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

I see it's been a while but I ran into this today. Apparently system_stm32g4xx.c that is automatically generated by STM32MX no longer sets SCB->VTOR unless you define USER_VECT_TAB_ADDRESS in that file. When programming that doesn't cause an issue but it does stop you from debugging if interrupts are enabled. I wasted half a day of my life on this today. I don't know what benefit ST thought we'd get by changing this but breaking debugging for their customers they probably wasted a lot of the world's time. An awful lot of people were used to being able to generate code and use the debugger without modifying an autogenerated file they'd never needed to modify before. Edit: moved from HAL_Delay() --> SysTick_Handler never be called to a new thread.

Hello everyone, and thank you in advance for your kind assistance.We've noticed a discrepancy between the datasheet and STM32CubeProgrammer for the STM32U073RCT6 device.In the datasheet (DS14548 - Rev 2, page 45), the threshold specified for VBOR0 is 1.7 V.When connecting to the board with STM32CubeProgrammer v. 2.19.0, the GUI indicates that the minimum selectable value is 2.0 V (option bytes).Can you please confirm:If VBOR0 = 1.7 V, is this the guaranteed value (typ/min/max as indicated in the datasheet) for this OPN?If there is a known restriction with CubeProgrammer or ST-Link that prevents the selection of VBOR < 2.0 V for this device?If there is an errata/note that changes these values?Thank you all for your kind attention.

I am using an ST-link / V2 as the debugger and the microcontroller I am using is STM32l031k6u6. I am trying to debug and download a program into the microcontroller but I am facing this error. I have tried to debug and download using IAR embedded workbench as well but to no avail. I would be obliged if anyone can help me out. I did connect the VDD, GND, NRST, SWCLK, SWDIO pins correctly.   

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

We develop firmware on STM32H7R3L8HxH.STM32CubeIDE version is 1.19.0MxCube version is 6.15.0The problem is that code generator creates additional wrong include file for "regular" H7 MCUs:#include "stm32h7rsxx_hal.h" #include "stm32h7xx_hal.h"As this second file does not exist, compiler gives error:fatal error: stm32h7xx_hal.h: No such file or directoryIn application project it appears in main.hIn bootloader project the issue does not appear, but there is a blank line instead.In extmemloader project it appears in extmemloader_init.h Had same problem already STM32CubeIDE v1.18 and we have been manually fixing it (by removing bad include) so far, but it appears that it won't get fixed by itself so I report the issue now.

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 installed Manjaro Linux, downloaded STM32CubeMonitor from the official website, and then installed it via yay by replacing the package’s cached file with the official one:rm -rf .cache/yay/stm32cubemonitor/en.stm32cubemon-lin-v-1-10-0.zipmv stm32cubemon-lin-v-1-10-0.zip .cache/yay/stm32cubemonitor/en.stm32cubemon-lin-v-1-10-0.zipmakepkg -siWhen I launch stm32cubemonitor, I get the following error messages:29 Jul 09:49:09 - [info] Server now running at http://127.0.0.1:1880/29 Jul 09:49:09 - [warn] Encrypted credentials not found29 Jul 09:49:09 - [info] Waiting for missing types to be registered:29 Jul 09:49:09 - [info] - acquisition out29 Jul 09:49:09 - [info] - acquisition in 

Hello,I am new to FW/EE design for one of my board that has a STM32G0B1CEU6N. I got the board from our CM that has wifi modules and a battery connected to the PCB board which has the above mentioned STM.  What i would like to understand is how to communicate with the board for flashing the new FW/SW. The board has a 2X2 (pin header) that has the SWDIO, SWCLK, NRST and GND.  Can this pin be connected to ST-LINKV2 to talk via USB from WIndows. I also have STM32CUbeprogrammer installed. I tried connecting it the way as mentioned above but it does not detect. What could be the issue here?

When upgrading to versions 6.13 and 6.14, regenerating the project would force the file encoding to UTF-8, causing garbled Chinese comments. However, adding a line -Dfile.encoding=GBK in the STM32CubeMX.l4j.ini file under the installation folder could solve the problem. But after upgrading to version 6.15, this command seems to have become ineffective. Even if the system variable is added, the regenerated code will still be forced to UTF-8 encoding. Using UTF-8 is rather troublesome. Does anyone know how to change it to GBK encoding?

When I try to select which channel gets a watchdog, it only gives me one option on the pull down. Instead, if I want to change the channel, I have to unselect all the ADC channels and make sure that the watchdog intended channel is the first one selected. Is this normal? From the photo above, only one channel is always available in the pull down.

Dear STMicroelectronics Support Team, I hope this message finds you well. I would like to report a clock configuration issue encountered when working with TouchGFX and STM32CubeMX for the STM32F746G-DISCO board. When creating a project using TouchGFX and selecting the STM32F746G-DISCO board, everything works as expected initially. However, after opening the project in STM32CubeMX and enabling the SDMMC interface, the tool prompts to "Resolve clock issues." Upon accepting the proposed solution, CubeMX automatically modifies the clock configuration in a way that alters the LTDC (TFT LCD) pixel clock from its original value of 9.6 MHz to a different value. As a result, the display no longer renders correctly. After investigation, I realized that the auto-resolve feature in CubeMX does not preserve the required clock settings for the display, and instead prioritizes SDMMC configuration. To fix this, manual fine-tuning of the clock tree is required to ensure the LTD

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. 

when I use V6.14.1 everything goes well, bug when I update to V6.15,the same IOC file shows LTDC RGB565 confict with usart2, when I disabled usart2, re-enabled LTDC RGB565,LTDC_R1 pin come out but no R0,R2, it must be a bug here!

Hi. is any one facing issue like mine.  After updating STM32CUBEPROGRAMMER TO V2.20 external loader giving error at erasing external memory. when i download the code in controller having external qspi flash, it is showing error "failed to erase chip".  screenshot is attached. If i perform Full CHIP Erase. I am able to erase the chip. ever single sector is erased. but my code uses 111 sectors of external memory which is failing to ease. same issue is giving at cubeide 1.19.0. before updating everything was working. i upadated IDE and it failed to erase the chip. but my old cube programmer was doing job. when i updated cube programmer, it also stopped erasing external memory 111 sectors.

I'm developing an app on the demo board STM32U5A9J-DKI've created the project from TouchGFX 4.25.0 project STM32U5A9J-DK FreeRTOSIt perfectly works, compile and debug with both TouchGFX and CubeIDE 1.18.1I then opened the .ioc file of the project with Open CubeMX 6.14.1. It says the project was set up with 6.14.0 and FW_U5 V1.7.0, so I migrated it.I've updated the Software Packs from X-CUBE-FREERTOS 1.0.0 to 1.3.1. CubeMX says no issue found and upgraded.Then I generated the code. There, the new code rewrote the app_freertos.c file deleting the initialization of the TouchGFX task/* Definitions for defaultTask */ osThreadId_t defaultTaskHandle; const osThreadAttr_t defaultTask_attributes = { .name = "defaultTask", .priority = (osPriority_t) osPriorityNormal, .stack_size = 128 * 4 }; /* Definitions for GUI_Task */ osThreadId_t GUI_TaskHandle; const osThreadAttr_t GUI_Task_attributes = { .name = "GUI_Task", .priority = (osPriority_t) osPriorityNormal, .

Hi everyone,I’m still having an issue with my STM32F746G-Discovery board. I want to run the program using VSCode, but I’m encountering errors in my main.c file. Specifically, it can't find main.h, and as a result, the code isn’t running.I want to build and run the code directly in VSCode, but it’s not working as expected. Could it be that the compiler is misconfigured? I’m currently using the GCC compiler for C/C++.I also switched the toolchain in CubeMX to Makefile. After that, I installed CubeCLT and tried to run and build the code, but nothing happened. 

When I use CubeMX, the default language of my genereted code is C. I would like to develop in C++, as I can do in STM32CubeIDE. (I want to use VSCode to program)Is there any option to do this? I've tried just change the main.c to main.cpp, but it didn't work.(I'm a noob. So, if this questions is elementar, please, let me know likewise).
