This is the result I get directly after flashing the kernel Jhinta posted. Would you like me to upload a video showing the kernel being flashed and then uname being run?
Jhinta Kernel for Lilstevie Ubuntu
- Thread starter Jhinta
- Start date
doesn't change the fact that the running kernel is my kernel, that I am 100% sure of with that uname -a pic
Yes! It's sbkv2 but not a loop mount, I just dd the rootfs using the method shaola posted. So this can't be done on my TF, sorry for the trouble.

Hi,
great work Jhinta, installed your Kernel and works like a charm.
Found a few things that are still missing.
I had a few Problems with the touchpad, but was able to fix it with the ubuntu 12.04 mtrack driver. Had to add an InputClass to the xorg.conf though
I replaced the fb.c with the one from the latest Nvidia Kernel. As far as I can tell GLES ist working. Nice thing is ubuntu 12.04 has an nvidia-tegra package.
Wifi works with Networkmanager.
Sound is not working for me with the new Kernel. I'm not sure wether it's the new Kernel Driver or the Ubuntu update. Sound with aplay is still working using lilstevie's Kernel. But pulseaudio makes some pthread_mutex_unlock(...) assertion. So I guess it's both the Ubuntu update and kernel driver.

I just tried installing the kernel and have run into some issues. I installed l4t r12beta harmony drivers, copied over the modules, and flashed the 3d kernel. When ubuntu begins to load all I see on the screen is tux. The screen then briefly (>1sec) turns off and then turns back on, completely black. I have no command prompt and no ui.
I have a feeling this is due to installing the wrong l4t drivers but am not sure. Any ideas?

Hi,
The X-Server is not starting. I can think of 2 things you can check.
there should be a section in the file /etc/X11/xorg.conf
the other thing is a bit more complicated. Flash the old Kernel, install openssh-server, try to connect to your pad with ssh, flash the new kernel an try to connect after the screen flickered.
You will propably find what's wrong in /var/log/Xorg.0.log. My guess is the Nvidia script detected the wrong X abi and installed to wrong version. If thats the case you can try to install an the remote console again or you have to copy the correct tegra_drv.so manually.

Thanks, it was a l4t driver issue. I put the original kernel back on, reinstalled the l4t drivers again, and then flashed the 3d kernel. It now works.
The nVidia script does not detect X abi version, you need to manually specify it if it is not version 10
your working on nvidia mainline right?
Also about ABI one can specify ignore AEB version in xorg.conf dont realy know if it works, and there is no 12 version -> nvida still has to make it.
I will be, I am busy with another project at the moment. anyway, abi version 11 is what is used in precise and oneiric uses 10
How do I manually specify my abi version? I just did a clean reinstall of ubuntu, upgraded to 12.04, and now I cant install the nvidia package.
Update on Ubuntu for TFP
Hello forum,
How is it going with ubuntu for transformer prime atm?
Anyone can give an update status?
Been trying for weeks to run it properly, but i haven't got the needed expertise.
Thanks for any help

My misc participation in this thread was in hopes of getting a nice Ubuntu setup on my Transformer. I, unfortunately, also have an sbkv2 version. So, if the kernal blob currently being tested (Ubuntu-3D.zip) is too large for the partition, is that ever fixable? Maybe I misunderstand the problem, but could we modularize a few more things, so it can fit in the standard partition and allow it to work on the sbkv2 devices? Let me know if I am barking up the wrong tree or if I should setup a build enviroment and see what I can do. I have not compiled an android kernel yet, so I will have a little learning curve. I have compiled standard linux kernels for a few archs, and have done some cross compiling before, so I am sure it is within my grasp.
You can make it smaller more modules , beter compression . Just try and find out

Give me the config of the system /proc/config.gz
I dont have the system but if your willing to try ill send you a kernel.
As always use at own risk
I tried to change the xorg.conf to ignore the abi version but it didnt seem to have an effect.

I am in the process of writing an installer, at the moment the install method is not the best and trying to improve it to be a little better

9Dont have this tap anymore so cant support it anymore !!!
I do things manual as i want to know what has be done !
So every thing below is hardcore installation. This will give you the why and know how of things !!!
About bootimg.cfg
This file is need for creating boot.img
You can find it by unpacking a boot.img,but one is provided already.
The important part of this file is the first and last option.
The first one will say how big the image wil be, and the last is kernel cmdline.
This is also wehre you say loop= for a loop file
Pack or unpack blob files
Code:cd /tmp git clone git://github.com/AndroidRoot/BlobTools.git cd BlobTools make -j2 sudo cp blobpack /usr/bin/ sudo cp blobunpack /usr/bin/ cd ~
Unpack a boot.img
We create a folder and place a boot.img in it.
Code:mkdir ~/test cd ~/test abootimg -x boot.img
Unpacking a initrd image
Now you will have a directory with the ramdisk source files in ~/test/ramdiskCode:cd ~/test mkdir ramdisk cd ramdisk gzip -dc ../initrd.img | cpio -i
to repack it, run
for gzipCode:cd ~/test/ramdisk find . | cpio -o -H newc | gzip > ../new-initrd.img
for lzmaCode:find . | cpio -H newc -o | lzma -c > ../initram.lzm
This will give you a new-initrd.img file in ~/test/ for you to use............versions<
Go to the folder and select ALL file or folder BUT source and build !!!!
And compres it file wel be made in home.
modules are install in ubuntu in /lib/modules/
About kernel and initrd and boot.img and blob
Kernel = basic hardware installations and setup
initrd = like a ramdisk
boot.img = kernel + initrd
blob = boot.img + TF special header
Blob file you find in cwm.zip like a kernel update for android
boot.img you will find when using nvflash
kernel gets compiled from a git or source
initrd you can make your own or reuse
i will create cwm.zip to do the flashing
To do this i do.
This will give me a ubuntu.img ready for nvflash but i want cwm.Code:mkdir ~/test cd ~/test cp ~/TF101-GNU-kernel/arch/arm/boot/zImage ~/test/zImage abootimg --create ./ubuntu.img -f ./bootimg.cfg -k ./zImage -r ./initrd.img
so i do
(LNX is boot partition dont change this unless you know what your doing)Code:./blobpack kernelblob LNX ubuntu.img
Now i got a new file kernelblob that i can add to a cmw.zip file
To do this , open !!!! the cmw.zip below and remove and add the file kernelblob.
Thats it, and ready for flashing.
Rootfs
You sould be able to use any rootfs that is for arm.
you can also build a rootfs with rootstock
keep in mind a rootfs kan have diffrent types of names like ( rootfs.img.ext234 or ubuntu,dabian,linux.img.ext234 or evrey name you want it to be its just a name+ext)
If you want to relock it for oem-config ( nice first setup like name location keyboard setup) do
Code:touch /var/lib/oem-config/run
Ubuntu
Kbuntu
XBMX
So how do we even flash ?
I use nvflash directly or cwm
The easy why is just using Olife.
Keep in mind that i will never use uboot , only original bootloader of android.
So dualboot is what you need.
if you have dualboot flashed, do this.
Replaced (backup!) initrd-2.6.38.img and 2638-zImage in the kernel folder with my files,
and in Olife update your chromium kernel.
For those that want to use a loop file
Just flash this zip file
And copy the rootfs to sdcard (nand) /sdcard/linux/ubuntu.img (more will come, thats why linux/ubuntu.img)
Wifi setup
Wifi simply needs 2 files and you can get them from android space -> then copy them to Ubuntu space to /lib/firmware/
/data/misc/wifi/nvram.txt -> /lib/firmware
/data/misc/wifi/wpa_supplicant.conf -> /etc/wpa_supplicant.conf #optional
just use a root exploror to copy them to sdcard or usb ( this can alo be done when your in Ubuntu space (/system = mmcblk0p1, /data = mmcblk0p7))
and put them on the right place for Ubuntu.
Bluetooth setup
There are 3 file needed from android space, to get this,
Enable bluetooth
Rename you bluetooth name to what ever you want ( once in Ubuntu you cant change this !!!! )
Leave it on !! and boot to Ubuntu
/data/misc/bluetooth/{bcm4329.hcd,mac.txt} -> /lib/firmware
brcm_patchram_plus (lives on the net) -> /usr/sbin/brcm_patchram_plus (already in)
As last edit /etc/init.d/bsp-tf101 and correct your mac adress --bd_addr ***** (replac *** with mac !!!, mac is located in mac.txt)
.
and reboot and your done.Code:#! /bin/sh do_stop(){ #look if Board Support Package is already running PS=$(ps -A | grep " brcm_patchram_plus\>") if [ -n "$PS" ]; then echo "* Stoping Bluetooth Support Package..." killall brcm_patchram_plus fi } do_start(){ #if already started then stop first do_stop #now start all board support binaries echo "* Starting Bluetooth Support Deamon..." rfkill unblock 0 modprobe bcm4329 /usr/sbin/brcm_patchram_plus --enable_hci --baudrate 921600 --bd_addr ***** --patchram /lib/firmware/bcm4329.hcd /dev/ttyHS2& # making sure the nvtegra dev nodes have the correct permissions echo "* Setting correct permissions on nvtegra device nodes..." chmod 0666 /dev/nv* /dev/tegra_* } case $1 in start | restart) do_start ;; stop) do_stop ;; esac
Installing Tegra HEADER files ( needed when building things like XBMC )
Copy as root all folder to /usr/include/
Installing Opengl-ES
Download the Tegra drivers from Nvidia
Once downloaded unpack it and open a cmdline and go to that direction Where those files are and type,
-r = your root directeroy whey you want to install thisCode:sudo ./app*.sh --help
--abi = witch version of abi your running, to get you version run in ubuntu on TF
So when running this directy on the TF in Ubuntu you wil get thisCode:aptitude show xserver-xorg-core | grep abi
Code:sudo ./app*.sh --abi 10 -r /
Get audio working
Then open alsamixer and enableCode:sudo usermod -a -G audio sudo chmod -R 777 /dev/snd/*
playback
Left And Right speaker mixer DACL/R
Set DC input to DMIC
And sound sould work right away.
Install zram
Code:sudo wget -O /etc/init/zramswap.conf 'https://wiki.ubuntu.com/ARM/TEGRA/AC100?action=AttachFile&do=get&target=zramswap.conf'
Installing XBMC
sudo apt-get install (try installing all dependencies you can in the readme.ubuntu in xbmc folder , some will fail so just remove them) )
Code:cd ~ git clone git clone git://github.com/xbmc/xbmc.git cd xbmc ./bootstrap ./configure --enable-tegra --enable-gles --disable-openmax --disable-vdpau --disable-hal --disable-joystick --disable-debug --disable-dvdcss make -j2 sudo make install sudo apt-get install libgl1-mesa-swrast
Loop or native parition
in your config (dualboot.cfg)
You kernel cmdline would be
( if you have native root=/dev/mmblk0p8 rw.........)
( for loop support you add loop= ( location of file !!! + root= (the partition where the file is located !!)
root=/dev/mmcblk0p7 rw loop=/xxx/xxx
Default Kernel
files
Support
hdmi ( audio ? )
USB ( full working )
jack ( mic ? )
Opengl-ES
zram ( needs script also a most have beacuse of low ram space )
-more to come
Sources
kernel
Khronos header package
Tegra Opengl-ES drivers
Blobtools
THANKS TO:4
If you look in the wiki, there's a link to a post by me which contains a pretty detailed guide on how to compile a kernel and flash it. When you reach the stage involving abootimg, you'll need to update the config file passed to it with the -f option, and change "root=mmcblk0p8" to "root=mmcblk1p1" (or whatever partition it's installed on - you can check this by mounting it under Android/Linux then using the 'mount' command to check which device it corresponds to)
BTW, you can have a dual boot while retaining CWM - you keep CWM in the recovery partition, and modify some zip files to flash the packaged kernels for Android and Linux. (This is also the easiest way to try new kernels.) More instructions on this are in the kernel compilation guide.
-------------------------------------------------------------------------
In case anyone was wondering where I was, my TF was subject to a warranty claim (took them a month just to reconnect the LVDS cable). I'm currently in the process of repartitioning it and installing Debian armhf. Once I've got the new kernel working, I'll post a newbie friendly guide.4Kernel update
If someone is still interesting, I've merged kernel with lastest l4t nvidia souces (r16r3-rc)
Changes:
- framebuffer now fully works, switching between X and fb works.
- usb hotplug bugs fixed
- wifi disconnects fixed (used bcmdhd from cyanogenmod sources)
- I've remapped upper keys for F1-F12 scrollock, pause, ins, del.
Sources at github.com mozggg TF101-GNU-kernel
(sorry, external links blocked)
gnu.zip - for CWM flash. Includes kernel and modules. Installs on mmcblk0p8
bcm4329.tar.gz - firmwares for current bcmdhd driver and .hcd for bluetooth. Must be extracted to /lib/firmware
