Bootloader中的哪个函数将NK.bin解压成NK.nb0
网上看见很多人说NK.bin和NK.nb0都可下载到RAM中，如果下载到RAM的是NK.bin文件因为是压缩的，需要先通过BootLoader进行先解压才能往NAND Flash中烧写。

我用的平台是PXA270+Wince6.0 ,板子的Eboot就是通过以太网下载NK.bin映像到板子上内存，再写入FLASH的，但是就是不知道Bootloader中的那个函数将NK.bin解压成NK.nb0

解压缩的代码在PUBLIC\COMMON\OAK\DRIVERS\ETHDBG\BLCOMMON\blcommon.c中的函数

下面是我的DownloadImage函数
static BOOL DownloadImage (LPDWORD pdwImageStart, LPDWORD pdwImageLength, LPDWORD pdwLaunchAddr)
{
    BOOL        rval = TRUE;
    DWORD       dwImageType;

    *pdwImageStart = *pdwImageLength = *pdwLaunchAddr = 0;
KITLOutputDebugString ("\r\nUnable to read image signature.\r\n");

    //
    // Download each region (multiple can be sent)
    //
    do
    {
        dwImageType = GetImageType();
       
        switch(dwImageType)
        {
          
            case BL_IMAGE_TYPE_BIN:
                rval &= DownloadBin( pdwImageStart, pdwImageLength, pdwLaunchAddr );
                break;

            default:
                // should never get here
                return (FALSE);
               
        }
    }
    while (--g_downloadFilesRemaining);

    ComputeChecksum();

  if(g_EbootCFG.Store_In_NandFlash)
  {
  //  NandflashInit();

     if(FlashFormated == FALSE)
      {

           BP_LowLevelFormat((DWORD)g_dwStartBlock,(DWORD)(NUM_BLOCKS - g_dwStartBlock),0) ;
 }

      rval &= WriteImageToFlash();

  #if   0

  KITLOutputDebugString ("create partition.\r\n");
  BP_OpenPartition( NEXT_FREE_LOC,
                                USE_REMAINING_SPACE,
                                PART_DOS32,
                                TRUE,
                                PART_OPEN_ALWAYS);while ( OEMReadData (sizeof (DWORD), (LPBYTE) &dwRecAddr) &&
  OEMReadData (sizeof (DWORD), (LPBYTE) &dwRecLen) &&
  OEMReadData (sizeof (DWORD), (LPBYTE) &dwRecChk) )

这就是一段一段在解压   
  #endif 
  }
