STM32CubeMX (MCUs)

Cube MX v6.17.0 and even previous version v6.16.1 have a problem generating SystemIsolation_Config for STM32N6.I made a test IOC file. There are 3 SECURE checkboxes checked in RIF -> RIF Aware IPs -> EXTI1:Line 13 for  EXTI13Line 17 for RTC secure-wakeupLine 62 for Wake-up PIN3Screenshot: Generated SystemIsolation_Config(void) in main.c of FSBL contains: /* set up EXTI configuration */ /* EXTI13 line */ HAL_EXTI_ConfigLineAttributes(13,EXTI_LINE_SEC|EXTI_LINE_NPRIV); /* RTC

Hi, I'm trying to access SD cards with an STM32C091 MCU. It seems like FatFS is not supported by default in CubeMX, therefore I looked into FileX. I don't have a need for running an RTOS, so I would like to run FileX in standalone mode. However, the FileX parameters in CubeMX don't contain FX_STANDALONE_ENABLE (see attached). Can anyone offer some insight into the topic?  Thanks you for your time and effort. :) 

Split from STM32CubeIDE version 2.1.0 won't generate IOC project file as this is a new question.Please keep to one question per thread.Thanks both Ghofrane GSOURI & Andrew Neil for pointers. Adopting the method shown in the presentation. I have selected a nucleo development board to create an STM32MX project. I have then created a STM32CubeIDE projecfrom the MX project. Having not written any code yet, I'm getting compilation errors but have no idea why? The errors are relating to files marked with a red x below:

Hello,When generating a basic Bluetooth project for NUCLEO‑WBA55CG using STM32CubeMx 6.17 (and 6.16) with Cmake as the toolchain, the project compilation fails to a missing symbol during the link stage.Here is the error message:le_ctrl.c:(.text.HCI_READ_LOCAL_VERSION_INFORMATION+0x20): undefined reference to `ll_sys_get_brief_fw_version'After investigation, it turns out the issue is caused by the incorrect order of linked static BLE libraries in the generated CMake file "cmake/stm32cubemx/CMakeLists.txt". CubeMX places the Link Layer and BLE Stack libraries in an order that prevents the linker from resolving symbols correctly. Reordering the libraries fixes the issue.Here is the corrected order that resolves the error:# Project static libraries set(MX_LINK_LIBS :stm32wba_ble_stac

Hello,I want to develop a LoRaWAN sensor with STM32WL5MOCHxS, but I can't activate the LSE and HSE clock in CubeMX.Is there a way to make the adjustments in the .ioc?The configuration is possible in STM32WL5MOCH (expired).

Hello ST Community,I am reporting a 100% reproducible build failure when using the latest STM32CubeWBA SDK and tools for the NUCLEO-WBA55CG. It appears the default configuration generated by STM32CubeMX for the BLE_p2pServerThreadX application results in a RAM overflow and linker warnings.Environment:MCU: STM32WBA55CGUxBoard: NUCLEO-WBA55CGSDK: STM32Cube_FW_WBA_V1.9.0STM32CubeMX: v6.17.0STM32CubeIDE: v2.1.0 (with GNU Tools for STM32 14.3.rel1)Steps to Reproduce:Open the example .ioc file located at: STM32CubeWBA\Projects\NUCLEO-WBA55CG\Applications\BLE\BLE_p2pServerThreadX\BLE_p2pServerThreadX.iocIn STM32CubeMX, generate the project for

Dear all and ST Tech Support,I am writing to report a concerning inconsistency I encountered while migrating an older project to the latest version of STM32CubeMX (v6.17.0).Background: I recently reopened a project originally created about two years ago with STM32CubeMX v6.8.1 for the STM32H742VGTx MCU. My goal was to review the Timer 4 settings to use them as a reference for a new design.The Issue: Upon inspecting the Clock Configuration tab, I noticed that the APB1 Timer Clock was displayed as 120 MHz. Based on my original project notes, this value should have been 240 MHz.When I calculated the Timer 4 period using the 120 MHz figure, the resulting timing was twice as slow as it should be. While checking the documentation, I confirmed that Timer 4 is connected to the APB1 bus. In the CubeMX interface:The D2PPRE1 divider w

Hi All,I have been struggling with the CUBEMX (6.17.0). I just want to put here the facts. I am deeply disappointed about the support, but let's suppose it's minor and will be corrected no later than next week.I wanted check and understand the LCD settings with touchGFX since the newest version(4.26) of both did not worked together either. If I tick in the separate c and h files the cubemx generates the wrong files. Also the cubemx will not generate all of the files to build the setup. There are two files between the touchgfx and cubemx in the touchgfx library. Note: The older files from the s7 development board has the comments that it will be generated but just part of it. Note2: I bought the dev board for sure and identified these errors there. It's even bigger error in the STM32H7x7 LQFP176 since the XSPI1 and XSPI2 are available at HEXA_SPI, but it's the same behaviour as above. The right MCU cannot be selected. See the datasheet for the orderin

On STM32Hxx and STM32N6 families I have faced a situation where I need to modify startup assembly code  (startup_stm32xxx.s) to copy code (.text) into ITCM or clear RAM/TCM areas, for clean data or to prevent ECC error (on STM32N6). But next time CubeMX generates code, those changes are overwritten. Same story with SystemInit function in system_stm32xxx.c. So either manual restoration or script must be done. But it's getting quite annoying after several projects. I believe the purpose of CubeMX is to ease development, so I make a feature request:Please add user code begin/end comment sections that exist in main.c also into startup_stm32xxx.s assembly and system_stm32xxx.c source files.For startup assembly I wish the user sections are:User symbols definitions.User data copy.User zero fill.For system file I wish the user sections are quite similar to main.c:User includes.User defines/constants/variables

Hi folks,Well, as the title says, I am having issues installing CubeMX on my M4 Macbook Pro (Apple silicon). I got the email for both the IDE and MX, and I was able to install the IDE just fine, but the link I got for MX seems broken. Is there any other way to download CubeMX? Any help is much appreciated.

Hi all!I'm handling project which use communicate RMII TCP/IP. if i set up CPU clock is 200Mhz as picture 1, the system run OK, i can ping network but my system require CPU clock is 400Mhz. if i set up CPU clock is 400Mhz, the connection between board and serve was intermitten. can you help to take alook and share me solution to set CPU clock 400Mhz and can run RMII.   

在使用最新版本的CubeMX 6.17.0 配置STM32G474QETx系列的HRTIM时，Dead Time明明没有启用，但是显示TA2的置位输出源无法配置。

Upgraded STM32CubeIDE to 2.0.0 and struggling with issues!Installed CubeMX as a standalone program too. Now I'm confused how to create a STM32 project and as usual select C++ as the target language. 1- Should I start from the IDE? There'll be no .ioc file then!2- Should I start from CudeMX? There'll be no option to select C++ as the target language! How to fix it?My purpose is to keep main.c, create .hpp, .cpp files and include the header in main.c to be able to call the functions defined in the .cpp file.

Hello everyone,im trying to send a simple "Hello World" via UART to my Laptop and read in the PuTTY Terminal on my on NUCLEO-H7S3L8 Board, But i tried everything, i cant revieve anything!!! Tried every UART/USART Port in the CubeMX. Nothing on my other NUCLEO-F303RE worked it instantly. These are settings in the CubeMX. i Used USART3 and selected Pins PD8 and PD9. i connected the Board to my Laptop. Set the Baud Rate to 115200 and also looked up the correct COM Port. Here is the test code and see Screenshots below. Maybe something in the CubeProgrammer??? UART_HandleTypeDef huart3; /* USER CODE BEGIN PV */uint8_t tx_buffer[] = "Hello World!\r\n"; ... while (1){

The default clock settings in CubeMX are:High Speed Clock (HSE): BYPASS clock sourceLow Speed Clock (LSE): Crystal/Ceramic oscillatorThis causes the MCU to go into Error_Handler() after going into SystemClock_Config()How to fix:Change High Speed Clock (HSE) to Crystal/Ceramic oscillatorLow Speed Clock I think should be disabled.

Hi all,this issue is related to: https://community.st.com/t5/stm32cubemx-mcus/cmake-project-generation-with-cubemx-cubeai-fail/m-p/770680/highlight/true#M31054. , where it was solved by updating from STM32CubeMX V6.12.0 to STM32CubeMX V6.13.0. However, I have STM32CubeMX V6.16.1, so the error might have reappeared.Background: I try two write code for an STM32N6 and use a CMake project for this. For the setup, I used the following tutorial: https://community.st.com/t5/stm32-mcus/how-to-debug-the-stm32n6-using-vs-code/ta-p/833499 and I can compile + flash the code and get a blinking LED, so the CMake project itself is working correctly.However,

I have a project that uses different MCUs. 99.99% of the code is common for all, so I have different .project, .cproject and .ioc files for each, and use CubeMx to handle the hardware initialization.Currently, it requires manual building: Close the project, copy and replace the files, open the project, trigger code generation and compile.Now I'm trying to automate that.Replacing these files in a script and calling the compiler (headless build) is the easy part.This compiles correctly when the code was already generated with CubeMX.org.eclipse.cdt.managedbuilder.core.headlessbuild -import C:\projects\my_project -build my_project/ReleaseHowever, I was unable to automate CubeMX generationI tried using CubeMx from CubeIDE, and also standalone version, with the same results:C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\STM32CubeMX.exe C:\ST\STM32CubeIDE_1.7.0\ST

Hi,I would like to create a project with CubeMX where I handle files on a SD card with FAT Fs file system using a STM32U5 mcu.When I select the STM32U5 MCU in CubeMX  the FATFS middleware is not available, while If I select other MCUs series like STM32F for example the FATFS Middleware is available.I tried to find the FATFS software package to manually install it into CubeMX but I haven't found nothing.Is FATFS middleware available for STM32US MCUs for CubeMX ? Thanks for your help.  

This had me stumped for a while - Thought I was going blind for a second LOL.PCLK1 and PCLK2 identifiers are missing from the clock tree diagram for the STM32H723.(They are present in the trees for F103, G431, F446 and F723). 

Hello,Regarding CubeMX 6.17, I'm trying to configure a STM32N657 project from scratch.   I'm looking for the driver for the ASP256 SRAM memory chip found in various examples and the STM32N6570-DK discovery board.  If I search the "Software Packs" I can't seem to find the device listed there.  Are these files missing or am i looking in the wrong place?  I found them on Github here: https://github.com/STMicroelectronics/stm32-aps256 but I figured that it should be available in CubeMX (or it would be nice if it was available).   If they are available from CubeMX, how do I extract and add the component to the project? ThanksMatt

CubeMX does not generate .project and .cproject files for cubeIDE, when in CubeMX project it is selected to not use default firmware location, and path set to folder with STM32Cube FW from github. To reproduce:1 Open CubeMX2 Select File->New Project 3 Select chip,  in my case stm32g491ceu64 Open Project manager tab, enter name and location for the project, toolchain - stcubeide5 Uncheck "Use Default Firmware Location", Click Browse and navigate to a folder with github repository with cude FW package6 Go to "Code Generator" sub tab, select radio button "Add nevessary library files as reference in the toolchainproject configuration file"7 Click generate8 Observe folder content in the file explorer - .cproject and .project are missing. CubeMX version 6.16.1

Hello ST Community, I am working on an ultra-low-power project using STM32 MCUs and I have a question regarding the current capabilities of STM32CubeMX. Current Situation: I am aware that STM32CubeMX has an option to "Set unused pins to Analog" to save power. However, this is not sufficient for complex low-power management. In many cases, pins that are actively used in "Run" mode need to be reconfigured into specific states—not necessarily Analog—before entering a low-power mode (e.g., keeping a specific Pull-up/Pull-down for an external sensor, or maintaining a specific Output level to prevent leakage through external circuitry).Currently, CubeMX generates a single initialization function (e.g., MX_GPIO_Init()). To manage transitions for these "used" pins, we must manually write wrapper functions to change their states before sleep and re-initialize them upon wake-up. This manual process is time-consuming and prone to co

With HPDMA configured for SAI1A, no DMA setup code is generated with CubeMX 6.17.0. See attached IOC file as an example. Possible that I'm missing a required setting, but I can't find anything.Edit: Fully deleting and re-creating project seems to have fixed it :shrug:.
