Hello STTwo-32,

Please see the attached, ST-LINK V2.

This ST-LINK/V2 is very likely a counterfeit product, which can be seen from the completely old design of the box, which was changed long before 2024 (the date on the back). If the firmware cannot be updated using the light blue button ‘Firmware upgrade’, this ST-LINK/V2 cannot be used with the tools from STMicroelectronics.

Please see also: How to recognize a genuine ST-LINK/V2 versus a cloned one

Additionally: in the window with the debugger options, you ticked S/N, but the line does not show a S/N. Did you click Scan on the right?

Hello Peter,

The earlier issue is solved after I selected the shared setting and scanned again, I get a multi character s/n.

The logs show voltage is also good at 3.07V but the core ID could not be read and target could not be found.

I just realised my boot0 pin has been left floating on my custom board. Could this be causing the issue ?

Rest of the data clock supply and ground pins are correctly connected as I verified using a multimeter.

@initiativewater 

the firmware V2J45S7 is an old one, please upgrade to the most recent one (currently V2J46S7).

And please insert photos of your ST-LINK/V2 (back and front) as requested by @STTwo-32.

Regards
/Peter

Hi Peter, @AScha.3,

I tied BOOT0 to GND and upgraded the ST-LINK/V2 to V2J46S7 (see screenshot).
However, CubeProgrammer still fails to read the target:
