Both are Tegra2 devices
Both are using the same Wifi chips
Both are GSM/HSPA devices
Plan of action:
Get Xoom kernel for 2.6.32 (same level as the kernel we've got for Atrix)
Diff the two for platform specific changes
Get Xoom kernel for 4.1.2 release (http://www.xda-developers.com/android/motorola-xoom-gets-stock-rooted-android-4-1-2/)
Put in platform specific changes learned from diff
Then you should have a binary compatible Atrix-fied Xoom kernel, running on the Atrix. Which enables you to
Use Xoom hardware acceleration
Have a propper Project Butter experience
Have a kernel that doesn't run on the compatibility mode of bionic libraries
A more modern and mature Linux kernel (and libs)

Its a good plan, but woudnt the architecture be slightly different?
I really don't know what it means, but it was said very often in the forums:
Xoom = SoC T20
Atrix = SoC AP20h
But I hope that you can do some magic :silly:
Have you actually started this process or is it just a plan you hope will work?

it's not only the cpu and antenna...there is also the camera,fingerprint and imo the resolution of the screen is also important...
so this kernel cannot be used...only some parts of it mabe
If is works, It will be a great dev but
is it possible?

Ok - some history:
I've worked at a mining communications/safety company Becker Mining Systems, for their R&D firm Becker R&D in South Africa.
We've developed an Android VOIP phone for to be used in mining (hazardous, please-don't-make-a-spark) environments. We've succeded, but then Germany practically canned their colleries (hug-a-tree-don't-kill-johnny-polar-bear) - resulting us to stop development 2 months before manufacturing (literally only had to make the moulds). Sigh - the collery overseers DSK was the contracting client.
My job was to get Android running on this Freescale iMX31 based platform. I did the kernel + Wifi + Android + VOIP and a bit of the UI.
Plan of action:
/arch/arm/ is the first point to go looking for things in the kernel. In this case, we'll be looking for /arch/arm/mach-tegra/, this is where all the platform specifics will hide away.
Compare board-olympus.c and board-stingray.c (+ board-olympus.h and board-stingray.h). Look for similarities, look for differences. These are the glue points - in this .c files the startup / fixup / powerup of the platform starts off. See it as the void main(void) file for the platforms.
Adapt the board-stingray.c in such a way that it starts up on the Atrix
After kernel start up, get the peripherals running. This includes UARTS (USB the most common, and debug), SPI (chats to other peripherals), MMC (chats to the WiFi/BT module) and also the screen.
Merge in libraries - we'll probably using the Atrix radio driver file, but the rest (Wifi, OpenGL libs) from the Xoom
If all of this doesn't make sense to you, please press the thank you button and refrain from commenting on this feed
Hmmm... yeah you are the right person for this job :laugh::good: :highfive:
I wish you to succeed, you would make lot of people to be really happy !
If you need testers, i'll be right there.
Jokersax already said its possible, in fact, he was using some Xoom binaries that he ported, but he also said that it required a MASSIVE amount of coding, time and skills to get it done.
Hope you can accomplish this dude! Good luck!

yeah well those didn't really make a difference... and we have the libs, only need a supporting kernel.

Indeed, he showed that it was possible.
It might help when nVidia goes opensource with the Tegra drivers, but so far I haven't seen enough details on that to be encouraged yet. I suspect that what we'll see will be either code dropped into nouveau or a separate driver set rather than nVidia opening up their proprietary drivers.
mvniekerk, please join Atrix Re-Birth Project.
We already have libs for Atrix, two leaked rom, closed kernel, useful CM 10 (I'm using it right now), great developers (Epinter, MMontuori, TPoint75...)
With your knowledge and enthusiasm we could go even further and faster.
This can be tested, it's very simple, dd the xoom boot partition to a file, then flash out back to the Atrix. If it passes the boot logo, there is hope...

Surprisingly we dont yet have monitor mode, airsniffing, or aircracking capabilities within android. The drivers are open source and require some modifications for these features to be taken advantage of. How hard would it be for the dev's here to rewrite the wireless drivers to enable monitor mode? Also wouldnt it be neat to have a android/debian mix'ed rom where we can apt-get things right to the phone instead of a chrooted environment? It would be cool to see some more hacking at this and other things. Let's unleash the wireless functionality of these devices.
It would be cool to get aircrack working on our devices, people with iphones got monitor mode working, just not injection. From what I have seen injection is possible for us, so whats keeping us back from unleashing it?
Also Metasploit Mobile would be a killer addition to android if it only requires python
Ok It seems monitor mode is possible on the bcm4329 chipset which is in our devices and needs a rewrite

For once it will allow the phone to act as a packet sniffer. Pretty useful if you are into monitoring network activities
I'd love to see a port for our phones.
Yes, this is exactly why I made a thread asking for help getting Debian running on our phones
BTW which someone already has done and has a how-to guide here http://blog.coralic.nl/2010/08/17/ubuntu-on-samsung-galaxy-s-android/
Don't want to lead anyone off with that link, just wanted to plug that in in case anyone else wanted to try it.
But truly this is where the true FUN is, you know. I would love to use a wireshark like type app or aircrack for that matter. I would die to have apt-get built in to the OS.
I have actually been considering working on a project like this for a few weeks. I'll see what's involved next week when I'm on vacation. Ultimately I was hoping to port something similar to kismet to the Galaxy S phone with nice GUI for wireless network penetration testing.
If anyone else has systems development experience and wants to work with me on this, PM me and we can get in touch.

It would be best to get in contact with HD MOORE of Metasploit or the authors of this software and request for a port.

Metasploit, if it only requires Python, is probably trivial to port to Android. I'm personally interested in working on Aircrack, Monitor Mode, and Packet Injection. These are very different projects and perhaps should be two separate threads.

Does anybody know about any kernel modules allowing to mount a CD ROM drive?
Lapdock and webdock have USB ports however to the best of my knowledge Atrix does not contain a kernel module to mound CDROM/DVD volumes.
Here is my /proc/config.gz:
Code:
#
# CD-ROM/DVD Filesystems

# CONFIG_ISO9660_FS is not set
# CONFIG_UDF_FS is not set
Is anybody aware of such CD ROM kernel module or could build one?
I can't believe nobody ever raised this issue before.....
Why
In all honesty, android probably does not include the codecs necessary to decode CDROM music and most apps are distributed over the internet so what use would a CDROM drive be?

Why not? CDROM/DVDROM not being useful? Atrix webtop has not one but two USB ports which can mount mass storage but not CD/DVD. Thats a limitation.

It meets the specs, not sure about USB host but everything else. I imagine you could use bluetooth for keyboard/mouse as well. I wonder if it will be possible to get something like this working on the Droid 3.

Silber said Ubuntu for Android would be released under an open source license, but that Canonical expects it to mostly be pre-installed on specific hardware.
"We'll want to optimise for certain hardware profiles and chips," she said. "It simply wouldn't be the same experience on a downloaded install."

Source: http://www.pcpro.co.uk/news/373024/canonical-puts-ubuntu-on-android-smartphones
So it will be open source and not OEM only. I was thinking it would be open source since its Ubuntu but you can never be sure.
As far as optimizing it for hardware, hopefully the fact that the phone they demoed it on has the same exact OMAP/PowerVR SoC that is on the Droid 3 means the source will be most optimized for that hardware. In the demo it looked like a nearly finished project.

I'm hoping it would be possible to get it working with just HDMI output and no dock. I don't know if the Droid 3 supports USB OTG host mode, but it does allow bluetooth keyboards and mice simultaneously so hopefully that would be an option.
The Droid 3 works with the lapdock/webtop hardware wise according to this youtube video below.

They also said it would come preinstalled on some phones, because it needs some optimization to run smoothly. Read that on The Verge

He made it sound somewhat like Android source is, it will be available but the average user can't just install it on a device and expect it to work. Hopefully the devs here can make it work. The biggest limitation for us is going to be only 512MB of RAM, besides for that the demo phone has the same hardware as the Droid 3. It may not be a multitasking device, but I imagine things could be done on the Linux side to cut memory usage, possibly even switching to a lighter Ubuntu forked distro. It would still be useful as is for simple web browsing, a real office suite (LibreOffice), a real media player (VLC), etc.
Seriously thinking about getting the lapdock, since the Atrix one is very cheap and easily modified to work with the Droid 4.
Only problem is I don't want to go back to the stock ROM. Has anyone gotten Webtop to work on one of the ICS based CM or AOKP ports?
Also how much control do you get in Webtop. I understand it's basically Ubuntu, but can you install new packages or build your own from source. Is there hardware access to the GPU?
If your on an ICS leak webtop is 3.0, which means it is just tablet ui and is no longer a "separate" system.

Oh, that's a bit useless
I was looking forward to the idea of being able to boot into Ubuntu and compile full fat apps to run there.

not at the moment, because CM9 and AOKP still don't have support for HDMI-out.

That Ubuntu for Android is interesting, I was a little disappointed that webtop on ICS is just Android tablet UI rather than Ubuntu, however it is awesome that if you just use an HDMI cable the phone touchscreen changes into a touchpad!
I wonder how they are getting away with not publishing the source? As soon as a handset turns up for sale with Ubuntu on it, surely the source is going to have to come out or they will be violating the GPL, or is Ubuntu full of propriety closed source crap these days? (It's been a while since I used Linux as a desktop OS, and it was always Debian. Ubuntu didn't exist then)
On a related note, has anyone found a micro-HDMI cable that is actually capable of running at 1080p without corruption and sparklies. I have tried two and both were rubbish.
I got the motorola one from amazon, and it works flawlessly. I also got one from dealsextreme.com, which was considerably cheaper and free shipping, but they're services can be a bit shoddy at time, but I haven't had any big issues with them, and the cord quality is fine, no issues that I can see on my 1080p tv.

I tried a Motorola one... it was better in that you could actually see the 1080p display, but still flashed and corrupted.
I know my monitor is more sensitive than most to poor quality HDMI devices (most notably the PS3), so I guess I'll just have to look for a fancy one, or a tiny adaptor to use with an existing good cable.
For those interested: I found a way to install Ubuntu on my ICS Droid 4. It comes with Firefox and LibreOffice, some options like installing new apps seem a bit limited (maybe not in the donate version?), but I didn't go into too much detail.
While it's probably not as integrated as the original WebTop was, it might be more flexible in terms of settings/applications. The way to access it is basically to start it via Terminal, then (Android) VNC to view / interact with the desktop.
The link to the free version is: https://play.google.com/store/apps/details?id=com.zpwebsites.linuxonandroid
There's also some donation keys available, not sure what features they add. For me, tinkering around with it for 5 minutes is probably all I need it for, and the image is 3.5 GB so I'll probably remove it soon. Still, awesome that it works!

If you download the latest raspbian, it should have overclocking as an option in setup (when installing)
I think for other distro's they have distro specifc configs, what distro are you trying to install / overclock?
Yea most builds all have it integrated via "raspi config" where you can pick fast, turbo, etc. If your new with it go that route. Otherwise any distribution can be manually overclocked in the config file on the root partition. If on windows make sure you use something like notepad+ as you will need to keep the file correct with utf8. Go to the main website and under forums, then power users, the first thread is a good tutorial as well as good settings for you to try. For instance on model b it had been found that those who got Samsung ram rather than hiainx can overclock it higher.
