[DEV] LineageOS 18.1 (Android 11) for Raspberry Pi 4 B

Mon Jan 04, 2021 9:59 am

Here’s my build of LineageOS 18.1 for Raspberry Pi 4 Model B, Pi 400, and Compute Module 4. It is unofficial and unsupported by the LineageOS team. It’s for advanced users only. Pi 4 model with at least 2GB of RAM is required to run this build.

I had to search for advanced restart in settings and found the setting. It's moved but it's there and it works.

I just need Open GApps to produce a 32-bit ARM build for 11... or a 64-bit LineageOS 18.1.

You don't have to search if you read the FAQ. ;)

Gapps are also discussed in the FAQ. Someone posted a mirror of the BiTGApps package to my XDA thread (https://forum.xda-developers.com/t/dev- ... t-84228785)

This solved my problem and delivered my goal of stable Sky Go playback. Your Lineage build plus Open Gapps for 11 delivers a fantastic system on the RPi. I’m even running off of a USB 3.0 stick and had no issue with TWRP.

Thanks!

Please see the picture in the FAQ.

It shouldn't be too complex thing to wire. Connect one wire to GPIO21 and another one to ground. Connect together to send key events (i.e. connect to opposite ends of a button and press it). Should be also pretty safe thing to try without risk of damaging hardware.

Looks like downloads are back in the BiTGApps XDA thread so I'll add a link to my site.

Generally speaking you can't use scripts/drivers that are meant for regular Linux distros because Android doesn't have things like Linux package management, systemd, python, etc.

I don't remember the specifics about Argon script but someone contacted Argon and they referenced this (https://github.com/Argon40Tech/Argon-ONE-i2c-Codes). There was a discussion how to use this with I2C tools included in Android builds (http://disq.us/p/2dqzkga).

You need a display that reports the resolution using EDID. I really don't have any other advice than what you can find under the relevant FAQ section.

Thanks for the build! I am trying to get touchscreen working on a Elo ET3243L. Everything works except the touchscreen part. I was in the terminal following these directions from the Elo driver readme but it's not letting me create in /etc/opt/ saying it's read only. Here is the readme link https://assets.ctfassets.net/of6pv6scuh ... e-v5.1.txt

What should I do next?

Thanks!

You would need to contact Elo for support on how to use that on Android. Nothing in that document applies to Android as it is not a 'regular' Linux distribution. Can't really comment on the what the "driver" actually is without seeing it either.

Google finds some discussion about Elo touchscreen on Android.

Hello,

I'm in trouble with a rpi4 model B that with lineage 18.1 only has video output, no tactile in my 7" screen. Any way to understand why?
i've the same screen working well in a rpi400, it's not the screen hardware..

Thanks in advance.

Please try to stick with one medium. I see this same thing posted on three different places all having slightly different information so it's really not helpful.

It really doesn't make much sense that it would work Pi 400 but not on Pi 4 with the exact same LineageOS 18 image. It seems to be an USB touchscreen. Have you tried using a different USB port on your Pi 4 in case of a hardware failure?

Sorry you are right.

I've 2 same touchpads. All working on rpi400 and not in the rpi4 model B. Tested all usbs from touchscreen and from rpi.

Perhaps your're right and it's a hardware problem..I'll try to get my hands on other rpi4 to test.
Thanks anyway,

There was another report today with a similar issue on Pi 4 vs. Pi 400 (http://disq.us/p/2f6ugcs). There's no details about the touchscreen, though. Same advice applies so try to dig through 'dmesg', 'cat /sys/class/input/input*/name', etc for more information if there's any difference between the devices.

It really doesn't make any sense why there would be any difference between Pi 400 and Pi 4. If other USB devices work, it's not likely to be a hardware issue either. If your touchscreen is powered through the same USB make sure that there is sufficient power available of course.

Is there a way to get it working with the official Pi 7" Touch Display?

Thanks! Sorted it out. Was an adapter problem. For some reason I bought a raspberry 4 model b with not oficial charger. Changed to oficial charged of 5,1V output and worked like a charm.

Thanks very much for your build!

This is such great work!! Thank you!!

I'm not sure where bug/issue inquiries are supposed to go, but I figured I'd start here.

I'm running LineageOS 18.1 on a Pi 4 (8 GB) with a 4K (3840x2160) touchscreen monitor. I noticed when I set the Display resolution (Settings->System->Advanced settings) to 2560x1440 or 3840x2160 the buttons on the navigation bar are no longer in the center of the bar. Rather, the Back and Home buttons are on the far left and the Recent button is on the far right (see image). The buttons are centered on the bar as expected when running at 1920x1080.

Is this expected?
