Problems with STLink

I’ve bought a cheap Chinese version of ST Link/V2 but having some problems to put it to work. I’ve installed latest STM drivers, got it under Universal Serial Bus device branch as STM32 STLink but it refuses to work. After checking of event’s log I’ve found this:

Device USB\VID_0483&PID_3748\6&418b671&0&3 was not migrated due to partial or ambiguous match.

Last Device Instance Id: USB\VID_1C4F&PID_0034\6&271a58ce&0&3
Class Guid: {745A17A0-74D3-11D0-B6FE-00A0C90F57DA}
Location Path: PCIROOT(0)#PCI(1A00)#USBROOT(0)#USB(1)#USB(3)
Migration Rank: 0xF000FFFFFFFF0023
Present: false
Status: 0xC0000719

Have you tried this?

Thank you for the answer, stevestrong. I didn’t but I’ve previously understood that I can flash microcontroller, not from STM32 ST-LINK Utility but from STVP. I’ve updated device with your patch after that and it still says that “was not migrated due to partial or ambiguous match”.

What could be the problem with ST-Link utility in my case?

What about this – the latest, it seems

You have a vid/pid mismatch. 3748 vs 374B.

uh? i just plugged in my usb st/link block, blue/white already in
so lsub gives

Missing infos:
– which core do you use (Arduino_STM32, STM32DUINO, or STM32GENERIC)?
– which board do you use?
– which IDE do you use? Arduino? Which version?

– What is STVP?

– if you can flash with STLink utility it means you have the right drivers installed, so it must be something wrong with the flashing utility of the used core. So go back and answer question 1. And post here the full message you get from Arduino IDE, if you use it.

– STLink DOES NOT WORK AS SERIAL PORT !!!
You have to connect a USB cable to the micro USB slot (blue pill) in order to have USB serial port.

– STLink DOES NOT WORK AS SERIAL PORT !!!

it depends. some v1 and all v2 and newer ones support serial comm: https://dannyelectronics.wordpress.com/ … link-v2-1/

stvp is a st standalone programmer.

how to solve that?

1. answered below
2. Blue Pill. Tried also with StM8 board
3, I’ve created some code from Arduino IDE but also from CxSTM32

– What is STVP?
STLink Visual Programmer

I am using hex file, not uploading code from Arduino IDE.

I didn’t use it as serial port. Thank you for advice.

OK, so it seems that you are not uploading with Arduinoi IDE.

As you may know, this forum is mainly dealing with Arduino for STM32.

If you use your own tool chain, you are on your own.
You could still get some help if you tell us more how exactly your toolchain does look like.
And maybe you give us some example files to reproduce your problem.

I know that it is related with Arduino but it is the same tool (STLink) used for programming of all STM boarda. I’ve expected that someone could explain how to manage to solve my problem with drivers. In the meantime I’ve realized that my device is fine (although “was not migrated “) but the problem is related with work of ST-Link utility software. Now I’m expecting that people working with STM32 boards could help with this. In any case it is not bad to learn something new and useful even it isn’t directly related with Arduino, right?

I opened Win10 x64 in Oracle VM VirtualBox.
Plugged in the stlink cheapo dongle (USB3.0).
Win10 found the stlink device, tried to install the driver, no driver found, I saw st-link icon with yellow triangle in the dev manager.
Dongle left plugged in.
Took a short nap.
Downloaded ST_Link Utility v 4.1.0.
Installed the ST_Link Utility, it installed the driver as well, no problem.
I get (PID is 3748 – eight at the end):

I use Arduino on Win 10 x64, and have no problems with STLink V2 (clone).
How do you build your project? Which utility/file/script do u use to upload?

I agree, but if don’t show us this “something new and useful” we are not able to help you.
