How to setup STM32CubdeIDE using ST Link V2 Debugger

HMSEdinburge · ‎2025-10-07

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...

You can read how to set up an ST-Link in CubeIDE:

Connect SWD pins to programmer.

Ensure board is powered.

Hit debug.

Not forgetting V_target and GND.

@HMSEdinburge Also connecting NRST is highly recommended.

Hi Dude, its genuine STLink V2, cost $40++

Hi All, can the ST Link V2 be used for debugging? I m keep getting these errors on STM32CudeIDE, although i can use STLink Utility to download the code?

Error in initializing ST-LINK device.

Reason: ST-LINK: Could not verify ST device! Abort connection.

Of course it can - that's its key function!

The ST-Link Utility is long obsolete - STM32CubeProgrammer is the replacement.

You haven't said what STM32 chip you're using - the Obsolete Utility won't support recent chips.

A fake/clone ST-Link could also cause problems.

Again, see: How to recognize a genuine ST-LINK/V2 versus a cloned one.

This typically happens with non-genuine devices.

See if it works with the standalone STM32CubeProgrammer.

yes it works on STM32Cube Programmer, i can download code on the board

hi Andrew, i tried the STMCude Programmer, it works perfectly... board is a blue pill, STM32F103, guess it must be a Chinese clone...

I happen to have the H753 Nucleo and H750 DISCO board, could you advise how to test the STLink V2 on these 2 boards? I m pretty sure the STlink V2 is a genuine from STM!
