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 ???

The easiest way to fix this is to separate the FIS directory from the
FCONFIG database - basically
into two separate FLASH sectors. Then Linux will let you write to them.
Rebuild RedBoot with CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG false

Hi Gary
Thanks,
Well,instead of changing RedBoot,I have modified the code
'mtdpart.c".(linux-2.6.x/drivers/mtd)
if ((slave->mtd.flags & MTD_WRITEABLE) &&
(slave->mtd.size % slave->mtd.erasesize)) {
// slave->mtd.flags &= ~MTD_WRITEABLE;
slave->mtd.flags &=MTD_WRITEABLE;
printk ("mtd: partition \"%s\" doesn't end on
an erase block -- force read-only---Hacked ;-)\n",
parts[i].name);
}
Now,I am able to read/write "RedBoot config" partition. ;-)
Thanks for the help
