What’s New

• The Core SDK is a refactored and restructured software distribution based on TI-RTOS 2.x. The directory structure of the product has changed dramatically to make things easier to find and use. The Core SDK is included in SimpleLink MCU SDKs and provides a common set of base software that each of these parent SDKs build upon. The SimpleLink MCU SDKs replace the TI-RTOS product. See the new User’s Guide for more.
• Display module. The examples now use the Display module and UART for output. Examples were previously using the SYS/BIOS System_printf() module to output to the debugger console. The Display module provides a portable output API for use with FreeRTOS, TI-RTOS or another RTOS. Using the UART allows the examples to run from FLASH without a emulator/IDE connection.
• FreeRTOS support including a POSIX pthread, semaphore, etc. library is included.
• Most of the examples have been updated to use a common/shared OS library/configuration.
• Most of the examples have been updated to use POSIX pthread APIs. This enables the same example .c files to be used with either TI-RTOS Kernel of FreeRTOS kernel.

3.01.01.19 introduces new features:

3.01.01.19 resolves the following bugs:

Upgrade and Compatibility Information

• All source code must be recompiled against the updated .h files in this release.
• The top-level ‘os’ directory has been renamed to ‘kernel’. The ‘examples/os’ directory has been renamed to ‘examples/rtos’.
• FatFs. The FatFs software has been moved from ti/mw/fatfs to source/third_party/fatfs directory. Support for the configuration FatFS using the TI-RTOS confg tool has been removed. The FatFS library must now be added to the link line of your application build. Some of this setup was handled behind the scenes in TI-RTOS. Use the fatfs examples in the product as a guideline.
• MISRA updates. All source files and .h files in the root ti/drivers directory (e.g., ti/drivers/UART.h, ti/drivers/UART.c) have been updated to use be MISRA compliant. The primary change is the use C99 ‘sized’ types instead of traditional ‘int’ and ‘unsigned int’ types.
• Major “board file” changes. HwAttrs structures have been extended and updated for most of the drivers. HwAttrs changes come together with a typedef name change (e.g., UARTMSP432_HwAttrs changed to UARTMSP43_HwAttrsV1) to force users with old code to review their HwAttrs structures and update accordingly.
  • count variables - drivers with multiple instances now have a count field instead of the prior NULL-terminated array mechanism.
  • Board_GPIO_LEDX, Board_GPIO_ButtonY. Names of some of these constants have been changed to be more intuitive. The old names are provided for compatibility.
  • Pin ids are now in HwAttrs. The board files have been simplified to now have mainly just data structures. All pin management code has been moved to the drivers. This required the HwAttrs for most drivers to change to include pin ids.
  • Board_initDriver (e.g., Board_initUART()) functions have been removed (macros are provide for compatibility).
  • Significant review and some porting will be required if you want to use a board file from TI-RTOS 2.x with this release.
• Include paths. Some components have moved. These moves will require some changes to the include paths and library paths for existing code.
  • The ti/mw/fatfs directory was moved to third_party/fatfs.
  • driverlib and inc files have moved to ti/devices/devicefamily
• CC3200 support was removed. This release supports the CC3220.
• DPL (driver porting layer) changes. The driver porting APIs has been moved from ti/drivers/ports to ti/drivers/dpl. This is mostly and internal detail, as the DPL APIs are intended for use by drivers and not application software.
• Application stack sizes and heap sizes are specfied in the linker .cmd file instead of the .cfg file.
• The UARTMon module has been removed.
