AVM FRITZ!Repeater 1200

Under Construction!
This page is currently under construction. You can edit the article to help completing it.

Write a short, relevant description of the device. Include a technical overview, but avoid marketing buzzwords/useless stuff. Two to four sentences is about right. A picture is good, too. Edit the page to see how to add pictures.

FIXME Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.

  1. Grab the uboot for the Device from the u-boot-fritz1200 subdirectory. Place it in the same directory as the eva_ramboot.py script. It is located in the scripts/flashing subdirectory of the OpenWrt tree.
  2. Assign yourself the IP address 192.168.178.10/24. Connect your computer to one of the boxes LAN ports. (1200 has only one port)
  3. Open three times a commandline
  4. 1st. cmd-window pings the 192.168.178.1 continuously
    2nd. cmd-window pings the 192.168.178.2 continuously,
    3rd. cmd-window Hold everything ready to fire up the follow comand:
    > ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz1200.bin
  5. Connect power to the box and take a look to the window where you ping 192.168.178.1. If there will be a respone, you have to execute the command above
    If you get an response from 192.168.178.2 - you are to late and you have to repower it.
  6. The U-Boot will now start. Now assign yourself the IP address 192.168.1.70/24. Copy the OpenWrt initramfs (!) image to a TFTP server root directory and rename it to FRITZ1200.bin.
  7. The box will now boot OpenWrt from RAM. This can take up to two minutes.
    At this Point, you can open the Webgui, but WIFI is missing, in cause of missing “Firmware/Packages”
  8. Copy the U-Boot and the OpenWrt sysupgrade (!) image to the box using scp. SSH into the box and first write the bootloader to both previous kernel partitions:
       > mtd write /path/to/uboot-fritz1200.bin uboot0
       > mtd write /path/to/uboot-fritz1200.bin uboot1
  9. Remove the AVM filesystem partitions to make room for our kernel + rootfs + overlayfs:
       > ubirmvol /dev/ubi0 --name=avm_filesys_0
       > ubirmvol /dev/ubi0 --name=avm_filesys_1
  10. Flash OpenWrt peristently using sysupgrade:
       > sysupgrade -n /path/to/openwrt-sysupgrade.bin

FIXME Find out flash layout, then add the flash layout table here (copy, paste, modify the example).

Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.

FIXME The instructions below are for Broadcom devices and only serve as an example.
Remove / modify them if they do not apply to this particular device!

This section deals with

  • How you install OpenWrt from a device freshly opened
  • The steps required such as reset to factory defaults if the device has already been configured

Note: Reset router to factory defaults if it has been previously configured.

  • Browse to http://192.168.1.1/Upgrade.asp
  • Upload .bin file to router
  • Wait for it to reboot
  • Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.

Specific values needed for tftp

FIXME Enter values for “FILL-IN” below

Bootloader tftp server IPv4 address FILL-IN
Bootloader MAC address (special) FILL-IN
Firmware tftp image Latest OpenWrt release (NOTE: Name must contain “tftp”)
TFTP transfer window FILL-IN seconds
TFTP window start approximately FILL-IN seconds after power on
TFTP client required IP address FILL-IN

generic.sysupgrade

FIXME These are generic instructions. Update with your router's specifics.

  • Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
  • Upload image file for sysupgrade to LuCI
  • Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

  • sysupgrade
  • mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

  • Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The default network configuration is:

Interface Name Description Default configuration
br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24
vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None
vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP
wl0 EXAMPLE WiFi EXAMPLE Disabled

FIXME Please fill in real values for this device, then remove the EXAMPLEs

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.

Port Switch port
Internet (WAN) EXAMPLE 4
LAN 1 EXAMPLE 3
LAN 2 EXAMPLE 2
LAN 3 EXAMPLE 1
LAN 4 EXAMPLE 0

hardware.button on howto use and configure the hardware button(s). Here, we merely name the buttons, so we can use them in the above Howto.

FIXME Please fill in real values for this device, then remove the EXAMPLEs

The AVM FRITZ!Repeater 1200 has the following buttons:

DANGER: HIGH VOLTAGE inside!
Opening this device exposes
parts under high voltage (110/230 VAC)!

  • Risk of deadly electrical shock
  • Risk of irreversable damage to other components attached, e.g. your PC connected via serial

Make sure to keep your fingers, conductive tools and serial cables away from the high voltage at all times!

Capacitors can still retain dangerous voltages
after disconnection from mains!

Continue at your own risk!

  • You will need a Torx screwdriver size T6.
  • The boards are held together by a long board to board pin connector. Be careful not to bend or break the pins when applying force.
