关于6410下wince6.0的nandflash 分区问题 [复制链接]

cpu:6410,os:wince,nandflash是256M的，吧nandflash的前64M固定下来，后面192M是exfat分区，修改如下：
eboot中的loader.h中修改
原先：
//#define RESERVED_BOOT_BLOCKS        (NBOOT_BLOCK_SIZE + TOC_BLOCK_SIZE + EBOOT_BLOCK_SIZE)

#define RESERVED_BOOT_BLOCKS SECTOR_TO_BLOCK(FILE_TO_SECTOR_SIZE(0x4000000))  /*屏蔽前面64M空间*/

nandflash中的fmd.c中修改
函数：FMD_GetInfo
原先：
//  pFlashInfo->dwNumBlocks         = NUM_OF_BLOCKS;
修改后:
    pFlashInfo->dwNumBlocks         = NUM_OF_BLOCKS - 512;     /* 512是64MB*/

重新烧制boot和nk.bin后，wince启动不了:

感觉是nandflash驱动读取分区死了，不知道什么原因？高手指点一下
