Hi there,

Could anyone advise how to setup STM32CudeIDE to debug my custom board using ST Link V2 ?

That's almost certainly going to be a fake ST-Link:

Do yourself a favour, and get a genuine ST-Link...

Connect SWD pins to programmer.

Ensure board is powered.

Hit debug.

Not forgetting V_target and GND.

@HMSEdinburge Also connecting NRST is highly recommended.
