I designed PCB for STM8L052C6 and programming using ST-LINK V2 mini. I am using 3.3v GND SWIM NRST pins but is not programming. I have selected STM8L052C6 in STVP and Selected STM8L052C6 compatible compiled file. Still i am getting problem. I am directly using these four pins with ST_LINK V2. Kindly help me to solve the issue. Thanks in advance..
