When configuring the LEDs for the STM32H573I-DK using the STM32CubeMX it generated code which initializes the LED pins as PushPull (rather than OpenDrain).Lookign at the schematics of the STM32H573I-DK it seems to be not "the best option".Would you agree that OpenDrain (GPIO_MODE_OUTPUT_OD) is the better option here, rather than PushPull (GPIO_MODE_OUTPUT_PP)? /** * @brief Configures LED on GPIO. * @PAram Led LED to be configured. * This parameter can be one of the following values: * @arg LED1 * @arg LED2 * @arg LED3 * @arg LED4 * @retval BSP status */ int32_t BSP_LED_Init(Led_TypeDef Led) { int32_t ret = BSP_ERROR_NONE; GPIO_InitTypeDef gpio_init_structure; if ((Led != LED1) && (Led != LED2) && (Led != LED3) && (Led != LED4)) { ret = BSP_ERROR_WRONG_PARAM; } else { switch (Led) { case LED2: /* Enable the LED2 GPIO clock */ LED2_GPIO_CLK_ENABLE(); break; case LED3: /* Enable the LED3 GPIO clock */ LED3_GPIO_CLK_ENABLE()

I'm running Bazzite (Fedora 43) and tried to install STM32CubeMX on a Fedora distrobox and was met with some issues.First, the installer is unable use /bin/chmod, this is fixed by switching out the installer's `jre\bin` directory for OpenJDK.Second, if you run as a normal user it fails with:com.izforge.izpack.api.exception.IzPackException: An error occured in java.lang.Thread.run() at Thread.java:1583 in com.izforge.izpack.installer.unpacker.UnpackerBase.run() at UnpackerBase.java:241 in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:319 Caused by: com.izforge.izpack.api.exception.InstallerException: File execution failed in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:299 in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:483 in com.izforge.izpack.installer.unpacker.UnpackerBase.executeFiles() at UnpackerBase.java:959This is fixed by running the installer via sudo.This is what I did

I have an old Ubuntu 18.04 system which allows STM32CubeIDE to run, but the STM32_Programmer failed because libm.so and libc.so were wrong. I found glibc-2.30 and copied the libraries into the same directory as the STM32_Programmer lib. Now I just get a seg fault, even when trying to just get the version number:bin/STM32_Programmer_CLI --version Segmentation fault (core dumped)Is there any way to figure out what might be the problem?   

Hallo zusammen,mir ist im STM32CubeProgrammer (GUI, v2.19.0) ein merkwürdiges Verhalten im Automatic Mode aufgefallen:Wenn man den Haken bei "Run after programming" direkt aktiviert und dann auf „Start“ klickt, wird kein Reset ausgeführt, obwohl die Option gesetzt ist. Das Programm wird nicht neu gestartet. Wenn man schnell hintereinander viele Platinen updaten will mit Neustart des Programms ist dies hinderlichWorkaround:Wenn man den Haken einmal entfernt und dann wieder setzt, funktioniert der Reset im Automatic Mode anschließend wie erwartet. Offenbar wird die Option intern erst korrekt übernommen, wenn sie aktiv verändert wurde.Das Verhalten ist reproduzierbar und tritt unabhängig vom Ziel-MCU auf (getestet mit STM32L4 und ST-Link v3MINIE).:wrench:Vorschlag:Es wäre super, wenn das in einer der nächsten Versionen behoben werden könnte – vermutlich reicht ein Fix im Initialisierungsverhalten der GUI.Viele GrüßeBB-RTB Translation:Hello everyone,I noticed some strange behavior in

I have been programming my STM32H743 custom board for over a year.  Suddenly I'm getting the error message Error: No STM32 target found... I have tried changing the ST-Link itself but get the same error message.

Hello,I just created a new project for the STM32L542CEU MCU with CubeMX and I'm facing two issues with the imported project in CubeIDE.First issue, rather easy to fix, some path for includes files are missing in the project.Second issue, two include files are missing:Description Resource Path Location Typefatal error: ARMCM0.h: No such file or directory RTE_Components.h /CURRENT_SENSING/Drivers/CMSIS/NN/NN_Lib_Tests/nn_test/RTE/_ARMCM0 line 17 C/C++ Problemfatal error: irq_ctrl.h: No such file or directory os_tick_gtim.c /CURRENT_SENSING/Drivers/CMSIS/RTOS2/Source line 26 C/C++ Problemmake: *** [Drivers/CMSIS/RTOS2/Source/subdir.mk:25: Drivers/CMSIS/RTOS2/Source/os_systick.o] Error 1 CURRENT_SENSING C/C++ Problemmake: *** [Drivers/CMSIS/RTOS2/Source/subdir.mk:25: Drivers/CMSIS/RTOS2/Source/os_tick_gtim.o] Error 1 CURRENT_SENSING C/C++ Problemmake: *** [Drivers/CMSIS/RTOS2/Source/subdir.mk:25: Drivers/CMSIS/RTOS2/Source/os_tick_ptim.o] Error 1 CURRENT_SENSING C/C++ Problemmake: *** Wait

I have an stm32 board connected to a raspberry pi.I am trying to start a remote debug session from StmCube IDE Installed on my computer and I get this error.I haven't encountered this problem before and I don't quite understand its cause because I have configured everything correctly :- in Cube IDE Debug Configuration I selected connect to remote GDB Server with correct host name and port 3333.- in the pi side I created an openocd.cfg file which includes "bindto 0.0.0.0" command in order to allow connections from any ip.

Hello all, I need to use some FFT functions. I have installed the CMSIS-DSP 1.16.2 and CMSIS 6.3 core as it was required from  CMSIS-DSP. Surprisingly, CubeMX did only a part of its job, namely it did not copy source files and did not add proper include paths to the project so I have to do it myself. But after this there is still a bunch of unresolved references, namely arm_cfft_sR_f32_lenxxx and twiddleCoef_rfft_xxx. I have looked all sources in the CubeMX H7 pack version 1.13.0 I use through but could not find these sources. With best regards,Dmitry 

Hello, Iam working o STM32H573I-DK Board when am trying to access board am getting trustzone issue.I tried with Debug Authentication also but am unable to access board.Find the attached description. 

  I have tried using STM32CubeMX 6.17.0 to generate an STM32F429 DISC1 project.The generated project opened in STM32CubeIDE could not be compiled unless I add <root folder> in Project -> Properties -> C/C++ General -> Path and Symbols, the source location tab.I don't know how this happen. It's disturbing to modify project settings each time after modifying the CubeMX and generating the project.It's probably that should happened after I add some source folders to the projects. 

I am working with STM32N6570-DK. My code is building fine , suddenly a hard fault has started coming. I have tried updating firmware, resetting the board, unplugging and reconnecting it, But debugger is getting stopped after sometime. 

So apparently in 2026, creating a basic embedded C project now requires… a login.Tried spinning up a project in STM32CubeIDE and got a nice “half-built” result:Project created ✔Code generation :cross_mark:Explanation :cross_mark:Turns out the IDE now needs to quietly download the HAL/CMSIS packages, which in turn requires a myST account login… but:It doesn’t tell you thatIt doesn’t prompt you (on Linux at least)It just silently fails and leaves you debugging yourselfSo you end up thinking:“Did I misconfigure the clock? The linker script? The .ioc?”Nope. You just weren’t logged into a website.Nothing says robust embedded tooling like a hidden cloud dependency for generating main.c.Bonus points for the UX where the “login” option is buried under:Help → STM32Cube Updates → Connection to mySTBecause obviously that’s the first place you look when your GPIO project won’t build.Anyway—manual firmware download and local install fixes it. Once you discover the secret handshake.Progress :thumbs_

Hi @Ghofrane GSOURI. I just noticed new STM32CubeMX2. It's for STM32C series currently but I downloaded it to check it out. It looks very nice, that's for sure. Yet this topic is about file format. MX2 re-uses .ioc file extension but it's format is strange. It is made of JSON/Python?? multiline strings containing JSON and YAML. I don't understand what format is it exactly. The data inside it is also hard to understand and there is a lot of clutter, like IDs, URIs, URLs, descriptions, etc. Why on earth would somebody put field description text beside field name and value?If I may express may opinion - this is awful. It's even worse than old format. It won't be easy to merge changes in such file. It looks like it's a mash-up of multiple tools/libraries serialized states. CubeMX developers are going to have backward and forward compatibility problems and end users are going to suffer if bugs emerge.I would like to suggest one more file format: TOMLEdit: Moved from New IOC file f

Hey Team, Another day with a different problem.We have reached the point where we have to migrate to either XIP or LRUN in the life cycle of our project.We choose to do XIP and set up the External memories appropriately , For this workflow, we are using the the stm32N6DK, and  MX66UW1G45G_STM32N6570-DK.stldr for starters.We have set up the debug session as indicated in the  Getting started with STM32N6 MCUs in STM32CubeIDEAttached are theDebug logs from some of the debug sessions.The content of my linker scripts (FSBL) and (APPLI)Screen shoots of debug configurations . Spoiler (Highlight to read)Our debug sessions fail straight from the beginning as shown int the debug logs.Our debug sessions fail straight from the beginning as shown int the debug logs.Note:  At some point the debug session worked okay,Every time it worked I had not to have break points inserted in the application project.I am currently inclined to think the issue is with the IDE debu

I am working with the STM32N6-GettingStarted-ObjectDetection demo.  I found that doing a full chip erase wipes some bootloader code.  I was able to get my project going again by flashing the .hex file that came with the STM32N6-GettingStarted-ObjectDetection demo, the loading my code. Digging around on the net suggested that the prebuilt demo has a bootloader.  I have been unable to locate the bootloader.Can you provide me with the bootloader, preferably as a .hex file?

I began to learn STM MCU programming. I use Arduino framework. Is It possible to get full access by using Vscode + platformIO + Arduino framework. Full access means can functioning all features of stm ic.  I have stm32 blue pill development board. Please give me the guideline to become a professional and perfect stm programmer. 

We have a custom stldr file that we generate to program external flash on our board with STM32U599VJ MCU, we use STM32 CUBE IDE with Jlink. How do I point the IDE to use my stldr file when loading code to onchip and external flash? The option to point to an external loader stldr appears on my if the debug configuration is chosen with STLink, not for Jlink.  ThanksSansh 

I am making use of the SWV to plot a 5Hz Sine Wave.The output on the plotter does not resemble a sine wave:Any recommendations to fix this?

There does not seem to be any way of viewing a debug variable in hex.The closest workaround is to prefix (void*) before the expression in the watch window. This is no good for viewing an array of hex digits like for example a CAN bus message.

Dear all, I have an arm Ubuntu system and would like to use the st32programmer. Unfortunately, ST provide only this code for Intel Linux machine Any chance to have this tool ready for arm Ubuntu machines? Kind regards, Edo  

I upgraded to STM32CubeIDE Version: 2.1.1 and imported my existing projects as STM32. I opened Project / Properties / C/C++ Build and it says "This is not a CDT project." I've never seen that before using version 1.18.1. What happened and how can I fix it?

I am experiencing an issue in STM32CubeMX where all peripheral Configuration panels stay empty, while the Mode panels and System Core → Parameters render correctly.What I have already tried:Starting CubeMX standalone (not via CubeIDE)Creating a completely new empty projectDeleting the .stm32cubemx folderDeleting and rebuilding the entire STM32Cube\RepositoryReinstalling CubeMXForcing JavaFX software rendering (-Dprism.order=sw)Setting Windows display scaling to 100%Enabling/disabling GPU accelerationVerifying that the bundled JRE is complete (java.exe + jvm.dll present)In all cases, every peripheral Configuration section remains empty, while Mode sections work normally.It appears that the JavaFX UI for peripheral configuration does not initialize, but without any error message.Has anyone seen this before, or is there a way to force or debug the JavaFX UI subsystem in CubeMX?Thank you in advance.Kind regards, Cornelis Dekker (Netherlands)

I am using STM32C071FBP6N MCU TSSOP 20 pin package for one of our project.I am observing Pin_20 is muxed with lot of other pins like PB3/PB4/PB5/PB6. if i select PB3 as GPIO_Output using STM32CubeMx and generated a code. If i try to toggle the pin but its not working at all, none of the peripheral on that pin for PB3 is working. But if i select PB6 as GPIO_Output i can able to toggle or modify.This issue is not only with Pin_20, same with Pin_1 also which shares with PB7/PB8, only PB7 is working.I have tried with multiple chips what could be wrong in this scenario??

Hello,The latest version of STM32CubeMX no longer lists x-cube-spn5 as an available package.Could someone help me how to use a X-Nucleo-IHM05A1 expansion board with the latest tools please? 

When I clicked the "Access to MCU Selector" button, the interface did not respond. The pointer just kept rotating to indicate loading. However, when I clicked the "Access to Board Selector" button at this time, the selection interface could be opened.On the board selection interface, when I clicked the MCU/MPU Selector interface, it still showed the situation where the pointer was rotating and indicating a loading process, and I did not enter the MCU selection interface.
