To run Simulink® models on Raspberry Pi™, you must enable passwordless sudo. Enabling passwordless sudo allows you to run Simulink models on Raspberry Pi without providing a password.
To enable passwordless sudo:
Log in to the Raspberry Pi command-line interface. The default user name and password of
the Raspberry Pi hardware are pi and
raspberry, respectively.
In the command-line interface, type this command:
sudo nano /etc/sudoers
Enable passwordless sudo access by adding this line:
<user name> ALL=(ALL:ALL) NOPASSWD:ALL
For example, to provide passwordless sudo access to a user
pi,
type:
pi ALL=(ALL:ALL) NOPASSWD:ALL

To save your changes, press Ctrl+x on your
keyboard.
For these changes to take effect, restart Raspberry Pi by typing this command:
sudo reboot
