Programming MAX96717F and MAX96714F

Question

HI, 
 I am using SerDes MAX96717F Ser and MAX96714F Des (MAXIM INTEGRATED) along with raspberry pi 4 to get the output of Raspi Camera on RPi4. 
 1: The pipeline has been generated using the GMSL gui through script generation. 
 2: Once cpp file is loaded, i am able to get the display at the Rpi4. 
 The issue is whenever i power cycle the boards. I need to load the script again to get the output. 
 How can i program it for once and use it even after power cycle? 
 Any leads?

A short guide that will work on the PI OSes. It uses systemd. (summary of an e14 project that uses system services)

create a service script

sudo nano /etc/systemd/system/raspicam.service

[Unit]
Description=Raspberry Pi camera service
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
WorkingDirectory=/<path to where you want the software to run>
ExecStart=/<command line of script / program to run. Can include parameters>
Restart=always
RestartSec=30
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=raspicam
User=<yourname>
Group=<yourname>

[Install]
WantedBy=multi-user.target

register it

sudo systemctl daemon-reload

enable and start

sudo systemctl enable raspicam.service

sudo systemctl start raspicam.service

check status:

systemctl status raspicam.service

This will start the program, running as the user you put in the script. If for some reason you want to run it as root*, remove the User and Group lines.
