Hmm... It should work. I don't have time to check the actual image on a normal maple board again, but I think people (@bobricius?) do use it and it's fine.
You did use the ST flash utility rather than the maple one?
When flashed with Espruino it would communicate at 9600 baud by default so you could try that?
