[ECOS] Can I change 'RedBoot Config' using MTD driver. ?

["Amitesh Singh" <singh dot amitesh at gmail dot com>]

Hi all
 My Task is to set "Boot script" (RedBoot config) value via a linux
command.

As on RedBoot prompt,we set configurations using 'fconfig',is there any
Linux tool which does the same ?

i tried to do it in my way.

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00040000 00020000 "RedBoot"
mtd1: 00f80000 00020000 "unallocated"
mtd2: 00001000 00020000 "RedBoot config"
mtd3: 00020000 00020000 "FIS directory"


First i copied 'mtd2' using 'dd' and then changed the binary using 'hexedit'
(just changed Boot script).
Before booting,I unlocked RedBoot partitions.

RedBoot> fis unlock "FIS directory"
... Unlock from 0x50fe0000-0x51000000: .
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I am able to read/write other partitions (including FIS directory (have n't
checked for RedBoot :P) ) except "RedBoot config".
Any suggestions ???
