Unable to debug from STM32CubeIDE

[TomC1]

Hi,

I am having a problem where I am unable to run my code in debug mode from within STM32CubeIDE v1.15.

I can program the device fine with STM32CubeProgrammer, but when I try to debug I get this output:

log output file: C:\Users\[me]\AppData\Local\Temp\STM32CubeProgrammer_a23280.log

ST-LINK SN : 004C002F3532510F31333430

Error in STM32CubeProgrammer

Shutting down...

For comparison, when I connect to the MCU through the Cube Programmer, I get this output:

Could anyone help shed some light on why I am unable to debug?

For reference, I am using the most recent version of all tools, and I have tried several of our units, several different STLinks (v2 and v3) and even multiple laptops, all with the same outcome.

Further info, I also get this dialog when the debug fails:

What microcontroller, and on what board?

Are you using 'Connect Under Reset' ?

The "ST-LINK error (DEV_UNKNOWN_MCU_TARGET)" would seem to be key:

Hello,

It's a known issue with STM32CubeIDE v1.15. Already escalated internally to be fixed asap.

See these threads.

STMCubeIDE seems to give endless problems. Since the MX can generate c++ code what is the possibility of using all the generated files in C++ Builder? If This is possible, which files should I look for? Has anyone tried this before or will we just have to be stuck with STMCubeIDE. 
I do note that many tutorials using  STMCubeMX susally have their code generated using other toolchains and not the STMCubeIDE.
Could someone shed some light on this matter?

Hello,

This is another subject. Please open a new thread for this. Another ST team can help you.

Thank you for your understanding.

It's here: https://community.st.com/t5/feedback-forum/using-c-builder/td-p/660342

Dunno why it's under 'Forum Feedback', though?

Surely, 'Other Tools (MCUs)' would make more sense?

I don't understand why this is showing as an accepted solution to my thread.  I certainly did not accept it, because it did not in any way solve my problem.

The only solution I have found was to migrate my project to Visual Studio with VisualGDB.
