Hello, I'm new here, english is not my native language, but I'm gonna do my best.
I need to know in wich zone or byte(s) could I write a few lines (in flash memory) that do not get erase after format the flash.......
I really apreciate any help...thanks in advance
pasted by Emilio, from a fake answer ...
The flash that i'm talking about is the normal memory flash that people usually use daily, you know to transport photos and the normal things that normal users usually do, not embedded or sd.......but are you saying that we normally haven't privileged to access to the flash ?.......
To be exact:
I have a group of flash memories, not sd, just the common memories that we use to transport information all the time. the problem is that i need to mark this flash and asociate this mark with some password that the user of the flash could has.. I could do this encripting some file and copying it like normal data into the flash memory, but the problem is that it is a common file that any user could see and erase as you said, i need to achieve that in a low level(I guess) that the common user could not see the mark and even could not erase it by normal ways
