  • To exit the simulator, press control + c in the terminal or click on the control bar icon.

Running the Simulator on Linux

You need to get administrator privileges before starting the simulator. $ is normal privileges and # is administrator privileges.

Or execute the following command.

sudo chmod -R 777 /dir
  • -R means that the cascade is applied to all subdirectories and files in the directory
  • 777 means that all users have the highest privileges
  • /dir is the target folder, this can be the simulator installation directory, usually /opt/simulator

If your installation directory is in /opt you can execute it in the terminal next, if not, you need to execute it in your own installation directory to install the environment.

cd /opt/simulator/resources/firmware/ && sudo ./setup_for_linux.sh
