For this source code release, two toolchains are required:

1. A MIPS little-endian toolchain. For example, hndtools-mipsel-linux-3.0

• from Broadcom Corporation. This toolchain is used to compile uClibc and Linux kernel.

2. A MIPS little-endian toolchain compiled with C++ and uClibc support.

• This toolchain is used to compile linuxigd. CPP_STAGING_DIR in Makefile must be modified to indicate the exact path of this toolchain.

Then, a "make" should suffice to build all GPL components of WGT634U.

USB

This device has a USB2.0 port.

CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI=m
CONFIG_USB_STORAGE=m

By default, it wants to mount a usb mass_storage device (/dev/sda) on /share/partition1

As you know, this allows one to add an external HDD/USB keychain, etc. [:GPS], BlueTooth?

Serial

There are actually 2 serial headers on the board. For more information on adding a port, see http://www.nslu2-linux.org/wiki/HowTo/AddASerialPort

CONFIG_CMDLINE="root=/dev/ram console=ttyS1,115200"

http://www.personaltelco.net/albums/NetgearWGT634U/dscn3058.thumb.jpg BR

I simply added a serial cable to the outer-most header and booted the device. The bootlog (firmware 1.0.0.11?) can be found [http://personaltelco.net/~jason/wgt634u_bootlog here]. Another log from the latest version which has a number of fixes, including the addition of [http://atheros.com/pt/atheros_XR_whitepaper.pdf Atheros XR] and AR(Addaptive Radio) is located [http://personaltelco.net/~jason/wgt634u_bootlog-1.4.1.9 here].

Battery Power

Measured battery usage: 0.38Amps @12VDC BR Input 12VDC. I've been testing a 12V 4 amp-hour sealed lead-calcium (leadacid) battery. After 20 hours of charging with a 12v 200mAmp charger, the wgt634u was connected to the battery.--DonPark
