Target unknown error 32 in STM32N6

[chanchal94]

I am working with STM32N6570-DK. My code is building fine , suddenly a hard fault has started coming. I have tried updating firmware, resetting the board, unplugging and reconnecting it, But debugger is getting stopped after sometime.

Is your code going into a low-power mode, and/or reconfiguring the debug pins?

Hello @chanchal94 

Let me thank you for posting.

I recommend that you take a look at this Knowledge Article and this Application Note.

They describe how to get started with projects based on STM32N6 microcontrollers in the STMicroelectronics
STM32CubeIDE integrated development environment.

Thanks.

No my code does not have any low power mode.

Below is my project structure. I have FSBL included in it but my whole project is in application main.c . Do I have to take care of any extra settings of debugger while debugging the application code? 
While in this case if I try to debug FSBL first that is also not working. Which parameters should I recheck again.
From Example - GPIO toggle was working fine.

In this knowledge article at ST community, I tried loading this Template file, If I am working on my FSBL+Application project .

1) In debug configuration settings , What bin file should I use, the same which has been used in template example or from our project and how to find its address?

2) Debug as in my case should halt at main only (as I am working in main of application only)

3) Should I start debugging from FSBL or application directly ( My whole program is in application main ())
I have attached the screenshot of template page and other is my application debug configuration settings , Can you tell these two queries?

@Mahmoud Ben Romdhane I followed the article https://community.st.com/t5/stm32-mcus/how-to-build-an-ai-application-from-scratch-on-the-stm32n6570-dk/ta-p/825591  as you told, It helped in removing the  Target unknown error 32, But I am still stuck as when I debug application it jumps to somewhere outside the code. I know less about memory mappings of STM32N6, Can you help? I am attaching fours steps that is happening while debugging of application. 

Thanks & Regards

Hello @@chanchal94 

Further to your comment, I recommend that you connect the board with STM32CubeProgrammer and erase the flash memory before launching the debug session.

I will be waiting for your feedback.

Thanks.

Hello @Mahmoud Ben Romdhane 
I tried connecting board with STM32CubeProgrammer and complete mass erase. It removed this last 0x0 breakpoint. But still the problem is same.

Hello @chanchal94 

Could you provide your STM32CubeIDE project.

Thanks.
