STM32 MCUs Software development tools

I used CubeMX to generate the "LoRaWAN_AT_Slave" example for the B-WL5M-SUBG1 board.I had some issues with it waking up from sleep and upon a few hours of debugging i found that the LSE Driver Config was set to LOW in the example application, but the datasheet recommends HIGH.Just letting other people with the same issue know and hopefully the ST-Team can fix the example configuration in future releases.

On Kubuntu 24.04 when double clicking onSetupSTM32CubeProgrammer-2.19.0.linuxan empty window appears and then closes again. If I runSetupSTM32CubeProgrammer-2.19.0.linuxvia the terminal (as admin or as user), I get this error:Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at sun.awt.X11FontManager.getFileNameFromPlatformName(X11FontManager.java:174) at sun.font.SunFontManager.initCompositeFonts(SunFontManager.java:3506) at sun.font.SunFontManager.access$800(SunFontManager.java:65) at sun.font.SunFontManager$2.run(SunFontManager.java:555) at java.security.AccessController.doPrivileged(Native Method) at sun.font.SunFontManager.<init>(SunFontManager.java:386) at sun.awt.FcFontManager.<init>(FcFontManager.java:35) at sun.awt.X11FontManager.<init>(X11FontManager.java:57) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62

Environment DetailsMicrocontroller: STM32C091CBTx (LQFP48)STM32CubeMX Version: 6.14.1LL-DriverConfiguration: An STM32CubeMX project is configured for an STM32C091CBTx MCU, with DMA channel 6 assigned to a peripheral (ADC).Generated Code (stm32c0xx_it.c): Upon code generation, CubeMX creates the shared interrupt handler for DMA channels 4, 5, 6, and 7 in the stm32c0xx_it.c file. The function is defined as:void DMAMUX1_DMA1_CH4_5_6_7_IRQHandler(void)Startup File Vector Table (startup_stm32c091xx.s): However, the default startup file provided with the project contains an incorrect entry for this interrupt vector. The handler name in the vector table is listed as:DMAMUX_DMA1CH4_5_IRQHandlerConsequently, the `DMAMUX1_DMA1_CH4_5_6_7_IRQHandler` function is never invoked when an attempt is made to trigger DMA Channel 6.Confirmed WorkaroundThe issue can be resolved by manually editing the startup file:In the `startup_stm32c091xx.s` file,Search for the incorre

Hello I found this issue, I drop you my report (with IA helping to write it :) )**Component/Tool:** STM32CubeMX (code generation)**MCU:** STM32C071KBT3 (STM32C0 family)**FW Package:** STM32Cube FW_C0 V1.4.0**Configuration:** USB Device with USBX CDC-ACM class, bare-metal (no RTOS / no ThreadX)**Description:**When generating code for a USB Device project using USBX middleware (CDC-ACM class) in bare-metal mode (without RTOS), STM32CubeMX generates the peripheral initialization calls in `main()` in the wrong order:Generated code (incorrect):MX_USB_PCD_Init(); // Called FIRST MX_USBX_Device_Init(); // Called SECOND**Expected code (correct):**MX_USBX_Device_Init(); MX_USB_PCD_Init(); **Root cause analysis:**`MX_USBX_Device_Init()` calls `ux_system_initialize()` and `ux_device_stack_initialize()` which set up the USBX system memory and device stack. The `MX_USB_PCD_Init()` function's USER CODE section then calls `_ux_dcd_stm32_initialize()` which registers the STM32 DCD driver with the USB

Hi,I have project for STM32F405 created manually. Project is using fixed GCC 4.92014q4.After updating STM32CubeIDE to version 1.14.0 i got warnings shown below.Compiler option "Cyclomatic Complexity" is disabled.File "subdir.mk" contains this rule:# Each subdirectory must supply rules for building sources it contributes Src/%.o Src/%.su Src/%.cyclo: ../Src/%.c Src/subdir.mk How to remove this warnings?

Hi,I just noticed that CubeProgrammer v1.21.0 always shows me an update notification, but it is already the latest.Restarting the Cubeprogrammer or the operating system does not make any difference. Environment:- Windows 11- I have installed v1.21.0 alongside v1.20, but that should not make any difference, or would it? 

The STM32Cube CMake Support extension treats workspaces as STM32Cube projects when a folder higher up in the directory tree (above the workspace folder) contains the files .settings/bundles.store.json and .settings/bundles-lock.store.json.For example, given a tree like this:/ ├── .settings │ ├── bundles.store.json │ └── bundles-lock.store.json │ └── path └── to └── generic_cmake_project ├── CMakeLists.txt ├── generic_cmake_project.code-workspace └── lib.cIf the user opens the workspace generic_cmake_project.code-workspace, the STM32Cube CMake Support extension automatically creates the file .vscode/settings.json with the following content:{ "cmake.cmakePath": "cube-cmake", "cmake.configureArgs": [ "-DCMAKE_COMMAND=cube-cmake" ] }and modifies the generic_cmake_project.code-workspace file by adding the following settings: "settings": { "stm32cube-ide-clangd.path": "cube" },On the other hand, if the user opens the workspace in "folder mode" (File > Open Folder...), the STM3

There's a bug in latest STM32CubeMX v6.16.1. When enabling RAMCFG for Appli on STM32N6 MCU, the IOC file becomes unloadable.I attached the demonstration IOC file. I created new project for STM32N6570-DK board, enabled RAMCFG peripheral for Appli, checked the AXISRAM3-6 areas, defined single continuous area for those SRAMs in MMT and saved the project. After this CubeMX fails to load this IOC file. I get popup:In textual form the error is: Cannot invoke "com.st.microxplorer.mcu.memorymap.MemoryMapService.getInRangeAppRegions(long, long, com.st.microexplorer.mcu.Context)" because "this.mMemoryService" is null.The workaround is to not enable RAMCFG in CubeMX, rather control the peripheral manually.

Since there is no caregory to post for the MCU Finder tool I'm posting here. On Windows, the stand-alone app, as well as the Android app, do not show any content when filtering by the H5 range in the series field. Could this please be fixed? It's been like this for multiple months now. Thanks.

Hello, I am beginner with STM32.I have some radiosonde boards with an STM32L051R6T6. I use STM32CUBE IDE V2.0.0When I start a project, select the appropriate MCU, there is no Core directory and no ".IOC" file.So, it is impossible to access to the GPIOs.I've tried some ways to do that and allways unseccessfull. Please, have you an idea ? NoticeI use also an STM32F103C8T6 board.  I've create my own GPIO lib, my own I2C lib,  and I can compile, flash, debug and run my program. Thank you and sorry for my english  Retired 

Hello,I'm using the STM32N657 on a new project, and its not clear how users are supposed to setup GPIOs that are used in different domains (FSBL, Application, ExtMemLoader).  For example I am using pin PN12 as a LED output and defined it in FSBL.  Why doesn't this definition carry over to the other domains, and how can I get CubeMX to carry it over to the other domains? thanksMatthew   

I've successfully set up a docker container building my project using the headless script. I've also successfully generated a Windows version of the compile_commands.json using the setting inside the properties menu. But I need a version of this that's from the linux build, because I want to lint inside the docker container for continuous integration. I've looked at what gets changed inside the .settings folder when that setting is changed in the normal non headless IDE ("generateCDB=true"), and I've tried simply building the code with that folder and the files in it in the same place in linux, but compile_commands.json is not generated.

I have a project where if I right click on the project in the project explorer, the IDE just hangs. I've tried opening the project in a different workspace, so it's not (I think) a workspace issue. Other workspaces/projects are just fine. Anyone experienced this? Know of a way to fix it? v1.16 on Mageia Linux, using KDE, not using Wayland. Thanks.  

I have setup STM32 VSCode extension on my PC and it is amazing. The only problem that I have encountered is that it is not possible to run the code without debugging. I removed the "runToEntryPoint": "main" line in launch.json. But every time I launch the code it attaches a debugger. How can I simply run the code without debugging? Thank you,Damiano

After several days of wasted time trying to understand what was causing this issue, I finally realized that if I use the add_library() command in a CMake file, the build analyzer tool, without any reasonable explanation, searches for the *.map file with the wrong name. Specifically, if my VSCodeSTM32 project is located in the my_folder directory, then the build analyzer tool looks for the file my_folder/build/Debug/my_folder.map instead of my_folder/build/Debug/project_name.map.I ran into this problem because our project is generated by STM32CubeMX, which uses the add_library() command several times in the cmake/stm32cubemx/CMakeLists.txt file.This is the piece of code that is causing this issue in my main CMakeLists.txt (look in the attached project)################################################################################################################ if(true) # <-- Use false to fix this BUG set(STM32_Drivers_Src ${CMAKE_CURRENT_SOURCE_DIR}/temp.c ) add_library(s

Hello,Does anyone know how to setup the clock source for the N657 processor?  I want to use an oscillator for the HS clock input and setup HSE = Bypass clock source...using Bypass clock it should only use PH0 (clock in) and free up the PH1 pin (clock out).  But it seems the IDE / cubeMx always wants to use both pins regardless of the clock configuration.am I missing something or is this a bug?thanks, Matt  

Hello,I’ve noticed a difference in behavior between STM32CubeMX configurations for STM32H7 and STM32N6 series.On STM32H7, when configuring CAN bit timing, the parameters such as Nominal Time Quantum, Nominal Time for one bit, and Nominal Baud Rate update dynamically based on the settings.On STM32N6 (using STM32CubeMX v6.16.0), these values remain constant. For example, even when using the official STM32 example with a nominal bit rate of 1 Mbit/s, CubeMX still shows a fixed value of 1000 bit/s and does not adjust the timing parameters.My question is:Is this a bug in STM32CubeMX v6.16.0 for STM32N6 series?Or is this a new feature specific to STM32N6 where the tool no longer recalculates these values?I’d appreciate clarification from ST or anyone who has encountered the same behavior.Thanks in advance!

Hi,I want to know what software versions and licenses are part of the STM IDE v1.18.0. For Version v2.1.0 I have found these release Notes which list everything nicelyhttps://www.st.com/resource/en/release_note/rn0114-stm32cubeide-release-v200-stmicroelectronics.pdfOn the STMCubeIDE Download Page / Documentation / Release Notes only lists the most recent Release Note:https://www.st.com/en/development-tools/stm32cubeide.html?ecmp=tt9470_gl_link_feb2019&rt=rn&id=RN0114# How can I find this information for v1.18.0? 

I have an ST32CubeMX project for a STM32H7 mcu generated with STCubeMX 6.4 and using STM32Cube FW_H7 V1.9.1 where the project files are generated via cmake. Now I want to use STM32Cube FW_H7 V1.12.1, but apparently, in order to be able to generate the new files, I have to migrate the project to STM32CubeMX 6.16.1:The problem is that, once I click in "Migrate", it removes two important lines from my code:So, I went to CubeMX to check, and apparently, at a first glance, the field to configure ADC3 Prescaler is gone ( I do not have any other ADC on):Also, the clock configuration tab was showing a problem. I went to check and apparently ADC clock is not allowed to be more than 100 MHz anymore:Unfortunately, I can not slow PLL2P down, since it is used for other peripherals (e.g. SPI), but I could maybe change the clock source to PER_CK and then derive it from HSI to have it as 25 MHz ( 150 MHz + Prescaler of 6 ), although I do not know which other implications it could have.I looked up some

Hello,I was playing around with different versions of MCU and I've notice STM32H7B3LIH has no Graphic Accelerator mentioned in Product Selector.But as soon as I'm selecting it in CubeMX I can enable DMA2D in Multimedia.And think there are more MCUs with Chrome-ART Graphic Accelerator which are not correctly shown in Product Selector.

I'm encountering a persistent issue when setting up an STM32Cube project in VS Code. Even when reverting to a previously working commit or starting a fresh setup from scratch (using the "Setup as an STM32Cube project" button), the process fails.The following error message appears:"Cube project discovery CMake configure step failed. Setup might be incomplete. Please check output logs"I have tested this on two different machines running both Linux and Windows, but the result is the same.
