Starting from the release in November 2025, STM32CubeIDE and STM32CubeMX will be available exclusively in their standalone versions.
STM32CubeMX will no longer be integrated inside STM32CubeIDE. Instead, the two tools will be interoperable in the same way as with IAR EWARM, Keil MDK-ARM, and STM32Cube for VS Code.
The current integration of these two tools may seem compelling in the early prototyping phases of a project. But the integration leads to heavy/poor performance, stability issues across OSes and monolithic updates. It is time for STM32CubeIDE to go back to its roots and focus on Edit / Compile / debug.
What the STM32CubeIDE (2.0) evolutionwill bringtoyou:
Greater flexibility in code development thanks to purpose-built, standalone tools.
Updateability: Offering the possibility to use any version of STM32CubeIDE with any version of STM32CubeMX. Separating STM32CubeMX and STM32CubeIDE allows developers to update each tool independently,lowering risks and increasing flexibility.
Project type flexibility: Allowing STM32CubeIDE users to also leverage STM32CubeMX-generated Makefile projects, and CMake projects for additional projectflexibility.
Harmonized workflows: Interoperability instead of integration harmonizes the workflows between STM32CubeMX and all IDEs.
Better usability and performance for faster project completion:
Faster tool launch and lower PC resource requirements.
Increased stability, particularly on Linux and macOS system.
No log-in required inside STM32CubeIDE.
Next steps: what is the impact for STM32 developers?
STM32CubeIDE 2.0 will be available as an installer package from st.com.
Previous versions of STM32CubeIDE and STM32CubeMX will still be available to download from st.com.
Updating existing installations will require adding a new Eclipse P2 update site to eliminate unintended/unaware updates.
ST will continue providing technical support on old versions.
On-going STM32 projects will not be impacted by this update.
However, opening an existing project with a newer version of STM32CubeMX may update your project, depending on STM32Cube firmware used. This issue is not related to the STM32CubeIDE and STM32CubeMX tool split.
Double-clicking on the ioc-file from inside STM32CubeIDE, will launch the standalone STM32CubeMX tool if you already have the tool installed.
Update 2025-12-15: Adding link to CubeIDE 2.0.0 video tutorial
We are confident that this update will bring significant long-term benefits to your development process. Our support team is here to assist you during this transition.
A Danish man has a YouTube channel STM32World, he has been making STMCubeIDE tutorials for a long time. He is very informative and provides all the code.
Since Version 2.0.0 came out he has made some additional videos, start with this one:
