Some questions on configuring OE

Some questions on configuring OE

[Dr. H. Nikolaus Schaller]

I am trying to use OE and the MokoMakefile to build an OABI OpenMoko  
version for the Neo GTA01 - and for the Acer n30 PDA.

So far I succeeded in building everything without errors on a Debian  
Etch machine but it does not run.
The Neo does not complete booting to X11 and the last message  on the  
boot screen is

mcblk0: mmc0:e624 SU512 495488KiB
  mmcblk0: p1

Pressing the power key produces messages like:
pcf50606_irq:entering(irq=53, pcf=c0555800): scheduling work
pcf50606_work: INT=0x42 INT2=0x00 INT3=0x00:ONKEYF SECOND
pcf50606_irq:entering(irq=53, pcf=c0555800): scheduling work
pcf50606_work: INT=0x01 INT2=0x00 INT3=0x00:ONKEYR

but nothing else... The AUX button produces a ^@ on the console.

Before that there are some messages about initializing Bluetooth, CDC  
Ethernet, mouting the .jffs2 as root but no error messages.

The Acer n30 hangs in the X11 touchscreen calibration because the  
touch does not work. And the power management is worse than the one  
in the old Letux kernel. So I suspect that not all patches are  
applied when using the default machine/acern30.conf of OE.

What I need is some help how to configure the build system properly  
(unfortunately, chapters 7&8 of  http://www.uv-ac.de/openembedded/ 
openembedded-7.html are not completed).

Questions:
1. I could not find out if and which of the Letux n30 patches have  
been included to the MACHINE = "acern30" so far
2. if not, I have some patch files from the Letux project - but how  
and where should I configure those?
3. What do I need to change to compile OpenMoko for OABI so that it  
really boots?

Many thanks for any hints how to proceed,
Nikolaus

If the touchscreen issue is not a kernel problem check your /etc/X11/Xserver
script (from xserver-(kdrive-)common package) if it has support for your device.

The acern30.conf defines that the linux_2.6.14.bb is used. So unless something
else overrides this (your local.conf or the distro maybe) you will get 2.6.14
which applies a lot of patches for the n30. You would have to check
linux_2.6.14.bb what these patches are and where they come from.

Just add them to the linux kernel bb. The default linux_2.6.14.bb is a good
example how additional machine dependent patches are applied.

I don't think there are special needs for OpenMoko, its a setting in the distro
definition you use. angstrom-2008.1-legacy.conf should contain the bits doing
the right thing.
