Introduction
What is OpenWGT? OpenWGT is a Linux distribution designed to run on Netgear's WGT634U Wireless Media Routers. OpenWGT intents to be compatible to OpenWRT (a distribution for the Linksys WRT54G(S) broadband router).
This OpenWRT compatibility will be reached by compatibility in:
- Init process layout
- NVRAM layout
- ipkg management
- flash partition layout
Advantages
Why don't use the distributed Linux system?
- booting needs lots of time (> 2 minutes)
- it's hard to install own programs
- bad fallback strategy (if modifications fail)
Overview
OpenWGT consists of two parts:
- Linux kernel (2.4 or 2.6)
- Root file system
Installation
WARNING: The installation of OpenWGT is heavily under construction. So we recommend to continue the following steps only if you have a serial console for your Netgear WGT634U.
There are 2 possibilities to install the OpenWGT Linux distribution:
- self-compile from sources (using the standarized development environment - WRTSDE)
- use the OpenWGT web installer (alpha stadium) - You will need an online connection during the whole installation process!
Compiling OpenWGT from sources
NOTE: Instead of compile OpenWGT for your own or using the web-installer, you can download the binaries we are using for our Netgear routers. You can get it from: http://sar.informatik.hu-berlin.de/research/roofnet/openwgt/binary/ See below how to install the binaries.
For self-compilation you will need:
- a toolchain for cross-compiling, since the Netgear WGT634U contains a Mipsel CPU.
- the SAR OpenWGT sources (these are an old snapshot from the OpenWRT project)
- sources of the Linux kernel from netgear
You can also download a complete OpenWGT construction kit from http://sar.informatik.hu-berlin.de/.../
OpenWGT web installer
We provide a web-installer to install then OpenWGT distribution, but note that the installer is under construction yet (alpha stadium).
web-installer TODO list:
- split the installer script (to show intermediate results)
Booting OpenWGT
TODO: Description of:
- boot from flash
- boot via network (TFTP/NFS)
