Technicolor TG582n

Basic Information

The Technicolor Gateway TG582n (also referred to as the 582n or "BE Box v2") is manufactured by Technicolor (formerly Thomson, a spin-off of Alcatel) who describe it as a "Wireless n Multi-User ADSL2+ Gateway".

Board Versions & Hardware Differences

The TG582n comes in two distinct hardware variants distinguished by their Board Name. There are two board variants, namely DANT-T or DANT-1. Testing so far indicates that the PCB layout is identical for both board variants and that the only difference in hardware is the Flash chip (double the amount in DANT-1 boards).

The board variant as well as basic info such as firmware version, bootloader, etc can be accessed via the web interface of the stock firmware (default: 192.168.1.254):

TG582n System Information

DANT-T Boards

The DANT-T borads come with a 8MB Flash.

CPU: BCM63281KFBG - As found in these routers

FLASH: MX25L6445EMI - (64Mb) 8MB SPI Serial Flash - Link 1 Link 2

RAM: Winbond 64MB DDR2

WIRELESS: BCM43227

SERIAL: On J3, unpopulated, R63,R64 and C106 missing on my board.

JTAG: On J4, unpopulated, missing C111, R180, R66 and RN6 seem to suggest that this is infact a JTAG header.

Probably the serial port will work if i just bridge the pads, I will test later and update.

This could be a useful router with OpenWRT, as it has a USB port.

DANT-1 Boards

The DANT-1 boards come with 16MB Flash. The DANT-1 boards come with a dual-bank flash chip, able to store 2 firmware images and switch between them when the TG582n runs on stock firmware. The board layout is identical to the DANT-T one and the only difference seems to be the Flash chip.

CPU: BCM63281KFBG

FLASH: cFeon EN25Q128-104FIP (128Mb) 16MB SPI Serial Flash

RAM: Winbond W9751G6KB-25 (512Mb) 64MB DDR2 RAM

Flash Layout

Please check out the article Flash Layout. It contains an example and a couple of explanations.

OEM easy installation

FIXME The instructions below are for Broadcom devices and only serve as an example. Don't leave them in place if they do not apply to a particular device!

This section deals with how you install OpenWrt from a device freshly opened. Plus 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.

OEM installation using the TFTP method

Specific values you need

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

Upgrading OpenWrt

generic.sysupgrade

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.

LuCI Web Upgrade Process

Terminal Upgrade Process

  • Login as root via SSH on 192.168.1.1
  • Use the following commands to upgrade.

cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

  • If sysupgrade does not support this router, use the following commands.

cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Basic configuration

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

Specific Configuration

Interfaces

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
wl0 WiFi Disabled

Switch Ports (for VLANs)

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) 4
LAN 1 3
LAN 2 2
LAN 3 1
LAN 4 0
