Bluepill -- STlink V2 -- GDB server -- All Troubleshooting steps taken -- Problem Persists

[learner]

Background:
I recently bought a STM32 blue pill and STLink V2 online. This is my first time using a STM board, I am quite familiar with arduino, esp and 8051(Proteus simulation).

Problem:
I have attached the 'error.png' file below it is a 'failed to start GDB server error' (for people who cannot for some reason see the file). I have done the following troubleshooting steps, which I found on chatgpt, youtube and this community:
1) Check debugger configuration settings. (attached screenshots)
2) Tried lowering the debug frequency from 'Auto'.
3) Tried all reset behaviors: 'Connect under reset', 'Software reset' etc...
4) Upgraded the stlink firmware
5) Checked and found 'STM32 STlink' is showing up in the device manager
6) Only have windows defender on my laptop, still I excluded entire 'STM32CubeIDE_1.19.0' folder.
7) Re-did the wiring and everything seems correct.
8) Rebooted everything twice and didn't work
9) Tried clean the project, delete and remake the debug configuration file and complete build a new project and nothing worked.
10) Tried my friend's laptop and a different blue pill and STLink V1, didn't work
11) Tried reinstalling stlink GDB server from https://www.st.com/en/development-tools/st-link-server.html and didn't work

At this point I think I tried everything I could find online, I really hope someone from this community helps me find where I went wrong, or if I am making some silly mistake. Also, I tried using the STM32CubeProgrammer and the code flashes just fine (I still want to try the debugger). 

Regards and Thank you for reading this long query!

Knock-off programmers don't work well with STM32CubeIDE. Consider getting a genuine board.

Hello @learner and welcome to the ST-Community,

First, this is not an STM board. It's manufactured by Chinese and we don't recommend its usage due to the fake chips soldered on it that can induces to some usage issues.

Second, use one of the STM genuine board like NUCLEO-F103RB.

So with CubeProgrammer it connects and is like expected ?

In IDE you could try using other debug -> openOCD

And set : software reset (hardware reset not working on "V2 sticks" ! ).

Apologies for taking up your time, but I wasn’t aware this could be a possibility before purchasing. In India, there are no official ST suppliers who sell the Blue Pill development board—only the standalone MCUs are available. This makes it very difficult to know whether a seller is providing a genuine or fake MCU chip (especially since mine has laser engraving and the ST logo, which makes it look authentic).

It would be extremely helpful if ST could approve more authorized sellers in India, particularly for the Blue Pill development board. If that isn’t possible, I honestly feel the STM32F103C8T6 should no longer be sold, as it only creates unnecessary problems for first-time STM learners and drive the target market away.

Thank you very much for the reply! I tried it as you suggested and it didn't work:

I don't want to reply with this (I really want your help), but its okay you don't need to help me here as I am pretty sure that my stuff is fake (128kB flash and 20 kB SRAM) and even if we get it to work now, it will eventually end up with some other problem with the ADC or sensor interfacing protocols or something. I will use it with Arduino IDE for now and look for some other nucleo or discovery board.
Thanks again for your help though!!

The blue pill isn't an ST board, so you won't find any official ST supplier for it, India or otherwise. The vast majority of blue pill boards have non-ST parts on the board. I'm sure ST wishes they would stop being sold as well.

It would be really nice if ST took concrete steps to show that, anyways thank you!

How do you want ST to stop other people selling knock off boards? It's out of their control.

Unfortunately, pretty sure Blue-pill with STM32F103C8T6 chip is fake and we cannot control that market :(. 

Try to find one of the distributors: Digikey, Farnell, Mouser etc in India to purchase a Nucleo board.
