.4 |
| |
| * A new mandatory method attr_get() was introduced into ieee802154_radio_api. |
| Drivers need to implement at least |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_PAGES and |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_RANGES. |
| * The hardware capabilities IEEE802154_HW_2_4_GHZ and IEEE802154_HW_SUB_GHZ |
| were removed as they were not aligned with the standard and some already |
| existing drivers couldn't properly express their channel page and channel |
| range (notably SUN FSK and HRP UWB drivers). The capabilities were replaced |
| by the standard conforming new driver attribute |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_PAGES that fits all in-tree drivers. |
| * The method get_subg_channel_count() was removed from ieee802154_radio_api. |
| This method could not properly express the channel range of existing drivers |
| (notably SUN FSK drivers that implement channel pages > 0 and may not have |
| zero-based channel ranges or UWB drivers that could not be represented at |
| all). The method was replaced by the new driver attribute |
| IEEE802154_ATTR_PHY_SUPPORTED_CHANNEL_RANGES that fits all in-tree drivers. |
| |
| * Interrupt Controller |
| |
| * GIC: Architecture version selection is now based on the device tree |
| |
| * Input |
| |
| * New drivers: :dtcompatible:`gpio-qdec`, :dtcompatible:`st,stmpe811`. |
| |
| * Drivers converted from Kscan to Input: :dtcompatible:`goodix,gt911` |
| :dtcompatible:`xptek,xpt2046` :dtcompatible:`hynitron,cst816s` |
| :dtcompatible:`microchip,cap1203`. |
| |
| * Added a Kconfig option for dumping all events to the console |
| :kconfig:option:`CONFIG_INPUT_EVENT_DUMP` and new shell commands |
| :kconfig:option:`CONFIG_INPUT_SHELL`. |
| |
| * Merged ``zephyr,gpio-keys`` into :dtcompatible:`gpio-keys` and added |
| ``zephyr,code`` codes to all in-tree board ``gpio-keys`` nodes. |
| |
| * Renamed the callback definition macro from ``INPUT_LISTENER_CB_DEFINE`` to |
| :c:macro:`INPUT_CALLBACK_DEFINE`. |
| |
| * IPM |
| |
| * KSCAN |
| |
| * LED |
| |
| * MBOX |
| |
| * MEMC |
| |
| * PCIE |
| |
| * PECI |
| |
| * Pin control |
| |
| * Added support for Nuvoton NuMaker M46x |
| |
| * PWM |
| |
| * Power domain |
| |
| * Regulators |
| |
| * Reset |
| |
| * Added support for Nuvoton NuMaker M46x |
| |
| * Retained memory |
| |
| * Added support for allowing mutex support to be forcibly disabled with |
| :kconfig:option:`CONFIG_RETAINED_MEM_MUTEX_FORCE_DISABLE`. |
| |
| * Fixed issue with user mode support not working. |
| |
| * SDHC |
| |
| * Sensor |
| |
| * Reworked the :dtcompatible:`ti,bq274xx` to add ``BQ27427`` support, fixed |
| units for capacity and power channels. |
| |
| * Serial |
| |
| * Added support for Nuvoton NuMaker M46x |
| |
| * NS16550: Reworked how device initialization macros. |
| |
| * CONFIG_UART_NS16550_ACCESS_IOPORT and CONFIG_UART_NS16550_SIMULT_ACCESS |
| are removed. For UART using IO port access, add "io-mapped" property to |
| device tree node. |
| |
| * SPI |
| |
| * Remove npcx spi driver implemented by Flash Interface Unit (FIU) module. |
| |
| * Timer |
| |
| * The TI CC13xx/26xx system clock timer compatible was changed from |
| :dtcompatible:`ti,cc13xx-cc26xx-rtc` to :dtcompatible:`ti,cc13xx-cc26xx-rtc-timer` |
| and the corresponding Kconfig option from :kconfig:option:`CC13X2_CC26X2_RTC_TIMER` |
| to :kconfig:option:`CC13XX_CC26XX_RTC_TIMER` for improved consistency and |
| extensibility. No action is required unless the internal timer was modified. |
| |
| * USB |
| |
| * W1 |
| |
| * Watchdog |
| |
| * WiFi |
| |
| Networking |
| ********** |
| |
| * Time and timestamps in the network subsystem, PTP and IEEE 802.15.4 |
| were more precisely specified and all in-tree call sites updated accordingly. |
| Fields for timed TX and TX/RX timestamps have been consolidated. See |
| :c:type:`net_time_t`, :c:struct:`net_ptp_time`, :c:struct:`ieee802154_config`, |
| :c:struct:`ieee802154_radio_api` and :c:struct:`net_pkt` for extensive |
| documentation. As this is largely an internal API, existing applications will |
| most probably continue to work unchanged. |
| |
| * CoAP: |
| |
| * Use 64 bit timer values for calculating transmission timeouts. This fixes potential problems for |
| devices that stay on for more than 49 days when the 32 bit uptime counter might roll over and |
| cause CoAP packets to not timeout at all on this event. |
| |
| * LwM2M: |
| |
| * Added support for tickless mode. This removes the 500 ms timeout from the socket loop |
| so the engine does not constantly wake up the CPU. This can be enabled by |
| :kconfig:option:`CONFIG_LWM2M_TICKLESS`. |
| * Added new :c:macro:`LWM2M_RD_CLIENT_EVENT_DEREGISTER` event. |
| |
| * Wi-Fi |
| * Added Passive scan support. |
| * The Wi-Fi scan API updated with Wi-Fi scan parameter to allow scan mode selection. |
| |
| USB |
| *** |
| |
| * USB device HID |
| * Kconfig option USB_HID_PROTOCOL_CODE, deprecated in v2.6, is finally removed. |

| |
| Libraries / Subsystems |
| ********************** |
| |
| * Management |
| |
| * Introduced MCUmgr client support with handlers for img_mgmt and os_mgmt. |
| |
| * Added response checking to MCUmgr's :c:enumerator:`MGMT_EVT_OP_CMD_RECV` |
| notification callback to allow applications to reject MCUmgr commands. |
| |
| * MCUmgr SMP version 2 error translation (to legacy MCUmgr error code) is now |
| supported in function handlers by setting ``mg_translate_error`` of |
| :c:struct:`mgmt_group` when registering a group. See |
| :c:type:`smp_translate_error_fn` for function details. |
| |
| * Fixed an issue with MCUmgr img_mgmt group whereby the size of the upload in |
| the initial packet was not checked. |
| |
| * Fixed an issue with MCUmgr fs_mgmt group whereby some status codes were not |
| checked properly, this meant that the error returned might not be the |
| correct error, but would only occur in situations where an error was |
| already present. |
| |
| * Fixed an issue whereby the SMP response function did not check to see if |
| the initial zcbor map was created successfully. |
| |
| * Fixes an issue with MCUmgr shell_mgmt group whereby the length of a |
| received command was not properly checked. |
| |
| * Added optional mutex locking support to MCUmgr img_mgmt group, which can |
| be enabled with :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_MUTEX`. |
| |
| * Added MCUmgr settings management group, which allows for manipulation of |
| zephyr settings from a remote device, see :ref:`mcumgr_smp_group_3` for |
| details. |
| |
| * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_SECONDARY` |
| and :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_CONFIRM_NON_ACTIVE_IMAGE_ANY` |
| that allow to control whether MCUmgr client will be allowed to confirm |
| non-active images. |
| |
| * Added :kconfig:option:`CONFIG_MCUMGR_GRP_IMG_ALLOW_ERASE_PENDING` that allows |
| to erase slots pending for next boot, that are not revert slots. |
| |
| * Added ``user_data`` as an optional field to :c:struct:`mgmt_handler` when |
| :kconfig:option:`CONFIG_MCUMGR_MGMT_HANDLER_USER_DATA` is enabled. |
| |
| * Added optional ``force`` parameter to os mgmt reset command, this can be checked in the |
| :c:enum:`MGMT_EVT_OP_OS_MGMT_RESET` notification callback whose data structure is |
| :c:struct:`os_mgmt_reset_data`. |
| |
| * Added configurable number of SMP encoding levels via |
| :kconfig:option:`CONFIG_MCUMGR_SMP_CBOR_MIN_ENCODING_LEVELS`, which automatically increments |
| minimum encoding levels for in-tree groups if :kconfig:option:`CONFIG_ZCBOR_CANONICAL` is |
| enabled. |
| |
| * File systems |
| |
| * Added support for ext2 file system. |
| * Added support of mounting littlefs on the block device from the shell/fs. |
| * Added alignment parameter to FS_LITTLEFS_DECLARE_CUSTOM_CONFIG macro, it can speed up read/write |
| operation for SDMMC devices in case when we align buffers on CONFIG_SDHC_BUFFER_ALIGNMENT, |
| because we can avoid extra copy of data from card bffer to read/prog buffer. |
| |
| * Retention |
| |
| * Added the :ref:`blinfo_api` subsystem. |
| |
| * Added support for allowing mutex support to be forcibly disabled with |
| :kconfig:option:`CONFIG_RETENTION_MUTEX_FORCE_DISABLE`. |
| |
| * Binary descriptors |
| |
| * Added the :ref:`binary_descriptors` (``bindesc``) subsystem. |
| |
| HALs |
| **** |
| |
| * Nuvoton |
| |
| * Added Nuvoton NuMaker M46x |
| |
| MCUboot |
| ******* |
| |
| * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_NO_DOWNGRADE` |
| that allows to inform application that the on-board MCUboot has been configured |
| with downgrade prevention enabled. This option is automatically selected for |
| DirectXIP mode and is available for both swap modes. |
| |
| * Added :kconfig:option:`CONFIG_MCUBOOT_BOOTLOADER_MODE_OVERWRITE_ONLY` |
| that allows to inform application that the on-board MCUboot will overwrite |
| the primary slot with secondary slot contents, without saving the original |
| image in primary slot. |
| |
| * Fixed issue with serial recovery not showing image details for decrypted images. |
| |
| * Fixed issue with serial recovery in single slot mode wrongly iterating over 2 image slots. |
| |
| * Fixed an issue with boot_serial repeats not being processed when output was sent, this would |
| lead to a divergence of commands whereby later commands being sent would have the previous |
| command output sent instead. |
| |
| * Fixed an issue with the boot_serial zcbor setup encoder function wrongly including the buffer |
| address in the size which caused serial recovery to fail on some platforms. |
| |
| * Fixed wrongly building in optimize for debug mode by default, this saves a significant amount |
| of flash space. |
| |
| * Fixed issue with serial recovery use of MBEDTLS having undefined operations which led to usage |
| faults when the secondary slot image was encrypted. |
| |
| * Fixed issue with bootutil asserting on maximum alignment in non-swap modes. |
| |
| * Added error output when flash device fails to open and asserts are disabled, which will now |
| panic the bootloader. |
| |
| * Added currently running slot ID and maximum application size to shared data function |
| definition. |
| |
| * Added P384 and SHA384 support to imgtool. |
| |
| * Added optional serial recovery image state and image set state commands. |
| |
| * Added ``dumpinfo`` command for signed image parsing in imgtool. |
| |
| * Added ``getpubhash`` command to dump the sha256 hash of the public key in imgtool. |
| |
| * Added support for ``getpub`` to print the output to a file in imgtool. |
| |
| * Added support for dumping the raw versions of the public keys in imgtool. |
| |
| * Added support for sharing boot information with application via retention subsystem. |
| |
| * Added support for serial recovery to read and handle encrypted seondary slot partitions. |
| |
| * Removed ECDSA P224 support. |
| |
| * Removed custom image list boot serial extension support. |
| |
| * Reworked boot serial extensions so that they can be used by modules or from user repositories |
| by switching to iterable sections. |
| |
| * Reworked image encryption support for Zephyr, static dummy key files are no longer in the code, |
| a pem file must be supplied to extract the private and public keys. The Kconfig menu has |
| changed to only show a single option for enabling encryption and selecting the key file. |
| |
| * Reworked the ECDSA256 TLV curve agnostic and renamed it to ``ECDSA_SIG``. |
| |
| * CDDL auto-generated function code has been replaced with zcbor function calls, this now allows |
| the parameters to be supplied in any order. |
| |
| * The MCUboot version in this release is version ``2.0.0+0-rc1``. |
