What’s New

• This release updates to the newest code gen tools. See the Validation Information section for details on what versions of each code gen tools was used to test this release.

• The graphics library grlib is now provided in this release. The display example showcases this library’s capabilities.

• The open-source SPIFFS file system is now provided in this release. An example has been provided to showcase this file system’s capabilities. This file system requires a non-volatile storage (NVS) driver (which is not available on CC32xx devices).

• FATFS has been updated to the latest release (v0.13a).

• FreeRTOS has been updated to v10.0.0.

Upgrade and Compatibility Information

This release breaks compatibility with previous releases of the Core SDK in the following ways:

• Due to the GCC compiler update, C files now require -std=c99 to be included on the compile line. GCC C++ files require -std=c++98 to be included on the compile line.

• The board.c file for the MSP432E requires the NDK_NOUSERAPIS symbol to be defined before including the EMACMSP432E.h file. This is required to minimize the scope of the NDK header files.

• The default TI-RTOS kernel configuration project now includes a reference to NDK_hookInit(), which is used to initialize task hooks. This function is provided by the NDK, but applications that do not use the NDK must provide an empty implementation of this function. A weak version of this function is provided in main_tirtos.c. See the product examples for reference.

• The SimpleLink SDK has moved to the R0.13a release of FatFs. Applications using FatFs will need to update code which invokes f_mkfs() as parameters to this function have changed.
  The f_mkfs() function now requires the following to be provided:
  • path - null-terminated string specifying logical driver to be formatted.
  • opt - File system format (FM_FAT, FM_FAT32, FM_EXFAT, FM_ANY).
  • au - cluster allocation unit size in bytes.
  • work - work buffer used during format process.
  • len - size of the work buffer provided.
    
    

• The FatFS component has undergone a name and path change and requires a modification to the fatfs link resource path in your application from previous SDK releases.

Old Values:

<SDK_INSTALL_DIR>/source/third_party/fatfs/lib/fatfs.<LIBRARY_EXTENSION>

New Values:
