STM32F103C8T6 problem debuging in CubeIDE

ONadr.1

Hello,

I bought few Blue pill modules with this MCU. But I have a problem with them in CubeIDE (Eclipse) When I try debuging or write code into MCU, there is an Error (underneath) for all modules with this MCU (STM32F103C8T6, 99lKA 98, MYS 803)

I have the same modules with CPU form different series, and there is no problem here.

A try connect this "bad" modules to CubeProgrammer and there is everything OK. I can clear Flash, write code from file, read OB and so on. I use ST LINK V2 (two pieces, the same behavior)

I try to check where the problem is, but without succes. Perharps, anybody solve this problem and could help me.

Thanks.

Maybe your devices is in stop mode, you need add to script debug stop mode

How can I recognize it? I completely clear FLASH MCU a check every OB working and not working MCU. They were identical.

It's probably a counterfeit chip that ST-Link and/or GDB detected and decided not to communicate with.

It is possible. But I dont understand, why ST Programer works corectly and code is ful functional after programing by ST Programmer. When I check the protocol from ST Programmer, I notice ID

 Device ID : 0x410

and gdb reported

Vendor = 0x3B

but I am not sure, that it is the same meaning.

Erase MCU with Programmer and try start debug with empty MCU

I try, but problem persist. I give it up, Perharps I buy few new MCU and rework them.

Thanks for yours advice.
