将剩余nor flash 划分分区问题

将剩余nor flash 划分分区问题 [复制链接]

我的平台是PXA270+Wince6.0，32M Intel P30 NOR Flash
使用MSFALH来将flash剩余容量利用起来，遇到了一些问题，也有一些疑问，请大家帮忙一下。
如果使用RAM运行， 分区划分成功，可正常显示盘符，也可以正常读写。
但如果选择 IMGFLASH 写入flash后， fmd_driver 一调用  write_command 命令读写flash就死机。造成没法启动。

我查了很多资料，也参考了前辈大侠们的一些帖子，我现在的做法是：
1、在catolog中加入MSFLASH驱动
2、修改注册表和platform.bib文件。
有几个疑问如下：
3、对于MS提供的MSFLASH驱动，我查了一些资料，发现似乎不用修改这个驱动，直接使用即可，只需要在注册表中进行正确的设置。请问是这样吗？

NK.bin 大小是 20M, 我将最后5M划分为一个分区。
OEMtable中关于flash的信息如下：

C/C++ code

        DCD     0x9CA00000, 0x00000000, 32      ; MAINSTONEII: nCS0: Boot Flash (32MB).



我的注册表资料如下：

从debug（imgflash）版本输出信息来看
在操作 write_command 发生 Data Abort 异常，
但是如果是RAM运行，则正常， 望指导下，谢谢

大家帮忙给个建议，谢谢

没人建议?
只好暂时使用 binfs方式将OS NK拷贝到内存来运行,
可是可用内存少了20M,

难道 NOR FLASH XIP模式不能和剩余分区同时存在?
大侠们给个指示.谢谢

大侠，在norflash用xip跟不用xip差别不大啊，相反不断对norflash进行读写会降低其使用寿命
