How to change my S5PV210 BSP code to utilize 512MB DDR2 memory? RRS feed

  • Question

  • I have physically 512MB DRAM on my platform.But my BSP only suport 256MB memory.How to change my S5PV210 BSP code to utilize 512MB DDR2 memory? Below is my BSP code:

    //
    //  File:  image_cfg.h
    //
    //  Defines configuration parameters used to create the NK and Bootloader
    //  program images.

  • If you're using a version of Windows CE different from Windows Embedded Compact 7 you can't use all the RAM: the OS can map 512 MB of memory but some ranges (in ARM CPU's like the one you're using) will be used to map the embedded peripherals (UART, memory controller, etc).

    In Windows Embedded Compact 7 you can take advantage of the new architecture, see:

  • Hi Mr.Vinoth

    Thanks for your reply.

    Wince only suport 512MB ram, it is not problem, but my system only have 256MB RAM, and my system have 512MB physical RAM. I don't to know how to modify my BSP.

  • Hi,

    Have you tried the define "BSP_V210_DDR2_512"?  

    Best regrads,

    Andreas

  • Thanks for reply. The "BSP_V210_DDR2_512" is defined by me. I have changed below code,but still not to work.

  • Windows CE only allows continuous physical memory for RAM to be configured as RAM in config.bib. Is your RAM continuous?

    If not, you have to use the function OEMGetExtensionDRAM() to map two separate physical memory sections.

  • Hi Calvin Liu :are you chinese?How to contact with you? This is my QQ :26451602. Did you had this issue resolved? Any other specialist could help me? Thanks

  • Hi zhengmeifu , Sorry I don't have a way to solve this problem now , from change setting "config.bib" , I just can increase the memory size (show in WinCE UI) to about 270M , if increase more , the NK.bin failed to start .

    ...

    ;#define    RAMLEN      01F00000   ;  default , for 240448 KB show in wince system 

    #define    RAMLEN       04F00000   ;  after setting , 240448 KB + (16*3)MB  can be show in wince UI 

    ... 

    I also try to modify the file your mention , but get the same result as you .

    yes I am in GuangZhou city or ShenZhen city  and not favorite chat at IM tools , anyway ,you can mail me anytime , calvinliu020@163.com

    Thanks !  

    Best Regards,
