还是FAT文件系统加载问题!

zxhnet 2009-7-16 13:15 楼主

大家好!

这里再次向大家请教一下FAT文件系统的加载问题!

最近我把FLASH中作了这样的分区,开头的是NK,紧接NK的block放的是MBR,然后空了一个block,再接着的8个block(1M)分区为FAT32,再后面的部分我就没有分区了.我的MBR在sboot里给写在了第41个block(前面40个block用做存放NK.NB0--5M字节),1个block有256个sector,1个sector有512字节,总共有512个block,共64M字节,现在当我加载的时候出现了下面的现象:关键是最后出现了一个DEBUGCHK failed

我的分区如下:
hPart = BP_OpenPartition( 10752,
                           2048,
                           PART_DOS32,
                           TRUE,
                           PART_OPEN_ALWAYS);

这里的10752=40*256+256(MBR)+256(空出的block)

请大家赐教啊!!!

万分感谢yashi 斑竹的关照！！

哪个出错的地方在这：

BOOL CDiskInterface::WriteSectors (DWORD dwSector, LPBYTE lpBuf, DWORD dwNumSectors)
{
SG_REQ sg;
DWORD dwResult;

sg.sr_start = dwSector;
sg.sr_num_sec = dwNumSectors;
sg.sr_num_sg = 1;
sg.sr_status = ERROR_NOT_SUPPORTED;  // not used by ATADisk
sg.sr_callback = NULL;
sg.sr_sglist[0].sb_buf = (LPBYTE) MapPtrToProcess(lpBuf, GetCurrentProcess());
sg.sr_sglist[0].sb_len = m_dwBytesPerSector * dwNumSectors;

dwResult = DeviceIoControl(m_hVolume, DISK_IOCTL_WRITE, &sg, sizeof(sg),
      NULL, 0, NULL, NULL);

if (!dwResult) {
      ASSERT(0);／／就是这里出错的！！！
      DEBUGMSG(ZONE_OUTPUT, (L"Write Sector failed (%d) when writing to Sector %d\r\n", sg.sr_status, dwSector));
      SetLastError(ERROR_WRITE_FAULT);
}

return dwResult;
}

现在情况是这样的，上面的问题已经解决，通过改变FMD_ReadSector里的　pSectorInfoBuff->bOEMReserved = 0x02就可以了，可是又出现了新的问题，

停住的地方和上面的问题一样，只是报了不同的错误．我觉得可能是
这句打映消息　NumSec=107520 BytesPerSec=512 FreeSec=0 BiggestCreatable=0
中的 FreeSec=0造成的，但是这个参数该如何改变呢？？

请斑竹不吝赐教！！

7楼 pl89721

刚更改了一下sboot里的分区：

hPart = BP_OpenPartition( 256,  // next block of MBR
                        2048 ,// USE_REMAINING_SPACE 改为　２０４８
                        PART_DOS32,
                        TRUE,
                        PART_OPEN_ALWAYS);

现在我把上面的第２个参数改为2048后，
出现了

虽然FreeSec不为０了，但是问题依旧，说明问题不在这里！
