So I was lucky enough to join in the OLPC XO 1.5 bringup at Quanta in
Taipei. This was great fun: I wrote an Openfirmware HDAudio driver
and we used it to test and debug parts of the main board. I got to watch people doing
cool things with soldering irons, oscilloscopes, LPC ROM emulators,
and other implements of destruction. Mitch debugged the memory controller interactively using a Forth that fits strictly in cache - that's a nice trick.
Bringups are fun! I would do another :-)
