WinCE MMC空间分配

本来三星的MMC是这么做的：

//SDMMC BSP Definition
#define IMAGE_NK_SIZE  (0x040E0000)

#define FATFS_FOR_IMAGE		(0x1000000)
#define SECTOROFFATFS		(FATFS_FOR_IMAGE / SDMMC_SECTOR_SIZE)


#define IMAGESTARTSECTOR (MBRSTARTSECTOR+SECTOROFMBR) 
#define IMAGESIZE           (IMAGE_NK_SIZE)
//#define IMAGESIZE (0x10000000) // this value must be the same as Flash size in the memory.cfg.xml
#define SECTOROFIMAGE (IMAGESIZE/(SDMMC_SECTOR_SIZE))



#define MBRSTARTSECTOR (TOCSTARTSECTOR+SECTOROFTOC+7) // 7 sector means tocsector+7, to align 8KB
#define SECTOROFMBR         (0x100)

#define SECTOROFTOC (8)
#define TOCSTARTSECTOR (AISSTARTSECTOR+SECTOROFAIS) // to align 8KB

#define SECTOROFAIS (1) // Address Information Sector
#define AISSTARTSECTOR (BOOTIMAGESTARTSECTOR+SECTOROFBOOTIMAGE+15) // to align 8KB

#define SECTOROFBOOTIMAGE (0xA10) // bootimage means STEPLDR+IPL+EBOOT
#define BOOTIMAGESTARTSECTOR (1)

//#define STEPLDRBUFFER 0x50200000
//#define STEPLDRSTARTADDRESS	0x50000000
#define SECTOROFSTEPLDR (0x20) //16K
#define STEPLDRSTARTSECTOR (1)

#define SECTOROFEBOOT (0x600)
#define EBOOTSTARTSECTOR (STEPLDRSTARTSECTOR+SECTOROFSTEPLDR)

#define SECTOROFIPL (0x400)
#define IPLSTARTSECTOR (EBOOTSTARTSECTOR+SECTOROFEBOOT)

然后我改成这样子：

//SDMMC BSP Definition
#define IMAGE_NK_SIZE  (0x040E0000)

#define FATFS_FOR_IMAGE		(0x1000000)
#define SECTOROFFATFS		(FATFS_FOR_IMAGE / SDMMC_SECTOR_SIZE)

#define IMAGESTARTSECTOR (MBRSTARTSECTOR+SECTOROFMBR) 
#define IMAGESIZE           (IMAGE_NK_SIZE)
//#define IMAGESIZE (0x10000000) // this value must be the same as Flash size in the memory.cfg.xml
#define SECTOROFIMAGE (IMAGESIZE/(SDMMC_SECTOR_SIZE))

#define MBRSTARTSECTOR (LOGOSTARTSECTOR+SECTOROFLOGO) // 7 sector means tocsector+7, to align 8KB
#define SECTOROFMBR         (0x100)

#define SECTOROFTOC (8)
#define TOCSTARTSECTOR (AISSTARTSECTOR+SECTOROFAIS) // to align 8KB

#define SECTOROFAIS (1) // Address Information Sector
#define AISSTARTSECTOR (BOOTIMAGESTARTSECTOR+SECTOROFBOOTIMAGE+6) // to align 8KB

#define SECTOROFBOOTIMAGE (0x421) // bootimage means STEPLDR+EBOOT
#define BOOTIMAGESTARTSECTOR (1)

//TOCSTARTSECTOR = 0x429 
//AISSTARTSECTOR = 0x428 
//SECTOROFBOOTIMAGE = 0x421 
//LOGOSTARTSECTOR = 0x431 
//BOOTIMAGESTARTSECTOR+SECTOROFBOOTIMAGE = 0x422 

//#define STEPLDRBUFFER 0x50200000
//#define STEPLDRSTARTADDRESS	0x50000000
#define SECTOROFSTEPLDR (0x20) //16K
#define STEPLDRSTARTSECTOR (1)

#define SECTOROFEBOOT (0x400)
#define EBOOTSTARTSECTOR (STEPLDRSTARTSECTOR+SECTOROFSTEPLDR)

#define SECTOROFLOGO (0x3000)
#define LOGOSTARTSECTOR (TOCSTARTSECTOR+SECTOROFTOC)

三星的表格可能没处理详细，会有数字错误，这么做的原因是加上LOGO的分区，使得跟其他操作系统可以公用Logo
