Welcome to Jetson AGX Orin repository

Custom Service Management

This course uses creating a new OLED startup service as an example for reference only. The actual factory image already has the OLED service configured to start automatically at boot.

1. Create a new service file

Create a new file named yahboom_oled.service in the user directory.

xxxxxxxxxx
touch yahboom_oled.service
vim yahboom_oled.service

Add the following content: User represents the username (modify according to your actual username); ExecStart represents the command to be executed (modify according to your actual command).

System service file:

​x
[Unit]
Description=yahboom_oled start service
After=multi-user.target
​
[Service]
Type=idle
User=jetson
ExecStart=/bin/sh -c "python3 /home/jetson/software/oled_yahboom/yahboom_oled.py"
WorkingDirectory=/home/jetson
​
[Install]
WantedBy=multi-user.target

Then press Esc to exit editing, and type :qw to save the file.

2. Update the service

Copy the newly created yahboom_oled.service service file to the /etc/systemd/system/ directory.

xxxxxxxxxx
sudo cp yahboom_oled.service /etc/systemd/system/

Update system service

xxxxxxxxxx
sudo systemctl daemon-reload

3. Managing services

Check service status

xxxxxxxxxx
sudo systemctl status yahboom_oled.service

Start service

xxxxxxxxxx
sudo systemctl start yahboom_oled.service

Restart service

xxxxxxxxxx
sudo systemctl restart yahboom_oled.service

Set service to start automatically on boot

xxxxxxxxxx
sudo systemctl enable yahboom_oled.service

Stop service

xxxxxxxxxx
sudo systemctl stop yahboom_oled.service

Prevent service from starting on boot

sudo systemctl disable yahboom_oled.service
