Espruino board does not work after save()

I have an espruino rev 1.4b board. I flashed it with the 1v86 firmware (WIZNet version). The sample program

var  on = false;
setInterval(function() {
  on = !on;
  LED1.write(on);
}, 500);

is working ok, but if I modify it

function onInit() {
  var  on = false;
  setInterval(function() {
    on = !on;
    LED1.write(on);
  }, 500);
}

and send it to the board and then, in the console, I type save(), the console prints "Erasing Flash.....ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ" and the espruino IDE hangs (I have to enter into a terminal and kill all chrome processes).

If I reset the board, the red and blue leds lit very dim and the board does not get enumerated in the IDE.

I have tryed many times to reset the board and inmediately push the BTN1 but it does not work. The only succesful method to recover it is enter in bootloader mode and reflashing it.

I've even tryed to type reset() and then save() in console but the result is the same: hanged IDE and board.

Am I doing something wrong? Is my board defective?

Thank you for your attention.

Best regards

Hi - sorry about this - looks like a bug in the 1v86 release. There's a test specifically to catch this issue, but it looks like somehow it's got broken.

I'll produce a new binary for you in a few minutes

Ok, if you update your firmware again it should be fixed now! Just tested with your code and instructions and it's fine.

Sorry about that - the size of the binary slowly crept up with things like Promises, and then started overlapping with the saved code area. I'm not sure how the build check got to the point where it was no longer working though.

It works!

Thank you very much for the fast response.
