Missing .ioc File in STM32Cube Template Project for STM32N6570-DK board

athern27 · ‎2025-02-13

Hi ,
I was going through the template_fsbl_xip project located at:


STM32Cube_FW_N6_V1.0.0/Projects/STM32N6570-DK/Templates

However, I noticed that this project does not contain an .ioc file, whereas other examples like GPIO_IOToggle and several others do include one.

My question is:

Is this an oversight, or was it intentionally left out?
If it was intentional, how can I create an .ioc file for this template as I would like to start my project using STM32CubeMX and I would like to use external flash and ram present on STM32N6570-DK board.

Hello @athern27

Infact, some projects/templates are not based on the STM32CubeMX. So, they don’t come with a .ioc file. If you want to recreate them based on the STM32CubeMX, you can do that on a new project. First, you have to start your project on CubeMX. Try to set the configurations available on the STM32CubeMX and generate your code. Then, set the other parts of code manually on your generated project.

Best Regards.

Thanks for the fast reply,
So can you please tell me if there is any example available which uses external flash and also contains .ioc file as all of the HAL examples I saw use internal RAM for their execution.

All ST examples are available on the STM32CubeN6. There is not other examples. Have a look at the AN6197 to have an idea about the available projects and the projects that have or not a . IOC file.

Best Regards.

Hello @athern27

You can refer to the example located at Projects/STM32H7S78-DK/Templates/Template_XIP in the STM32CubeH7RS firmware package to get inspired from.

As @STTwo-32 said, not all examples have a .ioc file.

See:

To identify which examples do have a .ioc file, see:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
