Smartphones are incredibly complex gadgets. What if we could learn the internals of smartphones... By booting Apache NuttX RTOS on our phone?

Over the past year, we have ported NuttX to PINE64 PinePhone as an Educational Experiment. Today we can run NuttX Touchscreen Apps on PinePhone, based on Allwinner A64 SoC with Arm64 CPUs.

NuttX on PinePhone will soon support Phone Calls and Text Messages on the 4G LTE Network. We hope NuttX will become a valuable tool for teaching the inner workings of modern smartphones.

Hi all, I'm not sure where to post this. I'm finally selling my Pinebook Pro. I wrestled with it over the last couple of years and tweaked it to where I want it to be, aaand now I don't really need a laptop anymore. 

It's here on ebay - and I included a lot of photos and several screenshots of the system running.

                   
I succesfully installed a Western Digital Blue 500 GB NVMe SSD drive. It boots from the SSD and doesn't seem to exhibit any extra battery drain. Manjaro ARM is already installed to the NVMe, and should boot right up to Manjaro's first-time setup wizard. I advise running an OS update immediately though, Manjaro likes to stay current.

I flashed Tow-boot to the SPI and now the bootup experience is infinitely better. It's a total improvement in my opinion. As most of you know, if there's an error in your boot media the laptop is normally unresponsive and inert, you don't even get a power light. With the new SPI boot image, it acts like a normal laptop. If there are any errors in the normal boot sequence, you'll still get a power-on light and the boot menu. From there you could boot from a rescue disk however you like.

The old eMMC was removed long ago. Not really needed with the NVMe working anyway. And the device boots perfectly from microSD as well. If you really need an eMMC they're pretty cheap, but I haven't ever felt the need for one. Too small and too slow.

I do not have the original slow barrel charger. I've been charging it with any USB-C charger for the duration that I've had it. It seemed so much faster.



Feel free to ask me any questions!

I have a Pinephone 3GB/32GB which is able to playback videos of DVD quality (720x480px) or less.
Even then it starts getting hot pretty quickly, I won't watch longer than 20-30 minutes.

Is the PPP able to play videos in Full HD (1920 x 1080px) and if so, does it also become hot quickly?
(I'm referring to the file's resolution, not to the display).

If there are differences between distros, which one performs best?

Thanks!

Can the layout of the virtual keyboard be changed on the Arch Linux (danctnix)? I need arrow and escape keys.

Would be *GREAT* if we could get official forum updates at least quarterly   !!!

Is there a way to check whether tow-boot is installed or not?

Hello,

I have been trying to get adb to work on my Pinephone. The current UBPorts build ships adbd:
    https://gitlab.com/ook37/pinephone-pro-d...=heads#L31

My understanding is, that "Developer mode" and switching to/back from it is taken care od by usb-moded:
    https://gitlab.com/ook37/pinephone-pro-d...=heads#L38

This requires configuration, as documented in https://gitlab.com/ubports/development/c...wikis/home

My current problem is to find these configuration values for the PinePhone(s). Ideally for all editions.
I have tried looking through the forums, this is what I found:

* https://forum.pine64.org/showthread.php?tid=16087
This thread seems to end with "you shouldn't want adb anyway", but that doesn't really answer my problem: I do want to enable adb, and I think I should be able to.

I thought I might be able to pull this configuration from an AOSP image, since it seemed like the PinePhone Pro came with one pre-installed.
I have looked for it in this thread: https://forum.pine64.org/showthread.php?...705&page=2 but as mentioned in the last message, the links are now dead.

I have also looked for it in both
https://wiki.pine64.org/wiki/PinePhone_S...e_Releases
and
https://wiki.pine64.org/wiki/PinePhone_P...e_Releases

Neither page seems to have it. pine64-pinephone-plamo-beta-factorytest.img.xz is a postmarketOS image

So my questions are:
- Where can I look for these configuration values?
- Does anyone have an AOSP image for any of the PinePhones?

I can install ok and it will start up, and soon will message updates are available, and as soon as I install the updates from software manager or from console, my pinephone will give a bunch of error messages but not boot anymore.
Is KDE Plasma mobile abanoned by Manjaro, or does nobody care about?

Hello,
First post on the forum and I'm new to Linux, but crash-coursing so there will probably be a lot of basic questions. I'll try to give as much background as I can.

I purchased a Pine Phone Beta edition with convergence package. I settled on Manjaro Arm Phosh beta 34 for the distro. And I'm on the Metro PCS ( T-mobile network) in the U.S. So of course that means I have call, SMS, data, but no MMS. 

I read through the article on how to set up Fractal through terminal (https://wiki.pine64.org/wiki/PinePhone_MMS_with_Matrix), but I'lll be real-- I was totally lost. I've run a few commands through terminal (like looking for clogged sms and clearing them), but without step-by-step guides or a DIY video I was lost with all that. So given the quick pace of distro development I opened Fractal and tried to set it up from there-- hoping for the best. 

Fractal prompted me to create an account and directed me to Element. I did that. Element asked me to download Element apk from fDroid. I think I did that, but I don't see it on my phone. So then I went back to Fractal and tried to log in. When Fractal prompted for my "provider," I listed my identity server ( vector.im which according to Element doesn't support phone numbers ). I entered my login info for Element, but I keep getting " Can't Log in " in Fractal. I've tried both Username and @username:matrix.org and of course Password. I even tried the Manjaro username and password. 

What am I doing wrong? Do I need to go back to Terminal and type a bunch of commands?  

Thanks in advance.

I cracked my (original) Pinephone screen and got a replacement. Installation seemed ok, and I snapped the back frame on and put in the battery to make sure everything was ok. Booted, unlocked, logged in, great.

So I replaced the 15 screws and snapped the back cover on for more testing, and after a short while, the screen wouldn't wake up. I plugged it in to my computer USB, and the pinephone was recognized, so it's running, motherboard working, daughterboard working, just no display. I assumed I made a bad connection and disassembled and detached, cleaned, and re-attached the display cable. Snapped the back frame back on and put in the battery and all was fine.

Again, I replaced the screws and rechecked. Now the screen doesn't seem to unlock. On a very close look, it seems the backlight comes on but the display itself isn't responding.

Repeating the process, everything seems to work, including the display, until I install the back frame screws. WTH am I doing wrong here? I don't think I'm over-tightening the screws -- I don't even know why that would be a problem.

What's going on here? Why does the screen work until I screw down the back frame? What do I need to do to get my phone up and running while fully assembled?

Ideas? Thanks!
