Hello @Xxiao.3​ ,

This behavior normally happens in Windows 10 if you have a Virtual Machine running that already uses the ports created by the board.

In these case, the ports are invisible for Windows because they are linked to the Virtual Machine.

I tried again on my Win10 and I got the same behavior than you.

  

If I "Disconnect" the two ports from the virtual machine, Windows can see one of them again:

  

(You have to close the debug window and open it again).

Hope it helps you,

Regards,

Kevin

Hi @Xxiao.3​ ,

Ok, do you still need help on this issue?

If you need help, please can you provide me a screenshot of your device manager in w10, especially the part about "Ports (COM & LPT)", with the board plugged without the VM.

There was a lot of changes between CubeIde v1.4 and v1.8, please can you try with intermediate version, like v1.7 or v1.6?

Regards,

Kevin

Hi @Xxiao.3​ ,

Ok, so now you have a serial port in the list. Please, what did you change to have something in the list?

Is COM7 the only possible choice of the list?

Please can you send me a screenshot of your device manager, the part "Ports (COM & LPT)", like this:

 

And please open a terminal on windows and use this command:

reg query HKLM\HARDWARE\DEVICEMAP\SERIALCOMM

and send me the traces. This command displays all the serial ports connected to Windows 10 even the one that are used by another application.

Regards,

Kevin

Hi @Xxiao.3​ 

I understand you have developed a board based onto STM15x and may be you have your own hardware implementation of the Linux console.

In STM32CubeIDE Linux console is discovered searching first STMicroelectronics or FTDI console, corresponding to STLink Virtual COM Port.

In your case I would recommend to force the console with menu:

Window > Preferences > STM32Cube > MPU Serial

enable Remove Filter and select your console.

Hope this help,

LudovicR
