Flashing

other notes

Building with default modules + debug causes luatool to fail with 'stdin:1: attempt to call field 'open' (a nil value)' since it seems file.open isn't defined. Rebuilt with fewer modules + debug and file upload seems to work fine. Did the build... just run out of space and truncate the image?
