    This is the problem. Two boards Aduc7026 (Olimex and Analogdevices eval) at identical program show different speeds from the gpio output at maximum core clock

      This is the problem. Two boards Aduc7026 (Olimex and Analogdevices
      eval) at identical program show different speeds from the gpio output
      at maximum core clock (CD=0). About 70nS AnalogDevice versus 120nS
      Olimex delay set in thumb mode. I monitoring clock P0.7 is correct
      both 41.7MHz.

      Nevertheless when CD=1 two boards have same 140nS delay set.

      Someone for this behavior?
