Question

ST-LINK2 on Windows 11

I have worked with ST-LINK/2 on Windows 10 for several years. I must upgrade to Windows 11 because Windows 10 support ended a few months ago. Today, I tried to program the WIO E5 Mini microcontroller, but I found it's impossible because there's no driver for it on my computer.
I found some information that I should install version 9 of that driver. I downloaded it from the original STM source and ran it, but nothing changed. Is till don't see this driver among my devices. Installation ended without any error. 

Is there anybody who can point out what I am missing?

You mix apples with ... WIO require external STLINK connected to SWD ...

Onboard USB is UART bridge nothink todo with STLINK... Require driver for CP uart bridge.

Specify what is your connection problem.?

I can't upgrade the firmware because of it:

I attached my microcontroller to USB as usual (under W10). As you can see, I use SWD. But the programmer doesn't see it.

A working st-link.

Has nothing to do with the CP2102 , uart bridge.

Show a pic of your st-link V2 , then we know what you have.

It's the same configuration that has worked under W10. The only change was from W10 to W11.

As you can see, there is no target voltage, and the LED doesn't blink when attached to the USB.

As YOU can see on the CubeProgrammer :

NO st-link connected.

So: you have a st-link at all ? connect it to USB.

As @AScha.3 said, please show a photo of your ST-Link - you seem to be confusing it with a USB-to-UART adaptor.

 

To start with, check that you have a genuine ST-Link:

How to recognize a genuine ST-LINK/V2 versus a cloned one

 

Then see:

How to solve debugger connection issues

And:

How to solve connection errors when connecting and programming the STM32 target board.

 

A genuine ST-Link should work fine on Windows 11.

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.

Here are the possibilities:

If nothing happens in device manager when the device is connected, likely the cable is bad.

I have used the last working pin connections between ST-LINK/2 device and the WIO device, and for now, I'm a little bit closer, I think.
I had such messages earlier, and I recall that there is some kind of magic how to mange it:


20:17:58 : ST-LINK SN : 50FF6B067182575134150187
20:17:58 : ST-LINK FW : V2J45S7
20:17:58 : Board : --
20:17:58 : Voltage : 0.00V
20:17:58 : Error: Unable to get core ID
20:17:58 : Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

I don't understand how there can be such a small voltage measured by the ST-LINK/2 device. I checked the connections between devices twice, and everything looks fine.

>Voltage : 0.00V

means -> you have no power (3v3) at the target, your wio...

connect the 3v3 to wio VDD.
