STM32CubeIDE (MCUs)

Hi,   I have a functioning project that fully compiles with only three warnings, but when I debug it and examine C structures in the live expressions viewer the the data (GovTrimControl_P structure ) appears to be offset by 4 bytes, yet the memory browser shows the correct values and when the mouse hovers over a value that value is correct:       The Build Analyser also reports the address of GovTrimControl_P  correctly Compile Problem Output: The values for the GovTrimControl_P structure are set at bootup to:       /* Parameters (default storage) */ struct P_GovTrimControl_T_ { real32_T FreqSP; /* Variable: FreqSP */ real32_T kD; /* Variable: kD */ real32_T kI; /* Variable: kI */ real32_T kN; /* Variable: kN */ real32_T kP; /* Variable: kP */ }; typedef struct P_GovTrimControl_T_ P_GovTrimControl_T; /* Block parameters (default storage) */ P_GovTrimControl_T GovTrimControl_P = { /* Variable: FreqSP */ 50.0F, /* Variable: kD *

 I was making a project with CUBE IDE and compiling it on the board, and I got this error while compiling the project I was doing on the new board.No source is available for "Call Signal Handler"() in 0xfffffffe.I'm sure they're using the same CPUI can't compile it because it's STM32 ST-LINKI don't think there will be any problems with the code or MX settings because if I modify the code on the existing board, the project will also change well.Even if I create a new project and add the above code, I get the same error, so I can't compile itI want to solve this phenomenon, how do I solve it?  int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MPU Configuration--------------------------------------------------------*/ MPU_Config(); /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE EN

  drag and drop error I have a Mac Pro M4 with Tahoe 26.2 OS, STM32CubeIDE version 2.0.2, and I am having trouble selecting and copying a selection of lines. I tried several tests and that option disappeared. If I am comparing two files, dragging and dropping text works perfectly. Is there any notification about this? Is there a solution?

Hello all,I get an error starting a debug session from STM32CubeIDE (1.18.1) (STM32 Nucleo-F767ZI):STMicroelectronics ST-LINK GDB server. Version 7.10.0Copyright (c) 2025, STMicroelectronics.

Please reconnect the ST-LINK USB cable and try again. If I switch to SEGGER J-Link everythink works fine.Is my debug configuration:What I tried:- Restart PC- Reinstall the USB-Driver (https://www.st.com/en/development-tools/stsw-link009.html)- Erased the flash with STM32CubeProgrammer- Changes USB cable- Googled for solutionsPlease helpBest regards Nikolai   

Problem:I recently updated to 2.0.0 of STM32CubeIDE and I encountered an issue when attempting to build for Debug. I first noticed an issue when trying to run a Debug Configuration. Before 2.0.0, it would build Debug before flashing the built firmware and starting the debugging server; pretty much default settings. Today, it started skipping the build step. I tried building Debug manually with the dropdown on the hammer icon and clicking "Debug." Instead, it built for Release. Solutions:- Right click on the project -> Build Configurations -> Build Selected... and select Debug.AND- Setting Debug as the active build and right click on the project -> Build ProjectThese solutions would build for Debug AND clear both of the above issues. As in the hammer icon -> Debug would actually build for Debug and the Debug Configuration would build before flashing and debugging.

I have a requirement to implement CAN based bootloader in my STM32h503rbt6 controller. Right now iam working on the testing of Flash functions which i have written on my own.My flash write, read and erase all are working fine.but when iam erasing flash sector wise,here comes the problem.after sector 7, from sector 8 onwards with y function i cant abe to erase.but i want full memory controll over my st controller flash.then only i can decide which part of flash i can use for my bootloader and which part of flash i can use for my application.HAL_StatusTypeDef Flash_Erase_Sector(uint32_t sector) { while (FLASH->NSSR & FLASH_SR_BSY); if (FLASH->NSCR & FLASH_CR_LOCK) { FLASH->NSKEYR = FLASH_KEY1; FLASH->NSKEYR = FLASH_KEY2; } /* Clear valid flags only */ FLASH->NSCCR = FLASH_CCR_CLR_EOP | FLASH_CCR_CLR_PGSERR | FLASH_CCR_CLR_WRPERR; FLASH->NSCR &= ~FLASH_CR_SNB_Msk; FLASH->NSCR |= FLASH_CR_SER; FLASH->NSCR |= (sector << FLASH_CR_SNB

STM32CubeIDE is creating a new folder inside ".stm32cubeide\.jxbrowser-7.41.4" everytime STM32CubeIDE launches.It would be nice if the application cleaned up its junk, at least deleting old profile subfolders, as each one eats up 75MB.I just manually deleted over 75 of them dating back to October. 

hi i re-downloaded STM32 Cube IDE but i cannot find <create STM32 Project> I downloaded this sw over and over but nothing changed :(please help me with this 

Hello guys. I'm currently trying to use the dsp libraries of the cmsis pack with no success.My device is a WBA55CG nucleo board and the version of my ide is 1.19. I tried to download the cmsis package manually, by selecting embedded software package maneger and then from local/url and successfully installed the packages. (CMSIS 5.9). I enabled core and selected CMSIS from source and dsp. I enabled dsp and core on mx configuration->middleware and hit generate. I tried to inlcuded the arm_math lib on my program to see if the installation was successful and if cube could build my program..... aaaand all hell broke loose.../Middlewares/Third_Party/ARM_CMSIS/Source/SVMFunctions/SVMFunctions.c:29:10: fatal error: arm_svm_linear_init_f32.c: No such file or directory 29 | #include "arm_svm_linear_init_f32.c" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. ../Middlewares/Third_Party/ARM_CMSIS/Source/TransformFunctions/TransformFunctions.c:29:10: fatal error: arm_bitreversal.c: N

Hi,when generating a project for the STM32G484 using STM32CubeMX (6.16.1) and create a project and code for this. I cannot seem to get it to build (and/or debug) in STM32CubeIDE (2.0.0).What am I missing here?Thanks,ErX.

In my STM32CubeIDE, the labels and tabs are displaying as garbled text (random characters). This makes it difficult to navigate and use the IDE.My current development environment is as follows.STM32CubeMX v6.7.0, STM32CubeIDE    Version: 1.15.1     Windows 10 19044.1766    JAVA_VERSION="18.0.2.1"How to solve these garbled code problems? I have reinstalled this IED many times。

Hi, I have a problem with my CubeIDE installation that is that I cannot create a stm32 project(the option that integrates with CubeMX) I can only create the followingI've installed it from the shell script from the generic Linux download, I'm using arch Linux(btw).I've reinstalled it at least 3 times now, also went to Help -> Install New Software, used this site: And installed everything down the STM32CubeIDE section. 

I'm planning on moving from STM32F103 for more speed, so in advance of getting a board I thought I would try building an app for the STM32G431... so I found an small example project online that was using an OpAmp feature.Having got that compiled ok in STM32CubeIDE I backported my app source code into the project (which went ok), but compiling it was missing some definitions for HAL UART structures.Looking at "Drivers/STM32G4xx_HAL_Driver" in my original project and comparing it with "Drivers/STM32G4xx_HAL_Driver" in the new project I see that its missing some files like "stm32g4xx_hal_uart.h". Is it possible to force STM32CubeIDE to regenerate the Drivers subfolder from scratch?I always find switching a STM32CubeIDE project between different MCUs a harder job than it should be, e.g. it would be nice if there was a combo box listing MCUs in the project properties.  

Hi and happy new year... I'm a complete beginner, and I'm facing a major problem.I've tried creating a new project in CubeID for an STM32F401CEUx.But the project "STM32 Project" doesn't appear in the list of new projects.The closest thing I find is one called "STM32CubeIDE Empty Project," and when I create a project using this template, the initial image of the chip where I configure the pins doesn't appear, and the IoT file isn't in the project tree either.Why could this be? 

Hello,I'm facing very strange issues with STM32CubeIDE 2.0.0 under Linux Debian Trixie/Forky.I'm running Kernel 6.17.11+deb14-amd64 with Plasma 6.5.4, KDE Framework 6.20.0 and QT version 6.9.2 in Wayland.First issue is with debugger. I can start the firmware in debugging mode, runs but after few "Step Into" and "Step Over" commands the debugger is getting stuck. I doesn't take any commands anymore.If I use "Restart" or "Terminate" or "Terminate and Relaunch" is starting again and again I can use few times "Step Into" and "Step Over" Second issue is with windows ordering after using for a while STM32CubeIDE: it breaks completely the windows orders under Plasma and the only solution is to logout and login back and restart all apps.I didn't get this issue with any other apps, except STM32CubeIDE.

An intermittant bug... (as it happens it doesn't occur as I am reporting this issue).Open up a STM32CubeIDE project.Navigate to a project Source Folder, e.g. XYX...Core...SrcHighlight a source file, e.g. "main.c",right-click "Copy", right-click "Paste". Click "Ok" to the suggested filename "main2.c".Double-click "main2.c" to edit it, You can't cut or modify any text in the file, nor type in any new text.Close STM32CubeIDE and launch it again... the file is now editable.The bug appears perhaps 2% of the time, not a deal breaker but a bit annoying.  

I created a support ticket for this issue but haven't heard back yet, but I wondered if anyone else has seen this issue before. I have been having an issue with my STLINK-V3MINIE for some time now. When I set and hit a breakpoint, the program will often not start again no matter what I do. I am using arm-none-eabi-gdb with OpenOCD to debug a STM32H750, and will set a breakpoint or watchpoint in my code, and once it is hit, I am not able to get the target to continue again using "continue" or "step" commands in gdb. Even after deleting the breakpoint, the issue will remain and the only way to get the target to respond normally again is to reset the program with "monitor reset halt". The image I attached shows hitting a breakpoint, deleting the breakpoint, then not being able to continue I tried upgrading the firmware on my STLINK-V3MINIE, this did not fix it. It is an official STLINK-V3MINIE that I bought from ST, not a clone.Things that I tried that did not work as advised by

Due to issues with text selection and copy/paste in STM32CubeIDE 2.0, I reinstalled the operating system (I was previously running a beta version) and moved to a stable release (Tahoe 26.2 (25C56)) on an Apple Silicon Mac (M4). I then downloaded and installed STM32CubeIDE and STM32CubeMX. The installation completes successfully, but when launching either application, an error occurs and the tools fail to start. Has anyone experienced this issue or knows the root cause? Any insights would be appreciated.

When I build  my project in "Debug" mode all works fine, if I build the project in "Release" mode an error appears: C:/ST/STM32CubeIDE_2.0.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.13.3.rel1.win32_1.0.100.202509120712/tools/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -llibarm_cortexM7lfdp_math.a: No such file or directory GCC linkerLibraries (-l):                     libarm_cortexM7lfdp_math.aLibrary search path (-L):   "${workspace_loc:/${ProjName}/Drivers/CMSIS/Lib/GCC}"    Any help ?Thank you
