[ECOS] loading redboot image on Avila board without JTAG or any flash programmer

["Bhanu Prakash Adhikari" <bhanua at aztecsoft dot com>]

Hi,

I succeed in building redboot with arm-elf toolchains.

I want to load redboot image for ROM or RAM on Avila board.

Do we have some guidance document or procedure to do it?

Setup Details -

	Avila
	IXDP425
	Linux 2.6
	ECOS Trunk snapshot (1 week old)

ls:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00080000 00020000 "RedBoot"
mtd1: 00140000 00020000 "zimage"
mtd2: 00320000 00020000 "ramdisk"
mtd3: 00b00000 00020000 "unallocated"
mtd4: 0001f000 00020000 "FIS directory"
mtd5: 00001000 00020000 "RedBoot config"

ls:~# ls -l /dev/mtd*
brw-r--r--  1 root root 31, 1 Jun  5  2006 /dev/mtdblock1
brw-r--r--  1 root root 31, 2 Jun  5  2006 /dev/mtdblock2
brw-r--r--  1 root root 31, 3 Jun  5  2006 /dev/mtdblock3
brw-r--r--  1 root root 31, 4 Jun  5  2006 /dev/mtdblock4
brw-r--r--  1 root root 31, 5 Jun  5  2006 /dev/mtdblock5
ls:~#


I find "redboot config" in /dev/mtdblock5.

1.	How can I access mtd0 when there is no corresponding mtdblock0
available? How can I get into mtd0 and manipulate it either to load
redboot or to tweak it?

2.	Does the patch mentioned at
http://mailman.uclinux.org/pipermail/uclinux-dev/2006-September/040068.h
tml  is applicable to mtd0 i.e., redboot partition also? Does the patch
make mtd0 also read-write?

3.	I referred the document
http://www.ecoscentric.com/ecospro/doc/html/ref/arm-ixdp425-setup.html
but all says they either require JTAG or some other device to load the
redboot image to board.
Is there any means that I can load without JTAG or any external flash
burners? If so, may I know how can I do it?


Thanks and rgds,
