ST-LINK on STM32N6570-DK board warning 0x486 when connecting on STM32CubeProgrammer

[Avgerinos]

Hello

As I am trying to connect the STM32N6570-DK board on the STM32CubeProgrammer, initially the STM32CubeProgrammer recognises my device as in the following picture:

When I press Connect on the STM32CubeProgrammer I get a
warning: Connection to device 0x486 is lost
as in the following picture:

and then an error that says Data read fail
as in the following picture:

I am using a MacBook Air M3, 2024, but even on windows (running on a virtual machine) I get the same error on the STM32CubeProgrammer windows version.

Is there a way to overcome this issue? What could be the cause?

Thank you

Hello @Avgerinos 

I managed to get all STM32Cube tools working on Mac OS M1 and M2 without any issues. I don't have M3 hardware.

1. Start with connecting the STM32N6570-DK STLinkV3 (CN8) to your Mac, and check if and how it recognizes the USB device (see the link below) https://www.youtube.com/watch?v=aXd7FsjcIpI
2. Confirm that you are using the latest version STM32CubeProgrammer v2.19.0?
3. On Mac computer, Update Rosetta: $> softwareupdate --install-rosetta
4. Update the STLink Firmware to V3J16M7 of your STM32N6570-DK.
5. Ensure that your board is in DEV_BOOT (BOOT1=H) and that the Red LED2 is on after a RESET.
6. Try changing the ST-LINK configuration to Mode=Hot plug and Reset Mode=Software reset.
7. Change the USB cable.
8. Try on another computer.

Good luck.

Romain,
