Though the docs are not complete, the basics are there.  Start by
reading the helloworld tutorial:

http://www.gumstix.net/Software/view/Build-system-overview/Hello-world-tutorial/111.html

It will you an overview on building packages and customizing an image.
 You should also read the other sections under build system overview
to get an idea of how the whole directory structure is laid out and
where OE puts things.

Take a look build/conf/site.conf.  Modify to suit your needs.

Well,
it does provide an overview on how to make and build a single packet.
It does not provide anything about customizing an image and getting your
packets in there. I cannot find a package "gumstix-basic-image" or
a package for the kernel where I can see the it's config. (To change
the Makefile for the pxarc-kernel-module to use the oe-sources and toolchain.)

I found an "olsr"-package next to "olsrd". It looks empty and not
depend on anything. bitbake olsrd seems to work.

I found the build-system fetching and compiling xorg for a
headless-system that does not even have a text-console (only
bluetooth-sdp and ssh) while compiling gpsd.

I already reat that. It does not mention any place with a package-list for the
image.

Than you.

It's there:  look in the section called:  "Adding our package to the
rootfs image"

> I cannot find a package "gumstix-basic-image"

gumstix-basic-image is in com.gumstix.collection/packages/images

Really, the naming is pretty straightforward :-)

linux is in com.gumstix.collection/packages/linux

I'm not familiar with the pxarc module.  What is it?  If it is
generally useful I'll enable it in the build for everyone.

Oh, I must have overlooked that. Sorry.

Ah. as all the directories where named after their package-names I
only looked for something called gumstix-basic or similar.
Thanks.

It is a third-party patch found in
http://www.pabr.org/pxarc/doc/
Is uses some timers in the pxa for soft-realtime
to create a kernel-module that does software
pwm and ppm -output on gpio-pins.

I want to feed the ppm-oufput to the ppm-decoder
in an existing rc-receiver to run the paparazzi-autopilot
on the gumstix. This way I can switch from the
autopilot to normal remote-control with only one pin
and to a manual landing of the UAV piloted.
(And I only need one wire on the solder-pads of
 the gpsstix.)
The hardware ppms are interesting but I cannot use
them because I want to use the quick-capture-interface
that uses the same pins. Also it has been made clear
on this list that the higher base-frequency of the hardware-
ppms on the pxa170 makes them useless for interfacing
servos.

I already ported the paparazzi-autopilot run as a
linux-usermode-program (instead of on it's custom arm or avr
- -boards) and am conducting first flight-tests of the
airframe. I may write a package-definition for paparazzi.
But then again I may not and only modify the compiler-related
makefile-definitions in my new paparazzi-build-target and
copy that one binary by hand.

Thanks Steve!
You where most helpfull.
