STM32CubeIDE 2.0.0 shows ioc files as text

vernture · ‎2025-11-30

I recently updated my stm32cubeide from 19 to 20.0.0 but the .ioc files of my existing projects open as text file not graphical as before.

How to fix it to work as before?

PS: I mistakenly chose VS-code target and it's not possible to delete the post and repost. I use STM32CubeIDE on Windows and my issue have nothing to do with vs-code (I don't use it whatsoever)

STM32CubeIDE v2.0.0 doesn't have STM32CubeMX built-in. You will need to download and install it separately and open the IOC file there. This is intended and included in the release notes.

I tried edit...move to STM32CubeIDE .

And yes, in IDE 2.0 need to have CubeMx to edit the .ioc file. No more integrated in IDE .

Hello @vernture ,

In order to open successfully the Ioc.File on STM32CubeIDE 2.0, you need to open it by default on the project folder with MicroXplorer for STM32Cube application.

Thanks.

As the others have said, CubeMX is no longer integrated in CubeIDE v2.0.0:

See this post (by @TDK ) on how to start an external editor from within the IDE.
