Issues with Code Generation in CubeMX for STM32N657X0H3Q (Non-Secure Mode).

[saikumar]

Hello,

I am new to the STM32N657x0H3Q MCU and trying to generate code from latest CubeMX with the following peripherals enabled:

UART
Ethernet
DCMI
USB
Non-secure region only
However, after generating the code and compiling it in Keli, I am encountering multiple errors. Additionally, CubeMX shows a warning:
"  - Generating AppNS project without AppS, compilation errors maybe generated."

I am trying to understand why this issue occurs.

Is there a strict limitation in this MCU series that requires defining a secure region?
If not, how can I properly generate code with only a non-secure region and avoid these errors?
Also, I am planning to buy the STM32N6570-DK board for my project.

thanks.....

One More Problem I Noticed   that.....

• I am enabling linked list for my USB streaming, but I noticed that the linked list initialization is not generated in the non-secure domain,  and files also be not generated
• If I enable the secure domain, the linked list part is generated inside the secure domain.
  And DCMI files are generated but , initialization part is not generated in both domains(secure and non_secure).
•  i have tried latest version of CubeMX and CubeIde. same problem is persist.
•  Why is this happening, and how can I force the linked list initialization to be generated in the non-secure domain?

Hello @saikumar ,

I confirm the issue related to the DCMI peripheral.

It has been reported to STM32CubeMX development team.

Internal ticket number:  204762 (This is an internal tracking number and is not accessible or usable by customer).

Thanks.

hello,

Mr . @Mahmoud Ben Romdhane .

Thank you for confirming the issue and reporting it to the development team.

Additionally, I would like to request clarification on why the LINKED_LIST files are not generated in the NON_SECURE domain. Could you please provide any insights or reasons for this behavior?
