[ROM][P6800][OnHold]Ubuntu-touch dev preview(18.03.2013)

dun1982 · Mar 2, 2013

I have put this project on hold for now. I flashed latest Austrian ICS build to my device and continue using it as my Kindle reader on my travels. IF somone manages to fix the two issues with kernel, send me a message and I'll continue working with the repository. But for now I'm not thinking nor touching the subject before Easter. Thank you for participating for now

I've started porting Ubuntu-touch dev-preview to the Galaxy Tab 7.7 (3g). If you do not understand it already, you flash this at your own risk. There is now also a Ubuntu-touch specific device page here: https://wiki.ubuntu.com/Touch/Devices/p6800. I'll try to keep this thread and the Ubuntu devices page as close to each other as possible.

Big thanks to Daniel_hk for helping with boot.img

Now It can be booted, but the screen is still black

Also, without working wifi and display, the preview is basically unusable... Next steps should be these:
1. Get wifi drivers working.
2. Get display drivers working.

Code:

root@localhost:/# uname -a
Linux localhost 3.0.15-CM-g1dc3074 #2 SMP PREEMPT Wed Mar 13 00:43:37 EET 2013 armv7l armv7l armv7l GNU/Linux

What works

Ubuntu-touch dev-preview is flashable.
It boots!

Known Issues

Kernel is based to the CyanogenMod/android_kernel_samsung_smdk4210, but it is a mess. So forked it, took code here and there (mostly from locerra's JB build).
Kernel is based 3.0.15 and no newer one available (yet).
Most of the drivers in kernel had to be turned off, because build was not succeeding...
bluetooth: Doesn't work
audio: Dock audio doesn't work.
hwcomposer: HDMI dongle doesn't work.
wifi: Doesn't work.
camera: Doesn't work.
.. and lot of kernel level bugs for sure.
Displaydrivers are not working (yet).

Release notes

Version 0.2 (13.03.2013) - Now it boots, see release notes
Version 0.1 (07.03.2013) - Intial release, nothing works

Not 6810 versión?

I cannot test it for anything else. The kernel sources are from CM10.1 that was in use from locerra, so in theory it should work with i815 and with p6810 as well. But I cannot give you any guarantees...

And also before I get this build to even start with my device, I do not think that sharing image would help anyone. But if you are a developer, I would like to talk with you on issues that I might have missed or done wrong. So contact me

Not much. The generated image is missing /data/ubuntu completely and that is the reason why the image does not boot. I got also flu and fewer, so I have had not that much time after the weekend to look on the issues on that.

I'm also waiting if I get any answers from Ubuntu touch emailing list regarding the problem and where to look for answers, but my quess is that it has something to do with the devices fstab file...

dun1982 · Mar 6, 2013

Good news everyone!

Just got a very good answer the problem I had with the /data/ubuntu-folder missing from the image. There was no image provided for the actual Ubuntu at all by the build-process...

When I get home from work, I'll try to find time to look into the build process if I can include the actual Ubuntu image to the ready made image and then release it after I get my device to boot. But it seems that I got the right nudge forward for this now :highfive:

dun1982 · Mar 6, 2013

Hmpf, still not booting. Now the /data/ubuntu logs are unmodified, which would point towards kernel or fstab-issue (ie. /data/ubuntu is never used...).

Doh... still not working... Any ideas anyone?

dun1982 · Mar 13, 2013

Ok, new version build from different repositories (thx, danile_hk for tip).

I'll test the new image this evening when I get back to home, and I have my fingers crossed that I can get the device to boot up and even display something useful. After that I can start looking for ubuntu developemnt

dun1982 · Mar 13, 2013

New version did not work, but then Daniel_hk gave me working boot.img. So now I need to find out what the heck is wrong with my repository and fix it so that I can get working boot.img from start and also the device configuration has issues. Both repositories are currently out of sync I'm afraid

It seems that I hit the wall (again) with the mentioned big issues.

For now, I keep some sabbatical from Ubuntu Touch things (ie. I flashed ICS Austria to my device) and use it as my Kindle reader again.

If by miracle I get more info regarding how to get the Kernel working with Ubuntu Touch, then by allmeans I continue working with this project. So far it just seems that making a working image, is out of my hands currently.

UpInTheAir · Mar 18, 2013

At least you had a go. Thanks for your efforts, and hope you might have another crack at it later on.

I'm feeling a little bit that way right now too, and put my ICS kernel on the back burner. I think I'm trying to multitask a little too much at times....

Yep, a break is what you need, maybe some clarity will come after you've had a chance to recharge.

Any update on this development?

Not much, I have had no interest to spend time with this topic because I have been very busy IRL. After I get my new house renovated fully and get my job tasks done, I wont be spending much time with this project. Feel free to use any sources provided in this thread to further advance the subject.

But this wont go forward that much, if the GT-P6800 wont get official CM10.1 update...
