MPC5645S and DDR2 MT47H128M16 - 25E

Is the DDR2 RAM Memory supported by the MPC5645S MCU?

On a project, I used 2 DDR2 RAM "MT47H128M16 - 25E" to obtain a 32-wide data bus. I write a configuration but the DDR2 RAM doesn't work very well.  I think that I don't initialize it correctly the DDR2 by EMR Register. Have you some examples or have you already a good configuration ?

 

Thank you for advance.
