DDRAM of ADSP-21469 Evaluation KIT

I have again a stupid problem. I can't use the 128 MB RAM of the ADSP-21469 Evaluation KIT.



I define the RAM size in the Linker File according the ADSP-21469 EZ-BoardTM

Evaluation System Manual as:



  seg_sram  { TYPE(DM RAM) START(0x00200000) END(0x021FFFFF) WIDTH(16)



But I can use only 512k Bytes, otherwise the memory content is wrong. It seems like a address overflow.



To configure I use the initPLL() from the demo programs.



Where is my error? Thanks!
