Hi everyone,
I am experiencing issues with Task Aware Debugging (FreeRTOS Task List) in the latest version of STM32CubeIDE. The "FreeRTOS Task List" view is either empty or not populating correctly, despite the scheduler running and tasks executing effectively on the hardware.
Environment:
IDE: STM32CubeIDE (Latest Version)
MCU: STM32H7S3L8H6x
FreeRTOS Version: V10.6.2 (CMSIS-RTOS V2 wrapper)
STM32Cube 2.0.0
Interestingly enough, the runtimestats itsef are working.
Does anyone have similar issues?

<p>
Task Aware Debugging in STM32CubeIDE usually depends on specific FreeRTOS symbols being visible to the debugger.
When CMSIS-RTOS V2 is enabled, the abstraction layer can sometimes interfere with task enumeration,
especially if the IDE does not fully support the wrapper version being used.
This can result in an empty or partially populated FreeRTOS Task List view even though tasks are running correctly.
