Sorry for bumping an old post, but I’m in the same situation.
My device was fully working with a customized-firmware I built from your repo. Two days ago, I performed some modifications (adding new drivers), and after flashing, no lights and no serial access, so It might be a dead EPROM.
I have the tools to reflash it even without desoldering, but I can’t find the file anywhere, only references to it in forum threads.
So, how can I get the magic 16MB bin file to reprogram the flash?
Very many thanks, Manuel
