STM32CubeIDE (MCUs)

Hello, I am using a firmware package with the System Workbench for STM32 IDE and would like to ask how I can configure a peripheral and integrate it into my code. Additionally, does it support code generation similar to STM32CubeMX? Thank you in advance!      

Hello,I am converting from Arduino to STM 32 Cube IDE. Here I have a Problem with include paths:What I want:- Develop Libraries in a special folder- Add the libraries as a LINK to the Cube IDE- use #include command to include the library into the project What I have done:- I made a new Project "Blinky" in the cube IDE - done- I selected a nucleo board in the cube IDE - done- I programmed a hello world blinky using HAL without libraries - done.So the environment and the board is running.- right clicking on the project  I created a new source folder "MyLibs"By drag and drop I copied my library called "After" folder into the new MyLibs folder. Answered the message by "copy link only" into the new folder "MyLibs"The copied folder "After" contains an other folder "src" where the source files are located. Here a picture of the project: 

I have five projects on the go, which compile and debug well on STM32CubeIDE 1.X.X (at least for 1.12.0+), but with warnings. I am now trying to shift to more recent versions of CubeIDE (2.X.X), but they behave as if ">Properties>C/C++Build>Settings>Tool Settings>MCU>MPU GCC Compiler>Warnings>Treat warnings as errors (-Werror)" is enabled, even when it is not.I believe that my settings in the more recent CubeIDE are identical to the older one, and I have tested this on two different computers with similar results. The error which is currently causing the compilation to halt is " ...error: implicit declaration of function 'xxxxx' [Wimplicit-function-declaration]", but if I resolve it, another item which should be a (legitimate) 'warning' will appear as an 'error'. I am using "ISO C11 (-std=c11)", and have the same issue if I attempt to use GNU11.Unfortunately, I cannot resolve all the warnings without creating other problems, so this issue i

hello team, I am facing a debug connection issue with STM32H723VGTx using STM32CubeIDE and ST-LINK.Issue details:MCU: STM32H723VGTxDebug tool: ST-LINK (OpenOCD via STM32CubeIDE)Interface: SWDReset mode: Software resetSWD frequency: 50 kHzObserved behavior:ST-LINK connects successfully.Cortex-M7 core is detected correctly.GDB server starts, but the debug session fails during memory access.Error message: Error: Failed to read memory at 0x5c001000 Error: auto_probe failed Error: Connect failedAdditional observations:

hello ST Community,where can I set it to avoid generating the file "startup_stm32l5...zetxq.s" during compilation and debugging in the stm32CubeIDE environment and also how to avoid that the space bar "|" when editing the line of code of 'main.c' is automatically moved to the last line of code of 'main.c' during compilation and debugging. Where should I set it to avoid all this?Thanks so much for your support

I have recently installed STM32CubeIDE 2.1.1 on linux and opened an existing project workspace. Everything looks fine except the integration with CubeMX for ioc files (which I believe is now by-design). The problem I have is after going to eclipse marketplace and installing Subclipse, it installs fine, then after restarting it goes into an endless loop saying the application is not responding. Finally, I got a message about "Failed to load JavaHL Library.", but I'm not sure if that's the real cause as dismissing the dialog reverts back to the application not responding loop.  Reinstalling the IDE does not help. The only way I've found to get the IDE to work is by removing the stm32 folder under $HOME/.eclipse, but this doesn't correct the issue with subclipse or its connection to subversion. Any help much appreciated.

STM32CubeIDE 1.14.1I have imported a CubeMX generated makefile project.  When I enter the debug configuration dialog, I get an error "Unsupported build configuration. MCU ARM GCC required for debug." I have not found any documentation from ST indicating how to install this.  I am also curious why a dependency required to debug an ST MCU does not come with ST's Eclipse debugger. The Eclipse Marketplace returns an error 500 when I search for MCU ARM GCC.The Install New Software dialog just spins forever, not even loading any package data. What I'm looking to do:Debug an MCU application on my target board.I do not actually care about STM32CubeIDE, I am fine using stock Eclipse.  But I do need documentation on how to set up the actual ST specific debug tooling, and this information either doesn't exist or is difficult to find.  If ST's IDE works, that's fine too, I don't really care.

Added dual-core to title - may be significant ...Hello.I've tried rename my project in the past, and this always generate a lot of errors due to the dependencies.Which is the properly way?I am working with STM32H755. Yes, dual-core.Thanks!

Title edited to indicate that this is specific to J-Link.Hi,After updating to STM32CubeIDE 2.1.0 I get the following message after starting a debug session. Live expressions do not work.From the console:SEGGER J-Link GDB Server V9.14a Command Line Version JLinkARM.dll V9.14a (DLL compiled Jan 28 2026 17:11:52) Command line: -port 2331 -s -device STM32F769NI -endian little -speed 4000 -if swd -swoport 2332 -vd -rtos C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.external

HiAs I experienced some problems with 2.1.0, I reverted to 2.0.0 and in that process I seem to have gotten the error:Program "gcc" not found in PATH - "[Discovery options] page in project properties"I followed the instructions found in the stm32CubeIDE user guide https://www.st.com/resource/en/user_manual/um2609-stm32cubeide-user-guide-stmicroelectronics.pdf, but the problem persists.Is there a way to manually clear this from any of the configuration XMLs perhaps?The code does still compile and creates binaries, so the error is just a nuisance.[Edit] spellingBest regardsMartin

I am facing an issue in STM32CubeIDE on Windows where the I/O Configuration / Pinout & Configuration window is not appearing after creating or opening a project.Normally, when opening the .ioc file, the Device Configuration Tool (CubeMX interface) should open showing the MCU pin diagram and peripheral configuration options. However, in my case, this interface is not appearing.Issue Details:Operating System: WindowsSoftware: STM32CubeIDEWhen I create or open an STM32 project, the Pinout & Configuration view does not open.The .ioc file either does not open correc

Hi,When I worked on the Discovery kit with STM32F769NI MCU it supported in the STM32CubeIDE/MX the  LWIP package (from 2025) with FreeRTOS/V1. Now when I pass my project to NUCLEO-H563ZI I see in the TM32CubeIDE/MX that ST will not support the LWIP with FreeRTOS anymore. FreeRTOS is only v2 in this board.Is someone integrete the LWIP package on NUCLEO-H563ZI with FreeRTOS/v2? The code main files that should be changed from STM32F769NI to NUCLEO-H563ZI  are LWIP/App/lwip.c, LWIP/Target/ethernetif.c/h, LWIP/Target/lwipopts.h, main.c.Is there any project in git that have done this miggration for LWIP package (code from 2025) and using FreeRTOS/v2 in it's LWIP package? Or share with me those 4 LWIP files for NUCLEO-H563ZI board. Thanks.

Hi I have created a project using STM32Cube.AI Studio. I am able to successfully run and generate the project from the tool. After that, I can open the project in STM32CubeIDE and build it without any issues.However, while debugging, I encounter the error shown in the image below.I am able to debug the image classification and face detection sample projects provided by ST without any issues. Therefore, I suspect that there may be a problem with the project configuration generated by STM32Cube.AI Studio.The evaluation board I am currently using is the STM32N6570-DK.Please help me to resolve this issue?

I am experiencing a problem with RTOS Proxy in STM32CubeIDE 2.0.0/2.1.0 when debugging a ThreadX application on STM32H753 using a SEGGER J-Link.The same setup works correctly with STM32CubeIDE 1.19.0, but after upgrading to 2.0.0/2.1.0 the debugger aborts during the flash download when RTOS Proxy is enabled. If I use J-Link Kernel Awareness instead RTOS Proxy everything works fine.ConfigurationMCU: STM32H753BIRTOS: ThreadXSTM32CubeIDE: 2.0.0RTOS Proxy: ThreadX / Cortex-M7Debug probe: SEGGER J-Link Ultra+J-Link GDB Server: V8.80Interface: SWDDebug configuration:RTOS Awareness: EnabledRTOS Kernel Awareness: RTOS ProxyRTOS: ThreadX (Cortex-M7)

 Hi everyone,I am experiencing issues with Task Aware Debugging (FreeRTOS Task List) in the latest version of STM32CubeIDE. The "FreeRTOS Task List" view is either empty or not populating correctly, despite the scheduler running and tasks executing effectively on the hardware.Environment:IDE: STM32CubeIDE (Latest Version)MCU: STM32H7S3L8H6xFreeRTOS Version: V10.6.2 (CMSIS-RTOS V2 wrapper)STM32Cube 2.0.0Interestingly enough, the runtimestats itsef are working.Does anyone have similar issues? 

Dear STM32CubeIDE Support Team,while analyzing the memory usage of my STM32 project, I noticed a potential inconsistency in how memory units are displayed in STM32CubeIDE.Both the Build Analyzer and the memory overview label the values as “KB”, but the reported numbers clearly correspond to KiB (1024 bytes) rather than kB (1000 bytes). This behavior matches the output of arm-none-eabi-size, which reports sizes in bytes.For example:arm-none-eabi-size reports Flash usage as:text + data = 64824 + 148 = 64972 bytesConverted to kB (1000 bytes), this would be:64.972 kBHowever, STM32CubeIDE displays:64972 / 1024 = 63.45 KiB, while labeling the unit as “KB”As a result, summing RAM and Flash values only produces consistent re

Hi, I want to know when the C/C++ Indexer will be updated to the latest C standard, that is, C23? I want to use some new language features, like double square brackets for attributes, but it still shows a syntax error, even though the code compiles without problems.Also, I would like to know when GCC 15 will be available. Best regards,Artur 

I've just installed the new STM32CubeIDE 2.1.0 and I came across some issues that didn't exist in previous versions.First, I noticed that the compiler always compiles all the source files even though only one source file was modified. I have large project with many source files and it takes about 2 minutes to compile all files. It's very annoying.Second, when launchinig debug session all the source files are compiled again. It didn't work that way in previous versions of STM32CubeIDE. If the files were compiled previously, the debug session was launched immediately.Is it possible to change this behavior but turning off some options or do I have to install older version of STM32CubeIDE ? 

A few days ago I updated STM32CubeIDE from version 2.0.0 to 2.1.0. (Build: 27993_20260219_1630 (UTC))Now there is a problem. There seems to be no longer any such thing as a "partial" build. Example: My project consists of about 50 ".c" and ".h" files. In the old version, if I edited one of the ".c" files and did a build, only the file that was edited got re-compiled, followed by (as expected) linker and hex file generator. Now, in this version, every build re-compiles ALL the files, even if nothing was touched since the last build. This is time-consuming. How can I stop this and get it to re-compile only the changed files? (If it matters, target CPU is STM32H753BIT6; using FreeRTOS and FATFS.)

Cube IDEIf i create / Import STM32 ProjectI only got these options to pick from and i have the feeling something is missing.  So i select:- STM32CubeIDE Empty Project which leads me to this:So i select my MCU: STM32G474RETx (for example).This leads me to this:

Hi,among probably many other registers, the ITM registers like TCR and Stimulus Port Registers described in the ITM programmers model in ARM Cortex-M7 Processor TRM are missing. Which means I either have to adapt the svd file or go to memory view and translate and modify the registers manually. Is this on purpose and or are there plans to fix this? If you have a repository somewhere I can maybe fix that on my own and start PR.Ty in advance

Is it ok to use different build configuations for different pinout version?As you may have experienced, sometimes pcb version how the pinout. Sometimes another UART or TIMER is used in another pin etc,... Is it ok to  use different build configuations for different pinout version?

It seems that after I updated MacOS to Tahoe 26.2 the IDE does not show selected text if over multiples lines correctly. This is a nightmare to work with, as it does not show selected text and can make you delete (overwrite) lines while editing.Anyone else? Is there a setting to fix it?

Hi Team,I’m prototyping on a Nucleo-F303RE using STM32CubeIDE. In the clock configuration, I set the system clock to 36 MHz from HSI (HSI → PLL with the /2 divider), as shown in the clock tree screenshot. However, my firmware misbehaved. After debugging, I found that SystemClock_Config() function isn’t applying the HSI/2 divider when feeding the PLL. Instead of: RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;CubeIDE generates:
