MPC5645S to use LPDDR controller for MT46H16M16LFBF-6

Question asked by shuai xu on Sep 3, 2017


      I have a question about MPC45S for driving MT46H16M16LFBF-6. I have initialized the LPDDR, and modified the .lcf file according to the guidance. But there is still 0x00 after I  changed the value of 0x2000 0000 address. While I can observe the waveform changes of the CLK  CS and Data pins using an oscilloscope.

      The attachment compressed file is the project and PDF is the  schematic. I doubt there is any problem in the initialization operation, or you can give me some suggestions. Thank you very much!


      Best regards!
