 +Maybe one of the DANT-* boards in this page is actually a different model like TG582n PRO instead. In case, you can find more datasheets at [[https://github.com/hack-technicolor/hack-technicolor/tree/master/datasheets|github.com/hack-technicolor]]\\

-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 describes it as a "Wireless n Multi-User ADSL2+ Gateway".+The Technicolor MediaAccess TG582n Gateway (also referred to as different ISP-specific names, like the "BE Box v2" or "Modem Telecom Wi-Fi") is a product by Technicolor (formerly Thomson, a spin-off of Alcatel) and is marketed as a "Wireless n Multi-User ADSL2+ Gateway".
  
-Branding of this router (custom TR069 provisioning, web interface, packaging...) is generally commissioned to Technicolor/Thomson by many ISPs, such as Telecom Italia, BT/PlusNet, TalkTalk, Spark and many more.+Branding of this router (product names, custom TR-069 and default WAN settings, web interface, packaging...) is generally commissioned to Technicolor by many ISPs from different countries, such as Telecom Italia (IT), BT/PlusNet (UK), TalkTalk, Spark and many more.
  
-This router is fully compatible with OpenWrt Chaos Calmer 15.05 official release. Everything is supported (Ethernet, USB, wifi) with the exception of ADSL modem. If you need the ADSL modem part don'upgrade this box to OpenWrt. +This device is supported by OpenWrt since Chaos Calmer 15.05 official release. Supported features include Ethernet, USB, and Wi-Fi partially. As usual with Broadcom devices, the integrated DSL modem is not supported, and Wi-Fi functionality is limited to 802.11b/g only modes. If you need the DSL modem or the Wi-Fi 802.1n to be functional, please, don'flash this box with OpenWrt. 
  
 ==== Board Versions & Hardware Differences ==== ==== Board Versions & Hardware Differences ====
  
-The TG582n comes in at least three distinct hardware variants distinguished by their board name (DANT-1, DANT-T, DANT-V). The only difference seems to be flash chip, which is either 8 MiB or 16 MiB. Other than this, testing so far indicates that the PCB layout is identical for all boards.+The TG582n comes in at least three distinct hardware variants distinguished by their board name (DANT-1, DANT-T, DANT-V). The only hardware difference seems to be flash chip, which is either 8 MiB or 16 MiB depending on whether the device supports "dual bank" setup or not. Other than this, testing so far indicates that the PCB layout is identical for all boards. Each of them do only accept flashing its own firmware images as long as the stock bootloader is in place. 
 + 
 +When the flash chip is large enough, two firmware images (kernel+rootfs) can be kept flashed on the chip, and the bootloader automatically attempts to boot the "active bank" first. On a brand new device, only the first bank_1 contains a firmware. You can switch the active bank to the second bank_2 and get the stock bootloader attempt to boot that one by default. During a firmware upgrade, the new image gets flashed into the "passive" bank directly from a network download stream. On success, the active bank gets switched to the former passive one. The process of switching active bank is called "switchover"
 + 
 +This "dual bank" setup so provides a simple rollback feature: if the upgrade fails (eg. power cut during flashing, corrupted download), no active bank switch occurs. Also, if the active bank fails to boot 3 times in a row (e.g. because of corrupted configs, failed overlay migration), boot from the passive one is attempted for 3 times as well. Please note, during "failboot" the bootloader never switches active and passive bank. If all boot attempts fail, the stock bootloader automatically enters BOOTP mode for TFTP firmware flashing. Please note, in BOOTP mode the bootloader will always try flashing the uploaded firmware into bank_1 first.
  
 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, which is usually at 192.168.1.1 or 192.168.1.254 and which is branded by the provider. There are no management protocols available (e.g. telnet/ssh) other than the web UI. 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, which is usually at 192.168.1.1 or 192.168.1.254 and which is branded by the provider.

-The DANT-1 boards come with 16 MiB Flash. This chip is dual bank and able to store 2 firmware images and switch between them when the TG582n runs on stock firmware. This is done to implement a failsafe feature: if an image fails to boot (e.g. corrupted flash or failed upgrade), boot from the recovery one is attempted. +The board layout is identical to the others for this same model. The only hardware difference seems to be the flash chip: [[http://pdf1.alldatasheet.com/datasheet-pdf/view/458190/EON/EN25Q128-104FIP.html|cFeon EN25Q128-104FIP (16MiB)]]
