Cube AI studio: build fails after editing .ioc file.

[chanchal94]

Whenever I am starting to make project  from scratch in STM32Cube AI studio, It gives complete structure with .ioc files as well as AI files, but as soon as I make changes in .ioc file and generate code after loading in CubeIDE, it changes the middlewares and build error comes . What is the solution for that? 

1. Should I first make the .ioc project and then make project in STM32Cube AI studio ( Import the existing project from STM32CubeMX or STM32Cube AI studio)

2. Another doubt is if I make project from preexisting .ioc, Do I need project in application mode for that as AI changes will work in application mode only ( but STM32N6 doesnt work without FSBL), what is your suggestion for Edge AI project building?

The error was :

Description Resource Path Location Type make: *** No rule to make target 'C:/Users/hp/.stm32cubeaistudio/workspace/Modified_STM32/Middlewares/ST/AI/Npu/ecloader.c', needed by 'Middlewares/ST/AI/Npu/ecloader.o'. Stop. Modified_STM32_Appli C/C++ Problem

Thanks & Regards

In the attached project I have not changed any default parameters, only configured ADC and required peripherals. Still the issue is same .

Hello,

You have more information in this topic:

STM32N6 FSBL explained - STMicroelectronics Community

Project generated by STM32Cube AI Studio follows the "eXecute-In-Place" (XIP) principle.

You need to avoid unchecking extra peripherals, especially XSPIs and EXTMEM / EXTMEM_LOADER.

I understand your point. However, prior to your response, I had already shared another project folder where I did not modify any of the configurations you mentioned. In that project, I only configured ADC, DMA, Timer, and USART, as these are essential for real-time detection in my application. Despite making only these changes, the build still failed.

I would like to understand the reason behind this issue.

If the tool does not allow configuration of the required peripherals, how can it be effectively used for edge AI applications?

Additionally, I have not modified any of the default settings or clock configuration in the project, yet the issue persists. I have not received a clear explanation for this behavior.

Kindly assist if possible, or please guide me to the appropriate domain if this falls outside your scope.

Thanks & Regards,
Chanchal

Hello @chanchal94 

Behavior is quite strange. I would say that it is unexpected since these files are managed by STM32Cube AI Studio and deleted by STM32CubeMX.

On my side I was not able to reproduce the issue since I maintained the IP "EXTMEM_LOADER" enabled in the project. It might be the error you are facing:

- STM32CubeMX created "Middlewares" folder

- STM32Cube AI Studio adds "Middlewares/ST/AI" folder

- STM32CubeMX deleted "Middlewares" folder because EXTMEM_LOADER was disabled and was the only "Middlewares" in your project

Could you retry on your side to see if, by maintaining EXTMEM_LOADER enabled, you still have this Middlewares folder ?

Best regards,

Yanis

@hamitiya you are talking about external mem loader in Middlewares & software Packs as shown in attached screenshot? With this also , I am facing the same issue.

Though previously also I had not enabled or disabled any such setting. but this time I checked the EXTMEM MANAGER in application also ( screenshot), But the problem is same.

Are you able to reproduce this issue in my zip file also or in the project you initiated from scratch?
