nrf51288-DK storage

Hello, I'm new to Espruino, however I really like it!

I've built nrf51288-DK Espruino image to play with an nrf51288 chip. It mainly works, e.g. Bluetooth stuff, reading digital analog pins etc. However I can't get it to store something in EEPROM. I'm following some example where you need to load a module, e.g. Storage, Flash etc but non of them actually loads...

I've got a simple code that does:

require("Storage");
console.log(Storage.debug());

This print the following:

Uncaught Error: Module Storage not found
 at line 29 col 18
require("Storage");
                 ^

Does it mean that nrf581 chip does not support Storage?

PS. I've tried to load "Flash" module with the same result.
