“ST-Link Debugging Issue: Launch Debugging Failed on STM32 Blue Pill”

[srinathr]

Hello Everyone,
I am attempting to debug code on the STM32 Blue Pill board. The project compiles successfully, but when I start a debug session, it fails with the message “Launch debugging failed,” along with additional error details shown below. I would appreciate any guidance on resolving this issue.
Note: I am using an ST-Link V2 programmer (A2020 version).
Wiring is done correctly checked multiple time.
I had doubts about the Debugger configurations. Are there any other settings must be modifiable, or any other ways are

there?

" Error in final launch sequence:

Failed to start GDB server

Failed to start GDB server

Error in initializing ST-LINK device.

Reason: (18) Could not verify ST device! Abort connection."

Hello @srinathr and welcome to the ST community,

Unfortunately, BluePill boards most probably contain a conterfeit STM32 product.

You may also using a cloned STLINK..

I suggest you to use a ST board with a genuine STM32 chip on it. 

Example: NUCLEO-F103RB

And we will happy to help you.

Review the many threads here on Blue (and other coloured) Pills.

As @mƎALLEm said, they most likely contain a fake STM32 and, therefore, are not guaranteed to work with genuine ST tools.

Using a fake or clone ST-Link only compounds the issue.

More than likely the ST-LinkV2 can't detect voltage from the Bluepill.  Does the Bluepill LED turn on when you plug in the USB cable?
