Hi all:

Recently, I am trying to collect analog data into the flash and save as a file by using MDBT42Q.
Below is the example code in the Data collection part I used to explain my trouble:

var storage = require("Storage");
var FILESIZE = 65536;
var count = 0;
var file = {
  name : "",
  offset : FILESIZE, // force a new file to be generated at first
};

// Add new data to a log file or switch log files
function saveData(txt) {
  var l = txt.length;
  if (file.offset+l>FILESIZE) {
    // need a new file...
    file.name = file.name=="log2"?"log1":"log2";
    // write data to file - this will overwrite the last one
    storage.write(file.name,txt,0,FILESIZE);
    file.offset = l;
  } else {
    // just append
    storage.write(file.name,txt,file.offset);
    print(count);
    count += 1;
    file.offset += l;
  }
}

// Write some data
setInterval(function() {
  saveData(getTime()+","+E.getTemperature()+"\n");
}, 10);

The trouble is that: When I change the FILESIZE bigger than 32*1024(32768), my Web IDE will just stuck and return nothing.
I have try require("Storage").eraseAll(), reset() and save(), it is all useless.
In the attachment is some information about my memory usage.

Thank you guys very much!
