The information available so far is the USB protocol at
http://stuge.se/qiprog_protocol.txt and beyond that there's the
LPC11U14 schematic in my head along with some PCB layout ideas, the
more advanced of which is the QFN33 chip on a flex(-rigid) PCB with
edge pads that align with a 200 mil SO8 outline, for soldering
directly onto the existing flash chip, and some 10-15 cm of flex
circuit ending in a flex-rigid section with a micro-USB connector.

The first PCB will of course more likely be plain and simple, maybe
even with QFP, and edge pads for flash chip as well as USB
