What is new

MCUXpresso SDK version 25.03.00-pvw2 is an early adopter release provided as preview for early development.

The following changes have been implemented compared to the previous SDK release version (24.12.00).

  • Bluetooth LE host stack and applications

    Added

    • PAWR support in BLE Shell sample application.

    • PAWR support in adv_ext_peripheral and adv_ext_central sample applications.

    • New sample applications for FRDM-MCXW72.

    • Gap_SetScanningCallback API.

    • Support for handover connection interval update command.

    Changed

    • Updated HID Device for Windows 11 compatibility.

    • Updated CCC demos to Digital Key R4 spec version 1.0.0.

    • Improved RPA resolution at the Host level, now performed synchronously.

    • Enhanced parsing of the CS procedure in Ranging Service.

    Fixed

    • Corrected parsing of the PAST command in FSCI GAP.

    • Fixed scan event reporting in PAST scenario.

    • Added an error case for Gap_SetChannelMap in the generic event handler.

    Details can be found in CHANGELOG.md.

  • Bluetooth LE controller

    • Added initial experimental support for Bluetooth LE Controller feature: Periodic Advertising with Responses (PAwR)\

    • Minor fixes and stability improvements

  • Transceiver drivers (XCVR)

    • Added support for Bluetooth LE Channel Sounding

    • Added API to control PA ramp type and duration.

  • Connectivity framework

    • Minor Changes (no impact on application)

      • General

        • [General] Various MISRA/Coverity fixes in framework: NVM, RNG, LowPower, FunctionLib and platform files

      • Services

        • [SecLib_RNG] AES-CBC evolution:

          • added AES_CBC_Decrypt() API for sw, SSS and mbedtls variants.

          • Made AES-CBC SW implementation reentrant avoiding use of static storage of AES block.

          • fixed SSS version to update Initialization Vector within SecLib, simplifying caller’s implementation.

          • modified AES_128_CBC_Encrypt_And_Pad() so as to avoid the constraint mandating that 16 byte headroom be available at end of input buffer.

        • [SecLib_RNG] RNG modifications:

          • RNG_GetPseudoRandomData() could return 0 in some error cases where caller expected a negative status.

          • Explicited RNG error codes

          • Added argument checks for all APIs and return gRngBadArguments_d (-2) when wrong

          • added checks of RNG initalization and return gRngNotInitialized_d (-3) when not done

          • fixed correcteness of RNG_GetPrngFunc() and RNG_GetPrngContext() relative to API description.

          • Added RNG_DeInit() function mostly for test and coverage purposes.

          • Improved RNG description in README.md

          • Unified the APIs behaviour between mbedtls and non mbedtls variants.

          • RNG/mbedtls : Prevent RNG_Init() from corrupting RNG entropy context if called more than once.

          • RNG/mbedtls: fixed RNG_GetTrueRandomNumber() to return a proper mbedtls_entropy_func() result.

        • [SecLib_RNG] Use defragmetation option when freeing key object in SecLib_sss to avoid leak in S200 memory

        • [SecLib_RNG] Add new API ECP256_IsKeyValid() to check whether a public key is valid

        • [OtaSupport] Update return status to OTA_Flash_Success when success at the end of InternalFlash_WriteData() and InternalFlash_FlushWriteBuffer() APIs

        • [WorQ] Implementing a simple workqueue service to the framework

        • [SFC] Keep using immediate measurement for some measurement before switching to configuration trig to confirm the calibration made

        • [DBG] Adding modules to framework DBG :

          • sbtsnoop

          • SWO

        • [Common] Fix HAL_CTZ and HAL_RBIT IAR versions

        • [LowPower] Fix wrong tick error calculation in case of infinite timeout

        • [Settings] Add new macro gSettingsRedefineApiName_c to avoid multiple definition of settings API when using connectivity framework repo

      • Platform specific

        • [KW47/MCXW72] Change xtal cload default value from 4 to 8 in order to increase the precision of the link layer timebase in NBU

        • [wireless_mcu] [wireless_nbu] Use new WorkQ service to process framework intercore messages

    Details can be found in CHANGELOG.md

  • IEEE 802.15.4

    • API cleanup: remove unmaintained slotted support

    • support for MAC split architecture

      • fix condition to enter low power

    • minor fixes and stability improvements for connectivity_test example application

    • experimental support for mcxw72 NBU core

  • Zigbee

    • NCP Host Updates and fixes

    • R23 fixes

      • Device can’t establish a new TCLK through ZDO Start Key Update procedure

      • Security Start Key Update Request is not relayed to joining ZED in multi hop key negotiation

    • propagate APS ACK to end-user application

    • documentation updates
