    ☑️ Preparation for installation on Windows

    Done: 0 / 4

    1. Run the downloaded file st-stm32cubeide-1.14.0_windows-x86_64.exe (for 64-bit systems). If a warning appears SmartScreen, press Read more → Run anyway.

    2. In the installation wizard, select:

    • 📁 Installation folder (recommended C:\STM32CubeIDE\).
    • ✅ Components: leave a check mark on STM32CubeIDE And STM32CubeMX (if you need a code generator).
    • 🔌 Drivers: check the box Install ST-Link drivers (critical for working with development boards).

    3. After installation, restart your PC. Check for drivers in Device Manager (section Other devices must not contain unknown devices with an exclamation mark).

    Linux (Ubuntu/Debian)

    1. Unpack the archive st-stm32cubeide-1.14.0_linux-x86_64.tar.gz to home directory:

    tar -xvzf st-stm32cubeide-*.tar.gz -C ~/STM32/

    2. Run the installation script:

    cd ~/STM32/st-stm32cubeide-1.14.0/

    ./setup

    3. To work with ST-Link add a rule udev:

    sudo cp ~/STM32/st-stm32cubeide-1.14.0/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.linux64_1.0.0.202105311346/tools/udev/99-stlink-v*.rules /etc/udev/rules.d/

    sudo udevadm control --reload-rules
    

    sudo udevadm trigger

    💡

    If the IDE does not start after installation, check the folder permissions ~/STM32/ and execute chmod +x ~/STM32/st-stm32cubeide-1.14.0/stm32cubeide.

    macOS

    1. Open the downloaded file st-stm32cubeide-1.14.0_macos.dmg and drag the icon STM32CubeIDE to a folder Applications.

    2. When you launch it for the first time, macOS will block the application (error "STM32CubeIDE" cannot be opened because the developer cannot be verified). To enable execution:

    • Open System Settings → Privacy and Security.
    • Click Open anyway next to the warning about STM32CubeIDE.

    3. To work with ST-Link install the driver manually:

    brew install --cask stlink

    Solving common errors

    Even with correct installation, users encounter problems. Below is a list of common errors and how to resolve them.

    • 🔴 Error "Failed to launch JVM":

      Cause: Corrupt Java installation or version conflict. Solution:

      1. Delete the folder ~/STM32/st-stm32cubeide-*/jre.
      2. Download OpenJDK 11 and specify the path to it in the IDE launch settings.
  • 🔴 ST-Link is not detected:

    Check:

    • Connecting the board via USB (try a different port).
    • Availability of drivers in Device Manager (Windows) or command output lsusb (Linux).
    • No conflicts with other debuggers (for example, J-Link).
  • 🔴 Compilation error "arm-none-eabi-gcc: command not found":

    Solution: install the toolchain GNU Arm Embedded Toolchain via package manager or with ARM official website.

    • What to do if the IDE does not see the debug board?

    1. Check the physical connection (the USB cable must be for data as well as power).

    2. Update ST-Link firmware via STM32CubeProgrammer.

    3. On Linux, add a user to a group dialout: sudo usermod -a -G dialout $USER and reboot.

    4. On Windows, try reinstalling the driver manually via Close driver in STM32CubeProgrammer.

    ⚠️ Attention: If after the update STM32CubeIDE Old projects no longer open, check version compatibility STM32CubeMX And HAL libraries. For example, projects built in 1.10.0 may not compile to 1.14.0 without a code migration.

    Updating STM32CubeIDE to the latest version

    STMicroelectronics regularly releases updates for STM32CubeIDE - approximately once every 2-3 months. New versions contain:

    • 🆕 Support for new microcontrollers (for example, STM32H5 or STM32C0).
    • 🐛 Critical bug fixes (especially in the debugger and code generator).
    • 🔧 Performance optimization (faster compilation and simulation).

      • To update the IDE:

      1. Open STM32CubeIDE and go to Help → Check for Updates.
      2. If the update is not found automatically, download the new version from official website and install over the old one (the project settings will be saved).
      3. After the update, rebuild all projects (Project → Clean).

      ⚠️ Attention: When updating manually (installing a new version over the old one) don't delete the workspace folder — it contains all your projects and settings. However, it is recommended to make a backup (File → Export → General → Archive File).

      💡

      Update STM32CubeIDE only through official channels. Use of third party "patches" or "portable" versions may result in incompatibility with ST debugging tools.

      Alternative installation methods

      In addition to the standard installer, STM32CubeIDE can be deployed in alternative ways:

      • 📦 Portable version (Windows):

        Download the archive .zip from the official website and unpack it to any folder. Launch stm32cubeide.exe without installation. Disadvantage: lack of integration with drivers ST-Link (they will have to be installed separately).

      • 🐧 Installation via Snap (Linux):

        Run the command:

        sudo snap install stm32cubeide --classic

        Advantage: Automatic update via snap refresh.

      • 🖥️ Docker container:

        To isolate your development environment, use the image:

        docker pull stm32cubeide/stm32cubeide:latest

        docker run -it --device=/dev/ttyACM0 -v ~/STM32Projects:/workspace stm32cubeide

        Pay attention to the mounting of the device /dev/ttyACM0 (replace with your ST-Link port).

      For corporate users STMicroelectronics offers offline installers with pre-loaded packages. They can be requested via personal account (registration required).

      FAQ: Frequently asked questions about STM32CubeIDE

      🔍 How to find out the version of the installed STM32CubeIDE?

      Open the IDE and go to Help → About STM32CubeIDE. The version is displayed at the top of the window (for example, 1.14.0). Also the information is duplicated in the file version.ini in the installation folder.

      🖥️ Is it possible to transfer projects from Keil/IAR to STM32CubeIDE?

      Yes, but with reservations:

      1. Export your project from Keil/IAR to .uvprojx/.ewp.
      2. B STM32CubeMX import the file via File → Import → Existing Project into Workspace.
      3. Manually transfer custom code (files .c/.h) into the new project structure.

      Automatic conversion of peripheral settings (RCC, GPIO etc.) not supported — they will have to be configured again.

      ⚙️ How to change the path to the toolchain (compiler) in STM32CubeIDE?

      Go to Window → Preferences → STM32Cube → Toolchain. Here you can:

      • Select pre-installed GNU Arm Embedded Toolchain.
      • Specify a custom path to the compiler (for example, /usr/local/gcc-arm-none-eabi-10-2020-q4-major/bin).

      After changing the path, rebuild the project (Project → Clean).

      🔌 STM32CubeIDE does not see the Nucleo board. What to do?

      The problem is usually driver or power related:

      1. Check your USB connection (try a different cable/port).
      2. On Windows, update the driver via Device Manager (select STMicroelectronics ST-Link manually).
      3. On Linux, add a rule for udev (see section "Installation on Linux").
      4. Run STM32CubeProgrammer and check if the board is detected there (ST-Link → Connect).

      If the board is still not visible, try resetting it to factory settings (click RESET for 5 seconds).

      📁 Where does STM32CubeIDE store projects by default?

      Workspace folder (workspace) located:

      • On Windows: C:\Users\<Your_name>\STM32Cube\workspace.
      • On Linux/macOS: ~/STM32Cube/workspace.

      You can change the path when you first start the IDE or through File → Switch Workspace.
