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.

When you say it hangs at boot - do you mean it's hanging when it's reset to send the code? or when you've saved the code and then reset the Espruino?
I've never been able to get the magic touch you quoted to work when I've gotten an Espruino wedged because I flashed a new bigram build after save()'ing with an old build with different data storage format.
That's why I made the flashclear script. When you flash firmware, the first 256k get erased - but the other 256k do not. Flashclear just erases those.
