DDRAM of ADSP-21469 Evaluation KIT

Hello!

 

 

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:

 

Memory{.......

  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!
