STM32N6570-DK model zoo delpoyment error

[wwnsok2]

I followed the steps in the link below and then ran main.py, but I encountered the following error. I don’t know how to resolve it. I also set the BOOT0 and BOOT1 switches on the board, but I still get the same result.

Hello @wwnsok2 ,

It seems to be a STM32CubeProgrammer Error.

What version of STM32CubeIDE and STM32CubeProgrammer are you using?

What is your OS?

Can you also please send me your user_config.yaml

Have a good day

Julian

[wwnsok2]

i'm using on

STM32CubeIDE 1.18.0

STM32CubeProgrammer 2.19.0

Windows 11

Since attaching .yaml files is not supported, I have converted it to a .zip file and attached it.

[Julian E.]

Thanks for the information.

Can you try to open STM32CubeProgrammer, plug your board and click connect

Do you get an error?

Do you use a USB C cable to USB C? 

I have seen other people with other board having the same issue because of power supply. 

In the case of the N6, I've heard about issue if not using USB C to USB C.

Please use formatting in your original post.

No specific language (for instance terminal output):

A programming specific language (such as C/C++):

When I press the "Connect" button in STM32Cube Programmer, the connection is established. The model name is also detectable. I’ve updated the ST-Link driver firmware, but the same message still appears. Additionally, I’ve tried both a C-to-C cable and a C-to-A cable, but both produce the same result. 

Also, the boot switch is set according to the manual. thank you.

Hello @wwnsok2 ,

Can you go to your model zoo folder then /application_code. 

Next got to the folder of the use case you are working with (image classif, object detection etc)

Then /STM32N6/STM32CubeIDE and open .project 

Set the N6 boot pins to the right and connect it to the pc.

Click Build then run on stm32CubeIDE.

If everything works, set the pins to the left this time and unplug/plug the N6.

Let me know how it went.

Julian

[wwnsok2]

thank you very much it works very well.

Hello! The build was successful after following your instructions. However, when I set the N6 startup pins to the right side and connected it to the PC, the screen flickered once and then turned black. Meanwhile, both LD3 and LD4 turned red.

Hello @llcc,

Do you use a USB C to USB C cable?

What model are you using?

Have a good day,

Julian
