我的mini2440出现故障了，友善帮忙分析一下

出现问题的过程是这样的：我用U盘拷贝一个可执行文件到/opt/Qtopia/bin目录下，结果拷到一半，还没完成，出现LCD屏灭掉了，又闪了一下，接上串口线，看到一直在重启。
信息到
Uncompressing linux。。。。。。。这个地方就重启。。
我就关掉，拨到nor flash

都是在这个地方就重启了。
于是，我就重新格式化了一下 ，烧写supervivi, zimage和文件系统，重新刷一遍。
问题依旧。
我就把LCD屏先卸载了下来。结果发现启动了。
难道LCD坏了？？于是，我就把LCD屏插到另一块mini2440板子上，没问题，正常。

问题描述就这些。
请问友善帮忙分析看看。这是会是什么问题啊？我很急，这是我的毕业设计啊，。。
需要寄到厂子去吗？

我前面一些天，也是经常用U盘拷文件到那个目录，没有问题的。
我的mini2440是64M的NAND FLASH

可是我之前一直用都没出现问题的啊~~
因为我的板子是64M的，所以我一直以来都是用2009-4-29的版本。

版主，你好。谢谢你的回答。
我今天重新烧写nor flash。烧写supervivi-64M的，版本是0945-12
下面是NOR FLASH的BIOS信息。
于是我选“f”对NAND FLASH 进行格式化，提示失败？？难道是我的FLASH坏掉了？
