| |
| * ARM |
| |
| * Architectural support for Arm Cortex-M has been separated from Arm |
| Cortex-A and Cortex-R. This includes separate source modules to handle |
| tasks like IRQ management, exception handling, thread handling and swap. |
| For implementation details see :github:`60031`. |

| |
| * 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. |

| * SPI |
| |

| |
| * 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`. |
| |
| * 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 transport. 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. |
| |
| * 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. |
