开贴探讨WINCE6.0 XIP模式的实现

 WINCE5.0的XIP模式,很早就实现了,最近在想WINCE6.0上实现XIP,但是结果失败.不知道有没有前辈大虾已经实现的.

WINCE6.0架构和WINCE5.0有很大区别,原来的5.0的NK.EXE已经被分成几个小块了,OAL.EXE,KERBEL.DLL等等,另外用户模式下一些对底层硬件操作也有所限制,例如VirtualAlloc等函数就不能支持操作,另外在5.0下经常应用的KernelIoControl,自定义IOCTL操作也不好用了,IOCTL已经成为一个单独的OALIOCTL.DLL并且只支持
    switch (dwIoControlCode) {    
        case IOCTL_HAL_GET_CACHE_INFO:
        case IOCTL_HAL_GET_DEVICE_INFO:
        case IOCTL_HAL_GET_DEVICEID:
        case IOCTL_HAL_GET_UUID:
        case IOCTL_PROCESSOR_INFORMATION:
            // request is to service the ioctl - forward the call to OAL code
            // OAL code will set the last error if there is a failure
            fRet = (*g_pfnExtOALIoctl)(dwIoControlCode, pInBuf, nInBufSize, pOutBuf, nOutBufSize, pBytesReturned);
        break;
        default:
            SetLastError(ERROR_NOT_SUPPORTED);
        break;
    }
不管那些,按照原来5.0的经验支持修改让它支持XIP

2: 修改注册表

ENDIF ; BSP_NONANDFS
; END HIVE BOOT SECTION

在6.0下有cachefilt.dll但是还没有具体研究这个有撒用处

3: 修改WINCE特性,加入BINFS TFAT STOAREMANAGER 等,使用HIVE注册表,使用ROM ONLY文件系统

4: 修改CE.BIB让下面为XIPKERNEL包含
nk.exe
kernel.dll
hd.dll
kd.dll
osaxsto.dll
osaxstl.dll
coredll.dll
oalioctl.dll
k.coredll.dll
filesys.dll
romfsd.dll
exfat.dll
diskcache.dll
cachefilt.dll
fatutil.dll
relfsd.dll
binfs.dll
imgfs.dll
rawfs.dll
romfilter.dll
fsdmgr.dll
fsdacl.dll
mspart.dll
ceddk.dll
boot.hv
initdb.ini

5:编译正常,正确生存XIPKERNEL.BIB NK.BIN CHAIN.BIN XIP.BIN 和 CHAIN.LST文件

支持将XIPKERNEL.NB0下载到XIPKERNEL区域,运行,下面为结果:

不能正常初始化NANDFLASH.....

6: 修改CE.BIB 加入WINCE.NLS到XIPKERNEL,这个文件在5.0下我是没有包含进去的,后不出现'Data Abort
结果:
FSDMGR!DllMain: DLL_PROCESS_ATTACH
FSDMGR!STOREMGR_Initialize
FSDMGR!InitializeStoreAPI

FSDMGR!AutoLoadFileSystems: CurrentBootPhase=2, LoadFlags=1

NANDFLASH还是不能正常初始化.
