What’s New
- 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_DIRin their project or their IDE. This is no longer necessary.SDK examples used to add include paths relative to
FREERTOS_INSTALL_DIRto 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 Prefixsetting 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.
