1. Installation

1.1. Bill of Materials

You will need:

• A tftp server
• A telnet client
• A copy of the OpenWRT kernel (openwrt-atheros-vmlinux.lzma)
• A copy of either the squashfs or jffs image (openwrt-atheros-root.squashfs or openwrt-atheros-root.jffs2-64k)

1.2. Process

1. Connect your computer's ethernet port to the router's LAN port.
2. Set your computer's IP to 192.168.1.254.
3. Place the two images in the same directory on your computer, and start your tftp server serving that directory.
4. Unplug the router.
5. Start your computer pinging 192.168.1.1.
6. Plug in the router.
7. As soon as you see a reply to the ping, telnet 192.168.1.1 on port 9000.
8. As soon as you see the connection made, type ^C. You have 2 seconds from the router first booting to press ctrl-C.
9. Now issue the following commands to copy the flash, note that each fis create command will take a significant amount of time. The first will take aproximately 5 minutes, while the second about 10-15. During this time the router will lock up totally and become unpingable. Do not touch it:

fis init 
load -r -v -b 0x80041000 openwrt-atheros-vmlinux.lzma
fis create kernel
load -r -v -b 0x80041000 openwrt-atheros-root.squashfs
fis create -l 0x6f0000 rootfs

(replacing squashfs with jffs2-64k as required).

10. Issue fconfig -l When asked for a boot script, enter the following including the final new line. Leave all other settings unchanged, and answer yes, to save the config.

fis load -l kernel 
exec

11. Issue the following commands to start OpenWRT. Once you have done this, you should see the OpenWRT banner, and a normal bash prompt:

fis load -l kernel 
exec

12. Configure OpenWRT! You're done.

2. Other Information

Serial port pinout (front to rear) is GND,RX (input to the Fonera),TX (output from the Fonera),3.3V

To backup the flash, take a copy of the following partitions:

dev:    size   erasesize  name
mtd0: 00030000 00010000 "RedBoot"
mtd1: 00010000 00010000 "loader"
mtd2: 00620000 00010000 "image"
mtd3: 0055c000 00010000 "rootfs"
mtd4: 00310000 00010000 "rootfs_data"
mtd5: 00010000 00010000 "config"
mtd6: 00140000 00010000 "image2"
mtd7: 0000f000 00010000 "FIS directory"
mtd8: 00001000 00010000 "RedBoot config"
mtd9: 00010000 00010000 "board_config"

Note that rootfs, rootfs_data and config are all inside "image", so you don't need to backup partitions 3, 4 and 5.
