Cannot connect to Blue Pill using STM32CubeProgrammer with ST-LINK/V2 on Windows 10

[GMan1]

Hello!

I have Blue Pill board and ST-LINK/V2 programmer. When I open STM32CubeProgrammer on Windows 10, my ST-LINK is detected properly but nothing happens when clicking on connect. No error messages, nothing. I can click all day and nothing. At the same time if I connect my ST-LINK to an Linux machine, STM32CubeProgrammer connects to my Blue pill without any problems. I have found couple of threads on Google with similar issue, but they seem outdated and are not working for me.

I have tried re-installing JRE multiple times, but nothing changes. I hope you guys could help me, as I am really willing to start learning STM32.

Does it detect the ST-Link (target voltage, firmware version, serial number)?

Does the UI respond to the clip at all? Can you manipulate other buttons and controls?

Try ST-Link Utility.

Thanks for your answer!

As I wrote in the opening post, ST-LINK is detected - it shows target voltage and Firmware version. Only the Serial Number is weird - it shows only one letter "U". I just tried the ST-Link Utility. It shows much longer serial number and it successfully connects to the target. I guess, I could stick to that, also it would be great to understand what is wrong with the Cube Programmer.

Are you using a knock-off programmer as well? If "ST-LINK is detected properly," which it doesn't quite sound like, see if you can upgrade firmware.
