This presentation explains how we built the NuttX Drivers to support Touchscreen Apps on PINE64 PinePhone:

(1) MIPI DSI on Allwinner A64 SoC
(2) Allwinner Display Engine
(3) Goodix I2C Touch Panel
(4) Integration with LVGL Graphics Library

To derisk the development, we prototyped the NuttX Drivers in the Zig Programming Language, before rewriting to C.

Hello all!

My PBP arrived today. unfortunately… it appears to be dead on arrival. The power button did nothing. I plugged it in and that didn’t help. I tried holding down the power button. All that I have to go off of is a red LED indicator that comes on when I plug in the charger. Anything I should try? What do I do?

Hi all, this might be a daft question, but does anyone know of a screen that's readable in direct sunlight that can replace the pinetab screen?
I'm ideally looking for something brighter than the ipad pro (1600 nits), and ideally more like 2000 nits (like the samsung UDR 2000 displays, or DJI's CrystalSky monitors although I've no idea who manufactures their screens, or Gemlighttech's 3500 nit displays).

As I understand it, 1 nit = 1 candella per square cm.

My thanks for any thoughts anyone has on this.

If there's another open-source tablet with a more customiseable display I'd also gladly accept a steer.

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?
