Just had a play with the flasher (have updated the code). I can get it to erase the device, but something is broken when it tries to write data to it.
There were some issues with conversion between datatypes that I had to fix in EspruinoTools (String/ArrayBuffer/Buffer), and I wonder if there are still some problems there.
