STM32CubeIDE (MCUs)

After model analysis is performed on the model complexity using X-CUBE AI import, the code will be generated.Unknown type name 'ai_i8'Unknown type name 'ai_handle'Creation Failed. I'm getting 19 errors.Has anyone else encountered this? I think an update is needed.

HiI am trying to switch a project from one MCU to the another. I made a new IOC file in MX and then replaced the existing IOC file in my IDE project with my fresh file. The overall configuration is identical except for the pinout, and I use a mix of HAL and LL libraries. The Drivers folder is giving me a boat-load of errors, but all of my user code seems to be fine.I have tried cleaning/rebuilding the project, starting fresh with just the new IOC file, deleting the Drivers folder, saving and regenerating code, and more. The errors won't go away. I have attached the output.What can I do to fix this? Are there any common mistakes or recommended fixes for this situation?

Hello,I am using a custom bootloader for firmware updates on an STM32F7 series MCU.For my process, I need to check the maximum possible application size.Could you please guide me on how I can calculate the application size from the generated .bin, .hex, or .elf files?Also, how can I choose the slots to store the firmware.Thanks in advance!

HelloI am using STM32CubeIDEVersion: 1.19.0Build: 25607_20250703_0907 (UTC)OS: Windows 10, v.10.0, x86_64 / win32Java vendor: Eclipse AdoptiumJava runtime version: 21.0.3+9-LTSJava version: 21.0.3 When I include libraries into my stm32 project I drag and drop a folder (from the windows explorer) int the project predefined folder "Drivers". In a second step I need to set the paths for the C-compiler, C++ compiler and linker seperately.  To do so I open the procect preferences and add a path for the C compiler: In this case The project name is TST_CCS811. and the folder to add is DebugPrintf. I click ok. - path for this folder set.   I continue to do so for the C++ compiler and the linker. The path is always the same - it works - paths set.   Now I want to add the next folder in this case GPIO_CPP. To do so I click on the C compiler again but now - very strange - another project appears in this case TST_BME280 and not the TST_CCS811 which was

I am using an STM32G431CBT6. I wrote code to toggle an LED in stm32cubeide. When I build the project in STM32G431, the LED stays permanently ON. However, when I power the board OFF and ON again, the LED starts toggling. Why is this happening?

In the STM32Cube_FW now is released project using "STM32CubeIDE".I can import the project to STM tools without issue.However, I have a new client which they are using "Eclipse" and does not want to make changes for project.Is there a simple way to import or convert the project which can be used ?I tried just import the project but did not work.Orphaned configuration. No base extension cfg exists for com.st.stm32cube.ide.mcu.gnu.managedbuild.config.exe.debug.1555957249 

Hi,I recently downloaded and installed en.st-stm32cubeide_1.17.0_23558_20241125_2245_amd64.sh.zip onto Debian Bookworm (fully updated). This proceeded without any errors or warnings.On starting the IDE, a blank (i.e. black window) was presented, within the Information Center tab, that did not list any documentation. When I used a previous version of the IDE, this tab then showed links to various documents. Has this functionality been left out of the current version of the IDE ?What do I now have to do in order to get the Information Center tab in the IDE to now show the links to the documentation ?Stuart

Hi everyone,I am currently working on the STM32N6570-DK board and trying to interface a camera to display the output on an LCD screen. I have run the provided example projects, and they are working fine.Now, I am creating a project in STM32CubeIDE and configuring peripherals in the .ioc file. However, I am facing an issue with the DCMIPP and CSI peripheral in the multimedia section. When I change certain parameters, such as the Physical Bitrate in CSI from 600 MHz to 750 MHz, the changes do not reflect in the main.c file.It seems that these parameters are being configured elsewhere. Could someone clarify where these settings are applied, or is this a bug?Also, I noticed that some configurations are present in the MX_DCMIPP_Init() function in this tutorial, but I couldn't find a way to configure them via the .ioc file in the DCMIPP peripheral, such as HAL_DCMIPP_CSI_PIPE_SetConfig.Do I need to set them manually, or am I missing something?I am attaching my project for your refe

I was using STM32CubeIDE 1.10.1 today, and something went strange with the .ioc editor. I was clicking on a pin to set it as GPIO_In, and suddenly the editor seemed to reset as if it had just been opened afresh (frame sizes reset and view position of the pins diagram changed). After that the editor was completely unresponsive and I noticed 'java' was using 100% of the CPU.I killed the java process and tried to restart, but it remained stuck on the splash screen. It has been a while since I updated the IDE so I downloaded 1.12.1 to see if it would help. I found that 1.12.1 will run ok if I set the workspace as an empty folder, but if I try to use the original workspace, then 1.12.1 will also freeze at the splash screen. It seems like something about the files of that project have been tainted.When starting the IDE from the comand line, I get this output:[chris@localhost ~]$ /opt/st/stm32cubeide_1.12.1/stm32cubeide_wayland 1 : Invalid condition id : UX_CORESTACK_Condition cause : null 1

HiI'm building a project from zero and I'm importing all the needed folders manually by going in Project -> properties -> C/C++ General -> Path and Symbols -> Add ...In this way I added all the folder with the needed files. Now, when I build the project I have several errors, as an example: "Undefined Reference to UTIL_TIMER_SetPeriod"However, If I right click on line with error that contains UTIL_TIMER_SetPeriod, the function is correcly showed in its .h file (stm32_timer.h).The point is:- I do have included .....Utilities/timer  folder that contains stm32_timer.h file.- I do have #include "stm32_timer.h" in the .c file that calls the function.- As I said, if I right click on UTIL_TIMER_SetPeriod and open its declaration, the function is corretly found in its .h file.  This issue is happening with several other functions and TypeDefs that are acuatlly found with right click and its path included. How could I solve this?Thanks&nb

Hello,I need to modify an old application which has initially been created with Atollic TrueStudio and was then adapted to an early version of CubeIDE. It's a project from a colleague who has retired.From what I can see so far is that the projects .ioc file was made with a version 6.5 or older (CubeIDE throws an error about it if I try to open it). However, thanks to the project PDF report I was able to recreate the .ioc file with the original device settings. I copied the application sources without modifications and created the project.Unfortunately, the application does not work, so I'm trying to figure out what's going wrong. From what I can see so far is that the interrupts seem to be correctly enabled and the handlers are called (currently I could verify this only for SysTick, for the other interrupts I need to create a dedicated test setup).But the original generated code makes calls to the corresponding peripheral handlers from the interrupt handlers which are either missing in

Hi! I am trying to follow this tutorial to run tflite network: https://community.st.com/t5/stm32-mcus/how-to-build-an-ai-application-from-scratch-on-the-stm32n6570-dk/ta-p/825591But I have faced with an issue on step "3.2.8.2 Configure the X-CUBE-AI middleware". I want to uncheck X-CUBE-AI component from FSBL, and check it on Application. But I see this message(screenshot is attached), when I am trying to uncheck: "Peripheral STMicroelectronics.X-CUBE-AI could not be removed from "FSBL"What am I doing wrong?

I accidentally flashed faulty code to the board in STM32CubeIDE before building it. Since then, I'm constantly getting a GDB Server Error in STM32CubeIDE.However, when I pull BOOT0 to 3.3V and then back to GND, the board temporarily recovers. I can upload code and debug successfully using Atollic TrueSTUDIO and Keil, but not with STM32CubeIDE.In STM32CubeIDE, I still cannot upload any code to the board — it keeps throwing GDB server connection errors, no matter what I try.I've tried every possible solution I could find, but the issue persists. Can you please help me?

Helloim trying to run the code , but in the CUbeIDE there are multiple files are opening and pointing to some coding , its hazzle , tried to find a direct answer , ow to avoid this jumping file when run the code.

Originally a comment on this Knowledge Base article - moved to main forum for better visibility & easier discussionProblem: Hi I am facing somewhat similar issue I have used the SWDIO Pin as Timer Channel to toggle GPIO I can see the toggling of GPIO on oscilloscope but cannot go to the debug mode for the same stm32 cube ide project and also for different project where I have kept the debug PINS (SWDIO and SWDCLK) settings as it isI am trying to erase firmware on Cube programmer l but can't connect my device in their as well. I have Checked the hardware connections and supplies they are fine plus I am also seeing the GPIO toggle.I want to erase the chip firmware so I can start new on my PCB where I can keep the debug pins settings as default.

Hello STM Community,I am currently using STM32CubeIDE and would like to log the data that I observe in the Live Watch window during debugging. Is there a built-in way to export or log this data for further analysis (e.g., to a CSV or text file)? If not, are there any recommended methods or workarounds to achieve this?Any guidance or suggestions would be greatly appreciated!Thank You.

I was trying to run a code in STM32CubeIDE v1.19.0. I have connected the MCU to my laptop via ST-LINK/V2 but when I tried running the program or updating the firmware on the ST-LINK/V2 I get the respective error messages:I am new to STM32 development.

Hi, Do you know the meaning of this icon (I think Tulip)?Thanks.

 in cube mx (cube ide version Version: 1.19.0)   i can select i2c3 for STM32F411CEU6bun can someone verity that this chip in ufqfpn48 support i2c3?? 

    Dear forum members,I work on a project that repeatedly reads 3692 pixel intensity values from a linear CCD pixel-array. The readout process and export of the data via USB is working fine.Now I want to enhance the application by multiplying each pixel value with its specific correction factor to compensate for the individual sensitivity. I struggle to find the right method to import the correction values from a text-file.At first I tried to add a user include file that assigns the float values (in the range 0.90 to 1.10) to the array 'g_PixFactor' that is declared in the 'main.c' file. This approach produces errors like "re-definition of array 'g_PixFactor' ". I also tried to do the declaration and the assignment of the values in the include file, which gave other complaints. My questions are:   - Is the concept of importing values by an include file a workable method to solve my challenge?    - Can a more experienced forum member provide

When I copy a project within the IDE, it doesn't update the file references and the IOC file doesn't open. Can we have this fixed asap please?
