STM32 MCUs Software development tools

Hi, I have configured My RTC with LSE of 32.768Khz for STM32G0B1CETxAnd In NVIC Setting RTC & TAMP interrupts are enabled..All these are done using Cube MxAfter HAL_RTC_Init() call from main;  RTC_TAMP_IRQHandler is getting called continuously. Time and alarm is configured after  HAL_RTC_Init(). which is not even called.Any inputs could be helpful.Thank youSuraj Prem

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? Is it set anywhere else? /** * @brief GPIO Initialization Function * None * @retval None */ static void MX_GPIO_Init(void) { GPIO_InitTypeDef GPIO_InitStruct = {0}; /* USER CODE BEGIN MX_GPIO_Init_1 */ /* USER CODE END MX_GPIO_Init_1 */ /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOE_CLK_ENABLE(); __HAL_RCC_GPIOF_CLK_ENABLE(); __HAL_RCC_GPIOC_CLK_ENABLE(); __HAL_RCC_GPIOA_CLK_ENAB

 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 all,I am a newbee, and so far I finally did successfully in creating my first prog with STM32CubeIde.I am able to produce .bin, .elf, .hex files for my project with CubeIdeI am able to read and produce a bin file of the program in flash in my board with the CubeProgWhen I want to flash back to the board using DFU mode, I noticed that bin file doesn t have any segment starting address, elf file instead, have a starting address 0x800000If I load a bin file, do I have to specify the correct programmer address I mean 0x800000 in cubeprog, because it doesn't itself :( 

I'm trying the new VS-Code extension 3.5.1, but I end up in the HardFault_Handler function during the initialization, in the "MX_USBX_Device_Init" function. The same project works correctly when using the "cortex-debug" plugin (separate VS Code profile to avoid conflicts).It's a very simple project where I did the very minimal config to enable USBX, and "UX Device HS -> Device Class HS -> HID -> MSC" on my STM32U5A5AJH6Q. The IOC file is attached.It crash in the function "USBD_FrameWork_MSCDesc", at line /* Append Endpoint descriptor to Configuration descriptor */ __USBD_FRAMEWORK_SET_EP((pdev->tclasslist[pdev->classId].Eps[1].add), (USBD_EP_TYPE_BULK), (uint16_t)(pdev->tclasslist[pdev->classId].Eps[1].size), (0U), (0U)); 

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

Hey all,I wanted to check if there’s a way to program multiple PCBAs in parallel using multiple ST-Links. I have 6 PCBAs and 6 ST-Links, but since we currently have only one DLL, we can target only one ST-Link at a time, this makes the overall programming process quite time-consuming.If anyone has a solution or any suggestions, please let me know. Your help would be greatly appreciated.Thanks and regards,Lakshya

hi everyone, i got a problem when i use MX generate code and open folder，i try to reinstall and didn't solve。it shows not responsible

Hi, we are working on an open-source library OS in Rust for embedded architectures, result of a collaboration between the French research institution INRIA and the Freie Universität Berlin, called Ariel OS. Our OS currently supports a variety of STM32 MCUs and we expect the list to grow with time.To streamline user experience, we would like to provide some ways of automatically generating the clock configuration for the STM32 MCUs. We are envisioning a utility where users simply ask for specific frequency ranges for specific clocks and this utility would figure out the correct dividers/multipliers/multiplexers to use to comply with the users requirements.To achieve this, we would need to be able to recreate the entire clock tree logic. As far as I understand, CubeMX recreates the clock tree in software and is able to calculate frequencies based on the chosen/defaults values of the clock parameters for any MCU using some kind of configuration file. For our project we would need to

Hi, I am using the Nucleo-H7A3ZI-Q Board and was trying to use the DMA to transmit SPI frames. Only creating simple SPI TX Circular DMA request works when generating the code from STM32CubeIDE 1.12.1 (with STM32CubeMX 6.8.1). I get two linker scripts STM32H7A3ZITXQ_FLASH.ld and STM32H7A3ZITXQ_RAM.ld. In the STM32H7A3ZITXQ_FLASH.ld, I get this memory sectionMEMORY { ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K DTCMRAM1 (xrw) : ORIGIN = 0x20000000, LENGTH = 64K DTCMRAM2 (xrw) : ORIGIN = 0x20010000, LENGTH = 64K RAM (xrw) : ORIGIN = 0x24000000, LENGTH = 1024K RAM_CD (xrw) : ORIGIN = 0x30000000, LENGTH = 128K RAM_SRD (xrw) : ORIGIN = 0x38000000, LENGTH = 32K }When I was generating the code from STM32CubeMX (alone) to generate code with the "toolchain/IDE" option set to Makefile, the same code does not work.

Hi,After STM32CubeMX update to the 6.15.0 version, the HAL_DMA_ConfigChannelAttributes() calls get removed in the generated FSBL and Appli (secure) code while no changes in the *.ioc file have been made.Could you please elaborate on the behavior and consequences? 

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. 

Hello, what do I wrong?  I am trying to setup a new stm32f7xx project, with CMSIS_V2 and LWIP.I use only the CubeMX application at the version 6.15.0, I have tried several hours to get this setting but nothing working.If I select CMSIS_V1 the LWIP use the RTOS (WITH_RTOS is Enabled), if a switch to CMSIS_V2 it is disabled.All settings are CubeMX default. CubeMX says CMSIS_V2 is working with F7.  Is this a bug at the CubeMX? Or what do I wrong?  thanks a lot. 

While fiddling with H745 board to investigate how dual core works, after modifying option byte to BOOT_CM7 = 0 and BOOT_CM4, STM32CubeProgrammer (nor STLINK-gdbserver) refuses to connect to the board with "Error: No STM32 target found". The ST-Link itself is okay. Here is a log from the programmer.22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : No STM32 target found! 22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : Error: No STM32 target found!How do I regain access to the board?

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 everyone,I am trying to debug my CubeMX (CMake/Ninja) project based on the STM32H7A3VG in VSCode.When I use the elf-File in Ozone I can step through the code as expected. With VSCode the debugger seems to start, but no debugging is possible.Other controller like STM32F446x or STM32F407xx I can debug with no problem.I adapted the launch.json for the STM32H7A3VG and its M7 core also with the help of chatgpt but something is missing, I guess.Here is my launch.json:---------{    "version": "0.2.0",    "projectName": "STM32H7A3VGTest",    "configurations":[        {            "name": "Debug STM32H7A3VG (J-Link)",            "type": "cortex-debug",            "request": "launch",            "servertype": "jlink",            "serverpath": "C:/programme/SEGGER/JLink_V854/JLinkGDBServ

Hello, I have opened someone else's STM32 project in VSCode but I'm getting errors and I can't build. I think it has something to do with CMake, the extension is not asking me to generate a CMAKE config. Do I have to genereate a new project from IDE/MX to work with CMAKE or can I generate the CMAKE files in the exisiting project? Also, it seems that the extension wants you to disable clangd or cpp intellisense extensions because they conflict with the extension's intellisense, is there a way to enable the extention intellisense only for STM32 projects?Thanks in advance 

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?

Recently I'm trying to setup CLion and STM32CubeMX as I want to switch to a new IDE (By the way, the fact that STM32CubeIDE still doesn't have features like auto-triggered content asist, and that its poor, buggy GUI has bad compatibility with high DPI screen are just annoying). However, when I successfully generate the project in CubeMX and open it in CLion, CLion refuses to compile the project no matter what. I tried the bundled MinGW, CubeCLT1.18 and the older 1.16, and also CLion 2025.1, 2025.1.2, 2025.1.3. All didn't work. Up till this point I've been using CubeMX 6.15, and so I tried to install and use the older version (6.14.0). Everything suddenly works then. The project compiles without problem. Therefore, I suspect that there are some problems in the newest release of CubeMX (6.15) that are generating faulty CMake files.Here are some screenshots of what happened. I used the same version of CLion and CubeCLT in the same configuration on two projects generated by CubeMX6.15 and
