WINCE NAND FLASH eboot 创建多个分区

?方法一：

1.??????三星原厂两个分区的实现方式

1.1??WriteOSImageToBootMedia函数

?// create extended partition in whatever is left

???//

???hPartEx = BP_OpenPartition( NEXT_FREE_LOC,

???????????????????????????????USE_REMAINING_SPACE,

???????????????????????????????PART_DOS32,

???????????????????????????????TRUE,

???????????????????????????????PART_OPEN_ALWAYS);

?

???if (hPartEx == INVALID_HANDLE_VALUE )

???{

???????OALMSG(OAL_WARN,(TEXT("*** WARN: StoreImageToBootMedia: Failed to open/create Extended partition ***rn")));

}

上面的代码为除了nboot、TOC、eboot和nk之外的空间创建一个FAT32的分区。

?

1.2??Platform.reg注册表信息

?

IF BSP_NONANDFS !

; HIVE BOOT SECTION

?

[HKEY_LOCAL_MACHINESystemStorageManagerProfilesSMFLASH]

???"DefaultFileSystem"="BINFS"

???"PartitionDriver"="mspart.dll"

???"MountHidden"=dword:1

???"MountAsROM"=dword:1

???"Folder"="ResidentFlash"

???"Name"="Microsoft Flash Disk"

?

; Keep FATFS from trying to shadow Windows

[HKEY_LOCAL_MACHINESystemStorageManagerProfilesSMFLASHFATFS]

???"MountHidden"=dword:0

???"MountAsROM"=dword:0

?

[HKEY_LOCAL_MACHINEDriversBuiltInSMFLASH]

???"Prefix"="DSK"

???"Dll"="smflash.dll"

???"Index"=dword:1

???"Order"=dword:0

???"Profile"="SMFLASH"

???"IClass"="{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"

?

[HKEY_LOCAL_MACHINESystemStorageManagerFATFS]

???"Flags"=dword:00000014??????? ;FATFS_TFAT_ALWAYS|FATFS_FORCE_TFAT

????

[HKEY_LOCAL_MACHINESystemStorageManagerAutoLoadSMFLASH]

???"DriverPath"="DriversBuiltInSMFLASH"

???"LoadFlags"=dword:1

???"BootPhase"=dword:0

?

; END HIVE BOOT SECTION

ENDIF ; BSP_NONANDFS

?

系统起来后可以看到ResidentFlash盘符，文件系统是FATFS。

1.3???

2.??????三个分区的实现

?

2.1??WriteOSImageToBootMedia函数

?

// create user partition size

hPartEx1 = BP_OpenPartition(NEXT_FREE_LOC,

SECTOR_TO_BLOCK_SIZE(FILE_TO_SECTOR_SIZE(SYS_PARTITION_SIZE))*PAGES_PER_BLOCK,// align to block

?PART_DOS32,

?TRUE,

?PART_OPEN_ALWAYS);

?

if (hPartEx1 == INVALID_HANDLE_VALUE )

{

?OALMSG(1,(TEXT("*** WARN: StoreImageToBootMedia: Failed to open/create Extended partition?1111 ***rn")));

}

?

hPartEx2 = BP_OpenPartition( NEXT_FREE_LOC,

USE_REMAINING_SPACE,

PART_DOS32X13,

TRUE,

PART_OPEN_ALWAYS);

?

if (hPartEx2 == INVALID_HANDLE_VALUE )

{

?OALMSG(1,(TEXT("*** WARN: StoreImageToBootMedia: Failed to open/create Extended partition 2222***rn")));

}

这里需要注意，创建的两个分区所采用的是不同的文件系统，分别是PART_DOS32和PART_DOS32X13。

另外使用ADS分区的，也有使用应用程序的，不过我没实现，始终没成功。望知道的人分享探讨下。
