STM32CubeMX (MCUs)

In STM32CubeMX v6.17.0, in the left side of the Pinout & Configuration panel, if the mouse cursor is within a table that lists peripherals, the scroll wheel doesn't do anything. I expect it to scroll the window. You need to move it outside of the table but still within the bounds of the "Categories" tab in order to scroll up and down. This is super annoying because it means you have to have the cursor on the far left or far right of this window otherwise a table will appear when scrolling and the mouse wheel will stop working.In the screenshot, having the cursor anywhere in the red box will stop it from scrolling. I expect it to scroll the green scrollbar.

I'm using a STM32F407VG (actually a disc-1 board). I've set I2S2 in full-duplex master mode and generating the MCLK out on PC6 for an external slave codec. So far so good.Now i want to set SDIO interface in full-duplex 4-bits mode but CubeMX throws a warning about a partial conflict with I2S master clock out. Frankly i have no clue about it, can i safely ignore the warning? 

I created a motion_fx for stm32h562 from CubeMx. The auto generated motion_fx.h file does call (line 135)size_t MotionFX_GetStateSize(void);​But the code does miss the include #include <stddef.h>Which results in the following error:unknown type name 'size_t' motion_fx.h ./Middlewares/ST/STM32_MotionFX_Library/Inc line 135 C/C++ Problem 

Hi,In STM32CubeIDE/MX versions 1.19 and 6.15, I configured HRTIM, and it worked fine without any errors in CubeMX. I have updated STM32CubeIDE/MX to versions 2.1.1 and 6.16.1, and I have noticed the error messages shown in the pictures below.The dead time is not used, but when set Output 2 state MX displays the message "Set Sources: nothing to set as Dead Time is enabled, Output2 signal is defined based on Output1 Configuration Set Sources". The project operates like before the update, but it is not possible to add new Set Sources (I can only change the number of Set Sources to zero). How to understand this behaviour?Krzysztof  

In a recent release (not sure which one) the option to select USER_PHY was added to the platform settings under LWIP.I need to implement a different PHY for a LAN9374. It is basically identical to the LAN8742. The only issue is that the LAN8742 init code fails unless modified slightly. If I select LAN8742 and modify the file I can get it working but as expected every time I regenerate the project the modifications get overwritten. Where is the documentation on how to implement a USER_PHY?

STM32G491Code generator generate wrong order of calls for SPI initialization for LL driver: LL_DMAMUX_SetSyncRequestNb  calls after LL_DMAMUX_EnableSync

 Hello,I am encountering an issue with the ST example projects "BLE_p2pServer" and "BLE_DataThroughput_Server" for the NUCLEO-WBA65RI board.After generating the code using STM32CubeMX (version 6.17), the project does not include all the required source files. As a result, the compilation fails immediately, even before making any modifications to the code.I enabled the option:"Generate peripheral initialization as a pair of '.c/.h' files per peripheral".The main issue is that the following file is missing:"stm32wbaxx_ll_utils.c" .It seems that some HAL/LL driver files are not being generated or included properly in the project.Could you please adv

Hi,I found an issue when generating code for a BLE application with STM32CubeMX v6.17.0.In particular, I have a service called DataTransferService with three characteristics:DataStreamCommandControlTransferStatusThe DataStream characteristic is configured as a notification with a fixed value length of 100 bytes.When I try to increase its length up to 250 bytes and regenerate the code, the following functions in custom_app.c are removed:Custom_Datastream_Update_Char()Custom_Datastream_Send_Notification()I have attached the .ioc file for reference.

I'm trying to configure and generate a project with STM32CubeMX for the STM32WBA5MMGHx BLE module.When enabling the STM32_WPAN middleware, the ADV_TRACE module gets automatically enabled under Utilities. This in turn requires to enable at least one UART/LPUART peripheral, otherwise type UART_HandleTypeDef is undefined and compiler throws and error:../../Core/Inc/app_conf.h:304:8: error: unknown type name 'UART_HandleTypeDef'; did you mean 'RTC_HandleTypeDef'? [build] 304 | extern UART_HandleTypeDef huart1; [build] | ^~~~~~~~~~~~~~~~~~ [build] | RTC_HandleTypeDefThe STM32_WPAN throws a warning about not configured/wrong Platform Settings.Is there any possibility to configure STM32_WPAN without ADV_TRACE enabled?Used STM32CubeMX version is 6.17.0 and WBA firmware v1.19.0 and cmake project is generated.

The list of #include in the main.c file is lost when regerating stm32cubemx with new GPIO config :Previous : /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2026 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "main.h" #include "string.h" #include "exti.h" #include "embedrt_debug.h" #include <stdio.h&gt

When I click this button, my mouse keeps spinning but the program does not open, and there is no error message. I tried using Refresh Data, but it had no effect.

Hi ST Support Team,I am using MXCube for STM32U5A5VJ. I have enabled the RTC, and cube generates the following Init Function. In this way, everytime I restart the controller, the RTC date is gonna be overwritten. In practice, I would like to have the bracket at line 9 down in line 21. Thank you for your support.Best Regards, Gianmarco Cerutti void MX_RTC_Init(void) { ... /** Initialize RTC and set the Time and Date */ if(LL_RTC_BKP_GetRegister(RTC,LL_RTC_BKP_DR0) != 0x32F2){ LL_RTC_BKP_SetRegister(RTC,LL_RTC_BKP_DR0,0x32F2); } RTC_TimeStruct.Hours = 0x0; RTC_TimeStruct.Minutes = 0x0; RTC_TimeStruct.Seconds = 0x0; LL_RTC_TIME_Init(RTC, LL_RTC_FORMAT_BCD, &RTC_TimeStruct); RTC_DateStruct.WeekDay = LL_RTC_WEEKDAY_MONDAY; RTC_DateStruct.Month = LL_RTC_MONTH_FEBRUARY; RTC_DateStruct.Day = 0x11; RTC_DateStruct.Year = 0x25; LL_RTC_DATE_Init(RTC, LL_RTC_FORMAT_BCD, &RTC_DateStruc

@Mahmoud Ben Romdhane I am still seeing this on ST Cube MX 6.16.1 when generating for the STM32F723E-DISCO target. This is using the latest STM32F7 package, 1.17.4. Attached is my IOC file if that's helpful.I know its a trivial fix but wanted to report this is ongoing.

The CubeMX suddenly can't generate some .h files such as stm32f103xb.h, core_cm3.h, stm32f1xx_hal_rcc.h ..., I tried to use legacy CubeMX to generate but still the same.How to fix it?Left picture is what it should look like ,and the right one is the wrong one.

Hi,during porting the USBX as host stack to an stm32h7 I was getting an error indication,that a semaphore was used during interrupt context (OTG_HS_IRQHandler).For my opinion, it is wrong to call the generated code out of the ISR without decoupling the context. How did you solve the problem? Is there a posibility in cubemx the generate code with decoupling the context?.

I'm trying to download Cube MX, Cube Programmer, and Cube IDE. I registered and activated the license, but it won't download. I've tried using different browsers (Chrome, Firefox, Edge) without extensions. I accept the License Agreement, but nothing happens. I tried it as a guest user, too, but it won't download. I really need the programs, what should I do?

We used to define STM32 pinout in STM32CubeMx since it's aware of all the possiblilities of the MCU.Then we manually need to transfer the pnout into Altium Designer Schematic. And to keep those in sync when design changes.So we want to automate that step if possible.Thus the question: How can I Import pinout generated from STM32CubeMx into Altium Designer Schematic.

Im trying to setup FreeRTOS with the new STM32N6.According to https://github.com/STMicroelectronics/x-cube-freertos, the new Nucleo board for the STM32N6 is mentioned as supported.But in the CubeIDE, when trying to enable the FreeRTOS middleware, it says that the new nucleo board is not supported. And the docs also only mention AzureRTOS as supported.Is FreeRTOS supported through the CubeIDE? Or only AzureRTOS? 

Hello,I found a CubeMX database issue affecting STM32H747 dual-core projects using FreeRTOS with CMSIS-RTOS V2.EnvironmentMCU: STM32H747Cube/HAL: STM32CubeH7 1.13.xCubeMX: 6.17FreeRTOS: 10.6.2ProblemTwo FreeRTOS configuration parameters are not present in the MicroXplorer Configuration settings and are not retained in the internal IOC model:configUSE_SB_COMPLETED_CALLBACK configUSE_MINI_LIST_ITEMBecause of that, code generation can produce invalid output in FreeRTOSConfig.h such as:#define configUSE_MINI_LIST_ITEM ( valueNotSetted ) #define configUSE_SB_COMPLETED_CALLBACK ( valueNotSetted )This breaks the build and/or downstream FreeRTOS code.Editing the .ioc manually does not solve it permanently, because CubeMX overwrites the .ioc on regeneration.

I am using a G474RE nucleo board and i have 2 separate interface boards which i ca connect to it. One board requires a VREFBUS of 2.5V and the other  2.90 . Currently i modify the .IOC file and select the appropriate VREFBUS, compile the code. So currently i have 2 separate .elf files, one for each scenario. I will want a single code version so that on start up based on the status of a switch connected to a GPIO, it will configure the correct VREFBUF value. The attachment shows my setup for the 2.90V internal voltage reference. Thanks David  

  I don't use this Tx Buffers Nbr. Instead, I use this Tx Fifo Queue Elmts Nbr for sending. The difference between the two is just that one is manually sent and the other is sent by hardware, right? Why does the software give me a pink prompt for Tx Buffers Nbr, stating that the number of Tx Buffers Nbr plus the number of Tx Fifo Queue Elmts Nbr must be 32? What does this mean? Help me, I'm about to cry.I don't use this Tx Buffers Nbr. Instead, I use this Tx Fifo Queue Elmts Nbr for sending.

I upgraded to 6.17 this morning an have already had to roll back due to a bug in how it now generates fiels for FreeRTOS.Under the FreeRTOS (Include parameters) options I have this vTaskDelayUntil set to Enabled.  This now changes the define name in the user config file (Core/Inc/FreeRTOSConfig.h) to be #define INCLUDE_xTaskDelayUntil 1which is correct for the updated freeRTOS version, but in the file (Middleware/Thrid Party/FreeRTOS/Source/CMSIS_RTOS_V2/freertos_os2.h) it has not been updated so it now it throws an error stopping my projects from building. There are other places where vTaskDelayUntil has also not been updated to xTaskDelayUntil. This needs to be fixed.  

Hello, I got following problem.STM32CubeMX is unable to properly generate .project file for STM32CubeIDE. After clicking "GENERATE CODE", MX is copying library files, generating .h and .c files, but no .project file. Following nullpointer exception can be found in log file. I already tested different versions of JAVA - no change. I attached error messages, MX log, and .ioc file. Anyone managed to fix this?  2026-03-15 10:27:00,707 [ERROR] ToolchainGenerator:531 - java.lang.reflect.InvocationTargetException: null at jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:115) ~[?:?] at java.lang.reflect.Method.invoke(Method.java:580) ~[?:?] at com.st.microxplorer.plugins.projectmanager.model.ToolchainGenerator.CallMethod(ToolchainGenerator.java:406) ~[?:?] at com.st.microxplorer.plugins.projectmanager.model.ToolchainGener

Hi ST,I have a STM32H7 project with FW_H7_v1.12.1 and MX v6.16.1, everything is good so far.But after migration to FW_H7_v1.13.0, I can't generate FreeRTOS code any longer.All FreeRTOS-related code are deleted and MX stay loading icon when I click FREERTOS component.I tried uninstall MX and then install latest MX v6.17, but the same.I also tried install X-CUBE-FREERTOS component, but still the same.Please find my ioc file as attachment.Is there anything I can do?Thank you very much.BRs,-Engin

Split from Inconsistent pin naming - this is a separate suggestion.I would like the option to have the define of a particular GPIO port, or all defines, not typecasted to a pointer. So only the base address as an uint32_t (or uintptr_t). This would make using it in C++ in constexpr easier. Because reinterpret_cast and pointer comparison is not allowed in a constant expression. This should be an additional define for backwards compatibility.  #define CLK_A_GPIO_PIN GPIO_PIN_0 #define CLK_A_GPIO_PORT GPIOF #define CLK_A_GPIO_PORT_BASE GPIOF_BASE // <- for use in constexpr In C++ it would be much easier to do things at compile time using templates and constexpr t
