save() not work on ESP32

A simple code like this:

function setup_sim800c() {
console.log("Hello, SIM800C!");
}

E.on('init', function(){setup_sim800c();});

then click send to Espruino button, after done, enter "save()" in left IDE window:

save()
=undefined
Erasing Flash..................

Compressed 80000 bytes to 3036

Hello, SIM800C!

things seams OK, but reset the board, nothing printed. setup_sim800c symbol is not found either.
...
Loading 3036 bytes from flash..

...try with the 'old' onInit() { setup_sim800c(); };. If this does not help, defer the invocation of setup_sim800c() with a setTimeout(). Since nothing is printed, I'm not sure where the print goes... can you flash some LED on a pin?

not work, after save(), log is printed. but reset the board, cannot see the hello string except boot messages.

function setup_sim800c() {
console.log("Hello, SIM800C!");
}

function onInit() {setup_sim800c();}

save()
=undefined

Have you got saved code from previous firmware?

If you erase the flash and then reflash the firmware, and upload the code, I think it will be ok.....

Which firmware version are you running?

I am having same problem with the save(). I have my own onInit() called in the save.

Mine was not working also... and a full reflash makes it save again.

I believe that the flash gets corrupted when the core crashes... and it does a lot.

I find mine crashes a lot too. Does anyone have any insight why it's so unstable? Is it issues with the Espruino port or something else. Does it depend on the specific board -- are some more stable than others.

I think the powersupply has a lot to do with it.

Yeah this has happened to me too a few times. If I see anything that reproduces it reliably I'll post something.
