St link v2 swim connection

[Briez]

Recently I purchased St link v2 programmer online and tried to program my stm8 device but ST Visual Programmer displays an error that please cheak your swim cable connection. I am doing my connection like,
Vdd (IC) -> 5V (ST LINK)
Vss (IC) -> GND (ST LINK)
SWIM (IC) -> SWIM (ST LINK)
NRST (IC) ->Swim_RESET (ST LINK)

My target device is unpowered externally. Can anyone tell me what can be the issue?

According to the ST's STLink v2 manual, the 4-pin swim connectors order is as follows:

Pin 1: Vdd
Pin 2: Data/SWIM
Pin 3: Vss
Pin 4: Reset

You may have Vss and Data/SWIM reversed.

My board only contains microcontroller ic. Is there crystal required on board to program it?

I connected cryatal on osc pins but still I cant communicate with device. I externally powered also but couldn't program it.
