[LINUX][POSTMARKETOS] Native Linux on Samsung Galaxy Tab 2 (unified)

[Yxles]

Making GPU work on mainline linux requires a bunch of tweaks and changes, but we can confirm that gpu works! There will be a release coming soon once we get some time off

Post is coming soon

Eyyy, nice to see that this was still being worked on can't wait for the next update

Sorry to bother the thread. On the last chance to make a P3100 TAB 2 survive next 2023...can I install this awesome LINUX "rom" in order to make this ancient tablet a mini server for domotic?
I want to run HOME ASSISTANT (Linux based), prices of Raspberry Pi 4 are over the top and I don't want to throw away this P3100 (is starting to become sluggish for everyhting, even the most simple app).

Dont worry, you're not bothering at all and it wont hurt to try it. Just make sure that it supports arm32

Hello all!

We are proud to release the 5th dev build of this device!
Unfortunately, the images are a bit old (PostmarketOS 21.12, which is unsupported; and Alpine 3.15, still with support), but they still work as a proof of concept (and Plasma Mobile UI is available for testing).

I have uploaded two videos, showing Phosh and Plasma Mobile.

NEWS
---------------

Although this release still covers only 7-inch devices, the next one will also cover 10-inch devices.
This means that downstream releases will be deprecated, and all devices will be able to work with mainline images.


ADDITIONAL NOTES
---------------

When building newer images from scratch (from pre-alpha 3.17 edge release), Phosh still works with newer releases, but an additional package is needed.
There are issues for getting Plasma Mobile to work in newer releases.


VIDEOS
----------------

* Showcasing Plasma Mobile:

* Showcasing Phosh:

Made with Blender 2.93.10 video editor.

* Video Backup: https://sourceforge.net/projects/sgalaxy-tab2-linux-images/upload/postmarketOS/Videos/


DOWNLOAD
----------------

MAINLINE ONLY (10-inch devices won't work!)

Hello, I'm very looking forward for the next release for the espresso10s, since I have two of them laying around doing nothing....

Yesterday I tried flashing pmOS on one of my tablets with different Interfaces but none of them could be used since all attempts stuck at the "postmarketOS Loading...." screen. I used pmbootstrap to make a recovery zip and adb sideload with twrp, then heimdall for flashing the kernel (heimdall flash --KERNEL boot.img). It looked like if the kernel has loaded (ifconfig, dmesg and lsusb recognized a linux device hanging on USB with IP address), but ssh connection gets refused; since I dont have SD cards and external keyboards with matching interface I can't get it working otherwise.
I would be very glad if someone could give me some advice for how to get it working, or a configuration where it works with espresso10.
best wishes :3

https://gitlab.com/postmarketOS/pmaports/-/merge_requests/3627/ Once this gets merged, espresso10 will also be supported (on mainline)

 

[lucazade]

Hell yeah! Linux on my old Samsung Tab 2 7.0

 

[Mighty]

10 inch support merged on postmarketOS
Pvrports images will come soon

 

[nulldayo]

Yes, I got pmOS on my 10 inch device just right after the merge
I have another 4 of these tablets, I think I will get pmOS on all of them lol

I wish you all a merry christmas!

 

[lucazade]

I'm a bit confused about which images is better to install on this device.. I need your help

At the moment I've installed the following file via TWRP install:
pmos21.12-samsung-espresso3g-espressowifi-phosh-alpine3.15_kernel5.17.zip
and it is working quite fine.

I would like to know if building from scratch with pmbootstrap or
using community 22.12 prebuilt img files will include pvrports and optimizations.

Sorry if already asked but I wasn't able to find an answer.

Yes you can build using 22.12 and use the pvrports repo https://gitlab.com/pvrports/pvrports/-/tree/v22.12 to build, we will be uploading prebuilt images for pvrports soon!
Happy Holidays!

Hi,
Installing POSH 22.12 in the system partition is not possible right?
I tried to flash it through TWRP, but it was unable to detect ROOTFS when I tried to boot.

Then I flashed xfce, and it worked

Phosh is bigger than the system partition (its become an issue now) so you could install it to sdcard or userdata partition.

Hello @Mighty and @aat596 thank you very much for the effort and time spend to give a third life to this device.
postmarketOS on this eleven years old Tablet is an incredible and fantastic thing.

i cannot find how to deal with pre-build.IMG, Heimdall faill at 2%
and i don't know how make a TWRP compatible .ZIP from those .IMG
ls "dd" could be the solution ?

so i build myself for recovery using pmbootstrap,
i share the builds here :

postmarketOS for Galaxy Tab 2

Murena - Choose freedom

murena.io

but how to define swap partition (before, during or after building) ?

https://wiki.postmarketos.org/wiki/ZRAM Did you check this page out?
Also heimdall seems buggy with install pmOS for me as well

Hi,
I have green glitches on all kernels except 3.0.101, I tried to build the system myself, nothing has changed. Changing a DE doesn't change anything either. Moreover, glitches appears even when nothing other than boot.img is installed. Model is GT-P3100. What can I do with that? Sorry for my bad english.

 

[Mighty]

Ah youve used pvrports or pmaports? Also 3.0.101 is ancient and has very less support (no GPU, charging etc).
The green lines are a known bug but not to this extent, maybe try changing to dark theme.
Wdym by nothing other than boot.img installed, you need boot.img + rootfs for any linux image to work

 

[egor835]

Ah youve used pvrports or pmaports?

Both, and both have these glitches.

try changing to dark theme

Did not help. In fact, this is the second tablet with a similar problem, both GT-P3100 and both were bought in Russia, maybe this is some kind of regional feature?

Wdym by nothing other than boot.img installed

I formatted all partitions and installed only boot.img via TWRP and the "boot partition not found" screen also has these glitches (see pic 3)

Btw, thanks for help

Nope, mostly an issue with the GPU drivers we have, they are closed sourced so we cannot do much about it

I formatted all partitions and installed only boot.img via TWRP and the "boot partition not found" screen also has these glitches (see pic 3)

Btw, thanks for help

You'll also need to install the rootfs on the /system or /userdata partition or in a sdcard for things to work

 

[egor835]

No, no, you misunderstood me. I installed rootfs in a sdcard, then on system and then on userdata, and everything worked perfectly except for these glitches, but then I installed only boot.img, and the glitches remained. I don't think it's a video driver issue.
