Tested firmware created with script on Espruino Board from first Kickstarter campaign.
It works fine with latest release and with edge from github. Size of binary also matches those from your binaries folder
My problem is to create my own firmware.
Looks like I've to write a script to combine my firmware with bootloader. Something similiar to your create_espruino_image_1v3.sh
