Known issues and troubleshooting
Mbed Studio has the following known issues:
- Programs that you download from the Online Compiler as ZIP files contain a cut-down version of Mbed OS specific to the selected target. To select a different target, delete the Mbed OS library and replace it with a full copy of the library.
- Some users have reported licensing issues for Arm Compiler 6. These issues may be related to the system clock and region format.
- Trying to use Mbed Studio with Arm Compiler 6 on a remote desktop raises the FlexNet licensing error -103, because Arm Compiler 6 is not licensed for use in Remote Desktop setups. If you need to work in a Remote Desktop setup, please use GCC instead of Arm Compiler 6.
- Build output wraps on Windows.
- When you start a debug session, breakpoints are ignored until they are disabled and then re-enabled.
- Windows installer does not show the individual files or tools as they are installed, causing the progress bar to jump.
- On Linux, there is a limit on the number of files that can be watched in the workspace. Please follow the instructions on the Visual Studio documentation site to increase the limit.
- On Linux, C/C++ IntelliSense works only on Ubuntu 16.04 and 18.04.
- On Linux, source control management requires the
libcurl4package to work correctly.
- On macOS, if using the installer, you must uninstall the existing version of Mbed Studio before installing a new version.
- On Windows, the installation may fail if Windows system restart is pending.
- On Windows, you can only connect one external probe at a time. Mbed Studio may not find a probe if you connect multiples.

Switch Mbed Studio to GCC, instead of Arm Compiler 6.
Connected development board not found
- Update the board's firmware to the latest version:
- ST development boards on Windows require additional drivers. You can install them through the Mbed Studio installation, or download them from ST's site.
Development board not showing serial data
- Try to disconnect and connect the board.
- Check that no other program is accessing the serial data on the board; the device can only connect to one serial monitor at a time.
