Kinetis K61 or K70 tower DDR configuration

Hello all


I'm using the K70 tower kit and would like to load code from flash (etc.) to DDR2 and then execute from there. I have a few questions:

  1. Is this feasible? Is this a normal use-case for this micro controller?
  2. What kind of performance can be expected? Note: The current DDR configuration indicates that executing "a piece of code" (loop toggling a pin) from the DDR is ~5 times slower than executing it from internal flash, reasonable?
  3. Can anyone point me to the "optimal" configuration of the K70 tower board? Specifically for that combination of DDR2 and K70 CPU?


Any thoughts and/or ideas are appreciated Thanks!!
