I am hoping Cocoboot will allow us to boot the android kernel.  We
will need to compile the kernel for the hardware on Treo.

First try should be a very simple kernel just to see if it will boot.
Then we can start adding stuff from there. (I am hoping)

My issues are getting to the bootloader and flashing the phones.

P.S. The 800w will probably be easier to hack them you think. ;-)

FYI, I've successfully compiled a kernel using the sources from
Hack&Dev and Cocobooted it on a Treo 650.

But then I lack the knowledge to integrate the Hack&Dev and Android
sources and compile a working kernel. Tried quite a few different ways
but none worked.

Somehow, I got to "How are you gentlemen" once.

Anyway, I don't have plans to work further on it given the hardware
limits of Treo 650.

Cheers.

The nice guys over Hack&Dev is working to push upstream their work
into the mainstream kernel.

So when it's done, and the complete source of Android is released,
maybe I will try to do it again.

(Of course, my preferred way is to download a working kernel and the
userspace, and use it right away... : )

Still, I'm doubtful if the 650 can handle it... Newer models are
better spec-ed but then kernel support is an issue.

When is the source being released anyways?  Seems like it is taking
forever.

I have no problems using my Centro as a test phone if we are playing
with Cocoboot.

I have a one quick question

How do you guys deal with Dalvik virtual machine? If you just port the
kernel image to the real device, without porting the dalvik which
seems to be compiled by non-standard-libc, you should not be able to
run any application wrote by yourself, right?

I believe a good starting point would be to compile a Linux 2.6.23
kernel for the Treo's ARM architecture.

From what I am reading, Android will work on any 2.6.23 kernel.

We should be able to move quickly from there. :)

Android is based on 2.6.25.

The recommended tree for 650 over Hack&Dev is 2.6.27 (http://
git.hackndev.com/?p=linux-2.6;a=summary). Not sure about the other
devices.

Anyway, after reading the "releases features" (http://
source.android.com/release-features), my hope is greatly dash... : )

"The platform requires a minimum of 128 MB of RAM and 256 MB of Flash
memory."

I still have hope!  64MB/64MB should be enough! (650 probably won't
cut it) :(

You mentioned in a previous post you booted your Treo to Linux with
Cocoboot.  What Linux kernel did you use?

Thanks

Centro.  Looks like they are getting close.

IIRC it's a 2.6.21 snapshot from http://git.hackndev.com/?p=linux-hnd;a=summary
*without* any Android-specific patches.

In case you're interested, you may get my zImage and cocoboot.conf
from http://ifile.it/2msu7on

FYI, I formatted the SD card into 2 partitions - The first was a FAT16
for the kernel and cocoboot.conf. The second was an ext2 containing
the Android file system downloaded from somewhere.

Then tried to boot using the method mentioned at
http://elinux.org/Android_on_OMAP#Android_root_file_system

Or similarly http://download.enlightenment.org/misc/Illume/Treo-650/2008-10-12/README

And of course, Android failed to start. : )

In case you would like to do it yourself, you may like to setup the
environment for compiling the kernel (i.e. a Linux distro and ARM
toolchains...), and get a kernel (without the Android patches)
successfully compiled and booted on your device first.

Cheers and have a nice weekend!

I downloaded your image and tried booting it on my Centro.  It loads
the image, says "OK" then freezes.

Even though the 650 and Centro both use the PXA270, the memory is
different.

Here is the output from Cocoboots "info" menu for my Sprint Centro:

Machine: D062
CPU ID: 0x69054117
CPU: Intel PXA27x

Memory:
RAM base: 0xa0000000
Size: 32mb
Phys TTB: 0xa1ffc000
Virt TTB: 0xa1ffc000

I am using Cocoboot 0.5.2 which recognizes the Centro correctly.

I need to find my old 650.  It's laying around somewhere.

The dalvik source code is available, and there are less than a
handfull of files that will need to be ported (as I looked so far).
For a device with armv5, or with the same instruction mnemonics and
semantics, no port effort will be needed.
For other platforms, one should take a look on all of the .S files
(277 files), and three files that have inline asm:

./vm/mterp/out/InterpC-armv5.c
./vm/mterp/armv5/debug.c
./vm/Atomic.h

The first two have only declarations of register for certain variables.

Some collateral changes will be needed for platforms that are not
RISC-like (with fewer registers, like Intel's Atom).

But I have a question: any effort into porting dalvik to non-embedded
non-RISC linux?

Great news about the porting.  The 650-Centro all have armv5 cpus.
The Treo Pro and Treo 800w use armv6 cpus.  I am guessing we are in
the same boat with the Libraries?

I found my 650.  Using the kernel Lo Yuk Fai provided along with
Cocoboot, I was able boot.  I get a kernel panic when it tries to load
the file system, because I haven't created a file system on the second
parition yet.  (I am only using 1 partition)

I am trying to get a kernel booting on newer Treo devices with
Cocoboot.  Stay tuned...

Cheers!

I think we need someone knowledgeable in hacking the kernel to step in
in order to get it goes further... : )

Can't we just work off the kernel being used over at Hack&Dev?  I was
just reading they got the Centro and 700p booting using the 680
kernel.

We can build upon this kernel to add support for the various
hardware.  If the display and keyboard are working in the current
release, it may be enough to start Android.

Someone please correct me if I am wrong, but if we get a working Linux
kernel, we should be able to use an already-ARM-compiled Android
system, living on an ext3fs partition. (SDcard)
