I've noticed a behavior with MX25UM5124G_STM32U5x9K-DK External loader over the past 2 years that I feel is a bug. I think the bug lies within the sectorwise erase of the MX25UM5124G_STM32U5x9K-DK External loader fw. If you flash a bin to external flash using the external loader with "erase before programming" enable , there is near 100% likelihood the verification step will fail. I believe this caused by the sectorwise erase not working as intended. The work around has been to do full chip erase on external flash then attempt the flash again. This will succeed almost every time. The behavior that led me to suspect the issue lies within the external loader is when I wrote a proprietary external flasher onboard the stm32. It uses sectorwise erase and has high reliability. This proves to me that flash chip and flash driver on the STM32 are working as intended. Note: We use this proprietary flasher for customer flashing updates but still use Cubeprogrammer for developm

Hello,Due to limitations with the STM32WBA's silicon & Bluetooth stack we've had to significantly re-engineer our hardware and add an external Bluetooth chip. As part of this, we updated our SAI blocks so that one block is transmit and one is receive, and moved our PDM microphones to a SPI bus.Since we have two PDM microphones, we've followed AN5027 "Interfacing PDM Digital Microphones":In our setup, we have SPI2 SCK (mapped to PB10) connected to PA1, and connected PA9 to the DMIC_CLK line. Our plan has been to map PA1 (input) -> TIM17_CH1, which then triggers (via ITR8) TIM3_CH2 which is mapped to PA9 (output).However, I'm struggling to set up the signals properly. I am able to configure TIM17_CH1 so that I can count SPI2_SCK. However, I am unable to trigger TIM3 to count at all.I've attached my example project for the NUCLEO-WBA65RI board.Any insight on this issue?Thank you,Jonathan

STM32CubeIDE is creating a new folder inside ".stm32cubeide\.jxbrowser-7.41.4" everytime STM32CubeIDE launches.It would be nice if the application cleaned up its junk, at least deleting old profile subfolders, as each one eats up 75MB.I just manually deleted over 75 of them dating back to October. 

hi i re-downloaded STM32 Cube IDE but i cannot find <create STM32 Project> I downloaded this sw over and over but nothing changed :(please help me with this 

Hello,I searched on Google but I don't know if anyone has encountered this problem before. As we know, CubeMx and Cube IDE were recently released as two separate programs. I think this error might be related to that.The error is this: I open a project I created in CubeMx in the IDE and upload it to the chip; there's no problem up to this point. However, whenever I make an update in CubeMx, the entire update isn't reflected in the IDE (or rather, in main.c). If there were no updates at all, I would look for the problem elsewhere, but some of the configuration settings are transferred to the IDE while others are not. The most recent example I experienced was that changes to the ARR and Prescaler registers of the TIMER module were transferred to the IDE, but the changes to the PWM (CCR1) register remained the same. In this case, I had to manually change the relevant value in main.c (and it was quite difficult to notice).Look, the main problem here is that we developers ultimately trust ST

Hello guys. I'm currently trying to use the dsp libraries of the cmsis pack with no success.My device is a WBA55CG nucleo board and the version of my ide is 1.19. I tried to download the cmsis package manually, by selecting embedded software package maneger and then from local/url and successfully installed the packages. (CMSIS 5.9). I enabled core and selected CMSIS from source and dsp. I enabled dsp and core on mx configuration->middleware and hit generate. I tried to inlcuded the arm_math lib on my program to see if the installation was successful and if cube could build my program..... aaaand all hell broke loose.../Middlewares/Third_Party/ARM_CMSIS/Source/SVMFunctions/SVMFunctions.c:29:10: fatal error: arm_svm_linear_init_f32.c: No such file or directory 29 | #include "arm_svm_linear_init_f32.c" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. ../Middlewares/Third_Party/ARM_CMSIS/Source/TransformFunctions/TransformFunctions.c:29:10: fatal error: arm_bitreversal.c: N

When I used the MMT tool in STM32CubeMX to configure a 256MB NAND FLASH based on FMC, an error appeared. I am using the STM32H743IIT6 chip and have configured NAND FLASH in the FMC. I want to know how to solve this problem. 

Yes I should have taken a backup - but modern software must always have build-in backup solution so you do not corrupt your own files. Ask chatgpt if you need the code. I used 2 days to make this project, luckily I have the main.c so I can copy names from this.  I am on Linux Mint version 22.2 with STM32CubeMX version 6.16.1 and Visual Studio Code Version: 1.107.1.The fault was in STM32CubeMX, that did not save correctly. During my work I experienced the software closing without saying a word on the error, especially in the ADC1 setup. But every time I could just start it again, but not this time:-(Attached you find the surviving part of the IOC file.Thank you for listening to my disaster. Best regards   

Hi,when generating a project for the STM32G484 using STM32CubeMX (6.16.1) and create a project and code for this. I cannot seem to get it to build (and/or debug) in STM32CubeIDE (2.0.0).What am I missing here?Thanks,ErX.

In my STM32CubeIDE, the labels and tabs are displaying as garbled text (random characters). This makes it difficult to navigate and use the IDE.My current development environment is as follows.STM32CubeMX v6.7.0, STM32CubeIDE    Version: 1.15.1     Windows 10 19044.1766    JAVA_VERSION="18.0.2.1"How to solve these garbled code problems? I have reinstalled this IED many times。

Been working on this for a few weeks now, I'm losing my mind. In STM32CubeIDE, only time I can get anywhere is in hardware reset, and there it times out. In STM32CubeProgrammer, it does connect. It can read the MCU name, flash size, all of that. All addresses read 00000000. However, I can't write in the programmer, and I just can't figure out why. Write to memory failed. Failed to erase data. Failed to download data. This is my first time doing something like this, so maybe I'm missing something. But nothing I've looked up has helped.

Hi, I have a problem with my CubeIDE installation that is that I cannot create a stm32 project(the option that integrates with CubeMX) I can only create the followingI've installed it from the shell script from the generic Linux download, I'm using arch Linux(btw).I've reinstalled it at least 3 times now, also went to Help -> Install New Software, used this site: And installed everything down the STM32CubeIDE section. 

 We are using the STM32N657Z0H3Q (142-pin TFBGA package).CSI behavior in STM32CubeMX is inconsistent across versions:In older CubeMX versions(1.64), CSI lanes (CSI_D0P/N, CSI_D1P/N, CSI_CKP/CKN, CSI_REXT, etc.) are displayed in the Pinout view, but these signals are not actually assignable to physical pins. They appear as virtual pins only.In newer CubeMX versions(1.65), CSI is still listed in the peripheral view, but no CSI lane pins are shown at all. In case, the generated .ioc file contains only virtual signals:VP_CSI_VS_CSI.Mode=CSI VP_CSI_VS_CSI.Signal=CSI_VS_CSI VP_DCMIPP_CSI.Mode=SerialInterface VP_DCMIPP_CSI.Signal=DCMIPP_CSIOn hardware, when connecting a CSI-2 camera, the following is observed:DCMIPP and CSI registers initialize correctly,no LP-to-HS transition on the supposed CSI pins,ClkAct remains at 0,CSI interrupts never trigger.This behavior strongly suggests that the CSI-2 D-PHY pins are not bonded out on the STM32N657Z0H3Q package, even though CubeMX and the

I'm planning on moving from STM32F103 for more speed, so in advance of getting a board I thought I would try building an app for the STM32G431... so I found an small example project online that was using an OpAmp feature.Having got that compiled ok in STM32CubeIDE I backported my app source code into the project (which went ok), but compiling it was missing some definitions for HAL UART structures.Looking at "Drivers/STM32G4xx_HAL_Driver" in my original project and comparing it with "Drivers/STM32G4xx_HAL_Driver" in the new project I see that its missing some files like "stm32g4xx_hal_uart.h". Is it possible to force STM32CubeIDE to regenerate the Drivers subfolder from scratch?I always find switching a STM32CubeIDE project between different MCUs a harder job than it should be, e.g. it would be nice if there was a combo box listing MCUs in the project properties.  

Hi and happy new year... I'm a complete beginner, and I'm facing a major problem.I've tried creating a new project in CubeID for an STM32F401CEUx.But the project "STM32 Project" doesn't appear in the list of new projects.The closest thing I find is one called "STM32CubeIDE Empty Project," and when I create a project using this template, the initial image of the chip where I configure the pins doesn't appear, and the IoT file isn't in the project tree either.Why could this be? 

Hi,I am working with the STM32N6570-DK board. Initially, I am using the GPIO_IOToggle example project to verify the basic board functionality.I configured the hardware using STM32CubeMX v6.16 and generated the project using the STM32CubeIDE toolchain. The project was built successfully using STM32CubeIDE v2.0.0.When I run the project in debug mode from CubeIDE, the LED toggles correctly.However, the device does not boot when I flash the binary manually using STM32CubeProgrammer v2.21.0. Signing and Flashing DetailsI am using the following command to sign the output binary generated by CubeIDE:STM32_SigningTool_CLI -bin <path to fsbl project.bin file> -nk -t fsbl -hv 2.3 \-o <path to fsbl project-trusted.bin file> \-dump <path to fsbl project-trusted.bin file> -align After generating the trusted binary, I flash it at address 0x70000000 using STM32CubeProgrammer.Boot ConfigurationBOOT0 switch: position 1–2BOOT1 switch: position 1–3After flashing the trusted bi

Hello,I'm facing very strange issues with STM32CubeIDE 2.0.0 under Linux Debian Trixie/Forky.I'm running Kernel 6.17.11+deb14-amd64 with Plasma 6.5.4, KDE Framework 6.20.0 and QT version 6.9.2 in Wayland.First issue is with debugger. I can start the firmware in debugging mode, runs but after few "Step Into" and "Step Over" commands the debugger is getting stuck. I doesn't take any commands anymore.If I use "Restart" or "Terminate" or "Terminate and Relaunch" is starting again and again I can use few times "Step Into" and "Step Over" Second issue is with windows ordering after using for a while STM32CubeIDE: it breaks completely the windows orders under Plasma and the only solution is to logout and login back and restart all apps.I didn't get this issue with any other apps, except STM32CubeIDE.

Hello ST Community,I am writing to report a serious regression in STM32CubeMX 6.16.0 running on Arch Linux (KDE Plasma) with a 1920x1080 resolution.Environment:OS: Arch Linux (Rolling)Java: OpenJDK 25Desktop: KDE Plasma (Wayland/X11)Screen Resolution: 1920x1080The Regression (Comparison):1. STM32CubeMX 6.15.0 (Previous Version):Status: Works perfectly out-of-the-box.Details: I did not need to modify any configuration files or set any environment variables. The application launched correctly, the UI was usable, and the window could be resized and maximized without issues.2. STM32CubeMX 6.16.0 (Current Version):Status: Unusable / Broken.Details:The default UI rendering has issues (fonts are tiny or behavior is inconsistent).When trying to fix it using standard scaling methods (e.g., _JAVA_OPTIONS="-Dsun.java2d.uiScale=2" or GDK_SCALE=2), the window management breaks.The window refuses to maximize, enter full screen, or resize properly. It seems internal window constraints have been chang

An intermittant bug... (as it happens it doesn't occur as I am reporting this issue).Open up a STM32CubeIDE project.Navigate to a project Source Folder, e.g. XYX...Core...SrcHighlight a source file, e.g. "main.c",right-click "Copy", right-click "Paste". Click "Ok" to the suggested filename "main2.c".Double-click "main2.c" to edit it, You can't cut or modify any text in the file, nor type in any new text.Close STM32CubeIDE and launch it again... the file is now editable.The bug appears perhaps 2% of the time, not a deal breaker but a bit annoying.  

I created a support ticket for this issue but haven't heard back yet, but I wondered if anyone else has seen this issue before. I have been having an issue with my STLINK-V3MINIE for some time now. When I set and hit a breakpoint, the program will often not start again no matter what I do. I am using arm-none-eabi-gdb with OpenOCD to debug a STM32H750, and will set a breakpoint or watchpoint in my code, and once it is hit, I am not able to get the target to continue again using "continue" or "step" commands in gdb. Even after deleting the breakpoint, the issue will remain and the only way to get the target to respond normally again is to reset the program with "monitor reset halt". The image I attached shows hitting a breakpoint, deleting the breakpoint, then not being able to continue I tried upgrading the firmware on my STLINK-V3MINIE, this did not fix it. It is an official STLINK-V3MINIE that I bought from ST, not a clone.Things that I tried that did not work as advised by
