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

CPU: BCM63281KFBG - As found in these routers
RAM: Winbond 64MB DDR2
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.
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.
FLASH: cFeon EN25Q128-104FIP (128Mb) 16MB SPI Serial Flash
RAM: Winbond W9751G6KB-25 (512Mb) 64MB DDR2 RAM

Please check out the article Flash Layout. It contains an example and a couple of explanations.
|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.
|Bootloader tftp server IPv4 address||FILL-IN|
|Bootloader MAC address (special)||FILL-IN|
|Firmware tftp image||Latest OpenWrt release (
|TFTP Transfer Window||FILL-IN seconds|
|TFTP Window Start||approximately FILL-IN seconds after power on|
|TFTP Client Required IP Address||FILL-IN|
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.
- 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
- 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 After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
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 Linksys WRT54GL has two buttons. They are Reset and Secure Easy Setup. Here, we merely name the buttons, so we can use them in the above Howto:
|Secure Easy Setup||ses|
|Flash size:||8MB for DANT-T / 16MB for DANT-1|
|Flash Chip:||MX25L6445EMI for DANT-T / cFeon EN25Q128-104FIP for DANT-1|
|RAM size:||64 MiB|
|RAM Chip:||Winbond W9751G6KB-25 (512Mb) 64MB DDR2|
|USB:||Yes 1 x 2.0|

How to connect to the Serial Port of this specific device:
The Serial pins can be found on J3 (next to the JTAG at J4) on the PCB, you have to short-circuit R62 and R63.

How to connect to the JTAG Port of this specific device:
The JTAG pins can be found on J4 (single-row, pin 1 is on top) on the PCB, you have to short-circuit R180 to bring power (3.3V) on pin 1.
1 - N/C (resistor missing to 3.3V) 2 - N/C (3.3V Pullup / Possible nTRST) 3 - TCK 4 - TMS 5 - GND 6 - TDO 7 - TDI 8 - N/C (Diode missing to 3.3V)
