One way is to create an init.d script. That's a nice clean option.
- Make a new petalinux application
- Create an init.d script (bash script that can take an argument of "start", "stop", "restart")
- In your application's recipe, add:
inherit update-rc.d
INITSCRIPT_NAME = "name_of_your_initscript"
INITSCRIPT_PARAMS = "defaults 90"
And in your do_install() function, add:
install -d ${D}{sysconfdir}/init.d
install -m 0755 ${S}/name_of_your_initscript ${D}${sysconfdir}/init.d/name_of_your_initscript
Inside your init.d script, you can use start-stop-daemon to background a task, save PID files, etc.
