STlink-V3E not detected in Device Manager

STM32L_user · ‎2025-08-05

Hi,

I have recently procured STM32L562E-DK Discovery kit. Having installed STM32 Cube IDE & STM32 Cube Programmer I tried to debug & run existing examples. However STLink is not getting detected on Windows 10 laptop. I have connected USB Type A to Micro B cable to CN17 connector. While the board powers up and is running default power measurement demo (out of box) I am unable to do any debugging/downloading of other example code.

I have tried using different USB cables & tried switching USB port on laptop. However there is no USB activity detected in Device manager. I have confirmed STLink driver installation & working through another STM32 board (Nucleo-64) where I am able to debug/program

Are there any switch/jumper settings on DK kit or do I need to connect USB Type C as well (already tried) to make the debugger work?

Any suggestions/inputs appreciated

Thanks

FAQ: Possible communication failure between STLINK-V3 and some recent computers

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

The CN17 connection is all you need for debugging. Is LD3 flashing red?

Sounds like you're using a power only USB cable.
