MKW30Z Oscillators

Hello All,


I'm in the process of bringing up an MKW30Z and doing the hardware checkout.  One of the things I like to do with any hardware is confirm that the clocks and voltages are working as needed before I give the board to my programmers.  While all my voltages check out, my clocks don't seem to work.  I've used the same crystals as the freedom board so I know the crystal is sufficient and even tried adjusting the load capacitors.  I'm not a software guy but reading the development guide, it appears you can turn on and off the clocks.  Should a new, blank chip, start the oscillators on power-up with the RESET  (PTA2) line held high?  Or do I have to wait for the software guys to get in there an enable the clocks in code through JLINK?
