[WIP] Ubuntu netbook 10.10 porting

Hi !
I'm actually porting/playing with ubuntu on my Galaxy S. The goal would be to boot ubuntu "natively" from the ubuntu initramfs, but since i was unable to get a working framebuffer output on kernel boot (if someone have a solution for this, it would really help me), i'm using a chrooted environment for now. Some guys already had ubuntu to run on the Galaxy S in a chrooted environment, but the android UI was still running (using a lot of memory) and we had to use VNC to experience the ubuntu desktop. With this version, X is using the s3cfb framebuffer and fbdev driver to draw to the screen. I have also modified a Xorg input driver (plpevtch) to have a preliminary touch screen support. Since we still run it after the android services initializations, ubuntu will use the current connection (wifi, 3G).
If someone want's to play/help/try this stuff, here is the procedure i'v done for now :
Requirements :
- A Linux computer ( tested on ubuntu 10.10 )
- Galaxy S i9000 running an android kernel with ext2 support ( tested with Universal lagfix kernel )
- root (provided with the previous kernel i think)
- busybox (market)
- sdcard 2GB at least, primary partition formated to ext2 (play with the scripts to change to fat or ext4 etc)
- I think that's all
Download :
Download the attached package and extract it, this one contains the required scripts to download/patch ubuntu, prepare the sdcard, and stat/stop ubuntu.
Usage :
create.sh :
usage : create.sh /path/to/my/ext2/sdcard
This script will download the ubuntu netbook 10.10 compressed image for arm, decompress it, mount it then copy the filesystem to a specified path (should be an ext2 formated partition on the sdcard, and be the first partition on the sdcard ( /dev/mmcblkXp1 ).
Should be run first, one time ...
start.sh :
usage : start.sh
This script run "droid_ubuntu_init.sh" on the phone, which stop the android interface, mount the sdcard, prepare the chrooted environment and start a chrooted session (chroot_init.sh, which simulate a "daemon" to allow services to run in the background and start the ubuntu desktop.
Should be run everytime you wants to start ubuntu.
update.sh :
usage : update.sh
At the first "boot", ubuntu desktop (X) will not work, we have to update the distribution. To do so, run "start.sh" (if not already done) to start ubuntu, then run this script. It will update ubuntu (you should really use a wifi connection to do so), and X should then work. It will also install an ssh server. This will take a long time
Should be run one time.
====== Notes =====
If you want to run some "services", you should edit the file "scripts/chroot_init.sh" and add your service here (after the ssh service for example).
The package contains the "patch" applied to the ubuntu rootfs, and the sources of the modified touchscreen xorg input driver.
I did not work on a "stop" script yet, you'll have to reboot the phone if you want the android UI back.
It's really a work in progress, nothing really usable for now.

This is realy cool thumbs up
Il defently start looking at this at first possible time slice.

Hi, where is the script ?
I would love to see Ubuntu running in native mode like it did on my former HD2 (witch, btw, i still think it's the best smartphone ever, Galaxy S - no were near).

Won't that be primarily because of the HUGE amount of development for it?

What about trying with a lightweight disto like puppy linux? last one uses lucid lynx package and it can run in ram (so very light).
Also maybe you can make some kind of "boot menu" using recovery mode:
in recovery mode, android is not started so if we add an entry to to recovery to run the start script on the sd from there it should be what you are looking for.

The only big problem i see for me to port ubuntu or anything else natively is a way to debug the boot process. Unfortunately, i was unable to get the kernel framebuffer to work, i would really need some help on this. For now it work great enough in a chrooted env to port some drivers etc. Anyone ? Else yes i'm using a custom rootfs to debug the kernel/drivers/rootfs.

Let's hope i find the time to try this tonight, while booting from a Ubuntu livecd

Oups, i did forget to attach the files. .. Will do so tomorow.
Has anyone worked on "really" porting another distro, done some work on kernel drivers? Actually it seems the s3cfb framebuffer isnt hardware accelerated using fbdev, preventing screen rotation and such. Any hint?

Hi,
I'm a french poweruser of Ubuntu (Server/Desktop).
May I have your script please?
Thanks,
RolluS

hi, i was almost at goal, but when starting X-session, it unmounts my sd card... any ideas?

Right when it starts?
Maybe some x app is taking over the sdcard.. just an idea

Debian GNU-droid

I've been working on a set of scripts that will install Debian on a running XDAndroid. There are a lot of sites that offer similar pre-packaged collection, but they always seem to include too much (aka 700M downloads) or have files from various places.
I have so far gotten the initial setup up and running pretty consistently. This is not meant to replace Rhodbuntu, but act as a co-existing subsystem along with Android using what is known as chroot. As Android uses the kernel derived from Linux, Debian's GNU subsystem can interface pretty well with our kernel.
One of the major stumbling blocks for the msm72k chips is that it is based on the older ARM1136 (ARM6) cpu, and the current armel distribution targets Cortex (ARM7) platform, which is incompatible and will segfault when run on our msm's. To my knowledge, Debian 5.0 (lenny) or Ubuntu 9.04 is the last supported binary-compatible distribution widely available. Debian is semi-supported with patches for the near future, but the same cannot be said for Ubuntu. While it is possible to cross-compile a newer version to run on ARM6, that is beyond the scope and man-effort for this project.
Currently, the files required to get a bare-bones Debian system is what I wrote in the past 24hr, plus either a debian root tarball (which runs about 90M on mine) or a Debian cdebootstrap-static that can be downloaded from your nearest Debian mirror. Using cdebootstrap means a consistent root image can be made from official Debian sources, as well probable support for Ubuntu or other Debian-based distribution having an armel static cdebootstrap (cdeb). In fact, since I have no desire to upload 90M over my phone, using cdeb is your only way to get your system using my script for now. Please read top part of debian.sh inside the zip file to understand how to use the cdeb support.
Using it is pretty straightforward. Unzip the contents to /sdcard, open terminal, su and cd, and sh debian.sh (along with what's necessary for cdeb). Once you have run debian.sh and have a working GNU subsystem, typing "linux shell" is enough to start a chroot'ed bash shell. I suggest starting off with "apt-get update" and start installing some other packages.
The script should be generic enough to work on any Android system that does not have a brain-dead busybox residing in /sbin (aka Epic). The only "odd" requirement is that lenny cdeb requires quite a few files in "/usr". I solved that by symlinking it to the toolset mount directory. You will also need at least 600M free on your SD card to create a looped fs image. Don't ask about VNC support yet, I need to go through installing it before that is supported.
As for other FS support that is up to the xdandroid kernel developers. They would need to add support for fs other than ext2 before I can even add support for that. Feel free to suggest ideas to improve this.
http://db.tt/pFkD9ou
Update for 0.20:
Rewrote the linux scripts.
No longer allow linux to start without su, due to restrictions by superuser.apk.
Added check command, will e2fsck the image if e2fsck is available.
Uses mount -t auto instead of -t ext2.
Update for 0.15:
Fixed typo for cp tool/data that caused copying of directory instead of content.
After running cdebootstrap continue with the rest of script instead of exiting.
Use mountpoint instead of relying on -e hack.
Add restart to list of commands.
Make sure stuff is unmounted after running script and make "stop" a bit more intelligent.
Change cdebootstrap default to squeeze.
Create /usr/conf/fs* if it doesn't exist, should get rid of error messages.
-- Starfox

Not sure where you got your info about 6.0 segfaulting - Squeeze is going pretty strong on my rhod 400.
Two-step debootstrap ftw.

Well, I've had supposed ARM6 binaries segfault or illegal instruction on me. If squeeze works, great. Perhaps you'd be willing to upload a root tarball for those who don't want to go through with doing debootstrap.
I was told by more than one person that lenny was the latest that properly supported ARM6 armel. My script is easy enough to modify to support different Debian distros.
-- Starfox

I just wanted to give you a heads-up in case you hadn't tried squeeze - it works just fine. I haven't put it through its paces yet, but I did get a vncserver up and going last night just to satisfy my curiosity. Other than some resolution issues, this too was fairly painless.
I think it'll take me more effort to upload a tarball on my connection than for a non-noob user to debootstrap 6.0 on their phone. As far as the beginner, I am not sure that a tarball would be doing them any favors, there's something to be said about head-butting against the installation process.
Good job with the script by the way.

Nice script. Worked on second try, some corrupt packages, not the scripts fault. Its a bit slow with connectbot but using a local dropbear helps alot.
Thanks

Updated to 0.15. Script shouldn't encounter mount-point issues and should create /usr/conf automagically. Updated the default to squeeze, I still used lenny-backport cdeboot-static to test it out.
-- Starfox

Updated to 0.20. Mostly internal changes, but now supports other filesystem types. Also added linux check to allow e2fsck to make sure nothing is corrupted.
-- Starfox

can someone help me, i get an error that cant execute /bin/bash no such file or directory, i installed busybox, what can i do?

[REQ] Tutorial on how to cook a custom firmware

Hi,
i 'm an archos user since not so long Thanks to the community I managed to install sde and root my device.
I have been lately searching for a tutorial or guide on how to cook a custom firmware, but I couldn't find such info.
Can someone write one for us newbies of Android and archos?
What I'm looking for is how to create the archos. ext4. update file from. aos and how to install busybox root etc..
thanks

Hi There,
Like most things on XDA, we've already covered it and the search is very much you're friend , However heres some links which sould help you on your way [HOWTO] Unpack and repack stock firmware, works also for gen8 and [HOW TO] Root, Install Busybox and SuperCharge your G9 These guides are on pages 4-5 of this section you might to work on that "searching" technique

Hi trevd and thanks for your reply.
I did find these links before i posted my request.
The first one provides tools for Gen8 and supposedly compatible with Gen9. But as i read through the thread, it seems to be dealing with a squashfs partition and not ext4 like the one we're using. So it confused me.
The second one shows how to install busybox. But how is it possible to do the same thing directly on the mounted ext4 partition?
Thanks

Thank you Quallenauge for your help.
i've tried the script, but it's not working properly at step 4. It seems that it's unable to mount the file to the loop. I'm using ubuntu x64. any idea?
Code:
mount: wrong fs type, bad option, bad superblock on /dev/loop1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Thanks

Then ./unpackAOS Do step 1 to 5 options, check archos_update_folder to see if firmware unpacked. Make your mods now, do the rest of steps.
1) clean
2) downloadPackages
3) setupBuildDir
4) createExt4Image
5) unpackAOS
6) copyAOSData
7) addSuperuser addBusyBox
8) finish

Thanks for the reply stevemp.
i'm doing the exact same steps but it fails at 4 while trying to mount the ext4 image.
I tried the same steps in OpenSuse and it seems to be working. I'm not sure if everything is getting extracted, but i'll check that.
Since the created update file is 512MB, is there a way to trim the unused space prior to flashing?
Thanks.

Fix CompleteLinuxInstaller

Well I ran into a little struggle when trying to use the complete Linux installer by default so I thought I would post how I got it to work correctly.
When trying to run by default I got errors stating it could not mount the loop device, it is a very simple
Download the bootscript4-3.sh file from
sourceforge.net/projects/linuxonandroid/files/bootscript4-3.sh/downloadSorry not allowed to hyperlink)
and rename it as bootscript.sh
After you have that file ready move it to the directory /data/data/com.zpwebsites.linuxonandroid/files/ and replace the file that is already in there.
You now have a working CompleteLinuxInstaller app enjoy!

Hi. Thanks for your efforts. Just a couple questions. Do you need to use a kernel that has SELinux set to permissive. Also, can I just take the ubuntu image file I was using on my GN II and bring it over to my GN 3 to use.

I am using a kernel with SElinux set to permissive, also any arm based Linux distro should theoretically work, I do no believe they are phone specific. I would recommend the sabrekernel.

Ok. Great! So basically once I have appropriate kernel, I then run Linux on Android. It will set up its file structure and I then I replace bootscript.sh and I'm good to go.
EDIT. This bootscript file is from Linux on android project. I wonder if it is going under further testing. Doesn't hurt to try, and, of course, report to them as it is an open project!

Arch Linux for Shield TV

I present to you instructions on how to get Arch Linux working natively on your shield TV dual booted with your Android rom. This is all thanks to the amazing people in this thread for getting Ubuntu on the shield and would not be possible without them.
http://forum.xda-developers.com/shield-tv/general/ubuntu-utopic-nvidia-shield-tv-t3150352
This install will put arch Linux on a micro SD card, and does not modify your shield at all if you so choose. First download these 2 files.
Archlinux Stage 3 install
http://archlinuxarm.org/os/ArchLinuxARM-aarch64-generic-latest.tar.gz
Kernel (Credits to jagger11 from his thread) You only need nvidia_boot.img
https://drive.google.com/folderview...ZSS1VxUVBJZmFqSXNFYUhpN2lHcklhVzZtX0Z5OENxdU0
To intstall
1. Unlock your shield TV
2. Format your SD card to EXT4
3. Mount the SD card
4. As the root user on your linux distro (not sudo) run this command (From the same directory that you downloaded that file to, and replacing mountpoint to where you mounted the SD to)
bsdtar -xpf ArchLinuxARM-aarch64-generic-latest.tar.gz -C mountpoint
5. Unmount the drive, then run the command "sync". When that finishes, pull the SD card from the computer.
6. Put the SD in the shield
7. Reboot to bootloader (adb reboot fastboot) with your preferred method
8. Boot Linux
To boot it once run this
a) fastboot boot nvidia_boot.img
To save to recovery run this (Reboot android to recovery to boot arch after)
b) fastboot flash recovery nvidia_boot.img
Default users and passwords are
root:root

My request to you. I am not a kernel dev any more. I once was, but things have unfortunately changed, and I don't have the time or resources to learn it all again. If anyone wants to develop a kernel for this, please do and I'll add it in the OP. Unless something changes, and Ubuntu kernel from the Utopic thread will work fine here)
I'll format this a bit better later, but hopefully this is a good start. I have some good tips and tricks to add if people are interested in this, and was able to watch quite a lot of my videos in vlc even on framebuffer.

Those packages will do you other than desktop manager, but I have to say, I'm pretty minimalist, and arch is by default, so don' feel too bad. I've just been using arch for the last few years, and was using Gentoo before that, which is all even more manual and source built.
https://wiki.archlinux.org/index.php/Xorg
That page will go through it all. Once you know what desktop manager you want (I recommend XFCE if you don't know what, or LXDE which is even lighter), check the pages out on there for them. It covers haw to do absolutely everything. I honestly use arch linux for the wiki. It's by far the best source of linux information on the net I'd be willing to bet.

Yeah, it's actually got nothing to do with architecture. Not quite sure why they are named as such. Also, xf86-video-fbdev isn't listed there as it's a last resort kinda thing, but it works well on the shield for the moment. Once I figure out why my system stops booting linux from time to time, I'll work on GPU drivers. Hard to know what broke it if I don't fix that first.

I guess one issue is the device tree which will not be provided by uboot like on normal arm systems. In the kernel configuration you can define that the device tree is appended to the kernel image (e.g. by "cat Image foster.dtb > newImage"). Maybe this is a solution.

Thanks for the info. I'm going to have the next 2 days off work, so I'll definately get to work. I'm going to need assistance in getting a working kernel as I don't have an x86 machine around currently. Crazy, I know, but I don't. I'll see if I can get the drivers installed if someone works on a kernel. If not, I'll contact some of my linux friends and see what they come up with.

That link mentioned:
"The first prerequisite is that you must use an up-to-date U-Boot as bootloader"
Jetson TK1 and TX1 uses U-boot, Shield TV however uses fastboot not U-boot and the kernel is not Linux but Android.
I'd really like someone can have u-boot ported to Shield TV as 2nd or 3rd stage boot loader.

Damn! I just found out that this CONFIG_ARM_APPENDED_DTB trick only works with zImage but not with Image as needed for abootimg. Currently I don't have an idea how to get a mainline kernel running on the shield tv. I guess uboot makes no sense since we don't have an uart.

u-boot could use netconsole:

My kernel can boot to command line archLinux now, I updated the procedure:

I'll try that kernel when get home with the gui running on framebuffer. Should work.

Any chance you can maybe try to patch in the Nouveau kernel driver from here?
With a kernel running that I can get 3D acceleration work started. Till I get that sorted out I can only guess if my changes are working or not.
I'll also be trying to get the closed source binaries running on this. I have decided to pay a decent sum of money for a VPS to get a compile machine. Hopefully we can get this project rolling.

I did not expect it'd take me so long just to have gui running for archLinux. As I mentioned before this thread started, I'd like to try Cuda 7.0 on ArchLinux. I main goal is to have Cuda working so I can use Gpgpu of Tegra for image processing and other applications.
A script or procedure for post installation to quickly install gui is what I was interested. To install archlinux rootfs without gui was very simple and I did it the first day when I received my Shield TV to troubleshoot Utopic rootfs. I could read the wiki to have gui working for archLinux, but I have to spend my time on other things, e.g., without hope to have u-boot or multirom working for Shield TV, I have to learn Android kernel (I'm in the process of clone Android kernel source tree).

I'll write a script for you once I get home. Thanks for the input. Any requests for a desktop environment or window manager? If not I'll just pick a light one like lxde.

Any desktop is fine. I'd like to push Cuda 7.0 from my build PC to archLinux like I did for L4T. Network connection and any desktop are what I need. If it works, we can see performance differences between 32 bits and 64 bits
Thanks.
