STM32N6570-DK not showing COM port in STM32Cube.AI Studio

[Duc]

Hi everyone,

I’m having an issue connecting my STM32N6570-DK board to STM32Cube.AI Studio.

The board is detected correctly by my computer, and I can see the COM port in Windows Device Manager. However, when I open STM32Cube.AI Studio and go to Board Settings, the COM port list is empty, so I cannot select the board.

Here is what I have already checked:

• The board is connected via USB and recognized by Windows.

• The COM port appears normally in Device Manager.

• I set the board to DEV mode with Switch 1 = HIGH.

• I restarted STM32Cube.AI Studio and reconnected the board.

Despite this, the COM port does not appear in the Board Settings dropdown in STM32Cube.AI Studio.

Has anyone encountered this issue before with the STM32N6570-DK or similar boards?
Is there any additional configuration or driver required for STM32Cube.AI Studio to detect the COM port?

Any help would be greatly appreciated. Thanks!

Best regards.

Hello @Duc 

Board can not appear if STM32CubeProgrammer is not able to connect to it.

Could you verify in your settings if the STM32CubeProgrammer installation path resolves to an executable from a version greater than 2.19.0 ? 

I will suggest you, if not, to:

- Install latest version of STM32CubeProg here: STM32CubeProg | Software - STMicroelectronics

- Upgrade ST-Link F/W

- Change the tool path to your new installation

Best regards,

Hi @hamitiya,

Thank you for your advice. Based on your reply, I was able to identify the root of the problem. I had two different versions of STM32CubeProgrammer installed one was the latest version and the other was an older version used for MATLAB code generation.

STM32Cube.AI Studio was targeting the older version instead of the latest one. After updating the path to point to the latest version, everything worked correctly.

Hello @Duc 

Thanks for your feedback.

Based on that we will try to fix it in a future release to better detect tools version.

Best regards,
