Hi,
you may setup a dedicated partition that gives you access to the particular
location in the flash where you whant to place this data. Then you can use
normal open() read() write() and seek() functions to access what ever byte in
this partition. How to erass a block you can look up in one of the MTD tools.
(Only if you are using NAND flash you should not do it like this since bad block
handling whould be missing.)
But I aggree with Thomas. Best whould be to put it into a filesystem...
