Read data from MCP9808

the address is OK
I have check in some i2c scanner

I think something is wrong with the flash memory
because I have upload the code using the esperino IDE in chrome this time , selected RAM
and it's working , it print me the data

this is the code:

I2C1.setup({scl:D25,sda:D26, bitrate: 60000});
var mcp = require("MCP9808").connect(I2C1, 0b000);
console.log("I2C Setup Finsih");


function ReadTemp() { 
  
setInterval (function()
             {
  digitalWrite(LED1,0);
  var temperature = mcp.getTemperature();
  var TimeStemp = new Date().toString();
  console.log(TimeStemp + "  :  " + "Temperature: " + temperature + " C");
  setTimeout(function(){
  digitalWrite(LED1,1);
  },5000);} , 10000);}

ReadTemp();

I have used upload to RAM
and it's working

now I have enter save() , in order to make it work after reboor\power off - everything
got stuck:
can't write nothing in the console
get no replay
the led is off

this is what I have in the console after "save()"

>save()
=undefined
