I tried your webserver with the latest binaries, and it is running fine.
Sometimes you have to do the upload twice, I don't know why (the first time you get a reset, and the next time it works)

- Sun Oct 18, 2015 6:29 am #31641 @Markus Gritsch I think this is the same bug. :)

But now I saved a new js code, and I cannot use the board anymore couse it is alwayes resetting, how can I save() a new empy code, or stg working code?

thanks

Re: Example: simple webserver

By Markus Gritsch
- Sun Oct 18, 2015 8:40 am #31649 I had the same behaviour yesterday, after saving the simple webserver example in the onInit() function.

Reflashing the board with the Espruino binaries does also not help, because this does not overwrite the respective region in the flash, where the state is saved when calling save().

So depending on the firmware upload software you use you have to erase all flash, or flash the empty bin to the board, to overwrite the saved state.
