Hi,
     You can write into flash from linux if you have mapped the flash in mtd
partition. you can open /dev/mtdx(partition that covers your flash
area) file and use normal read/write function calls to read/write from the
flash. Remember to erase the flash before attempting to write data. You can
refer sourcecode of mtd-utils.

Regards
Ratheesh
