How can I get that pointer?  Unfortunately I cannot simply use the
      
address of the flash.  Is there some magical function call that
gives me access to that portion of the memory space?
    
$ man 2 mmap

You want MAP_SHARED and O_SYNC.
    

To use that I need to have a file descriptor to a device, do I not?  However, I do not have a base flash driver to give me that file descriptor.  Am I missing something with that call?
  
/dev/mem


b.g.
