Hi,

I'm trying to speed up iicbb by switching from DELAY to something with a higher \
resolution.  I figured I'd try to use the time-honored method of calibrating an I/O \
operation as a delay loop.  To my surprise, {get,}{micro,nano}uptime dont seem to be \
ticking during boot.

Am I doing something wrong? Is there an easier way to get a sub-microsecond delay?


Stefan
