Your Voice Matters : Help Us Improve STM32CubeProgrammer Usability & Error Messages

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

STM32CubeIDE for Visual Studio Code (MCUs)

New STM32CubeIDE for Visual Studio Code 3.8.0 released

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.

STM32CubeIDE 2.0 release - early heads-up!

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.

SigningTool for STM32N6 in STM32CubeProgrammer v2.21.0

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

Test STM-UAT4

Hello,This is for test BOOT1 jumper is set to HIGH for development (DEV boot mode) I have a simple LED blink application built with GPIO configured in the FSBL context The code runs as expected in DEV mode (debug mode of STM32CubeIDE) I then flashed the signed binary in external memory using STM32CubeProgrammer and External Memory loader for Nucleo-N6 board at address 0x70000000. Then, I switched BOOT-1 jumper to LOW and reset the board. The code runs as expected from external memory Edit: new test 😀

How can I use C++ with the generated code from CubeMX in the STM32CubeIDE for Visual Studio Code?

In STM32CubeIDE, I can compile C++ code in the project. The CMake file generated for the VSCode extension doesn't work with C++. Is there a way to use C++ code with less hassle than trying to get around this by hand?

Dark mode theme for STM32CubeMX

With the recent split of STM32CubeIDE and STM32CubeMX, I'd like to propose a dark mode option be added to STM32CubeMX.In consideration of the competing priorities for STM's software development team, I have two suggestions for how this proposal could be implemented:The first suggestion is the typical route: STM's in-house software development team add the UI theming and inputs to switch between dark and light mode.The second suggestion is less typical: make STM32CubeMX open source and let the larger software community assist with adding dark mode. Perhaps the source could be placed alongside other repositories in STM's current GitHub account....The benefits of adding such an option would be as follows:Consistency with STM32CubeIDE, from which STM32CubeMX was split from (STM32CubeIDE already has a dark mode)Consistency with the vast majority of other software in the industryConsistency with what has become a common user experience across operating systems, browsers, and setups in g

STM32N6570-DK: Missing Support for USB PHY Clock Sources

This thread is split from this old discussion @FBL  RCC_USBPHY1REFCLKSOURCE_OTGPHY1 and RCC_USBOTGHS1CLKSOURCE_HSE_DIV2 are missing in generated code I created a simple FSBL application that is jump to the AppliThe Appli is using the same approach (SW solution) like it was implemented inside "Ux_Device_CDC_ACM" example, (it was migrated in to the Appli)Currently, during debug, I am observing the same issue like it was described before (stuck in USB_CoreReset() during checking the "USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST" )The solution, that you provided, it looks like it does not working anymore by using the latest Cube_FW and generated compilation errors (no defines for the RCC_USBPHY1REFCLKSOURCE_OTGPHY1 and RCC_USBOTGHS1CLKSOURCE_HSE_DIV2).Could you please provide a solution (it would be better to see an example) how to solve this issue base on the latest MXCube and STM32CubeIDE versions.

Starting a new project with an existing ioc2 file

gil_dobjanschiAssociate II

STM32CubeMX2 (MCUs)

Hello, I would like to learn if there is an easy way in STM32CubeMX2 to start a new project with an existing ioc2 file. It seems that the only way I can do this is make a copy of the ioc2 file, do a text find and replace for the name of the project and reopen the project in MX2.In essence, I like to start a project from a working ioc2 configuration and modify it to work on a fork of the project. I don't want to recreate a complex configuration from scratch because I found the hard way that it is easy to make mistakes or to omit something. Thank you,-Gil

CubeMX Memory Management and high-cycle capable Flash region.

HiAccording to the reference manual the high-cycle capable Flash of a STM32H562 is mapped to the address 0x0900_0000 to 0x0901_7FFF. The Memory Management Tool of CubeMX does not allow me to generate a Region in this address range (see Error below). Is this correct or should CubeMX not allow the generation of a memory region in this range? The Flash Option Byte was configured for the use of the high-cycle Flash.As a work around I can of course manually edit the linker script.I use STM32CubeMX Version 6.14 with the Firmware Package V1.5.0 to generate a STM32CubeIDE project on Windows 11.

STM32H743 - Setting External Event source for HRTIM Timer in CubeMX ?

There are 4 external events that can be chosen to trigger and reset individual counters of each HRTIM timer unit in STM32H743 MCU. CubeMX shows those events once the Event Configuration is chosen "Enabled" . Yet only Source 1 is active (allowed to be chosen) but the Source 3 that I need to connect internally to the TIM2 TRGO output is inactive (cannot be chosen) . Why? My attempts to use AI got strange results - after searching the STM documents AI concluded that CubeMX is limited , it allows only external on-pin connections and any internal connections must be manually coded in addition to the generated code. If it is so then why does CubeMX show those other options yet does not allow to choose them? Or is there way to activate those options ?Please anybody give me suggestion.Note: the STM32CubeMX is the latest downloaded and installed yesterday. The MCU library pack is also current.
