Build Openwrt
=============

Get trunk build
 svn checkout https://svn.openwrt.org/openwrt/trunk/ .

Configure and compile:
 make

Get the resulting binary
 ./trunk/bin/openwrt-ar7-squashfs.bin



Prep the original DG834G(v2)
============================
Login via web and enable the telnet debug access:
 	http://192.168.0.1/setup.cgi?todo=debug

Telnet to the unit and set ADAM2's IP
	echo "my_ipaddress 192.168.0.1" > /proc/sys/dev/adam2/environment

Set up a new partition mapping for the upcoming openwrt kernel:
	echo "mtd5 0x90020000,0x903e0000" > /proc/sys/dev/adam2/environment

Start to backup the partitions:
	cd /tmp/ ; mini_httpd -p 1080
	cat /dev/mtdblock/0 > /tmp/mtd0.bin
	cat /dev/mtdblock/1 > /tmp/mtd1.bin
	cat /dev/mtdblock/2 > /tmp/mtd2.bin
	cat /dev/mtdblock/3 > /tmp/mtd3.bin
	cat /dev/mtdblock/4 > /tmp/mtd4.bin

Get them off onto a remote machine:
	wget 192.168.0.1:1080/mtd{0,1,2,3,4}.bin

Check their md5sums: (V3.01.31)
	ubuntu@ubuntu:~$ md5sum mtd*
	f0f416c9a4ae22a1f3f97eaf66c3fc91  mtd0.bin
	eff06c398966943975576cffdef2f0c7  mtd1.bin
	0530bfdf00ec155f4182afd70da028c1  mtd2.bin
	21f235faae279e147d41cf5622e75834  mtd3.bin
	f63240ca1c3b6d87d9658ad884656794  mtd4.bin

Modify ADAM2 only if mtd2.bin == 0530bfdf00ec155f4182afd70da028c1
	TODO Noodles:

It should result in a binary with an md5sum of d8a2f4623bf6f64b7427812f0e849aa7

Get the new image back onto the router using wget:
	cd /tmp
	wget http://192.168.0.3/mtd2.bin
	dd if=mtd2.bin of=/dev/mtdblock/2
	rm mtd2.bin

        wget http://192.168.0.3/openwrt-ar7-squashfs.bin
        dd if=openwrt-ar7-squashfs.bin of=/dev/mtdblock/5
        rm openwrt-ar7-squashfs.bin

(2nd batch of commands takes around 30 sec)

Reboot
	reboot


Same method using ADAM2
=======================
Connect RJ45 to router and as you power on the unit, issue:

sleep 2 ; ftp 192.168.0.1

Log in with adam2/adam2
Get the env settings
	get env


Ensure a environment variable mtd5 spans the kernel and rootfs partion

 ftp> quote GETENV mtd5
 mtd5                  0x90020000,0x903e0000


If not, set it:

	quote SETENV mtd5,0x90020000,0x903e0000



Issue the commands (case sensitive)

 type binary
 hash
 debug
 quote MEDIA FLSH
 put openwrt-ar7-2.6-squashfs.bin "openwrt-ar7-2.6-squashfs.bin mtd5"
 quote REBOOT

 (whole process takes ~ 30 sec)

Let the router come up, and then power it off and on again. This lets it write correctly any non-stardard IP settings.

YOU CANNNOT UPDATE ADAM2 using ADAM2!!!!!!

To Restore via ADAM2
====================

 type binary
 quote MEDIA FLSH
 put mtd0.bin "mtd0.bin mtd0"
 put mtd1.bin "mtd1.bin mtd1"
 quote REBOOT




Setting up Openwrt
==================

Telnet to the router on 192.168.0.1 and set a root password
 passwd

Append the following to /etc/config/network :

config interface wan
 option ifname   ppp0
 option username "user@isp"
 option password "password"
 option proto    pppoa
 option mtu      1500
 option mru      1500
 option vpi      0
 option vci      38
 option encapsulation    vc-encaps

To Restore via Openwrt (not totally sure yet)
======================

ADAM2's view

mtd0                  0x900d0000,0x903e0000	<---These both must be restored
mtd1                  0x90020000,0x900d0000	<---
mtd2                  0x90000000,0x90020000
mtd3                  0x903e0000,0x903f0000
mtd4                  0x903f0000,0x90400000
mtd5                  0x90020000,0x903e0000

Openwrt's view
0x00000000-0x00010000 : "loader"	(is this too short?)
0x003f0000-0x00400000 : "config"	mtd4?
0x00020000-0x003f0000 : "linux"		mtd5 (just over?)
0x000e24b4-0x003f0000 : "rootfs"	latter parts of mtd5


We need to have the same map regions as ADAM2 to get the original firmware back on.
Conclusion, Openwrt's view of things may not be correct.
