Stm32CubeIDE 2.0.0 to 2.1.0 update breaks FreeRTOS kernel aware debugging

[DreamOnDirac]

Hi

While running stm32CubeIDE 2.0.0 (and older versions), the the RTOS kernel aware debugging worked as expected (described here for thoose who dont use it):  

https://community.st.com/t5/stm32-mcus/how-to-enable-freertos-run-time-and-stack-usage-view/ta-p/627524

However, since updating to 2.1.0 this seems to have stopped working.

I have tried the #define configTASK_RETURN_ADDRESS NULL as suggested here

https://community.st.com/t5/stm32cubeide-mcus/freertos-backtrace-problem/td-p/858548

But without any change. I have tested GCC 12.3, 13.3 and 14.3 with no change

The "FreeRTOS Queues", "FreeRTOS Task list" and "FreeRTOS Semaphores" views still works as expected.

What can I do to remedy this?

 

Best regards

Martin

What, exactly, are the symptoms of "not working" ?

Have you seen: Issues Debugging FreeRTOS with J-Link.

Hi

The symptoms were that the tasks were listed so that the call stack could be investigated

This is what i expect

This is what i got

Hi @DreamOnDirac,

 

I heard rumor that the version of the RTOS proxy which is integrated into 2.10 has a regression bug compared to 2.0.0. I imagine that one solution would be to replace the RTOS proxy tool from 2.1.0 with the one from 2.0.0...

You find them "roughly" ("roughy" since I am on Mac, you are probably on Windows) here:

STM32CubeIDE 2.1.0/plugins/com.st.stm32cube.ide.mcu.externaltools.rtosproxy.macosaarch64_1.0.0.202601281726/tools

Make a back-up of the tools folder and then replace it with the one from 2.0.0....

Appologies for the inconvenience!

 

Kind regards, Mattias

I had the same problem on linux after upgrading.
After executing the following command in the plugins folder, the task list is visible again.
cp -r com.st.stm32cube.ide.mcu.externaltools.rtosproxy.linux64_1.2.100.202412131345 com.st.stm32cube.ide.mcu.externaltools.rtosproxy.linux64_1.2.200.202601091506
