Dear STM32CubeProgrammer Community, I hope you are all doing well.   Over the past months, you may have received an email from me, either through the STM32CubeProgrammer survey or on other topics like CSAT or Raspberry Pi support. First, I would like to thank you a lot for all your contributions and feedback, we highly appreciate them, your voice matters !   We’re currently working on improving STM32CubeProgrammer’s usability and would like to 1. reduce the number of repetitive / low added value actions you have to perform, and 2. provide you with clearer error messages.   We need your contributions to address priority scenarios.   Could you please share in the comments which improvements, use cases, or automated actions you would like to see in the tool to make your daily work easier ? This includes typical errors you often get that you think the tool could prevent or handle automatically, as well as any “why do I have to do this myself every time?” situation you e

Full installation is required for this to be done).

Dear community we are pleased to announce the new release of STM32CubeIDE for VSCode Breaking Changes Complete architecture redesign: The tool architecture has been split into three major building blocks with the purpose of creating a flexible, maintainable and updatable platform consisting of the following blocks: GUI, CLI tools and STM32 device support. GUI: The platform's single extension has been transformed into an extension pack, offering a more modular, updatable and flexible setup. CLI tools: A new bundle manager is enabling VS Code to download required CLI tools. This replaces the all-in-one STM32CubeCLT package. The bundle manager will provide developers flexibility, updatability and re-producibility in terms of CLI tooling. STM32 device support: The STM32 device support is decoupled from VS Code and sourced via CMSIS-PACK DFPs. Developers can now start using a new MCU without having to install a new STM32CubeCLT package.

We are pleased to announce that STM32CubeCLT 1.21.0 release is available.

Hello The version 1.12.0 of STM32CubeMonitor is available on st.com :  https://www.st.com/en/development-tools/stm32cubemonitor.html What are the main changes in this version ? Node-RED® updated to version 4.1.3. STM32 devices list updated. Software dependencies updated ( Electron, Chromium, nodeJS) The release note is available on ST.com : rn0119-stm32cubemonitor-release-v1120-stmicroelectronics.pdf  Do not hesitate to create new posts if you have any question. The STM32CubeMonitor team.

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) evolution will bring to you:  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 a

Updated post to reflect permanent fix Dear STM32CubeIDE user, Further to the recent STM32CubeIDE project creation issue, we would like to inform you that a solution is now available for you. This permanent fix applies to all STM32CubeIDE versions. Issue description When creating a new STM32 project in STM32CubeIDE, the “STM32Cube” radio button may have become unresponsive, blocking the “Next” button after the product selection screen. This prevented the project creation from being completed. Permanent fix You can apply this resolution to any STM32CubeIDE version, even if you applied the temporary workaround that we recently shared with you. Open STM32CubeIDE. Refresh the database.Go to Help > STM32Cube updater > Select “Check the Target selector Device Database Updates” Restart STM32CubeIDE If you deactivated the auto refresh function previously, you may wish to reactivate it for all your STM32Cube tools. Here is how to proceed: STM32CubeIDE:Go to Window > Preferences

Major change in SigningTool for STM32N6 in STM32CubeProgrammer v2.21.0 This release, we decided to change signing tool behavior to not automatically align the payload to 0x400 with padding bytes, since this is not necessary for other STM32 series. To sign binaries for STM32N6, please take care to add the -align or --align option to the signing tool command, example: >STM32_SigningTool_CLI.exe -bin Project.bin -nk -of 0x80000000 -t fsbl -o Project-trusted.bin -hv 2.3 -dump Project-trusted.bin -align
