If you stumble across the "getting started page" FREEDOM BOARD / CORTEX M0+ GETTING STARTED  Please take note:


While working with a large number of Freedom boards in a course,  it was observed that the Init Clock Routines would *sometimes* not work.    *Some* of the crystals on the freedom boards do NOT like "HIGH_GAIN" mode. 


change the line


  pll_init(8000000, HIGH_GAIN, CRYSTAL, 4, 24, MCGOUT);



  pll_init(8000000, LOW_POWER, CRYSTAL, 4, 24, MCGOUT);
