Hi All,

I have to write to flash memory 2 pocket of data one of them is always 14 b=
ytes and the second one may very 110-128 bytes of data. the way flash memor=
y works is
I can't rewrite like EEPROM is. in order to rewrite entire sector needs to =
be erased and after erase all cells becomes logic 1. the reason I mention t=
his is if verification failed I have to ignore and go next. in my case I ha=
ve 2 uart and one of them is 14 byte rx data coming in and the second one 1=
20 byte rx. as soon as the data comes in I have to store in to flash. =A0al=
l data are mixed =A014 bytes or 120 bytes can be mixed order and different =
information. =A0the size of flash is 4000000 bytes. the way I see it easies=
t way to save data is to define maximum data size lets say 130 bytes and st=
ore data every 130 bytes regardless of 14 bytes or 120 bytes is coming in. =
so the data will be stored every 130 bytes and to read back it will be ever=
y 130 bytes witch makes it easy to read. another way I was thinking is to a=
dd start and end character and when it comes to read back i just look for s=
tart and end character. total record can go up to 25000. I am not sure
 if I explained clearly. on top of this since i already knew about flash I =
also added 256kb eeprom to store location information where was last saved.=
 my question is what's the best way do you think to store data in flash and=
 read back all.=A0

any idea?

thanks
