STM32CubeIDE (MCUs)

Hello,if you are using macOS and STM32CubeIDE and need it productively you should currently refrain updating your macOS. Due to a bug in Eclipse (https://github.com/eclipse-platform/eclipse.platform.swt/issues/2621) text selection does no more work via dragging your mouse or using shift+arrows.There is already a fix but STM32CubeIDE does not provide the fix as update as of now.I already filed a case. 

In the "Debug Configurations" window (or at least that is the only place I have verified it so far), when scrolling down to access the options at the bottom, the mouse pointer might accidentally hover over a combo box. If you continue scrolling, the combo box cycles through its options down to the last value before the main window continues to scroll.This can cause (and has caused me) quite a few headaches while debugging one of my projects.I believe the correct approach would be to disable this scrolling behavior for combo boxes to prevent accidental changes.Best regards!

hello ST Community!I'm trying to connect via UART without USB ST-LINK to the NUCLEO-H755ZI-Q for debugging from the STM32CubeIDE environment, but I can't connect.What settings do I need to make in the STM32CubeIDE environment to debug via UART?I tried connecting via UART from the STM32CubeProgrammer environment to simply read flash memory, but it won't connect.What settings do I need to make in the STM32CubeIDE environment to debug via UART without USB ST_LINK? Thanks for supports

Hi there,I'm debugging an STM32L081 project with an ST-LINK/V2 ISOL, and the Live Expressions data during the debug session is corrupted.Sometimes, removing all expressions, stopping the debug session, and/or power-cycling the processor makes the data display correctly again. However, after a simple code update, or adding  new data on Live expressions; the data becomes corrupted once more.This has been a known issue since 2023. I’ve seen many colleagues reporting the same problem. Even ST technicians have escalated it under internal ticket IDs 222326 and 175214.Unfortunately, as of early 2026, there has been no update.I have installed the latest STM32CubeIDE 2.0.0, but the issue still persists. Come on, ST team!!!!You are aware of this issue. Please inform the community about when it will be fixed. Thanks in advance.

The STM32 toolchain based on gcc 13.3 already supports a lot of C23 features, e.g. constexpr. This is really awesome.But the current version of CubeIDE seems not to be able yet to parse these new features, so syntax checking / highlighting / code linking breaks.Is there any simple workaround for this? Or is there information available, whether the next version of CubeIDE will update this?

Hey all, just installed STM32CubeIDE on cachyOS and connected my HiLetGo STM32F103C8T6 dev board (https://www.amazon.com/dp/B07VKSVM21), and the IDE is giving me the following error when I try to debug or deploy:I tried installing ST-LINK-SERVER separately just to be safe, and it said that it was already installed. (I assume as part of the Cube IDE installation.) Also reinstalled libusb (Version 1.0.29-1.1).I can see STM32x_USB under Removable Devices in the system browser when plugged in, so I know the board is connecting at least. Any ideas here?

Hi,I am trying to debug STM32N6 program loaded in external flash. When I started the debugger in the FSBL project I can put a breakpoint just before it jumps into application inside external flash. It is obvious I wont be able to see the symbols since it is not loaded. So I loaded my application elf file under debug_configuration/Startup/Load Image and Symbols (See attached image). When I start my debugging session, I encounter the following error and was unable to debug even FSBL code.Board: STM32N6 DKSTM32CubeIDE: 1.17.0Platform: Windowproject: Template_XIP_FSBL (found under Stcube package for N6).Here is the error:STMicroelectronics ST-LINK GDB server.

Split from STM32CubeIDE missing “STM32 Project” and CubeMX after fresh installation - that issue was resolved.This is a new issue.The new version 2.1.1 appears pretty useless even after trying to make a project with the separate cubemx. From the IDE you cannot then build the project. It just sits there. I would hope that the IDE is at at capable of building and compiling the project but it appears that is no longer the case.Did you employ someone from microsoft to break it. It was working perfectly before hand. New->STM Project->.....->build->debug. I will revert back to 1.19 to avoid wasting more time and just use an older CubeMX as that was the only reason I upgraded Please leave working software alone or simply improve it and not break it for no reason

I am trying to download the windows version of the IDE but I can't get it to work. Either the download button doesn't do anything or it's just not there. I've tried with different email accounts, different web browsers, different networks but that didn't do it. I've looked on here and it was suggested to disable browser extensions like ad-blockers and such and I've disabled all of them and still nothing. I would appreciate any help.

I am having debugging issues with STM32CubeIDE. the processor is STM32F030F4Px and I am using a knock off ST-Link V2. It seem that no matter what I configure I get the same error. There also is a check GDB server version error in the IDE window.

Hi C++ Developers,   As you may know, developers downliading Cube tools from st.com will receive an e-mail asking them to provide feedback. From this feedback we see some complaints vs the C++ support in STM32CubeIDE. The complaints are however lacking details. We are aware of several C++ topics which could be improved. But without detail, it is hard to tell what is seen as the highest priority... Here is where we need your help!   Brainstorming on the main C++ issues in STM32CubeIDE (and Cube ecosystem) I arrive at this list of issues::   CubeMX issue: CubeMX does not generate a main.cpp, I have repeatedly seen beginner struggle to create their main.cpp and make calls to C code...   HAL issue: Nor do we offer C++ based HAL drivers or any other middleware.   CubeIDE editor: The Eclipse/CDT indexer providing auto-complete and other editor features in Eclipse was largely sponsored by Intel. There is much less up-stream activity on C++ support

I do not know what happened. If I double-click ioc file, it used to open inside CubeIDE. But now it will open inside another separated cubemx window. I may have changed some settings by mistake.How to change the settings back so I can open ioc file inside CubeIDE?

Where can I find the Option in the Preferences  to set the text of the function Name to “Bold”?

Hello guys, I started a project using STM32C552RET6 and STM32CubeIDE. When I use the autocomplete feature to select a HAL function, I can’t find it. I have to type the function manually.Does anyone know how I can fix this problem?Thanks for your help.

Hi SupportI have experience in STM32 with Zephyr but I am trying out AMP for the first time.So I am trying out OpenAMP example from STM32CubeIDE. I can compile the example but cannot flash the same.I have the following errorThe ST-Link device is present as shown below I have tried other boards like NUCLEO-G431RE with some simple UART example and work well.I have problems only with AMP board, I am not able to flash M4 and M7 core. My dev environmentUbuntu 22.04 and STM32CubeIDE ver1.1.8.1 Could anyone please help me understand the same?  

Subject: Performance difference between GCC (-O2) and Keil ARM Compiler in motor control applicationDescription:I am currently developing a motor control application using STM32F303 and comparing the performance of two development environments: STM32CubeIDE (GCC ARM toolchain) and Keil µVision (ARM Compiler).Hardware & Software Environment:MCU: STM32F303STM32CubeIDE Version:2.1.1Keil MDK Version: v5Motor Control SDK Version: X-CUBE-MCSDK v6.4.2Optimization Level: -O2 for both compilersFOC Algorithm: [hall FOC]PWM Frequency: [16 kHz]Test Methodology:I have ported the exact same motor control source code to both environments. Performance is measured by:I noticed that the .hex file generated by Keil （100 KB） is smaller than the one generated by STM32CubeIDE （103 KB）. Does this come from the compiler difference?Has anyone performed similar benchmarks between GCC and ARM Compiler for motor control and found strategies to close the gap?

I encountered a strange problem while using STM32CubeIDE. After clicking "Debug" and then "Exit," in all subsequent actions (unless I restart the software), when I click "Download" (not "Debug"), the IDE interface redirects to another file (the line `ldr sp, =_estack /* set stack pointer */` in `startup_stm32f407vgtx.s`). While it's not a major issue, it's certainly annoying, like having sand in your shoe. I'm seeking a solution.

I have started a CMake project with CubeMX. I can edit, build and debug using VS Code. CubeIDE has some debugging abilities missing in VSCode extension. So I would like to know if there is a way to do all the extensive editing in VSCode and the debugging in the IDE. That would be an ideal scenario because I could combine the best features of both environments.

I'm building a (relatively simple) application with STM32C011F6J6 using HAL for managing onboard peripherals. I believe moving some of the I/O code to LL or "bare metal" (direct register manipulation) would help reduce flash demand - 32K byte budget - but would like target these efforts.Is there a way (perhaps using the linker that's part of STM32CubemX) to get a memory map telling me how much flash is occupied by each function call?Thank you 

I am working with the NUCLEO-U575ZI-Q and I am implementing the ADC GPDMA examples described in this STM32U5 workshop https://community.st.com/t5/stm32-online-courses/stm32u5-workshop/ba-p/774159. Within the project, a GPDMA channel is configured to collect 4 channels of ADC data triggered by a timer in a buffer called data, use 2D addressing to rearrange the channel data in a new buffer called dataGrouped, then transmit the data over UART. The first time I built the project and ran the debugger in STM32CubeIDE, I was able to add the two data buffers being used by the DMA channel to the live expressions view and monitor the data in real time to confirm that the DMA channel is functioning properly. However, after terminating the debugger and relaunching it, even without making any changes to the firmware, the expressions I added no longer update and just display 0. The same expressions are still displayed properly in the Expressions tab once I halt execution. The only way I ha

The configuration for include paths in cubeIDE seems horrendous.  I have installed CMSIS 5.9 using MX no problems.  IDE didnt pick it up. Manually configured the path into cubeIDE..... still cant see the include file ... even though it is right there.I am using exist source files imported into cubeIDE but there is no easy way to make the cubeIDE see the include paths.Bang head .. repeat.Do I have to manually copy the CMSIS DSP files into the project ??I see from the web this problem occurs alot .. with many different "solutions".    

SirWe are not able to program the stm32h725vgt6 board.We got some issues and in order to rectify the issue  we have connected  VDDSMPS and VFBSMPS to the GND and voltage on the VCAP ia about 1V for supply 3.3V V.

I am new to STM32CubeIDE  2.0.0 environment and I cannot debug my first project. See failure message in attachment.  What do I need to do to debug in this environment?  Is there instructions hidden somewhere that I need to follow?
