Debugging STM32 clone

[Johanan]

Due to chips shortage we are trying to test Chinese STM32 clone CH32F103C8T6.

It looks like it has been solved with platformIO:

Debugging of STM32F103 clone “BluePill” board, wrong idcode – Professional Solutions / Debugging – PlatformIO Community

and I tried changing startup GDB commands in Debug settings-> advanced , but no joy.

Can you help?

Thanks.

You must edit the stm32f1x.cfg file to add the line

set CPUTAPID 0

before the first if.

Look for the file in the Debug settings, Debugged device ….

Tried it but it makes no difference, still same error.

Any other ideas?

Thanks

For me, that solved the ID-problem with cloned Blue Pills labelled as stm32f103CBT6.

You might need administrative permission to replace that file.

Furthermore, after an update of openOCD the changed file will be replaced.

Therefore, I keep the changed cfg file in a different folder.
