IPv6 On Gumstix

From Matt's Wiki

This page describes the process of getting IPv6 configured and working on the gumstix platform. (All paths listed are relative to the gumstix buildroot directory)

 * Compile IPv6 support into the Linux kernel being used.
   * cd build_arm_nofpu/linux-2.6.20gum/
   * make ARCH=arm CROSS_COMPILE=`pwd`/../staging_dir/bin/arm-linux- menuconfig
     * Configure all IPv6 Options you need
   * make ARCH=arm CROSS_COMPILE=`pwd`/../staging_dir/bin/arm-linux-
 * Set all the neccessary busybox tools to be compiled at the final make by editing the busybox config file ~target/device/Gumstix/basix-connex/busybox.config
   * The following options need to be set
     * CONFIG_FEATURE_IPV6=y
     * CONFIG_FEATURE_IFUPDOWN_IPV6=y
   * Some optional but useful features I enabled
     * CONFIG_PING6=y
     * CONFIG_FEATURE_FANCY_PING6=y
   * The version of busybox that comes with the gumstix buildroot is quite old and trying to use the daily snapshot didn't work for me so I also compiled a newer (1.4.1) version seperately and just copied that over, the newer versions have a lot of fixes for IPv6 in so it is a good idea to do this.
 * Setup uClibc to support IPv6
   * cd toolchain_build_arm_nofpu/uClibc
   * make ARCH=arm CROSS_COMPILE=../../build_arm_nofpu/staging_dir/bin/arm-linux- menuconfig
     * Enable IPv6 support under the Networking Support menu
   * Exit menuconfig
   * make ARCH=arm CROSS_COMPILE=../../build_arm_nofpu/staging_dir/bin/arm-linux-
 * Make the image
   * In the buildroot directory run 'make' and this should then build an IPv6 capable image, flash the Gumstix and you're off....
