STM32CubeIDE (MCUs)

Hello,Is there a trick to get the Build Analyzer to produce data every time the code is compiled?   It seems like the only way I can get it to update the window is if I change something in the linker script file and recompile again.   Is there an easier way or a setting that needs to be set?thanksMatthew

Trouble Report: STM32G474 FD CAN RX Interrupt Causes HardFault Due to VTOR Left at 0x00000000 Platform Details----------------- Microcontroller: STM32G474VETx- IDE: STM32CubeIDE- Version: 1.16.0- Build: 21983_20240628_1741- Startup project: Standard CubeMX-generated application with FDCAN peripheral using interrupt-based RX- RTOS: None (bare metal)- Debugger: ST-LINK / OpenOCD Problem Summary =============== Using the CUBEMX tool I have used the alternate pins FDCAN3_RX to PA8 and FDCAN3_TX to PA15. The GPIO init is pasted below. It fails to configure PA8 and PA15. Have I misunderstod something here?

 FDCAN Clock Divider can silently change your actual CAN bit rateI ran into an issue on an STM32G474 where FDCAN3 would not receive any messages on a 250 kbps CAN bus. Error counters (REC) climbed rapidly, indicating a timing mismatch.After a lot of debugging, I discovered that the FDCAN Clock Divider was set to the clock from my FDCAN1, which was DIV8  even though CubeMX was showing a baud rate of 250 kbps in the GUI. By tricking the GUI by setting the FDCAN3 to 2Mbps instead of the 250kbps I needed it all started working properly, i.e. 250k times 8 is 2M.Here is a useful function to look at what is going on in CAN on stm32s......  void Print_FDCAN_Config(FDCAN_HandleTypeDef * hfdcan) { uint32_t prescaler = hfdcan->Init.NominalPrescaler; uint32_t sjw = hfdcan->Init.NominalSyncJumpWidth; uint32_t ts1 = hfdcan->Init.NominalTimeSeg1; uint32_t ts2 = hfdcan->Init.NominalTimeSeg2; uint32_t mode = hfdcan->Init.Mode; uint32_t framefmt = hfdcan->Ini

Hello,I am currently trying to develop for the STM32H573RIT6 microcontroller, however after generating a new project I run into an issue where I am unable to compile any code due to main.h attempting to include "stm32h5xx_hal.h", but it fails to compile as it fails to locate that file. The only file that I was able to locate was "stm32h5xx_hal_conf.h", but replacing that in the "main.h" file still fails to compile as it cannot find "stm32h5xx_hal_spi.h" and "stm32h5xx_hal_gpio.h". system_stm32h5xx.c also attempts to include the "stm325xx_hal.h" file as well and as a result errors. 

I am using an SD card with STM32F415. The MCU periodically enters STOP mode.Currently, I observe the following behaviour in the IDE related to SDIO:- Before enabling SDIO for the first time, the current consumption in STOP mode is as expected (around 180 µA), and the 48 MHz clock is greyed out in the Clock Configuration diagram in the IDE.- As soon as I enable SDIO in SD 1-bit mode, the 48 MHz clock becomes active in the Clock Configuration diagram, and the current consumption in STOP mode jumps up by 1 mA. This is true even if I disable the call to MX_SDIO_SD_Init() in main().- When I later disable the SDIO interface in the configurator, the 48 MHz clock remains active, and the current consumption in STOP mode remains with the additional 1 mA introduced when enabling the SD card for the first time.I see no way of disabling the 48 MHz clock, either temporarily (before going to STOP mode) or permanently (by disabling the SDIO altogether in the IDE). I suppose this is also the reason why

Hey all, first and foremost I'm new to the embedded systems space, I've been trying to get my feet wet with a hello world project but for some reason with Cube 1.17.0 I'm missing the "MyST" login tab at the top of the screen. I've tried Re-installing thinking I had done something wrong during the original process to no avail. For further context I have a Linux system with the IDE installed and code generation worked properly on it however I found endless issues with the debugger and decided it might be an issue with Linux so I gave up and installed it into my windows machine to see if that helped with anything and now this is my new issue. To get around this issue as the ide suggested I navigated to "Help->stm32Cube Updates->Connection to my ST" and logged in through there and tried to create a new project and still it gave me the error as if I wasn't signed in, tried the same method again and it told me my session had expired, I haven't tried code generation just yet because as

Hi everyone, I am trying to program my board but suddenly I am getting Target unknown error 32 Error in initializing ST-LINK device. Reason: Unknown. Please check power and cabling to target.this error. I tried connecting my board with STM32CubeProgrammer and it successfully connectedThis thing is only happening with IDE, I also updated the STLinkV3 firmware, restarted my PC several times and also changed my cable but I am still getting the error. Kindly help. 

I’m using STM32CubeIDE v1.19.0 (Build: 25607_20250703_0907) on Linux, and I’ve run into a recurring issue when creating a project from an existing .ioc file.When I go to:File > New > STM32 Project from existing .iocand select a valid .ioc file (that opens correctly in STM32CubeMX and works on real hardware), the “Targeted Project Type” field changes automatically from STM32Cube to “Empty”, and the resulting project has no .ioc linked and no code generated.This issue happens even with:- Fresh .ioc files- Clean, empty directories- New workspaces- Verified CubeIDE 1.19 installationHowever, if I open the same .ioc in **STM32CubeMX (standalone)**, perform a **Save As**, and generate the code with toolchain set to `STM32CubeIDE`, then import the project manually into CubeIDE — everything works fine.This same issue had occurred in CubeIDE 1.18.x and seems to persist in 1.19.0.Importantly, this workflow **used to work fine**, and suddenly stopped working **without any visible or intentio

I have an STM32G474 project that has been working for some time but the latest update doesn't generate code from the .ioc config GUI.If I make I make changes in the editor and select generate code, the pop flashes quickly and goes away but no code gets generated. I've tried this on a couple of Windows computers with the same result. 

Hi All,I started to have issue with CubeIDE. It "crash" / "close itself" after few moment after startup. Log is attached. I have tried this:Uninstalled CubeIDE 1.18.1 and I have done clean install 1.19.0, without successI have created new workspaceI have disabled checking updates in CubeIDE, but without any successI have restarted computer (Win 10 Pro 22H2), temporally disabled AV software and firewall, no Windows KB update was installed before issue started (only Edge-WebView2 update 1.0.3351.48)Thank you for any adviceRegards,Jan

I am learning to use the PWM Input mode to measure input frequency. I am using examples from the internet to help me along.In my .ioc file SYSCLK is set to 8MHz and with a prescaler set to /8 my HCLK and APB1 are set 1MhzIn the examples I studied in the callback routine Frequency is calculated either:1:   1000000 / capture_valuewhile another uses this method2:  SystemCoreClock / capture_valueMethod 1: works but in case you eventually need to change the prescaler you also need to change the constant.Method 2: sounds more robust but when I hover over "SystemCoreClock" in main.c a window comes up stating that SystemCoreClock is set to 8000000 anyway. What variable do I need to use to ensure that the value used in the calculation is in fact HCLK or APB1?

Hello everyone, I am on Windows 11 and am using STM32CubeIDE version 1.18.0 (also tried on verison 1.18.1). I have logged into myST within the software as well (through Help->STM32Cube Updates -> Connection to myST). I can edit the pins in the .ioc file just fine, but I cannot open the code editor; I keep getting this particular error. I have tried closing and reopening the app, restarting my computer, deleting and reinstalling and downgraded the version to try to verify if the problem was in the software. Can someone help me? Screenshot of the app:   

Hi everyone.I've got a question about a strange aspect of my project and the compiling process.I have some files to be compiled for my project. The compile process goes fine, everything is correctly compiled and looking both on console output and build target, all the required file are correctly compiled.What strangely happens is that if I look to the size of the .text section at the end of compile process, it is equal to only 96Bytes which are a very small size infact my code doesn't work correctly both on debug and on release.Any suggestions where can I look to try to fix the issue? I've already given a look to the linked files (headers) and source location tab (all the required folders are into the sources list), same for .make files, and .map files Wich contains all the required files. The only strange file is the .list file that is very small and, looking to the disassembly cose, there isn't all the code I was expecting but only a small piece. Any advice?

I have already updated my CubeIDE to the latest version 1.19.0 available on the official website. After writing the code with it, I attempted to download it to my F407VGT6 via STLink, but the download has never been successful. It always prompts "Could not verify ST device!" When I replaced one board with another, I was able to successfully download. The only difference between the two boards is that the silk-screening of the two VGT6s is slightly different. One has a small circle with "e3" inside and can be downloaded, while the one that cannot be downloaded has "e4" in the circle. I wonder if CubeIDE has not yet adapted to this chip. Has anyone encountered the same situation? I hope to get your solution!

 Hi everyone,I'm currently debugging UART communication (USART3) between an STM32G070CBTx and my PC using Hercules terminal (serial software). The setup seems to be working. I can see data being sent and received. I'm monitoring the TX_buffer and RX_buffer via Live Expressions in STM32CubeIDE.The issue is that when I try to view the contents of these buffers as ASCII characters, the debugger shows this error:72 '<error reading variable: Converting character sets: Invalid argument>'However, the buffer values are correctly shown as decimal ASCII values (e.g. 72 for 'H', 101 for 'e', etc.).A photo of the Live Expression view showing the errorTX_BUFFERRX_BUFFERA screenshot of Hercules receiving the correct string My question is:Is there a way to fix or work around this character set conversion error in the Live Expression window?Is it related to how the debugger is interpreting the memory or something I can configure in STM32CubeIDE?Any insights or workarounds would be grea

Hi everyone! I’m new to LoRaWAN development on STM32WL55jc1 boards and need help importing the LoRaWAN_End_Node example correctly in STM32CubeIDE. I’ve tried multiple approaches (downloading from GitHub, manually copying files, etc.), but I keep running into configuration errors or missing dependencies. Could someone guide me step-by-step on how to do this properly? Specifically:*Where to download the official example from?Key settings when importing the project (e.g., toolchain, paths).Common pitfalls and fixes (e.g., incorrect paths, library issues).Thanks in advance for your patience! :smiling_face_with_smiling_eyes: 

I'm running IDE version 1.13.1 on MacOS 11.7.1 on a MBP with a dual core 2.8Ghz i7. Unlike every other IDE / CAD package that I use, STM32CubeIDE pegs my CPU really high and spins up the fans even when doing NOTHING. As in, there is no project open, no editors, no HW configuration, literally NOTHING.Why?

I am trying to debug my code, but it just ain't working the way it's working in e.g. the STM32CubeIDE intro-video on Youtube; I'm getting "No source available for main()", instead of Eclipse displaying where in the code it's actually at.I haven't changed any of the default-settings, other than where my workspace is and yes, I have build a debug-version instead of release-version and yes, I do see "-g3" - flag enabled in the compilation-console.How do I fix this?

Hello,I recently run into problem with not being able to debug my applications any more.I use STM32CubeIDE (and Atollic) without major problems for years now, but suddenly debugging does not start.I can flash the the device through the Run button. When I click debug it is also flashed but than progress stops at around 95% percent and stays there forever. Logs do not look the same every time so just some examples here.  I tested multiple applications with 3 programmers  (ST link V2, ST-link V2 from 3rd party, ST-link on Nucleo Board) connected to multiple custom devices that previously worked. I use 4-wire programming (V, SWDIO,SWCLC,GND)However when using Nucleo board directly it starts normally.I experimented with dubug configurations, reinstalled the IDE, drivers, tried older versions, nothing seems to make a difference.Thank you for the support.regards Jeronym

Dear STM32 Support Team,I am trying to create a new project in STM32CubeIDE, but I encounter a few issues. First, I cannot select the "STM32Cube" option under the Targeted Project Type section when starting a new project.To work around this, I tried generating code through STM32CubeMX after completing my .ioc configurations. While the code is transferred to STM32CubeIDE, many essential files are missing, and the project does not build or run properly.Additionally, STM32CubeIDE displays an error message saying: "Fix the highlighted errors and try again." However, I cannot identify what these errors refer to, as nothing is clearly highlighted.I am using the latest version of STM32CubeIDE, and I have already uninstalled and reinstalled the software, but the problem still persists.Could you please help me resolve this issue?Best regards,Emre MERCAN
