Thanks for the tip.  I do turn on PLL very early - in first dozen
instructions or so.  

 

I do sometimes have trouble gaining control - get illegal CPU ID.  Power
cycling the board (and resetting the CPU)  does seem to help that.  But I
don't see how it would cause BSOD.  

 

IAR has been pretty good on compiler issues.  They swapped out the JLink,
hoping that it was hardware, but the driver failures are still happening too
often.

What does IAR say?  I have found their tech support good.  We are 
using this exact combo with good luck.  One question, are you 
enabling the PLL and when?  I found that if enabled at program start 
up JLINK had trouble gaining control of the CPU.
