How can I get that pointer? Unfortunately I cannot simply use theaddress 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?
