STM32CubeMX (MCUs)

Hello ST, Today, in two separate threads, I've had to walk two separate newcomers to STM32 through the pitfalls of trying to trigger a DMA to an arbitrary peripheral from a timer event. The threads are:what-are-gpio-events-how-do-i-connect-an-event-to-a-peripheral andspi-dma-request-triggered-by-timer-compare  I myself had to struggle (using the G431) not that long ago to make sense of what the CubeMX generated code does, and why it isn't usable.HAL functions HAL_TIM_IC_Start_DMA/HAL_TIM_OC_Start_DMA hardcode the DMA peripheral register to which read/write is performed, thus they are n

Hi Team,Please help add support for MDK-ARM version 6.22. Currently highest selectable Min Version is V5.32Thanks in advance.

I am trying to configure my stm32l475 as a composite device combining a mass storage device and com port. I read that there should be an option in the "class for FS IP" dropdown to create a composite device, however I do not have that as an option. The only options listed are disable, audio device class, communication device class, download firmware update class, human interface class, custom human interface class, or mass storage class. I am using STMCube IDE v. 1.18.1, and I ran the "check for updates" option to make sure everything is up to date. Why is composite device not listed as an available option in STMCube ide?

HiFor other STM32 (I checked a STM32L452 and STM32F469) I could enable the Flash Instruction prefetch by setting “Prefetch Buffer” to “Enabled” in the RCC settings. This then set PREFETCH_ENABLE to 1 in stm32F4xx_hal_conf.h.The STM32H562 also as a Prefetch Buffer, but I cannot find the “Prefetch Buffer” option in CubeMX , and PREFETCH_ENABLE is always 0. Was the “Prefetch Buffer” moved or is it missing?As a work around I can manually call __HAL_FLASH_PREFETCH_BUFFER_ENABLE(), but having the option back would still be nice.I use STM32CubeMX Version 6.14 with the Firmware Package V1.5.0 to generate a STM32CubeID

If I select STM32CubeIDE as the toolchain, I encounter the following error during compilation. However, if I switch the toolchain to EWARM, the project compiles without any errors.I’ve attached the .ioc file and build log for reference. Could you please help analyze what might be causing the issue?Thank you in advance for your assistance! 

I'm using STM32H7R7, and I want to configure clock with 24MHz HSE(CPUCLK@600MHz), but the CubeMX can't resolve the error automatically. What should I do? Thanks!

When generating code with CubeMx version 6.14.1 there is a new bug (compared to version 6.13.0 where it worked fine).MCU: STM32U5A5QJIxQPeripherals: ADC1/2 and/or ADC4RCC Clocksource: SYSCLKWhen you change parameter setting in ADC_Settings "Clock Prescaler" it has no effect on generated code. There should be following code (was generated like this in version 6.13.0):LL_ADC_CommonInitTypeDef ADC_CommonInitStruct = {0}; ... ADC_CommonInitStruct.CommonClock = LL_ADC_CLOCK_ASYNC_DIV4; LL_ADC_CommonInit(__LL_ADC_COMMON_INSTANCE(ADC1), &ADC_CommonInitStruct);The ADC clock prescaler setting is common for all ADCs and DAC, but in version 6.14.1 there is no code generated which sets the prescaler anywhere!   

Hello,I use CubeMX V6.13.0 (now the newest version).I have find out a bug in the configuration wizzard from the FDCAN with the STM32G473.When I chose:FDCAN1, Clock Divider = "Divide kernel clock by 10"FDCAN2, Clock Divider = "Divide kernel clock by 1"Then start the FDCAN1 and start the FDCAN2, then the FDCAN2 works not with the correct bitrate.The problem is: CubeMX does not know the µC has only one "Clock Divider".See RM0440, Rev 8, at 44.4.37 (page 2011):"Note: The clock divider is common to all FDCAN instances. Only FDCAN1 instance hasFDCAN_CKDIV register, which changes clock divider for all instances."If I choice for FDCAN1 a other Clock Divider as by 1, the the bitrate calculation for FDCAN2 and FDCAN3 is bad. Please fix this bug in CubeMx,Thanks a lot.Best Regads Markus  

When generating code with stm32cubemx, an interface pops up, saying that I don't have the MDK-ARM toolchain installed, but I can burn the code normally with keil5 on my computer, why

I am having trouble creating custom queue sizes and making them work with the Heap Usage tool within CubeMX.  But I found a workaround until the bug gets fixed.I created a queue using a custom item size (the message_data_t type is defined in my code):The code generation is correct:   /* Create the queue(s) */ /* creation of UsbRxQueue */ UsbRxQueueHandle = osMessageQueueNew (16, sizeof(message_data_t), &UsbRxQueue_attributes); /* creation of BufferQueue */ BufferQueueHandle = osMessageQueueNew (8,

When trying to run the webservice example for the STM32-F429ZI-Cube board, I'm getting the following error:Nx_WebServer Application started.. IpAddress: 192.168.23.100 FX media opening failed : 0x21There's nothing about this error in the README.md file, it suggests that I should write to RAM with the command <INSTALL_PATH>STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -c port=swd -w <INSTALL_PATH>web_content\web_demo.binBut I can't find the web_demo.bin fileI tried with chatGPT, but it took me down a darker path and away from the solution :)What am I doing wrong in this example?

Hi developers.I have the same issue as many others, which has been posted already 4-5 times and marked as "solved" in some of them, but it is not at all the case.The CubeMX on launsching shows the first screen (splash) and then disappears.It worked a couple of times after intallation, then again after de-installation/reboot/re-installation/reboot.Watching the Task-Manager it shows a process called "OpenJDK Platform binary" which starts at high CPU and ends up to 0% but with around 200MB RAM reserved. And this can take place many times, collecting a bunch of idle/useless processes. I run it with Windows 10, latest version of JAVA and CUBE at this moment, but with a previous version on both I used to have the same issue.While unistalling, I try to find every single file I can, so that I delete each trace manually, but every time I re-install it, it still "knows" which was my last opened projects and which uC I use.&n

Hi ST,There are 2 bugs in Initialization of VREFBUF.in STM32CubeIDE V1.11.0.I use FreeRTOS, but it shouldn't have any inffluence on these bugs.1.) At function main, the firsr call is to Hal Init and when VREFBuF ist activated, in function HAL_MspInit, Enabling the SYSCFG Clock sets the HiZ bit of CSR. the call to HAL_SYSCFG_EnableVREFBUF sets the ENVR bit in CSR and waits for VRR set which indicates the Reached the desired voltage. This will never happen. Only when I clear the HiZ bit manually, the VREFBUF wil reach the voltage (measured on VREF+ Pin), the VRR wil be set and it can continue.2.) in function HAL_SYSCFG_EnableVREFBUF, it waits for Tick Count to reach VREFBUF_TIMEOUT_VALUE (wait max 10ms) but no count of HAL Tick will happen. The Tick is initialised before, but it seems that something ist not configured correct or too late. There is no Tick increment at all.The combination of above bugs ends in Dead System. Nothing

STM32CubeMX generates a different .ld file depending on the selection under Project Manager -> Toolchain/IDE, when it should not.Here are two examples, the first for CMake, and the second for STM32CubeIDE. I added them both to a .zip file.STM32C071RBTX_FLASH.ld was generated when selecting STM32CubeIDE.STM32C071RBTx_FLASH.ld was generated when selecting CMake.ProblemThe files should not have been regenerated. IT should have been the same name, with the same content. That two different files are generated shows for a bad implementation in STM32CubeMX for how it generates the .ld file.

I met a problem when using CubeMX to modify the CSI to start the camera module, but it shows that the CSI cannot be adjusted correctly. I want to know how to solve this problem.

Dear ST Community,I’m currently working on a CMSIS-Pack for STM32 and would appreciate your guidance.I initially created a CMSIS-Pack named WiFiBluetooth-STM32, version 1.0.0. After adding new features, I created an upgraded version 2.0.0, which includes additional components and bundles. I kept the previous release (1.0.0) listed in the pack’s release history as per CMSIS-Pack standards.However, when I load the upgraded pack (2.0.0) into STM32CubeMX and open an existing.ioc file that was using version 1.0.0, I get the following warning:Warning: The CMSIS-Pack JDP.WiFiBluetooth-STM32.1.0.0 is not present in the repository or on the user disk.I’m still new to STM32CubeMX and CMSIS-Pack development, and I’m not sure how to handle multiple versions correctly so that older .ioc files don’t b

I am using a w25q256jvfq ainbond chip and cube mx to setup octospi1 on the stm32h723vgt6. However after the HAL_OSPI_INIT and HAL_OSPIM_Config commands, what other commands and settings should I write to make it match the characteristics of the w25 winbond chip?Thank you

I am using Winbond's Quad SPI NOR Flash memory (W25Q128JW).Which of Micron or Macronix should be selected for the memory_type of the OCTSPI setting parameter of cubeMX?

I have such dev board and try to run it as virtual com port. I created project cubemx, enable only usb as device in CDC mode. After generating and running project with next small fixes I run it on board.int main(void){//....skip while (1) {   /* USER CODE END WHILE */    const char* str = "Test\n";    CDC_Transmit_FS((uint8_t*)str, 5);    HAL_Delay(1000);   /* USER CODE BEGIN 3 */ }gtkterm connects to the dev but no received and sent data.When I started to debug interrupt handler I found that usb device always in USBD_STATE_DEFAULT mode since start and state isn't being changed instead of ISRs..USBD_StatusTypeDef USBD_LL_SOF(USBD_HandleTypeDef *pdev){ if (pdev->dev_state == USBD_STATE_CONFIGURED) {   

Hi ALLI'm playing with a STM32C011J6Mx on  a plane breakout board.Sorry if this a basic question, new to using the SMT32 , last time I played with MCUs was 6809 CPU :)I wanted to use I2C and SWD, to use both I need to move the I2C1_SCL to it's alternate pin, when I CTL+ left click on the  PC15 (I2C1_SCL) it shows PA8 has an alternative.But when I select PA8 , I2C_SCL , is not listed has an alternative function.

I'm trying to get the BLE_p2pServer example working using a Makefile setup on an STM32WBA55CG board. I copied the .ioc file and opened it in CubeMX, changed the toolchain setting, but now I'm stuck at the "copying libraries files" stage. Not sure if I messed something up—sorry if I misunderstood something or did something wrong along the way.I tried following the official tutorial, but ran into a bunch of issues, error messages during flashing, version mismatches (even after rolling back), and my MCU not showing up in the application toolbox.I'm currently using the latest CubeMX, and while everything works fine in CubeIDE, I'm trying to move away from it and build with Makefiles.

Hi,I am using the Nucleo-N657X0-Q board and here is what I have done so far:Generated a CubeMX projectEnabled FSBL, Secure Application, Non-secure Application and ExtMemLoader projectsEnabled XSPIM, XSPI2, EXTMEM_LOADER, EXTMEM_MANAGERGenerated codeOpened the project up in CubeIDEAnd this is where I get stuck. Since the project generates 4 sub-projects, which one do I run and on which boot configuration (BOOT0 JP1 and BOOT1 JP2)?I just want to get the non secure application to run, I have added a line of code to turn the blue LED on to verify that the code is running. Purpose of this project is to understand the project structure and its method to get the code running.Can someone please describe the steps I need to follow and in which order these needs to be done?And I also want some feedback on the steps I have performed so far. Was it even needed to generate the EXTMEM_MANAGER sub project

I am using NUCLEO-H743ZI which has STM32H743ZI on it. In the 'Device Configuration Tool' under the 'Project Manager'->'Advance Settings' there are options to set how I want to generate HAL calls. I basically want to set all of them 'Visibility(Static)' so they are called at the 'beginning' of main function.However as soon as I hit 'Save' or 'Generate Code' the visibility of 'MX_USART3_UART_Init' disabled and 'Not Generate Function Call' is selected automatically. I can of course call the function manually but this unpredictable behaviour is concerning...

Hi,I think I have found a bug in CubeMX v6.12.0.I have an STM32U595 with USB OTG HS.My USB peripheral is set to use the HSE as it's clock (not PLL1):However, when I try to set the oscillator source for PLL1 to the HSI, CubeMX gives an error declaring that "Only HSE is possible when OTG_HS is using PLL1", which would be try, except OTG_HS is configured to use HSE, not PLL1:

I am using CubeIde for the first time.First test - run minimal program with HAL from CubeIDe Configurator, under debuggerSimple program, only SYSTICK and uart , but SysTick_Handler() is not trigged at all .And function HAL_Delay hangs because uwTick is always 0. Tried with setting brakepoint inside handler - no resultsUsed HSI, SYSCLK 16MHZ, Cortex System Timer 16MHz,RCC GPIO and USART1 - HAL configured.here is main() generated from cubeide (I removed comments):-----------------------------------------------------------int main(void){  HAL_Init();  SystemClock_Config();  MX_GPIO_Init();  MX_USART1_UART_Init();  HAL_Delay(100); // here program hangs, when reaches HAL_Delay function. uwTick = 0  while (1)  {  }}-----------------------------------------------------------
