STM32CubeIDE 2.0.0 , .ioc file doesn't Open

IsmailYangui · ‎2026-02-12

Hello,

I am returning to STM32 development after about two years and I am preparing a new project that will handle multiple tasks using several peripherals.

I have installed STM32CubeIDE version 2.0.0. The installation completes without errors, and I am able to create a new STM32 project. However, after the project is created, the .ioc file does not open

Hello @IsmailYangui

From STM32CubIDE V2.0.0, the STM32CubeMX plug-in has been removed. So, the .ioc file is opened out of the STM32CubeIDE on the standalone version of the STM32CubeMX.

see STM32CubeIDE 2.0.0 released.

CubeMX (which handles IOC files) is now purely a standalone app - no longer integrated in CubeIDE v2.0.0:

For discussion, see: IDE Version 2.0.0 - why remove MX ?

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.
