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

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。
