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

    • 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
