Dear STM32 Support Team,I am trying to create a new project in STM32CubeIDE, but I encounter a few issues. First, I cannot select the "STM32Cube" option under the Targeted Project Type section when starting a new project.To work around this, I tried generating code through STM32CubeMX after completing my .ioc configurations. While the code is transferred to STM32CubeIDE, many essential files are missing, and the project does not build or run properly.Additionally, STM32CubeIDE displays an error message saying: "Fix the highlighted errors and try again." However, I cannot identify what these errors refer to, as nothing is clearly highlighted.I am using the latest version of STM32CubeIDE, and I have already uninstalled and reinstalled the software, but the problem still persists.Could you please help me resolve this issue?Best regards,Emre MERCAN

 I’m currently developing a template to help developers debug code located at address 0x8011000 using VSCode.So far, I haven’t had any success getting the debugger to work properly.The .elf file itself is fine, when I flash it using STM32CubeProgrammer and enable "Run after programming", the code executes as expected.I’ve tried multiple solutions, including suggestions from ChatGPT, but nothing has worked yet. 

Hi guys,I'm new to STM32. I tried creating new project, chose my board, but the option of targeted project type is always empty. I read few posts here that talked about download version 1.19.0. I did it and still the same. don't know what to do.I appereciate if you could help me.thanks,Roi

Hello everyoneSince yesterday  when I try to create a new project in STM32CubeIDE, the CubeMX configuration window doesn't appear, and the ioc file is not being generatedHas anyone else experienced this issueCan someone help me understand how to fix it

Dear STMicroelectronics Support Team,I am facing an issue with STM32CubeIDE version 1.19.0 while trying to create a new STM32 project.In the project creation wizard, the “STM32Cube” option under “Targeted Project Type” is disabled (grayed out), and only the “Empty” option is selectable. This persists even after performing the following steps:1. Installed the required STM32 firmware package using “Manage Embedded Software Packages”2. Confirmed that the selected MCU is supported by the installed firmware3. Verified firmware repository path in Preferences4. Deleted .metadata and .stm32cubemx directories to reset the configuration5. Tried different MCUs (e.g., STM32F103C8Tx and STM32H750VBTx) to rule out unsupported device issuesDespite all these steps, the STM32Cube option remains disabled, preventing me from generating CubeMX-based initialization code through the IDE.Could you please investigate this issue or advise on any specific steps needed to restore proper functionality?Thank you f

I have recently updated my Cube IDE to v1.19.0 to resolve the problem of Empty Project creation. The problem was resolved. However, after one week now the problem is again there.

Hello STM community,I'm experiencing a UI/UX issue with STM32CubeIDE on my Linux system and would appreciate any insight or workarounds.My setup:Distro: Arch LinuxKDE Plasma: 6.4.3KDE Frameworks: 6.16.0Qt Version: 6.9.1Kernel: 6.12.39-1-lts (64-bit)Graphics Platform: WaylandMonitor: 4K with 150% scalingCPU: AMD Ryzen 7 3800XGPU: AMD Radeon RX 6600Memory: 16 GiBMotherboard: Gigabyte B450 AORUS PROI installed STM32CubeIDE 1.19.0 using the official generic Linux installer.To improve compatibility, I’m using a launcher script (stm32cubeide_wayland) like this: #!/bin/bash basedir=$(dirname "$BASH_SOURCE") export GDK_BACKEND=x11 export WEBKIT_DISABLE_COMPOSITING_MODE=1 "$basedir"/stm32cubeide "$@" This runs CubeIDE under X11, which allows STM32 project creation (CubeMX launches correctly), but the interface is blurry and not crisp on my HiDPI 4K screen.If I instead use:export GDK_BACKEND=wayland...the UI becomes sharp and scales properly (as expected), but CubeMX fails to lau

hi i use STM32cubeMX to generate project files in STM32cubeIDE, and hope use some bsp function(like BSP_XSPI_NOR_Init) in this project, but no matter how i try, i can not find any bsp function in it.who knows to solve this problem?(Now I have to manually handle this issue  by copy this function from other .c,and this method is very inconvenient )thanks!!!

 Hello, everyone.There is an issue related to USART3 DMA Receive of STM32F407.I'd like to use 500 bytes of USART3 DMA Receive.I wrote 500 bytes on UART Sender, but USART3 DMA Receive Callback is not working.I checked UART_FLAG_IDLE because I wanted to know why.When I checked IDLE Interrupt, it reads twice, 48 bytes each, and it doesn't read anymore.

Hi,I'm encountering an issue while trying to install an SFI using STM32_Programmer_CLI within a GitLab pipeline.Context:I'm using a GitLab runner with executor = shell (cmd), so the commands are executed directly on the PC where the microcontroller is physically connected.I'm executing the following command:STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -sfi %SFI% %HSM_LICENSE% -rsse enc_signed_RSSe_sfi_U5_2M.bin %SFI% and %HSM_LICENSE% refer to the corresponding .sfi file and HSM license.

I've written an external loader for a flash memory chip.  I'm able to program the flash chip using my external loader with STM32CubeProgrammer v2.19.0, but when I try to use my external loader with v2.20.0 it doesn't work. I've attached logs from both a good run with v2.19.0 and a bad run with v2.20.0.  I don't know how to debug this, because I naturally don't have access to the source code of the STM32CubeProgrammer CLI tool. Have there been any changes to the requirements of an external loader as of v2.20.0? Alternatively, can I somehow downgrade the STM32CubeProgrammer version that STM32CubeIDE uses? I'd really like to use the most current tools, but right now I'm stuck...

Hello,I am currently working with STM32 Cube IDEVersion: 1.18.1Build: 24813_20250409_2138 (UTC) When I try to create a new project I select the processor and click next. Then the setup dialog appears (as usual).But in the targeted device selection the STM32Cube IDE project is not selectable:  Consequently I get no .ioc file after creating the project. Things I already tried:1. Restart IDE2. UpdateHelp > Manage Embedded Software PackagesUnder STM32Cube MCU Packages, install the firmware for your MCU series (e.g., STM32F4).3. restart IDE with -clean optionIn a bash I usedSTM32CubeIDE -clean Nothing helped. What can I do? regardsAlexander

Hello ST Community,I’m facing a persistent issue while creating a new STM32 project using STM32CubeIDE, and I need some technical support.Problem Description: version 1.19When I create a new project, the .ioc file is not generated.The "Target IDE / Toolchain" field shows as empty (not STM32CubeIDE).Because of this, the project does not build or open properly in the IDE.I have selected the correct microcontroller, like STM32F103C8T6, but the problem still occurs.Steps I followed:Opened STM32CubeIDEFile → New → STM32 ProjectSelected correct MCUGave a valid project nameBut the project doesn’t target STM32CubeIDE and no .ioc file is createdWhat I tried:I updated STM32CubeIDE to the latest version, but the issue still exists.I tried restarting the IDE and creating the project multiple timesI checked toolchain settings, but nothing seems to be fixing itWhat I need help with:Why is STM32CubeIDE not generating the .ioc file or setting itself as the target toolchain?Is there any way to fix or c

hello everyone , When I create a new project in STM32CubeIDE (version: 1.17.0), the .ioc configuration file is not generated in the project directory. Here’s what I’ve tried:Project Type:Created via File > New > STM32 Project (using the STM32 Project Wizard).Selected my MCU/board .Expected Behavior:A .ioc file should appear in the project root after setup (enabling peripheral/clock configuration).Actual Result:Only standard project files (e.g., Core/, Drivers/, .project) are generated. No .ioc file exists.I cannot open/configure the project in STM32CubeMX.

Hi,I am completely new to the st family of microcontrollers and an amateur.Before I had my setup running with an esp32 but I just missed the performance I need so I switched. I tried to configure within cubemx and import into platformio for furher developmentI want to connect three audiodevices using i2s (2 receive, 1 send) with the stm generating the necessary clocks for it and I am really struggleing to do so. I want to run 48 kHz and was wondering if you have any ideas how to set it up properly. Thanks for helping

Dear STMicroelectronics Support,I am currently using STM32CubeIDE version 1.16.0 and facing an issue during project creation. The STM32Cube project option remains greyed out, regardless of the MCU or board selected (e.g., STM32L476RGT6, STM32H747I-DISCO).Even if I proceed with the "Empty" project type, the .ioc file is not generated, and the CubeMX interface does not open.I have already tried the following steps:-Verified that STM32CubeMX is installed and integrated-Switched to a new workspace-Fully uninstalled and reinstalled STM32CubeIDE v1.16.0Despite these efforts, the issue still persists.I have attached an image below for your reference.Please advise on how to resolve this issue or provide guidance on any known fixes.Thank you for your support.Best regards,Sai Ganesh CSZettaone Technologies
