STM32CubeIDE STM32Cube project creation issue

Semer CHERNI · ‎2025-07-16

Description

In STM32CubeIDE version 1.18.1 and older, after selecting any MCU or MPU when creating a new project, the STM32Cube option becomes greyed out. This means only empty projects can be created, and STM32CubeMX initialization is not available from within STM32CubeIDE.

How to Reproduce

Open STM32CubeIDE (v1.18.1 or older)
Create a new STM32 project
Select any MCU or MPU
Notice the STM32Cube option is disabled

Expected vs Actual

Expected: STM32Cube option enabled for STM32CubeMX-based project creation
Actual: STM32Cube option greyed out; only empty projects are possible to create

Current Status

This issue is under investigation and a solution will be published in the near future.

For reference, some recent posts which seem to be encountering this issue:

v1.16.0: STM32Cube Option disabled during project creation; No .ioc File Generated

stm32 targeted project type is empty and its not generating .ioc file

CubeIDE 18.1 does not create CubeMX project - no .ioc file

ioc file not generating

.ioc file generation

No .ioc file generated; FPU not initialised

PS:

Possibly another: NUCLEO-H743ZI2 board not supported in STM32CubeIDE - Obsolete

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.
