Known Issues and Limitations#

Changes from Studio v5 behavior are marked with an asterisk (*). While not necessarily issues or limitations, these changes may affect existing workflows.

Installer 1.0.0#

• Restricted Access Support: Early Access and Controlled Access installations are not supported in this release.

• Studio shortcut: For Windows and Linux, a Studio launch shortcut is only available on the Desktop. On macOS, the installer does not place a shortcut for Simplicity Studio in the root Applications folder or on the Desktop by default. Instead, a Simplicity Studio shortcut is created under the user’s Applications folder (typically /Users/<username>/Applications/SiliconLabs).

  • Workaround: On macOS, navigate to your Applications folder, /Users/<username>/Applications/SiliconLabs, and locate the Simplicity Studio shortcut. Copy the shortcut into the root Applications folder (requires administrator privileges) or drag it to the Desktop for quick access.

• Installation path (*): The installation path for the Package Manager cannot be customized by the user.

• Installer version information: The Simplicity Installer does not include an About menu or version information in the UI that displays the Studio version on Windows.

  • Workaround: On Windows, locate the SimplicityInstaller.exe file on your system (C:\Users\<YourName>\AppData\Local\Programs\SimplicityInstaller). Right-click the file, select Properties, and go to the Details tab for the version number.

  • Workaround: On Linux, you can run the following command: apt show simplicityinstaller

Studio 6.0.0#

• Project Generator: An HTTP 404 error may appear in the Project Configuration step of the new project wizard when generating a project.

  • Workaround: Close the new project wizard window and retry the operation.

• Device Selector dialog: Limited filtering functionality by protocol.

• Matter Provisioning Tool: Not available in this release.

• IAR project generator: Not available from the new project wizard view.

  • Workaround: Described in the Select a Target IDE section.

• Multiple instance support (*): Running multiple instances of the same version of Studio simultaneously is not supported.

• Software updates (*): The Studio UI does not include an Updates indicator.

  • Workaround: Open Package Manager from the Simplicity Installer to check for updates.

• Bug report (*): No Bug Report option is available.

  • Workaround: Capture log files specified in Reporting an Issue section.

• Adapter FW Update: The Device Overview UI may not indicate that Adapter FW version 2.0.0 is available for the connected board.

  • Recommendation: Open Device Manager to manually check for and apply the firmware update. Or close and reopen the Device tab.

• Windows BSOD with Older Adapter FW: When using Adapter Firmware versions earlier than v2.0.0 may cause a Blue Screen of Death (BSOD) on Windows.

  • Recommendation: Update your development board to Adapter Firmware v2.0.0 or later, which uses the Microsoft winUSB driver.

• Studio version information: Simplicity Studio does not include an About menu or version information in the UI that displays the Studio version.

  • Workaround: Open Package Manager and view the installed Studio version displayed.

• Pintool: The Pintool does not function correctly if the project path contains spaces.

  • Workaround: Avoid using spaces in the project path or project name or else use the component editor for pin configuration.

SDKs#

• Matter: On Windows, Matter projects from Matter SDK 2.7.0-1.4 (CSA Matter 1.4.2), released with SiSDK 2025.6.2, fail during compilation due to a known GCC 12.x bug related to long command line length. 

  • Workaround: See Knowledge Article.

• SixG301: The SixG301 devices are supported only with CMake/GCC. (IAR is not supported.)

  • Workaround: Refer to the Known Issues and Limitations section for additional details.
