Hi,
Btw: After hacking this page flipping issue, m5-rc14 basically starts
on OSK. Start takes some time, and it isn't really usable. So more or
less a "proof of concept" for 32MB systems ;). But it starts.
http://elinux.org/Android_on_OMAP
I followed the instruction and I can launch it. But unstable it goes suspend mode and never wakeup.
Yes, same to me. I thought it was related to limited memory.
If I remember correctly, after first start up, it didn't switch to
suspend. But then after each new start it went to power down.
Unfortunately, I don't remember what was different the first time :(
Which OMAP and board are you using?
So I tried to launch it with latest kernel and success with simple trick. however it's same, hanging. Why it goes hang even though
it doesn't use PM mode. :)
Anyway you can achieve it with followings.
Just to get this right: Indepenent of which kernel you use (2.6.23
with complete Android PM code or recent kernel with fake Android
below), system switches to suspend mode?
Maybe it depends on OMAP suspend configuration? Zaurus guys didn't
report anyhting of this.

First, copy required files from android kernel to latest one.
drivers/android/*
drivers/misc/lowmemorykilller/*
include/linux/android*
include/linux/binder*
include/linux/logger.h
Second, it can't compile android_power since the APIs are changed.
So you register fake alarm to logger [2].
Finally launches it.
I hope it's helpful you.
Thank you,
Kyungmin Park
