There's a difference between flashing a partition and writing to a mounted filesystem. When you edit a file and change only one byte, the whole block containig this changed byte will be erased and newly written. This happens transparent to you. > and what is then the difference between /dev/mtd6 and /dev/mtdblock6 ? /dev/mtd6 is accessed as char device, while /dev/mtdblock6 is accessed as block device.
