Upgrade and Compatibility Information

• The VCE (Vector Computation Engine) peripheral has been renamed to APU (Algorithm Processing Unit) and all existing VCELPF3 APIs have been renamed to APULPF3. Any application that references this API must take care to migrate accordingly. For example, VCELPF3_init() must be renamed to APULPF3_init(). Additionally, some function signatures have changed (APULPF3_vectorSum and APULPF3_jacobiEVD), and some new APIs have been added that are now available. See also the release notes for relevant bug-fixes for the APU driver. For a complete list of APIs, see APULPF3.h.
• The mechanism to route events internally has changed for several drivers, and corresponding hardware attribute structures have changed. Any applications that utilize hardcoded driver configurations, rather than dynamically generating these with SysConfig, will need to update to be compatible with the driver implementation. The following drivers are affected:
  • SPI

    • hwAttrs struct updated with 2 new fields:

      uint32_t rxChannelSubscriberId
      uint32_t txChannelSubscriberId

  • ADCBuf

    • hwAttrs struct members renamed:

      .dataDmaEvtReg -> .dataDmaSubscriberId
      .auxDmaEvtReg -> .auxDmaSubscriberId

    • hwAttrs struct members removed:

      uint8_t dataDmaEvtMux
      uint8_t auxDmaEvtMux

  • BatteryMonitor

    • BatMonSupportLPF3_Config struct members removed:

      uint32_t: intMux

    • BatMonSupportLPF3_Config struct members added:

      uint32_t intSubscriberId

  • UART2

    • hwAttrs struct members added:

      uint32_t rxChannelSubscriberId
      uint32_t txChannelSubscriberId

  • Comparator

    • hwAttrs struct members removed:

      uint32_t: intMux

    • hwAttrs struct members added:

      uint32_t intSubscriberId

• Note that the python version required for some of the tools distributed in the CoreSDK has been updated from version 3.8 to 3.10.

Core SDK 7.40.02 (Dec, 2023)

• This version of the SDK contains the FreeRTOS kernel source files used by the SDK. Prior versions of the SDK required that the user download FreeRTOS separately and specify the path to the FreeRTOS kernel source files by defining FREERTOS_INSTALL_DIR in their project or their IDE. This is no longer necessary.

  • SDK examples used to add include paths relative to FREERTOS_INSTALL_DIR to all FreeRTOS examples. Users importing an example from this SDK and then using that as baseline for their application do not need to worry about include paths. Users switching SDKs while keeping an existing project should update their include paths as below. Note that the variables and paths below are examples, and may vary depending on your IDE/environment and device.

    // Before
    "-I$(FREERTOS_INSTALL_DIR)/FreeRTOS/Source/include"
    "-I$(FREERTOS_INSTALL_DIR)/FreeRTOS/Source/portable/GCC/ARM_CM0"
    
    // After
    "-I$(SIMPLELINK_LOWPOWER_F3_SDK_INSTALL_DIR)/source/third_party/freertos/include"
    "-I$(SIMPLELINK_LOWPOWER_F3_SDK_INSTALL_DIR)/source/third_party/freertos/portable/GCC/ARM_CM0"

  • Using a different version of FreeRTOS is now only possibly by changing the Add FreeRTOS Source Path Prefix setting in SysConfig that allows for modifying the relative path to the FreeRTOS source code.
• Logging has received several quality of life updates.
  • Preprocessor guards are now evaluated on a per-module basis. That means that emitting Log statements is now more granular for compilation units compiled within a project. See TIUTILS-105 for more details.
  • Global Log levels in SysConfig are enabled by default but can still be disabled after the fact. Users no longer need to go enable all the global Log levels after adding a Log module in SysConfig.
  • A new Log sink based on UART is now available, LogSinkUart. This sink fills an internal buffer and then asynchronously sends the Log records out over UART while the CPU is idle. It is specifically meant to support devices that do not have support for dedicated instrumentation hardware such as ITM.
