Can it be moved to the ToH or is the information incorrect? — Jo-Philipp Wich 2010/03/22 13:41

The default proprietary bootloader only accepts signed images with a special header.
Accepted signatures are:
Those images can be created by OpenWrt.
However the bootloader consumes quite lot's of space and there is an uboot port for this platform available.
I prepared a signed image (http://nanl.de/files/openwrt/airties/openwrt-lantiq-danube-ARV4520PW-BRNDANUBE-brnImage_signed_flash_uboot_and_combined) which - once flashed and started - replaces the original bootloader with uboot and flashes an OpenWrt image.
Images (kernel+rootfs) created by OpenWrt can be run by the proprietary bootloader as well as uboot as the kernel takes care about the used environment and choose a respective partition layout.
Uboot has an webserver integrated which gets activated by pressing the "WLAN"-button during power-on. Over its web interface you can now easily flash your actual firmware image of choice.
In short - using mentioned image above:
The uboot port provides HTTP functionality for uploading Firmware images via your webbrowser. To connect to the bootloader via HTTP you require a direct Ethernet connection (no switch in between involved)!
If you want to upgrade using TFTP you follow these steps (as an alternative to the above install process.
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
cd /tmp/ wget http:// mtd write /tmp/0 linux && reboot

Not needed, you can recover it via serial. See Restore Uboot
The default network configuration is:
|Interface Name||Description||Default configuration|
|br-lan||LAN & WiFi||192.168.1.1/24|
|vlan0 (eth0.0)||LAN ports (1 to 4)||None|
|vlan1 (eth0.1)||WAN port||DHCP|
Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
The analog phones (on the FXS and ISDN lines) are handled with the Infineon PEF 4268T SLIC DC/DC controller. Then it is possible to configure "Telefon 1(F)", "Telefon 2(U)" and "Telefon 3(ISDN)"
Analog phones can be plugged on the TAE-Stecker and TAE-Buchsen phone socket on top of the device with the TAE-to-RJ11 adapters (details on the TAE-type sockets here : http://de.wikipedia.org/wiki/Telekommunikations-Anschluss-Einheit). ISDN phone can be plugged on the ISDN phone socket.
If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.
The failsafe mode is only available via the serial connection with OpenWrt 12.09 (Codename "Attitude Adjustment").
Later versions might work but I did not test that, yet. There are 3 different buttons: "WPS", "WLAN on/off" and "RESET" which might trigger the failsafe mode in the later versions. If you press and hold the reset button when you switch the device on, then the uboot bootloader will go into failsafe mode and will make web server available under http://192.168.1.1/ (see below). If you want the OpenWrt failsafe mode (and not the uboot bootloader fail-safe mode) then you need to wait 4-5 seconds before you press and hold the reset button.
NOTE: The root file system in failsafe mode is the SquashFS partition mounted in readonly mode. To switch to the normal writable root file system run mount_root and make any changes. Run mount_root now.
uci get network.lan.ipaddr
mtd -r erase rootfs_data If you are done with failsafe mode power cycle the router and boot in normal mode.
If you bricked your uboot you can load a functional one via uart. For that you need to bridge r64 (top) and r80 (bottom) with some solder. After that the soc boots up in UART mode. You can verfy that you are in UART-Mode if after powering up the device it writes the follwoing on the serial:
ROM VER: 1.0.3 CFG 04 Read EEPROMX X UART
Now you can transfer your u-boot.asc through a serial connection:
cat u-boot.asc > /dev/ttyUSB0
There exist quite a few more Modes, that are accesible through briding empty pads as shown in this thread. But none other than default and UART-Mode seems to be usefull.
