I have read somewhere, that when a program is saved on Espruino and we flash a new version it will maybe not work, because there are many changes in the new version. Then reset(), save() and then flash.
By the way, I had the the unreleased on my Espruino, but nothing saved, so I could do the flash with no trouble.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
