Hi experts.. sorry for the totally noob questions..
1) is it possible after i extract any "boot.img" from any kernels built, i can edit those .rc files and then rebuild it?
2) to edit one's cpu properties (freq, voltages n so on) can i just edit .rc files or i need to build from source? If source, which folder/files i need to start?
Thanks.. :[email protected]#$%&*

Yep, this is most certainly the right section, namely development. Questions definitely don't belong into the QUESTIONS AND ANSWERS section. But go on.
To make my /system, /data and /cache formatted ext4, just edit "init.tegra.rc", "init.rc" or both? Notice at init.rc, there are line mention yaffs2, then at init.tegra.rc, ext3? Which 1 should i edit?
Sorry guys.. just that i'm a slow learner.. (

Hello,
I haven't tried modifying ROMs. But my suggestion would be to get an ext4 ROM and study how its scripts work
Ive tried view all the sources, but i can detect which file/folders i need to edit.. as example, i know to create my own freq, i need to look a file at /driver/freq/freq.c... but which line i need to focus?

I honestly have no idea. But there are a lot of devs here who have experience with kernel source. Try maintainers from cm7, paul (modaco), spica, or topogigi.
Hopefully they read this thread @ my pm.. like to learn..

Hey guys,
let's try to get Ubuntu working on our tablets.
adbd is included in the images, so you have a root shell over adb
SDE required.
Extract all.
adb push ubu1204.img.ext4 /data/media/
Reboot - SDE - Flash kernel and initrd
Multiboot menu 0.3 - ubu1204.img.ext4 (from the menu to start the ICS, such as "archos.ext4")
Done.
(passwords: ubuntu - ubuntu root - root)
Working:
- Booting on 80G9 and 101G9
- Touchscreen (touchpad mode)
- Keyboard via OTG cable

Sorry, I don't understand your question :S
how would i implement a dualboot
You can take the initramfs.cpio.gz posted by letama in another thread (look at the link to Ice Cream Sandwich - the file is inside the archive you download).
Then extract it and have look at the scripts, which are provided there.
Basically you have to get the system to ask you, from which filesystem image you want to boot
yep! you need to install SDE, restart your device, go in the developer menu and flash the initramfs.cpio.gz that letama posted in the ICS post, atleast that's how it was in the Gen8... by the looks of it the SDE menu is the same. Hope I helped
i wait the multi OS install

Nice, I'll give this a go now.
Edit:
Works on the 101G9.
Keyboard Functions through OTG/Host Cable.
USB Mass Storage (Pen Drive) Functions on 3G Stick Port
Not tried anything else yet.
Are you using a lot of the same kernel objects which android is using?
Excellent Work.
alright thanks

Thank you very much, and also thanks for testing
I am using initramfs + kernel + modules provided by letama for his ICS-build.
By the way - I will upload a new build this night.
I have managed to get basic network functionality via adb + usbcable, so I have upgraded all packages and installed a touchscreen keyboard.
In the new build the LCD backlight brightness is now set to max on boot.
I also have added a user with sudo-permissions, so now settings are saved on reboot (not like in 0.1 where guest sessions were created).
Oh, and I will change the filesystem type from ext3 to ext4.
Still no real progress on WiFi or sound
P.S.: New build will support choosing between booting ICS and Ubuntu
//edit: sry guys, got some problems with my internet provider. i get reconnects every 30 seconds. i hope they get it fixed till tomorrow... sorry for delay, i'm going to upload the stuff tomorrow..

Might be worth giving it a go with a version 3 kernel, you may get some free driver support. although I could be talking nonsense

I activated the root login with my own password from adb and the touchscreen keyboard worked straight away on the 101. It must come with the the drivers preinstalled. I think letma's' done some work into the difference between the 80 and 101.

I've been playing with this all night. I think the drivers have been integrated in the main linux kernel so you should be able to build your own.
They could some prebuilt binaries out there as the OMAP4 board seems quite a popular board.
Also you might have some joy with this http://dev.omapzoom.org/pub/scm/integration/
It's all Good!

Hi Guys,
A1Pha, sorry, didn't have time to test your build, too much stuff going on...
Here is a quick feedback on wifi that may help you:
In android, here is how it works (from memory, don't have my laptop to check)
1) you need to create a nvs file corresponding to tablet, check android init.rc for the way it's done there...
2) Then when you do need wifi, insmod the tiwlan.ko
3) Then, load firmware (check wlan_loader in android init.rc, you should be able to reuse the command) and nvs. If all goes well up to here, you should be able to do ifconfig tiwlan0 and it should have a mac address.
4) Then start wpa_supplicant. You need the appropriate version of wpa_supplicant, 0.8 I think in android source code. You may want to build source code from android source with the appropriate options to remove android extensions.
Again, this is from memory, I'll try to give you more details tomorrow.
Regarding audio, this is mostly alsa so it shouldn't be impossible, you should be able to re-use the configuration found in archos rootfs in /usr/ sub directories. You have to insmod the proper modules though.
Best,
LeTama
Suggestion for the sound, try running the alsamixer and playing with that... worked in debian...

ahh. Thanks for that letama , You're a fountain of knowledge.
I'll give it a try during the holidays.
I was playing about with wpa_supplicant and android kernel drivers. I didn't have the right magic ) and my kernel knowledge is still in it's early stages (only been on the linux desktop for 1 year).
Has anyone got the fbcon framebuffer console to work on the Atrix ?
I have sucessfully compiled an atrix tegra kernel from source and booted on my 4.5.91 (2.3.4) Atrix.
I have 'sucessfully' set the frame buffer console and enabled fbcon via menu config.
These were compiled as builtin modules and built a zImage without any issues.
However, the new kernel fails to boot where the 'default .config' built kernel will boot.
I was hoping to get lucky and override the /dev/graphics/fb0 limitation on these devices. I need the framebuffer to run a framebuffer applictaion proir to starting up android after the kernel boots. I have the capability working on the nexus one just having trouble porting to the Atrix.
Does anyone know a simple kernel trick to fix the framebuffer?
Thanks in advance.
Maybe this will be of help

It sure was. Thank you very much for the shove in the right direction.
I grabbed that git tree and configured tegra_olympus_cm7_def_config and set that switch. So I can read the framebuffer but have yet to be able to display what I right. Thanks again.

Hey all. So I was looking at this cpu frequency governor for the razr:
http://forum.xda-developers.com/showthread.php?t=1367255
I was wondering how I could get this working on our devices, so, just for curiosity's sake, I copied it to the phone and ran insmod on it. It did a quick cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors and found the new governor listed, so I opened up SetCPU and set it as the governor. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor told me, however, that I was still on mot_hotplug, so I switched to ondemand and then back to the eprj governor... still told me I'm on ondemand.
I figure that the razr's and droid 3's kernel modules are not binary-compatible, so I'm gonna need to recompile the module. How do I go about doing this?
Thanks.

loop devices are already supported. If your using linux installer from the market just ignore the warinngs. To manully mount a loop device.
Code:
# mount loop.img directory
If for some reason that doesn't work use losetup.
Code:
# losetup /dev/block/loop7 loop.img
# mount -t auto /dev/block/loop7 directory

Hi to all, this time I'm trying to port Ubuntu Touch, I have built device-specific zip file for Ubuntu Touch but after installing it and daily preinstalled Ubuntu armhf image from http://cdimage.ubuntu.com/ doesn't boot, no black screen, only Galaxy bootscreen, in kernel's defconfig I've done all modifications listed on https://wiki.ubuntu.com/Touch/Porting and compiled with brunch janice

ADB not working in bootscreen, last_kmsg is useless because to enable ADB I have to enter in recovery so the file is overwritten. With device-specific package the recovery's graphic changes according to Ubuntu, and flashing a CM kernel boots the Android part (I can see CM bootanimation, but OS obviously doesn't load). Maybe the problem is in the kernel's ramdisk, I have to add something to init.rc or change BOOTCLASSPATH to boot Ubuntu?
Any updates?

I don't think the project will be succesful.As you know we even can't get a proper AOSP ROM and Cyanogens are unofficial and we should hope another OS ?
But of course I'm not hate just saying; maybe my knowledge would be false, thanks for work.

This project is just for test, the OS is based on CM kernel, so it should be boot if all is done correctly, I think that the error is in the kernel's ramdisk

Are there any realistic chances that there will ever be a Ubuntu Touch OS for this phone? I mean i certainly do not ask for a ETA. But i would love to have a Ubuntu Touch on my phone. If this is not possible then Ohhhkehhh no problem. So will there any further progress on this or not?
Finally something moves! I recompiled again with other changes, now after installing device-specific zip file and preinstalled image I get a bootloop with a black screen for 5 seconds, so kernel tries to boot OS but unfortunately I can't use ADB shell because is not working...
If any dev can/wants to help me is welcome! Two brains are better than one...
Uart. You need uart to debug it if the kernel cannot reach the point of loading adb!

Or is this here just a relict of a dead end road?
