How to save my static IP address?

Hi I changed my IP address using connmanctl cmd as below link.
I want to use static IP and save this configuration. But after reset the IP address is reset and I should set IP again manually.

How to save this configuration? I want to use fixed IP after reset.

my version is 2015.12 aungstrom


Hi guys I cleared this issue.
I used rc-local service and /etc/rc.local file. You can go find on google this service.

I wrote ifconfig eth0 inet 192.168.0.x netmask
in rc.local file.

When every boot up sequence, ifconfig cmd in rc.local file automatically executed.

I wish this method helpful for you guys.
