OpenMoko + Gentoo [0]
Me and some friends of mine received our
OpenMoko FreeRunner
some days ago. Since then I have used some hours playing around with it. Short
explained, it is an open sourced linux powered phone where the software is not
yet finished. The phone is contains two accelerometers, bluetooth support, a
GPS, micro SD card reader, wlan, usb-plug , a large touch-sensitiv screen and
an ARM SOC.
Setting up network
I assume that my system had the needed drivers loaded already, so if I want to
do this by hand I do as root (after pluging in the phone)
root@laptop ~ # ifconfig usb0 192.168.0.200 netmask 255.255.255.192 up
root@laptop ~ # echo 1 > /proc/sys/net/ipv4/ip_forward
root@laptop ~ # iptables -t nat -A POSTROUTING -j MASQUERADE
root@laptop ~ # echo 1 > /proc/sys/net/ipv4/ip_forward
root@laptop ~ # iptables -t nat -A POSTROUTING -j MASQUERADE
Permanent stuff is much more distro-specific to note here.
Setting up the prebuilt toolchain
First I thought that I wanted to build everything myself, but after spending
some hours with that, I figured that there really wasn't any reason for that,
since I could download a ready-made toolchain for x86 that didn't depend on
any wierd preinstalled libraries of speific versions; how neat.

So each time I now want to use the toolchain I do this in the shell
stian@laptop ~ $ . /usr/local/openmoko/arm/setup-env
Compiling your own kernel
First I got lost with the kernel-patch-set that was present in the monotone
repository until I discovered that openmoko has their own git repository
(see here for info).
Also, please note the need for unset LDFLAGS when compiling the kernel-tree!.
So here we go:
stian@laptop ~ $ . /usr/local/openmoko/arm/setup-env
stian@laptop ~ $ unset LDFLAGS
stian@laptop ~ $ cd moko/sources
stian@laptop ~/moko/sources $ git clone git://git.openmoko.org/git/kernel.git linux-2.6
