Using external DDR2 on TWR-K70F120M

I start to work on the kinetis TWR-K70F120M demo board to prototype a client application requiring an extended RAM size. I chose this board because an external 1GB DDR2 RAM is integrated.


I 'd like to use this external RAM without an operating system (MQx or other). I'm using Code Warrior.


I'm trying to configure manually the DDR controller with the processor expert. Please, can you explain me step by step how to configure the project to work with the external DDR2 and how can I use it ?
