WINCE XIP实现方法

==========================step1:========================================================

修改config.bib文件.内核子集XIPKERNEL的SIZE根据你自己编译出来的XIPKERNEL.BIN实际大小调整,

XIPKERNEL BASE=8C200000,XIPKERNEL SIZE = 0013F000 内存类型是RAMIMAGE

CHAIN BASE = XIPKERNEL BASE + XIPKERNEL SIZE; CHAIN SIZE = 00001000 内存类型是RESERVED

NK BASE = CHAIN BASE + CHAIN SIZE;

NK SIZE根据你平台定制的实际NK.BIN的大小调整,内存类型是 NANDIMAGE

RAM BASE = NK BASE + NK SIZE; RAM SIZE = 90000000 - RAM BASE,内存类型是 RAM.

pdwXIPLoc 是一个指定地址的全局变量,用于InitRomChain(),它的地址必须等于CHAIN BASE.

XIPSCHAIN=8C33F000 也必须等于CHAIN BASE.

ROMSTART=8C200000 ?

ROMWIDTH=32

ROMSIZE=00D00000

【注】PB能生成XIP.BIN，这项一定要定义XIPSCHAIN=8C33F000，不然生成不了XIP.BIN的。

在setting里 设置环境变量中，加上IMGMULTIBIN = 1，这个是对XIP BIN的支持，一定要加上。

==============================step3:====================================

?? 系统选用的文件系统必须是RAM and ROM Filesystem,不能用ROM Only.

==============================step4:====================================

要知道内核子集XIPKERNEL.BIN必须包含的modules和Files是那些,根据我的实践得出,51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> 下面这些文件是必需的:

?? ?"nk.exe",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"coredll.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"filesys.exe",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"fatfsd.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"diskcache.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"fatutil.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"binfs.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"fsdmgr.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"mspart.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"smflash.dll",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> ?? ?"boot.hv",51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> 其它的可选.

==============================step5:=====================================

使用preromimage.bat和processbib.exe程序,把它们拷贝到你的PLATFORM/SMDK2440/FILES/目录下.

到此改动就算结束了,下面就是开始Build and Sysgen.

生成了XIP.BIN之后烧写到NAND FLASH上,需要你的BOOT支持分区,在烧写的时候自动创建BINFS分区和FAT分区,51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> 如果不幸的你用的不是EBOOT的话又不能创建BINFS和FAT分区的话就麻烦大了.

系统起来之后可以看到有个BINFS目录和一个NandFlash目录.

==============================step6:====================================

?? ?最后一步,修改一下ce.bib的

?? ?XIPKERNEL ? ?8C200000 ?0013F000 ?RAMIMAGE

?? ?CHAIN ? ?8C33F000 ?00001000 ?RESERVED

?? ?NK ? ? ?8C340000 ?00D00000 ?NANDIMAGE

; ? ?RAM ? ? ? ? ? ? ? ?8D040000 ?02FC0000 ?RAM

?? ?RAM ? ? ? ? ? ? ? ?8C340000 ?03CC0000 ?RAM

使RAM的起始地址等于NK的起始地址,这里就是放大了RAM的空间,用命令行方式romimage ce.bib,51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> 生成XIPKERNEL.BIN的文件烧到NAND FLASH中去就可以了,有人有问题了发现XIPKERNEL.BIN太小烧不进去,51); font-family:Arial; font-size:14px; line-height:26px; text-align:left"> 在OEMVerifyMemory()判断里把它判断成了IMAGE_TYPE_RAMIMAGE,所以不写到FLASH了.把这段代码注释掉就好了.

/* comment for fix if the image too small and locate in range,then the image type will change to ram image and cause the image can not write to flash.

?? ?// Is it a ram image?

?? ?else if ((dwStartAddr >= ROM_RAMIMAGE_START) &&

?? ? ? ?((dwStartAddr + dwLength - 1) < (ROM_RAMIMAGE_START + ROM_RAMIMAGE_SIZE)))

?? ?{

// ? ? ?RETAILMSG(1,(TEXT("Downloading RAM image/r/n")));

?? ? ? ?g_ImageType = IMAGE_TYPE_RAMIMAGE;

?? ? ? ?return TRUE;

?? ?}

*/

好了,完成,你的程序内存将会是61774K左右.
