Update: I misread the R1 value initially. And the cheap voltmeter from home mislead me into seeing a toggling SCK pin.
Using my work gear, R1 now reads correctly at 1KOhm, and I was able to trace the problem back to a poorly soldered down pin 17.
Fixed.

I just got my TinyDuino from Makershed at the Maker Faire. The Arduino Blink example did not work.
My board is an ASM2001
rev 5.
I checked the schematics of ASM2001+ASD2101 and the LED is hooked up to
SCK via R1. SCK (pin 13 as per
http://arduino.cc/en/Hacking/PinMapping168) leads to the ICSP connector which
is toggling as expected.
A
diode test with my voltmeter
turns the LED on.
The resistance of
R1 reads as
1MOhm! Schematics of ASM2001 rev6 say it should be
1KOhm.
ASM2001 rev5 is not checked into github.
Is the ASM2001 rev5 board not a happy board?
Are the changes between rev5 and rev6 easy enough for me to do or should I just get a replacement?
