S5PV210 WinCE6.0 使用双通道512MmDDR(256mx2)

主要有以下几个地方需要注意：

1. Image_Cfg.h

// DRAM1 Base Address
#define DRAM_BASE_PA_START(0x40000000)
#define DRAM_BASE_CA_START(0x80000000)
#define DRAM_BASE_UA_START(0xA0000000)
#define DRAM_BASE_PA_LAST(0x48000000)
#define DRAM_BASE_CA_LAST(0x88000000)
#define DRAM_BASE_UA_LAST(0xA8000000)
// Extra DRAM1 Base Address for V210
#define DRAM_EXTRA_BASE_PA_START(0x48000000)
#define DRAM_EXTRA_BASE_CA_START(0x99600000)
#define DRAM_EXTRA_BASE_UA_START(0xB9600000)
#define DRAM_EXTRA_SIZE                     (0x06A00000)
#define DRAM_EXTRA_BASE_UA_LAST(DRAM_EXTRA_BASE_UA_START + DRAM_EXTRA_SIZE)
// DRAM0 Base Address
#define DRAM0_BASE_PA_START(0x20000000)
#define DRAM0_BASE_CA_START(0x88000000)
#define DRAM0_BASE_UA_START(0xA8000000)
#define DRAM0_BASE_PA_LAST(0x28000000)
#define DRAM0_BASE_CA_LAST(0x90000000)
#define DRAM0_BASE_UA_LAST(0xB0000000)

2. oemaddrtab_cfg.inc

DCD DRAM_BASE_CA_START,             DRAM_BASE_PA_START,     128 ; 128 MB DRAM
DCD DRAM0_BASE_CA_START,            DRAM0_BASE_PA_START,         128 ; 128 MB DRAM on DMC0        
DCD BASE_REG_CA_CHIPID,             BASE_REG_PA_CHIPID,          43  ; 43 MB SFR,       0x9000_0000 - 0x92AF_FFFF

3. image_cfg.inc

;------------------------------------------------------------------------------; SDRAM ;------------------------------------------------------------------------------DRAM0_BASE_PA_START        EQU    (0x20000000)DRAM0_BASE_CA_START        EQU    (0x88000000)DRAM0_BASE_UA_START        EQU    (0xA8000000)DRAM0_SIZE                 EQU    (0x08000000);128M;------------------------------------------------------------------------------; SDRAM ;------------------------------------------------------------------------------DRAM_BASE_PA_START        EQU    (0x40000000)DRAM_BASE_CA_START        EQU    (0x80000000)DRAM_BASE_UA_START        EQU    (0xA0000000)DRAM_SIZE                 EQU    (0x08000000);128M;------------------------------------------------------------------------------; Extra DRAM for V210;------------------------------------------------------------------------------DRAM_EXTRA_BASE_PA_START  EQU    (0x48000000)DRAM_EXTRA_BASE_CA_START  EQU    (0x99600000)DRAM_EXTRA_BASE_UA_START  EQU    (0xB9600000)DRAM_EXTRA_SIZE           EQU    (0x06A00000);106M

4 . init.c

static DWORD OEMEnumExtensionDRAM(
  PMEMORY_SECTION pMemSections,
  DWORD cMemSections)
{
    DWORD cSections = 0;
    if (cSections < cMemSections)
    {
        // DRAM0 Area
        pMemSections[cSections].dwFlags = 0;
        pMemSections[cSections].dwStart = DRAM0_BASE_CA_START;  //0x88000000
        pMemSections[cSections].dwLen =  ONEDRAM_EXTSIZE_FOR_AP;
        cSections++;
        // Extra DRAM1 Area 0x48000000, 106MB
        pMemSections[cSections].dwFlags = 0;
        pMemSections[cSections].dwStart = DRAM_EXTRA_BASE_CA_START;  //0x99600000
        pMemSections[cSections].dwLen =  DRAM_EXTRA_SIZE;
        cSections++;        
    }
    return cSections;
}

image_cfg.inc貌似不改也没问题。

其余的关于内存的一些配置，在System_Init.c中，可以对照内存的Spec以及210手册中Memory配置部分即可。
