Thanks for the reply.  I'm using a regulated bench power supply to 
run the Olimex board (and Wiggler).  To test your theory, I put a 
scope on the 1.8v and 3.3v lines on the Olimex board while attempting 
to write the flash and they're rock solid.  The board uses 800ma 
LM1117 regulators.

I seem to be having the same problem programming the flash as 
Microbit.  See my previous post for more info.

The problem with the PLL and clock speed is still a mystery.
