So the ST-Link is working fine, but it can't find any target device to connect to.

Please give details of your target (what chip, what board, etc), and how you have connected it to your ST-Link.

What ST-Link are you using?

Please see the posting tips:

Hello @Saranya_2003 ,

Could you please try these points:

1. Check that STLinkServer is installed or install it from this site.
2. When you plug the board to the PC, It should enumerate as a STLink debug probe in device manager.
3. Upgrade STLink firmware.
4. Check the wiring cable and find one you know for sure is a data cable.

Thanks,

Rim

Your hardware is not working.

Focus on your hardware, how it's powered, how it's connected, etc.

What board(s) and MCU are you talking about.

Lacking detail of what its attached too.
