Dear @hafiqat_ ,

 

You need just to connect/hook the SWD connector signals from the ST-link to the target : VDD, Ground , SWD and CLK

Hope it helps you , pay attention on the orientation of the cable to not Have short circuit on both VDD/Ground .

Do I just need to solder the contacts to the stlink? Without using an adapter?
