reset() and save() question

Yesterday my 5 pucks arrived. @gordon - superb!

Started to play around a bit and just got stuck at a thing that happened to my pico before:

I tried out a demo, now I want to get rid of it.
So I connect and do this:

Connected
>
>dump()
var isOn = false;
setWatch(function () {
  isOn = ! isOn;
    analogWrite(LED1, (isOn) ? 0.02 : 0);
}, "D0", { repeat:true, edge:'rising', debounce : 49 });
setBusyIndicator(D3);
digitalWrite(D3, 1);
pinMode(D29, "input_pulldown", true);
=undefined

Call reset() to kill it:

>reset()
=undefined

Call save() to persist the "clean" state:

>save()
=undefined

Done!

Should be gone now, or not?
But look here - still there:

>dump()
var isOn = false;
setWatch(function () {
  isOn = ! isOn;
    analogWrite(LED1, (isOn) ? 0.02 : 0);
}, "D0", { repeat:true, edge:'rising', debounce : 49 });
setBusyIndicator(D3);
digitalWrite(D3, 1);
pinMode(D29, "input_pulldown", true);
=undefined
> 

So - how can I get rid of the running code?

Maybe I did not understand the concept of reset() and save() properly...

try

reset();save();

Thanks. Just tried.
Same result.
dump() still shows the old code...

hmm

only one line for a pinMode() coming from reset();

Maybe it's the WebIDE?
Chrome Version 54.0.2840.98 (64-bit) on OSX 10.11.6 here with WebIDE.

I played around with Settings->Communications->Save on Send.
When it is set to "Yes, even execute after 'reset()'" I can remove the code when:

• putting on dummy line like var foo; on the right hand pane
  
• click "Send to Espruino"
  
  

Simple example:

>dump();
function onInit() {digitalPulse(LED1, 1, 100);}
pinMode(D29, "input_pulldown", true);
=undefined

Not working:

>reset();save();
=undefined
Running onInit()...

Running onInit()...
>dump();
function onInit() {digitalPulse(LED1, 1, 100);}
pinMode(D29, "input_pulldown", true);
=undefined

Putting this into the right hand pane finally kills the code (actually it replaces the current code by some dummy code):

var foo;

Send and check:

This is strange...

hmm - missing reset(); in your last snippets, because it is not loading but clearing.

btw you should update your puck.js to 1v89
goto Puck.js and section Firmware Update

I suppose reset(); is done by the IDE and you can see it works - somehow.
The second puck was still 1v88 - you are right.
But it is the same with 1v89.

getting worse now after playing around with HID:

>reset();
=undefined

Question:
How can I reset the puck's memory to factory default?
reset() doesn't seem to work or have side effects.

check section "I saved some code and my Puck no longer works" on Puck.js

It's because of the Save on Send that was set in your IDE - obviously if you set it to Yes, even execute after 'reset()' then reset wont work :)

To force it to be removed, just run E.setBootCode() without arguments - it's the same for all Espruino boards. I'm wondering where the best place to add that to the docs is?

Oops - was missing that - Thank Gordon !
