Which kernel (2.6.x, x == ?)  do you use on N810? If I remember 
correctly, with N810 people use an older kernel than the one coming 
with Android SDK.

Can you send us the complete segementation fault output?

Current linux-omap's head has all the necessary pieces to get n810
working. Touchscreen, keypad, ambient light sensor, led, usb, everything
is there.

Maybe it's easier to get android's patches on top of current linux-omap
?

but anyway, it seems that you don't have android's fs support on your
kernel... Are you getting a "VFS: could not mount root" or something
like that?

You forget power management. It should partially be redone together with
the omap3 work, but stuff like DVFS has a quite different implementation
due to the different capabilities of the implementations.

For any practical case where the device has to be used as mobile
platform I think it's not an option to use the current l-o.

Hopefully it will be in the future.

For some experiments with android is good enough.

since you have a both TRMs, you can check it by yourself: DMA stalling

in case you haven't noticed, there's some major rework ongoing for power
management

as i said, hopefully in the future also n810 will benefit from it

I also wonder if any kernel to userspace interface has changed since we
released the FW: that could compromise the execution of system services.

It would be probably good to check if any "obsolete interface" option
has to be enabled when configuring the new kernel.

Note that my native ALSA implementation doesn't work with our OS200x
because it's using GStreamer - DSP GW - DSP centric audio architecture
[1]. However, I think it should be possible to build GStreamer to run on
top of my work since x86 SDK build is using native ALSA and OSS drivers.

But I assume Android folks doesn't have this restriction :-)

I've merged Jarkko's asoc patch to linux-omap for testing. Have not
gotten any sound out of it on my n810 though.. Maybe some alsamixer
settings issue?

Kalle, do you have any tips on getting WLAN to work on n8x0?

Don't know if there's anything new there to you, but I posted some
info on getting things to work with current linux-omap kernel at:

http://www.muru.com/linux/n8x0/

This was the show-stopper for me.  When I last got things hobbling
along on n8x0, the binary-only wlan module was incompatible with
newer kernels than 2.6.21 (changes in some network data structures).

The newer android builds expect 2.6.24 or more recent.  I'm hoping
that Nokia will release a newer build of the wlan module for 2.6.24
at some point.  That'd be a big motivator for me to spend time hacking
on the platform again.

The other thing I'd like to sort out is how to interact with the
battery charging and status without needing proprietary userspace
code.  Probably a lot easier to reverse engineer than the wlan driver
at least.

That's exactly the problem. I have written something about it here:

https://garage.maemo.org/pipermail/cx3110x-devel/2007-December/000007.html

Currently there's nothing I can do to resolve the issue,
unfortunately.

Just did a quick diff between v2.6.21 and v2.6.24 and the skbuff changes
are pretty daunting.  Doesn't look like there's an easy hack here...

> Currently there's nothing I can do to resolve the issue, unfortunately.

Pity.  It'd be nice to get newer kernels running on the n8x0 -- it's
nice hardware.

Trust me, I share the pain. If a solution comes up, I'll let you know.

It's also a good idea to follow cx3110x-devel:

Have a look to the section

-- cut --
...

In the end I think what would be realistically possible ...
is that Nokia provides one person whose sole task is to support the
community by mantaining the closed code and providing new binaries that
link against recent libraries. The community would still be able to set
the direction for the development and ask for updates, so that these
closed areas would not hold back work done in the open part. Which is
the majority.

Unfortunately no. It's not a big task, but proprietary umac.ko is the
biggest problem. It needs to be recompiled.

Mmh, there are some reports on this list with similar SIGSEGV:

http://marc.info/?l=linux-omap&m=120393103218574&w=2
http://marc.info/?l=linux-omap&m=120400327301855&w=2
http://marc.info/?l=linux-omap&m=120834030203728&w=2

But It doesn't look like the archives have a detailed solution for 
this. Seems that changing some parameters (e.g. switching to other 
binder driver, SDK etc.) made the error go away.

I'm CCing Anil and colorant, maybe they remember what helped.

Re: Android on N810 File System Problem

[Jonathan Herriott]

I had it confirmed in another thread that the issue is that the local
filesystem for the N810 is jffs, which is unsupported and I need to
install it on an mini SD card with ext2/ext3 on it.

Re: Android on N810 File System Problem

I think what you're seeing here is the property service in init
failing to create and mmap it's arena, which it tries to do in /,
which in our world is initramfs.  The android init/boot model is a
little different in that we don't pivot over to a root filesystem,
we mount the system, data, etc partitions under the ramfs on /

You might be able to hack around this by editing the string
"/system_properties" to "/tmp/em_properties" or something like
that, assuming you have tmpfs mounted on /tmp.

We're trying to use the standard kernel/driver interfaces when possible,
but for things that may have a good deal of variation in implementation,
we're looking to provide a very thin "hardware interface library" layer
to adapt between the bottom of the userspace stack and the drivers or
whatnot for specific hardware platforms.  

We'll continue to adopt standardized kernel solutions as they become
available -- We're now using the power supply framework in 2.6.24 for
monitoring battery/charge state (post M5 SDK -- it'll be in the next 
release), for example.

Hi Anil,

I had reported some Power management behavior after bringing up android
on 2430. Here is the thread .
http://marc.info/?l=linux-omap&m=120948254632401&w=2

Basically the Android GUI comes up and transitions from Active to Sleep
mode happens properly for the first 2 times.(by pressing the up and down
keys).
But the third time ,it never comes from the deep sleep mode. 

Do you any idea about this ?Any inputs on this is highly appreciated.

Regards,
Shivananda
