STM32 MCUs Software development tools

Hello,I am using STM32H750ZB variant for an HMI custom project and I am using SDRAM via FMC.When I configure FMC in cubeide1.19.0, I can't see the FMC_NBL0 and FMC_NBL1.I can actually add these pins as GPIOs, but I can't define the AF as AF12_FMC.I know from the datasheet that this package supports it but I want your confirmation as I still don't have HW to test and don't want to change the package again and redo the HW.Thanks,Ayoub  

Hi all,What is the recommended way to not crush our repository and dynamically pull/generate the project's Drivers and Middleware folders?  For instance, our repository has both Bootloader + Application code projects in a repo (and other MCU projects/layouts for the same board).Is there something similar to Platform.IO (or C#'s NuGet packages) where the platform maintains those 3rd-party files in a volatile location and pulls them if they don't exist on your machine? Especially for the sake of not checking into the repo duplication of +15 MB worth of files for each project.Please excuse me if this was already asked. I didn't quite find a solid answer.I'm ok with making a command line script that auto-pulls them too, if that's a possibility.

As i updated my STM32CubeIDE to the latest site version available, i am getting new errors in my working code.Those errors before update were displayed as warnings but after update they are turning into errors. passing argument 2 of 'xfunc' from incompatible pointer type [-Wincompatible-pointer-types]My -Werror is unchecked from the start.If someone can help me how to resolve it, Thanks in advance.

I'm using a STM32F407VG (actually a disc-1 board). I've set I2S2 in full-duplex master mode and generating the MCLK out on PC6 for an external slave codec. So far so good.Now i want to set SDIO interface in full-duplex 4-bits mode but CubeMX throws a warning about a partial conflict with I2S master clock out. Frankly i have no clue about it, can i safely ignore the warning? 

To sum up my project, i get temperature value from NTC. I made ADC reading. There is no problem about getting values. I define temperature value as floating point variable. When observing it on debug screen, because it was floating, numbers after . is too much like seven digit. As you see in picture, is there any way to reduce the number of digits on debug window? temperatureDisplay 

Recently, I bought a clone of ST-Link V2.I am trying to program a RAK5205 board with an STM32L151CB MCU on it, with a basic program for blinking LEDs.If I use the STM32 ST-Link Utility v 4.5.0.0, open the file RAK5205_Blink.hex and program the MCU, it ends correctly and the program runs without problems on the board. If I want to completely erase the Flash memory, it does it correctly with this indication:Device ID: 0x429Device flash Size: 128KBytesDevice family: STM32L100x8xxA / L15xx8xxAFlash memory erased.Now, if I open the STM32CubeProgrammer v2.1.0, open the same file RAK5205_Blink.hex, the ST-Link v2 is recognized and connected correctly, read the memory of the MCU without problems, but when I want to program it in the same way than before, it shows the error, "Flash loader can not be loaded".What is the difference between the ST-Link Utility and the STM32CubeProgrammer regarding device detection and programming? What exactly does the error"Flash loader can not be

I am not able to find the built in drivers, which comes by default, when you download the software. This is not allowing me to get the whole main.c file to perform the projects. Can anyone help

I created a motion_fx for stm32h562 from CubeMx. The auto generated motion_fx.h file does call (line 135)size_t MotionFX_GetStateSize(void);​But the code does miss the include #include <stddef.h>Which results in the following error:unknown type name 'size_t' motion_fx.h ./Middlewares/ST/STM32_MotionFX_Library/Inc line 135 C/C++ Problem 

Hi,In STM32CubeIDE/MX versions 1.19 and 6.15, I configured HRTIM, and it worked fine without any errors in CubeMX. I have updated STM32CubeIDE/MX to versions 2.1.1 and 6.16.1, and I have noticed the error messages shown in the pictures below.The dead time is not used, but when set Output 2 state MX displays the message "Set Sources: nothing to set as Dead Time is enabled, Output2 signal is defined based on Output1 Configuration Set Sources". The project operates like before the update, but it is not possible to add new Set Sources (I can only change the number of Set Sources to zero). How to understand this behaviour?Krzysztof  

When connecting to our stm32n6 using a stm32 Programmer we get an unstable connection. Connecting with a low clock rate (5khz instead of 8000khz) improved the Issue but there still isn't a reliable way to connect to the board. Some retries are needed to get a connection. Also after some time the connection doesnt work entierly and the MCU needs to be powercycled.  

Hi, I'm using the STM32U5G9J-DK1 Demo Board with the STM Demo Program Ux_Device_DFU, because I need to create a specific bootloader for my board.The STM32CubeProgrammer program connects to the board via USB and I can read its memory, but the program doesn't receive information from the Flash Blocks, so programming doesn't start.If I enable the Bootloader available in the MPU's system memory, the programming via the STM32CubeProgrammer works correctly.What should I change in the STM source code to avoid this problem?Thank you in advanced

In a recent release (not sure which one) the option to select USER_PHY was added to the platform settings under LWIP.I need to implement a different PHY for a LAN9374. It is basically identical to the LAN8742. The only issue is that the LAN8742 init code fails unless modified slightly. If I select LAN8742 and modify the file I can get it working but as expected every time I regenerate the project the modifications get overwritten. Where is the documentation on how to implement a USER_PHY?

Hi everyone, I’ve been working on an STM32 project using STM32CubeIDE on Windows 10 (i7-9700K, 16GB RAM), and I’m running into a frustrating issue. Every time I start a debug session on my Nucleo-F446RE board, the IDE sometimes freezes or crashes after hitting a breakpoint. I’ve tried updating CubeIDE to the latest version and reinstalling the ST-Link drivers, but it’s still happening intermittently.One thing I did notice is that my system isn’t always completely clean in the background. I sometimes run lightweight games during breaks, like Stick War Legacy, and recently I tried a mod APK version from stickwarmods. I’m not sure if something from that could be affecting system stability or leaving background processes running, but I thought it might be worth mentioning in case it’s related.Has anyone faced similar issues, or is there a recommended way to debug without the IDE crashing? Any tips would be really appreciated!

Hello, Long time lurker here. First of all, thank you for the extensions, really appreciated the possibility to work directly in vscode.I have a couple of situation, however, that are really annoying and that I would like to solve. While developing in vscode with the extension enabled. It is sufficient to update the CMake presets in order to have the tools installed by the ST extension to make the git repository dirty.If before committing the files to the repo a pre-commit that formats the files in a proper way then it is amplificated.The files: c_cpp_properties.json in the .vscode folder is always updated with the compileCommands updated if dynamic folders for Debug and Release are used .clangd configuration file is updated in the CompilationDatabase field.In my opinion there are two different types of settings: settings that needs to be persinstent, and maybe reusable on different computers by different userssettings related only to the current runThere

Hi, I consistently hit HardFault when using PICOLIBC. I am using a STM32H735G-DK board.Setup:1. Start from a black CubeMX project, selecting the board and default pins. The FreeRTOS must be enabled, and the TouchGFX (with the MPU configured). We will target CMake and SR Arm Clang. Generate code.2. Open TouchGFX and load the project with the file ApplicationTemplate.touchgfx.part. No need to add anything, just generate code.3. Open the entire project with VSCode. The project by default uses the PICOLIBC in the file starm-clang.cmake. The project as is compiles successfully. flash onto the board and click Continue. The code will instantly go in HardFault_Handler().Here is a printscreen: Can anyone try to reproduce this, just to make sure it is not something only on my side? Thank you!If I change for STARM_NEWLIB in starm-clang.cmake instead of STARM_PICOLIBC, everything works as expected, no hardfault, and the screen initializes successfully.I have added a demo project.

Disclaimer:Probably not quite the right place for this bug report. However, since the issue appeared with the update to CubeIDE VSCode v3.8.0 and STM32CubeMX v6.17.0, and the project in the attached ZIP was created with these versions to reproduce the behavior, I am placing it here.IntroductionLink to Project on GitHub: init_array_issue (or use the attached ZIP file)The code in file init_array_issue.cpp demonstrates a misbehavior where, under certain conditions, the initialization of objects is silently skipped without any warning or error message when picolibc is used together with the linker description file STM32H753XX_FLASH.ld generated by STM32CubeMX and the default optimization -Og.picolibc / STARM_PICOLIBCThe use of picolibc has been the default since the STM32CubeMX update to 6.17.0, configured via the option STARM_PICOLIBC in the file .\cmake\starm-clang.cmake.Previously, STARM_HYBRID was set here by default.# STARM_TOOLCHAIN_CONFIG

Could I erase rtc backup registers with STM32CubeProgrammer ?

Hello,I just downloaded STMCubeIDE 2.1.1 to generate a simple project for a Nucleo-C562RE board.I am not using CubeMX2 (for various reason, that is not the point).The default empty project generated for STM32C562RE by the IDE has only 1 SRAM element with a size of 64K, instead of 2 SRAM elements of 64K each.FLASH size is correct though.Out of curiosity, if ST were to push a fix for this kind of bug, would it be a new IDE release ? or could it be a STM32C5 pack update only ?

When i try to add breakpoint, there is a cross sign on breakpoint symbol. So even if the code works, breakpoint never works.I try to add __asm("BKPT 0"); but it also did not work. I am not sure what is the problem.My CubeID version is: Version: 2.1.1Build: 28236_20260312_0043 (UTC)

Hello,Before compilation:   I’m having an issue with IntelliSense (possibly clangd).When a macro is undefined, the code inside #ifdef is correctly shown as inactive (dimmed). However, after I build and flash the project, the same code becomes highlighted as if it were active, even though the macro mDEBUG is still not defined.The highlighting only returns to the correct state after I switch tabs or force a refresh.Is this expected behavior, or could this be a bug or bad config on my side? It brings confusion to my workflow.After compilation:
