The following table lists the functional modules of the KWGR614 router and the source and versions of the different modules. More information on these functional modules can be obtained directly from the source of the packages.

KWGR Open Source Guide (Rev 2.0) Provided below is an example schematic using MAX3232, the RS-232 Line Driver/Receiver from Texas Instruments (TI), to make a console board. (Datasheet of the MAX3232 can be found on TI web site at The DB9 (Male) connector is wired as a DCE (think of this as a peripheral serial port), and can be connected directly to the serial port on a host PC. This gives you access to the built-in serial console on the router (using the protocol of 38400bps, 8 data bits, none parity, 1 stop bit, without flow control). Connect the console board to the pin header (J303) on the router board. KWGR Open Source Guide (Rev 2.0) The pin-out of J303 on the KWGR614 board is as follows: Pin 1: VDDH (3.3V) Pin 2: TxD Pin 3: RxD Pin 4: GND (Ground) There are 3rd party vendors who provide compatible console boards, such us the AD233AK/AD233BK RS232 adapter kits at: Make sure the adapter board is connected correctly to the corresponding pins of J303 on the router board. KWGR Open Source Guide (Rev 2.0) Source Code and Executable The following section of the document highlights the steps and procedures that are required to download the source code, install the toolchain, compile and link the existing source code and develop the user applications for the KWGR614 Router. Suse Linux 10.1 was used for development throughout this guide. Note: The KWGR614 firmware had been built successfully on the following Linux OS platforms - Redhat 9.0/8.x - Fedora 5 - SuSE Linux 10.1 1. Download the complete archive from Netgear OSC web site (and unpack KWGR614_V1.0.1_10.17WW_gpl_package.zip Note: V1.0.1_10.17 is the firmware version number. WW denotes Worldwide version. Other versions are available e.g NA for North America. Apply the correct file name where appropriate, if you download a different version. 2. unzip KWGR614_V1.0.1_10.17WW_gpl_package.zip Unzip will result in three files: KWGR614_README.txt (The Opensource User Guide) KWGR614_V1.0.1_10.17WW_src.tar.bz2 toolchain_mips_20050831.tar.bz2 3. Unpack the Source code. tar –xvf KWGR614_V1.0.1_10.17WW_src.tar.bz2 This will create a sub directory KWGR614_xxx/. xxx -> V1.0.1_10.17WW (xxx denotes the version number) The Directory has a number of useful documents that we recommend to read before proceeding. Useful Documents - /vendors/Documentation/KWGR614_README.txt - /SOURCE - /README - /Documentation/Adding-User-Apps-HOWTO - /Documentation/Addid-Platforms-HOWTO 4. Install the Tool chain in the root Directory # cd / # mkdir uclibc # cd uclibc # tar jxvf toolchain_mips_20050831.tar.bz2 # mv toolchain_mips.pv.0831 toolchain_mips Note: Root user permissions may be required to create the uclibc directory and install the toolchain into the root directory of the filesystem. 5. Compile Change working directory to KWGR614_xxx/ a. Type "make menuconfig", and customize your kernel config options. - Target Platform Selection ---> [ * ] Customize Kernel Settings (NEW) - Exit KWGR Open Source Guide (Rev 2.0) -Exit -Save configuration? yes -Exit -Save configuration? yes Note: If you are building runtime image for the first time, be sure to save the configuration when leaving "make menuconfig", even if no change is made to default settings. b. Type "make dep" c. (Optional) If you need to customize busybox, goto KWGR614_xxx/user/busybox/, and type "make menuconfig" to select user level application you need. Then go back to KWGR614_xxx/, and type "make dep" again. ...
