STM32CubeIDE (MCUs)

Hello!I am trying to configure the project to run X-Cube-AI. When opening the attached try_ai.ioc file in STM32CubeIDE 1.17.0 the window freezes. Also tried to open it in STM32 CubeMX 6.13.0, no success. The board is NUCLEO-N657X0-Q.Could you please help me to troubleshoot this issue?Regards, David Alami

Dear STMicroelectronics Support Team,   I am working on the STM32F407G-DISC1 (STM32F4 Discovery) board and I am unable to watch printf() statement in SWV ITM Console output in STM32CubeIDE.   To enable the SWO trace output, I referred to the user manual and identified that SB12 (SWO) was in OFF state by default. Following the recommendation, I removed the 0-ohm resistor between the SB12 pads on the backside of the board and directly shorted the pads using solder to connect the SWO signal to PB3. I also attached an image of the soldered SB12 pads for your reference.   Here are the board details:   - **MCU Model**: STM32F407VGT6   - **Board**: STM32F4 Discovery   Could you please advise if any additional configuration or hardware action is needed for the SWO functionality to work properly? Request you to send me a reference video link for any modifications mentioned by you.   Thank you for your support.   Best regards,   Vakati Heman

CubeIDE version 1.2.0 Cloning a git repo with a .ioc file in it, how to generate code?When right clicking the "Generate code" is grayed out. The only method that has worked seems to be opening the .ioc file, toggling a checkbox to generate a change and then saving to cause code generation. Is there a way to generate code when ever I want? or force the code generation even if there are no changes detected?

The Toolchain Manager takes 5–10 minutes to load the toolchain list, even with only a few installed.It happens every first time I open it after launching the IDE.If I close it and reopen it during the same session, it loads instantly.But if I restart the IDE, the delay returns.Is this normal behavior?If so, is there anything that can be done to speed it up?STM32CubeIDEVersion: 1.18.1Build: 24813_20250409_2138 (UTC)

Hello all,I have been hanging on to an anctient version of ubuntu for a LONG time because I need to use STM32CubeIDE,sadly, IT required me to update because you know..... security and stuff.I was resisting because I knew I would get this error:Could not determine GDB version using command: arm-none-eabi-gdb --version arm-none-eabi-gdb: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directoryAnd I had tried to install the required file before, even add a symlink to the so.6 version in the past with no luck. So today I made the update, and when I hit debug right after re-installing the Ide, i got the lovely message.So it this it for me? Do I need to bug IT to get me a new PC simply to run an old version of ubuntu or is there some way for me to actually run this?I am guessing no as it seems to be part of the ide...My current version is: base: Ubuntu 24.04 nobleAnyone else have any luck with this? I read some other posts about this

Hi I am new to STM32. I am porting a design from NXP's Crossover Processor RT to STM32H7xx. I have a Nucleo H743 eval board that i started using and testing.I have created a new project in Cube IDE V1.18.1, selected H743,  and selected various modules and configured IOs for those. I intend to use ethernet in RMII mode, QSPI Bank1, SDMMC1, 2xI2C, 4xSPI, 4xUART/USART, USB FS.I get conflicts other than the pinouts. I guess that it is because of Clock/DMA or some internal resource. I read the reference manual (RM033) and data sheet of H7, also pdfs of QSPI, SDMMC, I2C etc. But could not find out what to check and correct. In parallel I am doing the hardware schematics too. Need help/pointer so that I can address the limitations and create a correct hardware design.Thanks.

Hello,I am using an STM32F103VCT microcontroller and the EEPROM emulation library. I write data with the EE_WriteVariable() function and read it back with EE_ReadVariable(). However, whenever I download new firmware to the MCU via ST-Link V2 in STM32CubeIDE, the entire flash memory is erased—including the regions where I stored data using EE_WriteVariable().Is there any way to download or debug new firmware without erasing the flash pages used by the EEPROM emulation?For reference, I’m running STM32CubeIDE version 1.18.1. Any suggestions would be greatly appreciated.Thank you!

Hi, I am trying to interface on board microphone in STM32H757I-EVAL. I am trying to use PDM format data. In STM32 Cube IDE, I am trying to configure PE2 as PDM_CLK but it is not listed in the pin configuration. I have attached the image. 

Has anyone successfully used the BSD addon for netxduo inside CubeIDE?  I followed the instructions at the top of https://learn.microsoft.com/en-us/azure/rtos/netx/netx-bsd/chapter2 (the #define TX_THREAD_EXTENSION_3 int bsd_errno needed a trailing semi-colon) but the netx timeval and fd_set definitions conflict with the CubeIDE environment (/ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/select.h and /ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/sys/_timeval.h).My only reason for using BSD is to to implement ModbusTCP with libmodbus .  I would gladly opt for a native netx implementation of ModbusTCP if anyone knows of one.

 How to import assembly files and compile them in STM32CudeIDE ?When I create a .s source file in a project, I cannot even save the file, and STM32CudeIDE only reports an error:Save failedAST is empty

I am writing multiple libraries that use either I2C or SPI for communication.  I recently discovered that the STM32F4xx family had an interesting "feature" that will take the SPI NSS signal low and keep it low until the SPI module is disabled versus toggling the NSS line based on data transmission when hardware control is specified for the NSS signal.  I want the libraries I am writing to be "smarter than the average bear" so a user who has no knowledge of any particular MCU's quirks can easily use the library.Taking a generic SPI Flash memory module as an example and using the aforementioned STM32F4xx family MCU, is there a "define" specified within the IDE or the HAL's that will allow me to do something similar to the following code snippet?  I found something similar to what I am trying to achieve in the system_stm32f4xxx.c file that is auto generated by CubeMX/CubeIDE.  I am just looking for a way to cover an entire family of MCU's.#include "stm32f4xx_hal.h" #in

STM32CubeIDE and STM32CubeProgrammer exhibit different behavior when flashing an MCU. Specifically, "gaps" in memory sections described in the linker script are flashed to a device with 0xFFFF when using the IDE and 0x0000 when using the programmer. For example, this will be the case for the few addresses after ".isr_vector", but before ".text".I noticed this when programming an STM32G474RE to perform a CRC on its own flash on startup as part of data integrity check. I appeared to get different CRC results depending on whether I had programmed the unit through the IDE or the CubeProgrammer (despite using the same .elf file, ST link, and PCB). Ideally, I think STM32CubeIDE should probably be updated to match the behavior of STM32CubeProgrammer for consistency.This was done using STM32CubeIDE version 1.13.0, STM32CubeProgrammer version 2.14.0, and STLinkV2.

 This IDE has gone into some crazy mode where each window maximizes itself on the screen/. I've tried clicking every single maximize/minimize/restore button, closeing the app, restarting the computer.....This worked and suddenly broke.Is there some way to make this thing reset back to it's default state?   

I've been receiving this error for several times please help me trying on f446re

I am using CubeIDE version 1.16.1 to program and flash a STM32F433 MCU.I am using a SEGGER J-Link flasher.When I try to run the application I get the following error:I have tried to manually set the workspace toolchain to local in the toolchain manager.When I open the toolchain manager, I get an error that it has failed to fetch the toolchain list, in addition to four repositories that it cannot read: Ignoring the message and setting the local toolchain as it follows  I get the same error when running the code on the MCU:What should I try to do to fix the error?

  Subject: Missing .h Files After MC Workbench Code Generation (MCSDK 6.3.2 + STM32CubeIDE 1.13.2) Message: Hello ST team, I am currently working on a sensorless BLDC motor control project using the B-G431B-ESC1 board and STM32CubeIDE 1.13.2 in conjunction with the Motor Control Workbench (MCSDK 6.3.2). After generating my project (6-step sensorless control) through the Workbench, I observed that the .c source files are properly included under Middlewares/MotorControl, but the corresponding .h header files (bus_voltage_sensor.h, ntc_temperature_sensor.h, etc.) are missing in the include paths. I verified that these .h files are located at: C:\Users<user>.st_workbench\projects<project>\MCSDK_v6.3.2-Full\MotorControl\MCSDK\MCLib\Any\Inc\ However: They are not copied or symbolically linked into the STM32CubeIDE project structure. As a result, functions like VBS_GetAvBusVoltage_V() or NTC_GetAvTemp_Celsius() cause "undefined reference" errors unless these headers are man

Hello everyone,I choose the stm32 H755ZI (develop board) because I need a dual core microcontroller and a fast one. I never worked with dual core before (I did with STM32 and CubeIDE) so i let everything for default mode and tried to debug my project with this tutorial:https://www.youtube.com/watch?v=jI1k6p-fduE&t=254s It worked and it seem time to change the settings too my project. My settings for the clock:RCC settings: and some other stuff with timers etc. Then I wanted to debug again and the M4 core passed out and the M7 core ended up in this while loop in system clock config:  I tried multipel things: 1. lower clock config 2. lower clock config in combination with SMPS instead of LDO, but nothing works. Can anyone help me please? Thanks!! Greetings from Holland    

Hi,I am trying to do this tutorial: https://community.st.com/t5/stm32-mcus/how-to-implement-the-usb-device-composite-class-in-stm32-using/ta-p/645017 but I can't find Azure RTOS in Middleware and software Packs. I have already downloaded the packs for azure H7 and placeit here ( C:\Users\XXXXX\STM32Cube\Repository\Packs\STMicroelectronics) but nothing in CudeIDE.Is enybody have an idea how I can do ?Thanks,G.

Hello, my CubeIDE stuck while looping trying to access  the marketplace where I need to download and install EGit plugin. During this "looping" the window cannot cancel the operation , neither close the window - typical of Java' "runaway" ... After  probably 15 min it reported "internet connection failure" yet the Marketplace window is still looping and unresponsive to any input neither to cancellation attempts. I am using internet non stop while the marketplace is still searching... Also immediately prior to accessing marketplace I logged-in and accessed the STM site to check for updates and got a fast positive reply.This problem with marketplace continues since yesterday.... does it have to do with new updated version 1.18.1 of CubeIDE which I updated recently?Does anybody else have this problem with new IDE ?

 Hi everyone, I’m using a MacBook with an Apple M1 chip running macOS Sequoia 15.2. I recently updated STM32CubeIDE to version 1.18.1. My target board is a Nucleo-32 STM32L031K6T6. Initially, I created a new project using STM32CubeIDE and, without modifying anything, successfully debugged the automatically generated code. I noticed that the .elf file was correctly generated in the Debug folder. Then, I added a very simple code snippet to send a value over the serial port, just to test functionality. However, when I ran the code, I got the following error: /Applications/STM32CubeIDE.app/.../ld: oc4.elf section `.text' will not fit in region `FLASH'/Applications/STM32CubeIDE.app/.../ld: region `FLASH' overflowed by 6884 bytescollect2: error: ld returned 1 exit statusmake: *** [makefile:64: oc4.elf] Error 1 After this error, the .elf file disappeared from the Debug folder. It seems that STM32CubeIDE generates the .elf file initially but deletes it after.&nbsp

Hi,I have project in cube ide 1.18.1. with stm32h523.The generated code void MX_I2C1_Init(void) has LL_I2C_EnableFastModePlus(I2C1); at the end despite the configuration is set to normal (not fast or fast+). This looks like generator bug because I don't see the same error in stm32g071 project.I explicitly need the normal i2c mode setting for its sink current limit. Otherwise this bug may actually cause a chip damage due to over current.Can anyone confirm if this is indeed a bug?It is easy to reproduce. just create empty project with i2c and set the driver to LL. the 100kHz normal is the default.I tested it with real cpu and even if I replace it with LL_I2C_DisableFastModePlus it still seems to sink >20mA so it does not behave as the datasheet suggests. I did not find specification for current in normal mode, but I would expect something above 4mA based in i2c protocol spec and safe margin below 25mA which is the damage limit according datasheet.

I'm using STM32CubeIDE 1.17.0 and it was working fine but today when i open the board selector, i see an ads instead of the boards list.

Hello,I have the very excellent book "STM32 Arm Programming for Embedded Systems" by Mazidi, Chen, Ghaemi.  It is from 2017.  The book uses Keil, which I am very happy to use, and it has very nicely written code which I fully understand (so nicely written!).I am having trouble getting a project going in Keil because in the book when you make selections in 'Manage Run-Time Environment' during the project set up is says to tick 'System Startup for STMicroelectronics STM32F4 Series', but in my version of Kiel, it says something like 'use Cube IDE/MX' and no option to use 'System Startup for STMicroelectronics STM32F4 Series'.Could someone help with this? I do NOT want to use Cube IDE etc. all that software its horrible.Thank you in advance!

I am using the following setup:- STMCubeIDE1.6.1 on Windows 11I see the following behavior- Opening the IDE with the default Toolchain and my Project for 1.6.1 works fine and build. However, I need to use the GNU Tools for STM32 (7-2018-q2-update)- I install it with the Toolchain manager which works. Then I have to restart the IDE for the Toolchain to become active.- After the restart the IDE is missing the usual C Project settings like Build C/C++ and the Toolchain manager. (see Image). Furthermore I get the 'Missing builder indication under the 'Builder' settting.- Strange enough using this Toolchain works with newer IDE versions like v1.10.1 for other projects but I need to use v1.6.0 or v.1.6.1- Only reinstalling the IDE can fix the issue.
