STM32CubeMX (MCUs)

For a project I am using the STM32U073 and for testing the development board with the STM32U083. I have encountered several issues in CubeMX and perhaps also in the hardware: The code that CubeMX generates for the low power timer contains a typo. Line 4214 says "tmpccmr2 = hlptim->Instance->CCMR1;", but it should read CCMR2 instead LCD_MspInit() should be called during startup (probably in MX_LCD_Init() in main.c), but that does not happen. __HAL_RCC_PWR_CLK_ENABLE() is not called at startup, but it needs to be. LCD_IRQHandler() in stm32u0xx_it.c does not call a weak function like every other interrupt handler, but requires code in the USER CODE BEGIN/END block in there. In stm32u0xx_hal_msp.c, at line 568, the alternate function of the timer pin needs to be set to enable a PWM on timer 2: GPIO_InitStruct.Alternate = 1; Finally, the encoder on low power timer 1 is behaving very weird. Apparently, even though this is not very clear from the reference manual, the "match" event ha

Hello ST,I'm encountering an issue when generating an STM32G474 project using STM32CubeMX V6.14.0. When using the default Scatter File (stm32g474xx_flash.sct) generated by CubeMX in Keil, the program gets stuck at HAL_Init(). However, if I check the "Use Memory Layout from Target Dialog" option in Keil to let it generate the sct file instead, the program compiles and runs normally.This problem didn't occur in the previous version, V6.13.0. Could you please look into this and verify if there's an error in the Scatter File configuration generated by CubeMX V6.14.0 for STM32G474 projects?To give you a better understanding of the issue, I've included some relevant code snippets below:stm32g474xx_flash.sct (generated by CubeMX V6.14.0); ********************************************************************************* ; *** Scatter-Loading Description File generated by STM32CubeMX/LinkerGenerator *** ; *********************************************************************************; LR_IRO

I use the STM32L496ZG. When generating the files using STM32CubeMX it also generates MX_Device.h which contains several defines. When using LPUART1 with DMA it also generates defines like:#define MX_LPUART_RX_DMA_DMA_Handle #define MX_LPUART_RX_DMA_Instance DMA2_Channel7The CMSIS Driver for the UART however uses:#ifdef MX_LPUART1_RX_DMA_Instance #define UART6_DMA_USE_RX UART_DMA_USE_RX #else #define UART6_DMA_USE_RX 0 #endifSo using MX_LPUART1_RX_DMA_Instance is not the same as MX_LPUART_RX_DMA_Instance and causes the DMA to be disabled.MX_Device.h should contain LPUART1 instead of LPUART with regards to the DMA defines as it also does with the Pin and IRQ defines.

 I followed this tutorial: https://www.youtube.com/watch?v=xbWaHARjSmk and this github link: https://github.com/micro-ROS/micro_ros_stm32cubemx_utils to create a custom board support for micro-ros. When i compile my project, I get the following errors:====================[ Build | stm32f4_uros.elf | Debug ]========================   /snap/clion/234/bin/cmake/linux/x64/bin/cmake --build \/home/tzinkii/Workspace/Embedded/stm32f4_uros/cmake-build-debug --target stm32f4_uros.elf -- -j 3\   -- Minimal optimization, debug info included\   -- Configuring done\   -- Generating done\   -- Build files have been written to: /home/tzinkii/Workspace/Embedded/stm32f4_uros/cmake-build-debug\   [ 2%] Linking C executable stm32f4_uros.elf       /usr/lib/gcc/arm-none-eabi/10.3.1/../../../arm-none-eabi/bin/ld: error: stm32f4_uros.elf uses VFP register arguments, /home/tzinkii/Workspace/Embedded/stm32f4_uros/micro_ros_stm32cubemx_utils/microros_static_libr

Hello st forum,I'm currently working with STM32G0B1VCI6, I'm trying to configure the ADC1 channel but it is not working properly. I need to convert 11 channels (10 external and 1 internal channel) and I'm configuring the driver in such a way it can convert all channels at once. According to the documentation, when sequencer is set to not fully configurable, the conversion is done for the enabled channels using their defined channel ID. My plan is to catch each ECO event to save the data until detect the last element (EOS event). However, I'm getting the interrupt immediately with the EOS flag enabled, causing to just read one data instead of 11. This is the configuration I'm using: @Roger SHIVELY 

Hi,I just updated CubeIDE/CubeMX, and after creating a new project, I began configuring the microcontroller. However, when I tried to install FreeRTOS, it didn’t seem to be available. In the older version of CubeMX, there was a FreeRTOS option under Middleware (as shown in the first screenshot from a video), but it appears to be missing now. I did find X-CUBE-FREERTOS, but it doesn’t seem to offer any options like CMSIS_V1 or CMSIS_V2 or any  ther very many parameters that FreeRTOS that in the previous version were available.What happened?1. Is that X-CUBE-FREERTOS, the only or perhaps the preferred option to use/install hrough MX?2. How do I select CMSIS_V1 or CMSIS_V2 and all other parameters like in the older configurator (third screenshot)?3. Are all ST libraries that rely on FreeRTOS now using X-CUBE-FREERTOS?Thanks you  :)Ricko           

cubeMX version 6.13, generating for CMake.Hi there,I'm configuring an STM32H7S3 nucleo board. I can build, flash, run, and debug code.I am adding a UART for logging and now am getting the titled error when generating:Edit: This problem appears the moment I go to the Memory Management tab! If I reset to previous .ioc state, the code generates happily. If I open the project and simply open the memory management tab, this error appears.In tools>Memory Management it looks like my bootloader and app both live in the 64kB onboard flash I want the bootloader to use the onboard flash, and do execute-in-place for code on the provided NOR flash.I have followed these guides, which seem relatively up-to-date:Getting started with MMT(Memory Management Tool) - stm32mcustm32h7s_workshop/1_external_memory/external_memory.md at main · ST-TOMAS-Workshop/stm32h7s_workshopIn particular, section 6.2.5.1 of the first link shows how application flash will be moved to XSPI.

I am using the STM32F723 with custom, self-powered PCB interfaced to a host using USB HS. Everything worked fine with with CubeMX 6.12, but after upgrading to more recent versions, I noticed that the following functions are no longer generated within HAL_PCD_MspInit() (file usbd_conf.c):     __HAL_RCC_USB_OTG_HS_CLK_ENABLE();__HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); and also the corresponding clock-disabling functions in HAL_PCD_MspDeInit(). If I manually re-insert these calls, everything works again.Anyone knows the reason why these functions are not generated, and if I am missing any USB_HS setting in more recent CubeMX versions that should be taking care of this issue? Thanks!

I'm using the latest versions of Keil uVision and STM32CubeMX but when I try to run the CubeMX from the Run-Time Environment screen of Keil, I'm facing with "Error instantiating RTE components" and "Error #545" errors.I think, Keil cannot run the CubeMX because of the launcher error. When I try to run the STM32CubeMxLauncher.exe manually, it pops STM32CubeMX Launcher V1.0.7.0Copyright (C) 2015-2019 ARM Limited (or its affiliates). All rights reserved.*** Error: STM32CubeMX could not be found !CubeMXLauncher termiates with error code 3error. To overcome these errors, I tried many methods.I deleted and reinstalled, changed from "for only me" to "for all users", added the path to the System Environment Variables, tried previous versions etc. None of them worked.

There are 3 bugs reported here:Bug 1:In the FileX parameters GUI, under SRAM Disk Driver: The range for the "SRAM Disk Size" is wrong.  The Address space allows for 256MBytes, not 256KBytes.Workaround - After CubeMX regenerates the code, I have to change the #define manually in the code.Seems to work on my board with 64Mb, (in the example below I have the base address set to C0200000 and using the upper 32MB)Bug-2Under "Software Packs", when we select "LevelX NOR custom inferface", CubeMX doesn't seem to do anything.  We are unable to select the "File System Interface" in the parameters table:If you unselect the LevelX QuadSPI memory interface,The majority of the configuration parameters in LevelX disappear, but is left with an unselectable option (MT25TL01GBug-3Since the Custom driver option does not work in CubeMX, we tried to modify the QSPI driver with the MT25TL01G component.  The problem is there are no    " USER COMMENT" sections in the entire file, so w

Hello,I'm working with the new STM32N6570-DK series. But I can't generate the code with MDK ARM.Thanks,Pierrick Dupont

Hi everyone,I’m currently working on an I2C communication setup using the Nucleo-H753ZI DK but the cubeMx document is for the STM32H743BIT (the MCU for my custom board) and aiming to run it in Fast Mode (400 kHz). However, when configuring the I2C clock speed to 400 kHz, the CLK signal becomes unstable, as shown in the attached image.To ensure the setup is functioning correctly, I ran tests with I2C configured at 100 kHz, and the communication works perfectly in that case. I’ve also included an image of the system clock configuration in case there’s something that could be optimized.  Does anyone know what might be causing the instability in the CLK signal, preventing proper communication at 400 kHz? Thanks in advance for your help!

Hello,In CubeIDE I try to generate RTC code which has decimal parameters. However in code generation I realized that it converted to hex value by itself.You can check screen shots in the attachment. 

I'm using ThreadX on a STM32H743 MCU.  I'm trying to setup a USB Host_only on the USB_HS device, and a USB Device_only device on USB_FS.  The peripheral configuration is okIn the AzRtos settings, it defines 2 seperate byte_pools for each device (one for the host and one for the device).  So far so good.In the USBX configuration, everything seems to be setup properly as well. Everything seems to be configured properly.... so now lets get CubeMX to generate the code....In the app_azure_rtos.c file, CubeMX generates the 2 separate instances of USBx, with 2 memory pools.  (this is good)     /**************************************************************************/ /* UsbX Host Pool */ /**************************************************************************/ #if USE_USBX_HOST == 1 syslog(SYSLOG_INFO, "USB Host memory pool Addr [%08x] size=[%d]", (UINT)ux_host_byte_pool_buffer, (UINT)UX_HOST_APP_MEM_POOL_SIZE); memset(ux_host_byte_pool_bu

Hello, Hope you're well. I started a project with CubeMX to use makefiles. I am able to compile and flash to the board but the code does not run properly on the f4 discovery board. To debug, I used Keil on a windows system and the code is actually working as expected(no changes made). Getting back to using make on my linux machine, the same code does not work properly on the board.I then tried CubeIDE on linux and uploaded the code without any modifications and it works. So it leads me to believe that the problem is the cubemx generated makefile or it could be something else I am unaware about. I appreciate any help figuring this out, thank you.Here is the current makefile ########################################################################################################################## # File automatically-generated by tool: [projectgenerator] version: [4.5.0-RC5] date: [Mon Mar 10 15:10:23 EDT 2025] ####################################################################

Hi,when configuring the LTDC for a 800 x 800 display, the Window Horizontal Start is by default set to 0 which suggests it is a 0-indexed range. So do you set the Window Horizontal Stop and Window Vertical Stop to 800 or to 799? As a separate question, if you use TouchGFX, are those values changed according to what you put on various pages and/or by some settings there? Thank you :)Rick

 Hello everyone,I recently encountered an issue after updating the STM32H5 MCU Package from v1.0.1 to v1.3.0. Some peripheral pin assignments have changed, and previously available pin options are no longer configurable.I started my project in 2024 using STM32H5 Series and developed my hardware based on MCU Package v1.0.1. Recently, I needed a simple peripheral modification and accidentally migrated my IOC file to v1.3.0. After doing so, I noticed that some pin assignments had changed.For example, on STM32H563VGTx, in RMII Ethernet mode, the ETH_TXD1 pin was originally assigned to PB13 in v1.0.1, but in v1.3.0, this option is no longer available (it has been removed from the possible pin mappings).I couldn’t find any release notes explaining why these changes were made. If this is a critical update, I would like to understand the reason behind it so I can decide whether I need to update my PCB design accordingly.Has anyone else encountered this issue, or does anyone have insights

A new question moved from this thread to the correct forum board (to be answered by CubeMx team) Hi If STM32U5 has no support for Ethernet why in configurator i can enable the Middleware NetxDuo?  The question start from this point, NetxDuo support, as documented, the LAN8742 component. The STM32U5 can enable NetxDuo. So STM32U5 can be equipped with ethernet port. If this is not true the configurator cannot give the possibility to enable this sw component.  Looking at example present in other MCU as F4/H7 series, the pins used to drive ethernet component are GPIOs the only difference is the presence of interrupt drived from Eth block. but in the code seems, if im not wrong, not used in connection management.   

 MacOS 15.3.1.  CubeIDE 1.18.0. Firmware STM32Cube FW_U5 V1.7.0.I  was tracking down an issue with SD cards on SDMMC2 on an STM32U5G9N not wanting to start.I found that HAL_SD_MspInit calls:__HAL_RCC_SDMMC1_CLK_ENABLE();instead of:__HAL_RCC_SDMMC2_CLK_ENABLE();

Posted on October 17, 2017 at 12:08When using CubeMX, with STM32L476, for setting LSE drive capability other than 'Low Drive' the setting will not be implemented. This is due to the fact that the write access using bit DBP in PWR->CR1 is not set prior to setting RCC->BDCR value.The code generated in SystemClock_Config is:void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct; RCC_ClkInitTypeDef RCC_ClkInitStruct; RCC_PeriphCLKInitTypeDef PeriphClkInit;/**Configure LSE Drive Capability */ __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW);/**Initializes the CPU, AHB and APB busses clocks */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_LSE|RCC_OSCILLATORTYPE_MSI; RCC_OscInitStruct.LSEState = RCC_LSE_ON; RCC_OscInitStruct.MSIState = RCC_MSI_ON;....}where HAL_PWR_EnableBkUpAccess must be executed prior to __HAL_RCC_LSEDRIVE_CONFIG#cubemx #lse

Hi,looking at the screenshot below of CubeMX in the LTDC, the total Width and total Height are non-editable (i.e. auto calculated) but they are one pixel less?For example, for the attached display datasheet:- Horizontal Sync Width (Editable) = 8 pixels- Horizontal Back Porch (Editable) = 7 pixels- Active width (Editable) = 800 pixels- Horizontal Front Porch (Editable) = 6 pixelsSo the total is 821 pixels instead of 820. But CubeMX displays 820 and it is not editable.Did I miss something? Do I need to change some other setting?Thank you :)
