    My kernel is 2.6.16.16 with AT45DB642 dataflash
    The program isn't dies always, but it return none message, when it dies, such as segment
 Fault or failure to load a library. But it can run well if I run ./filename when it dies.
    It dies when open a file but not return anything. I heard someone say when jffs2 mount
 successful, don't open file to read or write immediately, just wait 30-40 seconds, Maybe 
it scan the flash after mount. Is that right?
