ST-Link V2 can't connect on Windows 10 (Version 1809)

[MGrze]

I installed the driver for the ST-LINK V2 on Windows 10 (STSW-LINK009). The Installation was successful. Unfortunatelly the device can't connect to the USB port and is blinking red. I even can't find the driver in the Device Manager in Windows. The software tools from st can't also find any device. I've tried it on three computers, with the same result.

I am trying to connnect the MxChip IoT DevKit and one section of the getting started guide (https://microsoft.github.io/azure-iot-developer-kit/docs/get-started/) includes installing the ST-LINK V2 (STSW-LINK009). It looks like it installs correctly but when connecting my device no STMicroelectronics port appears per the getting started guide. I am also on Win10 and wonder if I have the same issue. I do not see the driver anywhere in Device Manager either. I have tried it on two computers.

Hello,

Try to upgrade the ST-Link firmware through ST-Link Utility: go to ST-LINK>firmware update,  Then disconnect and connect your board.

Otherwhise, try with "STM32CubeProg" software for programming STM32 products

Please tell me if that solve the issue.

Kind Regards,

Imen

Please provide a download link for the ST-Link Utility. Also how will my computer detect the device in the Utility if the driver for the ST-LINK V2 on Windows 10 (STSW-LINK009) is not working?

After installing the ST-LINK V2 on Windows 10 (STSW-LINK009) should there be an entry in the device manager under USB Controllers for the STM Device? My computer did not have any entries after that install. See image below.

Hi, by me ist the USB Driver also not visible. Therefore I think the Driver is not installed, even though the software confirms the driver Installation.

I still don't see my device in the "STM32CubeProg".

I'll get tomorrow a second device to check it..

Hi, I've got today the second ST-Link/V2. It works as expected. The first device was broken, even though it was new!

Thanks for support!

[JBrin]

So your solution was related to faulty hardware. Is that correct? Does the USB driver now show up in the Device Manager with the new hardware?

[MGrze]

Hi Jeff, the device Manager in Windows 10 shows now an additional point "USB-Devices" - "STM32 STLink". I didn't install any additional drivers. Just connected the new ST-Link/V2 and it works! The red led is lightening, not blinking. The old, broken device showed only blinking red light.

I'm writing just to inform everybody has that issue and check to find an answer in this topic. I solved that problem with replacing the micro-b cable with another one within 3 times try. It does not accept any cable to drive the debugger.

Thanks, your tip saved me

I have exactly the same problems.

So, I am going to buy a new nucleo board.

Can somebody give me advice where to buy it in Europe?

I there a company where I can test my boards? What is the responsibility of Stmicroelectronics?

Thanks.

you can buy here:

Thanks AScha.3

I've purchased a second new Nucleo-G071RB board and this one also does not connect to my Windows PC: blinking red LED and no entry in the Device Manager. I've use several cable etc. etc.

I have purchased another board, the Nucleo-L476RG. After connect the cable, it worked as it should be.

Where can I find a guide or book that completely covers this underestimated subject?

I want to pay for the solution :)

Robert Schuurmans.

Hello Robert,

i just can say: no solution, because all Nucleo or -dev board working as they should, from beginning on /first plug-in;

so if your nuc-g071 board is not recognized by the pc: try other cable / position to plug in / other pc .

if no reaction - board defect, return . if reaction, but "unknown..." or "defective.." , try other cable and plug.

just on some old windows systems you might need install st-link system driver .

if you start CubeProgrammer , you should see any st-link thats connected to pc . try this first.

Hi,

My Stlink has been working successfully until yesterday but today when plugged in all I get is a flashing light. The device is not being detected at all. This computer is dual boot with Linux and Windows 10 and the result is the same when booting in either OS.

What is strange is that this dongle is detected properly on another computer having the the same Linux OS as the first one so the dongle cannot be faulty. The USB port on the first computer works fine with my printer so it is not that either. upgarding to stsw-link0009 had no effect either.

 

Any ideas please?

- try another cable and other socket

- on linux -> shell -> demsg  : what it tells about, when st-link plugged in ( demsg again )?
