    I believe you can use the FS module to access some extra storage.

    Format the extra partition using http://www.espruino.com/Reference#l_E_fl­ashFatFS
    you can then use the extra space availible on the ESP32 board.

    I've got some code that is both hosting a webserver and polling sensors for data.

    The sensor polling uses timeouts to provide a wait time for the sensor to respond, and the webserver uses the standard pageRequest function to parse the request and serve information back to the client. html, js and css files are held in storage and are read out in chunks on request.

    I'm assuming its something to do with timers, and the storage module as I can disable the polling and it works fine.

    this was all working fine in version 2.8, but I tried version 2.10 yesterday and now if try and load the page served by the module whilst running the polling loop I get the error 'Execution Interrupted during event processing.' I get this lots of times.

    Any thoughts on what might have changed between v2.8 and v2.10 that might cause this and how one might resolve the issue.

    Is it possible to get the reset info on the ESP32 like it is on the ESP8266?

    Is there a way to parse the startup text that is displayed on the console to get the reset info?

    I'm using a ESP32 to listen for BLE packets and I'm getting the occasional error. Any ideas on how to figure out the issue?

    I've been flashing ESP's for ages with Espruino and this is the first time I've seen this.

    I've got a really simple bit of code:

    function main() {
     var BTN = 12;
      var rgb = new Uint8ClampedArray(3*3);
      var pos = 0;
      function getPattern() {
        for (var i=0;i<rgb.length;) {
          rgb[i++] = (1 + Math.sin((i+pos)*0.1324)) * 127;
          rgb[i++] = (1 + Math.sin((i+pos)*0.1654)) * 127;
          rgb[i++] = (1 + Math.sin((i+pos)*0.1)) * 127;
        return rgb;
      setInterval(function() {
        require("neopixel").write(14, getPattern());
      }, 100);
    pinMode(12, 'input_pullup');
      setWatch(function(e) {
        console.log('bttn pressed');
      }, 12, { repeat: true, debounce:100, edge: 'falling' });
    E.on('init', main);

    Just to flash some LED's and listen to a button press, and if I type save in the console to store the code, I just get an endless loop of errors reading this:

    in function called from system
    Uncaught SyntaxError: Got [ERASED] expected EOF
    at line 1 col 1

    I'm sure I'm flashing the correct firmware (the V2.08 4mb ESP8266 version)

    Any ideas?
