Which software do I need to install to start with STM32N6570-DK?

[Anhem]

I am a newbie with STM32N6570-DK.

My target is to deploy AI model on this board. Which software do I need to install to start with STM32N6570-DK? I means that all softwares.

Thank you.

Hi Julian and Anhem,

I am also using stm32n6570-dk and using stm32ai-model-zoo.

I have encountered many errors and solved all of them. 
One with gpu limits.

One with stedgeai.exe file path.
Stm32-programmer-CLI.exe system variable addition.

now after that I am running this command but I am getting error at the end of that.

Error:

Can you both help me. There is this file is missing. "DK_GettingStarted_ImageClassification_signed.bin""

Thanks in advance.

Hello @Khonshu,

This errors is triggered when the model zoo fails to build your project in STM32CubeIDE.

For example, if your model is too big, the application will not build, and so the .bin will not be generated triggering the error.

When you do a deploy, the model zoo is using the example application in application_code\image_classification\STM32N6\Application\STM32N6570-DK\STM32CubeIDE

Could you please open the project in STM32CubeIDE, build the project and tell me the error you get.

If you could also maybe share your model and user_config.yaml. Thanks

Have a good day,

Julian

Hi, 

Can you tell me, when I deplay the model earlier and got error. From that moment my demo is not working on the stm32n6570-dk and screen is also off. Like there is no backled on. Nothing. I set the  Boot 0 and Boot 1 to right.

Why is this happening? 

Can you guide me.

Is it like after flashing the demo is just gone?

And I will post about the project open in StmCubeIDE.

Thanks

Khonshu

Hello @Khonshu,

The N6 does not have internal flash. 

When using Model zoo, the application is built and flashed in internal ram directly.

So, if you restart the board, because the application is in flash, you are indeed loose the application.

To have an application that stays when you restart, with the N6, you need to store the application in external flash and configure a first stage boot loader to load the application in internal flash before running the application when booting.

You can read more here:

https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206 

In the case of model zoo, the application flashed as part of the deployment operation mode, are the getting started application. In the documentation you can read about how to either deploy it in ram directly or do what I described, to flash a FSBL and the Application + weights. For example, with image classification:

STM32N6-GettingStarted-ImageClassification/Doc/Deploy-your-tflite-Model-STM32N6570-DK.md at main · STMicroelectronics/STM32N6-GettingStarted-ImageClassification · GitHub

(You can also look at the other doc in the same folder).

Have a good day,

Julian
