Hello,i am working with the STM32F401RE board along with the IHM02A1 expansion board. I am using the X-CUBE-SPN2 package.I am working with a predefined project from X-CUBE-SPN2 and modifying it according to my requirements. I am defining all the GPIO pins, using some as input and some as output.However, I am facing a problem with GPIO pins PA13 and PA14. These pins are used for the debugger by default. I do not want to use the debugger and instead want to use these pins as input/output.I want to know how to disable the debug function for these pins and directly flash the program to the board. I have also tried using the “green icon” menu to flash, but it is not working.This is quite urgent. I would really appreciate your guidance on how to resolve this issue.Thank you so much in advance.

I'm sure it's something silly and I can't believe I'm the only person who has seen this message but searching this site doesn't yield any clues. Can someone point me to what I am setting up wrong, presumably in the Debug Configuration menu ?

Hello,Is it possible to show indent guides (vertical dotted lines) (for example, see Figure 1 below from the Visual Studio 2022) of the STM32CubeIDE code editor?    Figure 1. 

I'm trying to figure out why the value 4.2 is returned as -2 when passed as a function argument. Could you please also provide a solution? The MCU is an STM32F302VET.

Hello folks,I am new to STM32 and have been using it (STM32H7A3ZIQ) for a while, everything was fine with download and debugging codes until a week ago when STM32CubeIDE suddenly has stopped launching the debug session. An error msg -failed to start GDB server (see attached) pops out whenever I want to debug codes, I have been trying to resolve this very problem for the past week by following other people's solutions on Youtube, but all my attempts were in vain. In addition, I installed different ST-Link programs provided by ST such that ST-Link server (Utility), STSW 004, 007, and 009. But even by doing so, I couldn't resolve this matter and no device found remains.NB: Even after having updated my device (V3.J8.M3) by using ST-Link 007, STM32CubeIDE doesn't recognise it at all (no device found on target). ST-Link utility also cannot connect to the target​I hope someone could help me to get back coding. I look forward to hearing your expert thoughts on how to resolve it.BR,AD

Hii,I am using STM32H745XIX6 microcontroller for our custom boards and also enabling the Touch GFX in it, we are doing dual core debugging, and the both the cores got activated and working fine after changing some settings in debug configurations of both the cores.To check the dual core debugging, I have changed the debug configurations to "Connect under Reset" and selected "Halt all cores" in 1st Core (CM7) and changed the debug configurations to "None" in 2nd Core (CM4).To add the images in the external SDRAM, I have added the external flash section in the flash linker script. Images that I have added in the Touch GFX are storing in the external SDRAM Memory. Then, I am getting problem in the debugging. What might be the issue?If I've changed the debug configurations to "None" in 1st Core (CM7) then the debugging after changing the linker file is fine. But only 1st Core is going into debug.Both the dual core debugging and when storing the Images in the external SDRAM Memory afte

Hello,I've got two NUCLEO-STM32H7S3L8 boards and started playing around with those. I created a project in STM32CubeIDE and used the standard template for the board with the generated example data. STM32CubeMX generated the "Appli," "Boot," and "ExtMemLoader" projects, but they seem to have some errors. Here's what I found so far:"Appli"-Project:This line of generated code: #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */This led to this compiling error:../Core/Src/eth.c:36:58: error: missing '(' in expression36 | #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */| ^../Core/Src/eth.c: In function 'MX_ETH_Init':../Core/Src/eth.c:73:22: error: 'DMATxDscrTab' undeclared (first use in this function)73 | heth.Init.TxDesc = DMATxDscrTab;| ^~~~~~~~~~~~../Core/Src/eth.c:73:22: note: each undeclared identifier is reported only once for each function it appears in../Core/Src/eth.c:74:22: error: 'DMARxDscrTab' undeclared (first use

I wrote this maybe it helps somebody.My software system is running on ubuntu 24-04 which crashed when I attemped to upgrade.I found the IOC would not render at all.Long story short I could create an MX project and the IOC was created correctly but when I transitioned to the cube IDE the IOC would not render.I found this! I got java lang issues and eclipse editor issues than looking in more detail Iistening on port 41 which seemed to get no response. The rendering hung with no response - is the eclipse https site there?This I then moved to a virtual machine so I could keep resetting after a crash.Well I turned off the network so it now had no network connection and I got a message about the keeping it online for a better experience. Well in preferences there is also an offline checkbox - enable that and now my IOC's render fine.This is Cube IDE 1.19.0 and Cube MX 6-15-0 runing on Ubuntu 24-04.Note also:- had to "sudo apt install python3-tk" to install a module missing from python.&

 CubeMX didn’t configure PD13 (TIM4_CH2, AF2) for PWM on STM32G474VET — manual GPIO init requiredMCU/Package: STM32G474VET (LQFP100)Tooling: STM32CubeMX / STM32CubeIDE (version:Version: 1.16.0Build: 21983_20240628_1741 (UTC))Project type: HAL, PWM on TIM4_CH2Clocking: System clock 168 MHz (TIM4 clock effectively 168 MHz), PSC=3, ARR=999 → ~42 kHz; CCR2=500 (50%)SummaryEnabling TIM4 CH2 PWM on PD13 in CubeMX generated code that started the timer, but no waveform appeared on PD13. The generated project did not set PD13 to Alternate Function 2 (TIM4). Manually adding the GPIO init for PD13 (AF2) fixed it immediately.Again I am finding alternate pins not supported (actually more like ignored)  by STM32IDE Cube. The previous one was CANFD3 on alternate pins.Steps to reproduceCreate a new CubeMX project for STM32G474VETx.Configure TIM4 → Channel 2 as PWM Generation CH2.Assign PD13 as the output pin for CH2.Set clocking for ~168 MHz system.

I've just bought a NUCLEO-F103RB board, and installed STM32CubeIDE 1.19.0.I've gone through the following steps:Made a simple application (File->New->STM32 Project)PA5 configured as a GPIO output (for the green LED LD2), and PC13 as a GPIO input (for the blue button B1)The c code is a simple "if button pressed then turn on LED, otherwise turn LED off". All works as expected.I then double clicked on the ioc file to use the GUI to edit the pin configuration, and under Pinout & Configuration I enabled USART2 (changing it from mode Disable to Asynchronous). All other parameters were left untouched.After using the cog icon (Device Configuration Tool Code Generation) I rebuilt the project and used Run As to download it to the board. As usual the console in the IDE reports "Download in Progress, File download complete, Verifying..., Download verified successfully", but then repeatedly prints "Target is not responding, retrying...". I assumed I'd made a mistake in enabling this

Does anyone have experience with integrating hierarchical state machines (C-code) with a STM32CubeIDE project?For example, the QP/C software by Quantum Leaps generates state machine C-code based on a graphical modeling tool. If the state machine diagram changes the C-code is re-generated: https://www.state-machine.com/qpc/index.htmlHow can this capability be integrated with the STM32CubeIDE?In particular, if the state machine code is updated, how is the project source updated?Also, if the STM32CubeMX files (.ioc) is updated and the project source is re-generated, how can the state machine code be protected? (I assume the IDE's USER CODE section can be used for that...)Any feedback will be appreciated. Thank you!

Hi all, I have an STM32H743 project that I've been working on. I've worked on a fair amount of projects in STM32CubeIDE in the past, but now I have a problem I haven't encountered before: the linker is putting my .bss section in flash as well as RAM. I'm not sure why an uninitialized section would be placed in flash... I've attached the output from the build analyzer as well as my linker script. The script is almost the default, except that I've added D2/D3 RAM and have moved stack & heap to DTCM. I've used very similar scripts in other projects and BSS ends up only in RAM in those projects.Can anyone find what I'm doing wrong? Thanks! 

Hello, I saw a thread titled Your Input Matters: How Do You Use STM32Cube Examples?And I tried to enter to the examples selector of CubeIde (I never tried before).When I open the selector, my computer takes several minutes with the cpu fan at highest speed. After this, I tried to select a board to reduce posibilities, and happened the same, but I had a memory full error.The only way to continue is to kill CubeIde. It's impossible to close it safely.But now CubeIde does not start. It ask me the workspace, and shows the picture of screenshot I attached.If I select a different workspace, it works. And now, my questions are...Can I restore my workspace? Seems all project files are present.Do I need more memory?My system is:Linux mint 21.3, Linux 5.15.0-153Intel i7-8700K @3.7GHz (6 core, 12 threads)16GB RAMCubeIde 1.15.0 Thanks for your reply    

Hello everyone,I want to make a usb connection using USB_OTG_FS_DP and USB_OTG_FS_DM pins on the STM32U575 board. When I tried it with the examples found on the internet, it didn't work. When I tried the same method on the STM32F401 board, it was enough to select only USB_OTG_FS -> Device Only and Middleware -> USB_DEVICE -> virtual com port. What basic settings do I need to make to see my STM32U575 board as a virtual com port on the computer? I'm not very experienced in this. Thank you in advance for your help. Also, when I use the ux_device_cdc_acm example in CubeIDE, it does not appear as a virtual com port.

Hi !I have troubles with using cmake and STM32CubeIDE on my laptop: I am trying to compile a project, and when I use the build (hammer) button, it errors out with this:**** CMake Configure of configuration Debug for project gamma_focal ****C:\Program Files\CMake\bin\cmake.exe -S . -B build/Debug -GUnix Makefiles -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ONCannot run program: "cmake": Ensure CMake is installed and available from the system PATH. However, when I type the command in my terminal, it works nicely (I have to insert quotes to format the shell command correctly). So Cmake is on my path. I verified it was inside both user and system level env variables. It is also inside the Pathenvironment variables inside Properties -> C/C++ Build -> Environment. I believe this is likely a bug, the same project on my co-worker computer's compiles OK. I am using STM32CubeIDE version 1.18.0, and it also didn't work when switching to version 1.18.1. I'm on a window

NUCLEO F411RE, CubeIDEAs a learning exercise I'm trying to generate 100Hz cosine wave & then eventually do a DFT on it but I'm getting some odd results from the cos function using code below... #include "arm_math.h" #define NUM_SAMP 100 #define SIGNAL_FREQ 100.0 #define SAMPLING_FREQ 1000 static void fpu_enable(void); typedef struct { float real; float imag; }complex_number; complex_number samples[NUM_SAMP]; main() { fpu_enable(); /* Generate a test signal 100Hz */ for(int n = 0; n < NUM_SAMP; n++ ) { samples[n].real = cos(2 * PI* SIGNAL_FREQ * n / SAMPLING_FREQ); samples[n].imag = 0.0; } } static void fpu_enable(void) { SCB->CPACR |= ((3UL << 10 * 2) | (3UL << 11 * 2)); }  When I check the values in samples in the debugger....I was expecting a value of 1 for the first entry and then subsequent values in the interval [-1, 1]Is this a formatting issue in Cube's debugger or am I missing something obvious here? 

I'm developing a LoRaWAN device using STM32CubeIDE with the LoRaWAN stack (SubGHz_Phy and LoRaMac) on an STM32WLE5JCI6 microcontroller. When I try to enable the AS923 region, I'm consistently getting the debug error DEBUG: Region not defined in MW, which prevents the stack from initializing correctly.I've taken the following steps to troubleshoot the issue:Project Settings: I've confirmed that -DREGION_AS923 is added to the compiler's defined symbols and that other region-specific files, like RegionAU915.c, are excluded from the build.Code Modification: I changed the switch statements in Region.c to use direct function calls with case LORAMAC_REGION_AS923: instead of macros like AS923_...(). This resolved the compiler warnings, but the runtime error persists.Based on the logs, LmHandlerInit attempts to initialize with region 9, so the value seems to be passed correctly. I suspect the issue is that the compiler is not correctly linking the functions from RegionAS923.c with the calls in

I am using the STM32F302R8Tx microcontroller. I usually work in debug mode. One day, I decided to use release mode and faced a problem.

Using Stm32CubeIDE 1.3.0...When I Copy and Paste a project in the Project Explorer (and name differently), it does copy the project. I also renamed the CubeMX IOC file to match the new project name. Then I did a Clean and a new Build. However, when I go to Debug, I get a number.To verify that the new project is using the new project paths I do a "Close" on the first project, then rename the old project in Windows Explorer.Builds fine, but when debugging it is complains that it can't find source files. It is still looking for the source files in the original project.... I changed the source lookup path in the Debug Configurations > Source to look in this project, and it still cannot find the files.And when checking if there are any files in the new project's Debug folders, they are indeed empty. Does anyone have an idea how to fix this?

On (up-to-date) Windows10-64 machine, I just downloaded and installed (for first time) STM32CubeIDE.  (Up to date Norton) reports the following "High Threat". Details below.  The last reference I can find by googling this error goes back to 2020, and was apparently fixed.Before I click the "make exception" option (or just delete the installer), I want to make sure a true virus hasn't somehow snuck into the current release. -bob ____________________________DetailsThreat name: IDP.GenericThreat type: Miscellaneous - This is an app that you may have unknowingly installed and that may harm your computer performance.Status: Threat detectedDetected by: Behavioral ProtectionOn PC from: 2/27/25, 10:02 AMLast Used: 4/8/25, 9:33 PMStartup Item: YesMany usersThousands of users in the Norton Community have used this file.MatureThis file was released a month ago.HighThe file risk is high.____________________________OriginLocation: local://*C:\Users\rober\Downloads\en.s

Hey all.As per tradition, my first post in this community will be a question.In the same way that I can run pre- and post-build commands that is run when I build a project in STM32cube, is it possible to run a post code generation command when I generate code from the .ioc file?- Moose

I am using a MacBook M1 Max (Sonoma 14.6.1) and STM32CubeIDE(1.16.0) with a STM32g0316-disco board.   Everything was working fine until, out of the blue, I started getting LibUSB errors when I tried to flash/debug my code.I tried a second identical dev board and new cables and every usb-c port on my Macbook and the error persists. I brought the machine up in safe mode and the error is still there.  Here is the Error message from the IDE.libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive accessDevice connect error Error in initializing ST-LINK device.Reason: libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive accesslibusb: info [darwin_claim_interface] no interface found; setting configuration: 1libusb: error [darwin_claim_interface] could not set configurationFailed to connect to device.

Before the STM32CubeIDE had serious issues with the live expressions during debug, with variables showing random values and signs when they were unsigned (the issues are various years old now https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-1-18-0-released/m-p/778624#M34678) After updating to STM32CubeIDE Version: 1.18.0 Build: 24413_20250227_1633 (UTC) the live expressions completely broke All the variables now show 0 and they won't vary As you can see from the screenshot, hovering while on breakpoint shows the correct value. On the top right, all the values are 0 in the live expressions tabThat's pretty bad considering, trying to migrate to VSCode for being able to debug, gives another sort of issue, acknowledge by ST itself https://community.st.com/t5/stm32-vscode-extension-mcus/stm32-vs-code-extension-no-compiler-found-in-cache-file/m-p/781619#M640 What happened to this company lately...?
