Supported Software and Tools

This version of the CLib FreeRTOS Support Library was validated for compatibility with the following Software and Tools:

Software and Tools Version
ModusToolbox™ Software Environment 3.0.0
GCC Compiler 10.3.1
IAR Compiler 9.40.2
ARM Compiler 6.16
LLVM ARM Compiler 18.1.3

Minimum required ModusToolbox™ Software Environment: v2.0

LLVM ARM Compiler and printf

The LLVM ARM toolchain utilizes the picolibc library.

Because of the implementation in which picolibc handles printf calls, in the context of RTOS applications, it is up to the application to provide thread safety for printf statements when multiple threads share the same stream.
