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,
