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

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

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