Linksys WAG54G2 v1.0

NOTE: The Linksys WAG54G2 is NOT version 2 of the WAG54G, it's totally different hardware.

WAG54G2 is an ADSL gateway router with 4 (available) port 10/100 ethernet switch, ADSL 2+ modem, 802.11g Wireless access point.

OpenWRT doesn't support this platform yet, but i'm going to have a go at getting it running. So, for now, this page is preliminary info.

Hardware

  • Based on the Conexant CX94610 ADSL2+ chipset with integrated wireless LAN, which is a SoC with an ARM1026EJ core.
  • Ethernet switch is an IC+ IP175 5 port, 4 ports are available on the back panel.
  • WLAN: Conexant CX94610 (Integrated), WLAN chips are covered by an aluminium screen on the board
  • 16 MB SDRAM in two 64Mb (4M x 16) Etrontech EM638165TS chips
  • 4 MB Flash is a Spansion S29GL032N ( MirrorBit, 32Mb, 110nm). Spansion was a joint venture between AMD and Fujitsu

Serial Console

Serial Console is available as a header on board (mine was covered with soldermask which needed scraping before I could solder it).

It's connector J2, at one of the corners of the board, which is 4 pins (pin 4 is marked with a "4":-

Pin 1: GND Pin 2: TXD Pin 3: VCC Pin 4: RXD

The board runs at 3.3V, but I had success with the serial console with a Maxim MAX232CPE (which is nominally 5V rated). Connect at 38,400 8N1 with no flow control.

Software

The linksys software is based on kernel 2.6.11 with plenty of patching. GPL code is available from linksys (v1.00.19_AnnexA - v1.00.19_AnnexB)

You can get root from the serial console just by pressing enter- no login needed.

Boot Loader

The boot loaded is 'PP Boot' - conexant specific. Have a look PP Boot

Information

Mandrake published patches for kernel 2.6.28 ready for OpenWRT. Can be found here: http://sourceforge.net/projects/openwag/files/WAG54G2/

This modem-router and the DG834Gv5 should be the first targets to port this SoC.
