You might have counterfeit pods or chips. ST provides no support for those devices.

Check if the ST-LINK/V2 is viable directly under STM32 Cube Programmer. If it is then you need to check the settings of how the GDB Server is brought up and local/remote settings there.

this is the St link I am using.20231019_115558.jpg

Well that's definitely a third-party product and not an authentic ST-LINK

@Pal_555 You have saved money in the wrong place and should buy an original ST-LINK (if you buy cheap, you buy twice).

However, there are even ways to save money: if you buy a cheap NUCLEO-64, you can use the ST-LINK that is also included. Either break it off or disconnect the respective target MCU by removing the ST-LINK jumper. A NUCLEO-144 can also be used, but it is more expensive than a NUCLEO-64.

Good luck!
