The CryptoCape, a collaboration between SparkFun and myself, is now
available for purchase at SparkFun Electronics [1]. In short, the cape
adds some hardware crypto chips, a RTC with battery, and an ATmega328p
which is designed to be flashed from the Beagle. It will be officially
announced on the "new products Friday" post tomorrow, but I think this
group deserved an early announcement.
Thanks to BeagleBoard.org for making a great platform and special
thanks to Robert Nelson for backporting the TPM driver to 3.8.
This community is awesome; I've learned so much by following this
list. Thanks to everyone who shares their time and knowledge.
There's only 1 left :)
Happy Hacking!

How is the RTC implemented at the software level? More to the point
perhaps, how early in the boot process does the system time get set from
(presumably) rtc1?
About a month or so ago I setup a battery backed RTC, along with a
fairly current systemd. Systemd have chosen to rewrite hwclock and last
I looked it still only honored/used rtc0. Perhaps I didn't explain the
situation good enough on the systemd mailing list, but I couldn't seem
to get past anyone not understanding why a board wouldn't have a battery
backed RTC on board. Having said all that I did get it working just
using init.d scripts. Just seems like such an ugly hack when the whole
point of systemd is to essential do away with all the scripts.
The board looks like something very interesting to explore. I'm sure
one will find its' way here when cash flow permits.
