19.Customized service management

This course takes the newly created OLED startup service as an example for reference only to the service management process. The Yahboom Muto image has been set up to start the oled service automatically at boot.

1. Create a new service file

ExecStart represents the command to be executed and the command needs to be executed according to the actual modification.

Jetson nano system service files:
