Write to the flash configuration

Hi guys,
Its my first time using the tr-069 protocol, and I’d like to know if you can can make the router to save some config given by the tr-069 server. This way, if the servers gets down for some reason, the clients have some basic configuration.

I’ve tested the server with some FTTH clients, but every time the router get rebooted, the ACS needs to re-send all the config paramteres. I’d like to write to the flash some parameters using the ACS server.

Thanks for help!
