I was trying to run a code in STM32CubeIDE v1.19.0. I have connected the MCU to my laptop via ST-LINK/V2 but when I tried running the program or updating the firmware on the ST-LINK/V2 I get the respective error messages:

I am new to STM32 development.

Could your ST-Link/V2 programmer be counterfeit?

Do you have a nucleo board or something else you could try?

Click on "Open in update mode". If the current firmware version is older than yours, proceed with update.

Then unplug and replug the USB cable and enjoy debugging.

Oh, I tried that... Seems like it was an issue with the ST-LINK that I purchased. As of now, I am programming the STM32 with a USB to TTL FTDI adapter. Thanks for the reply!

Thanks man, I think it was the problem with the ST-LINK, not any software issue. There was definitely a connection issue. I am using a USB to TTL adapter to program the STM32 rn. Thanks!
