It's a bit of a hike to get to the end of compiling and installing, but once done, box86/WINE performs admirably on the PP Community phone/physical keyboard.

In xfce (though not in Manjaro Phosh, oddly), LibreOffice has laggy typing, but Word 97, despite its 20-second start-up, has none, and once the program is up, it's as robust as anything on the PP. All its features function and it works with the phone's suspend.

HanDBase, my favorite cross-platform database app, also does its job.

I installed an NVMe drive into my Pinebook Pro. I booted into Majaro from a MicroSD card, blew away the "ROOT_MNJRO" partition from the eMMC drive, and then use the Manjaro flash utility to flash Manjaro Arm for Pinebook to the NVMe drive. On reboot, I completed the setup, rebooted, and then there's no wifi, no audio, connecting my USB ethernet dongle doesn't get recognized, even the power button doesn't work. *UPDATE* The power button does work now.** If I flash this image to the eMMC drive, everything works fine. The same image works fine from the microSD card. For some reason, only when I flash the image to NVMe do I lose all of the functionality of the Pinebook Pro, though I can open a terminal and folders. Hoping someone here can point me in the right direction.

I've been trying to write a Python application for the Pinephone that needs access to the camera.

1. My first iteration was using python-opencv, but that doesn't work out of the box.
The simple first two lines:
```
import cv2
cap = cv2.VideoCapture(0)
```
produce the following error:
```
[ WARN:0@18.736] global ./modules/videoio/src/cap_gstreamer.cpp (2401) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module v4l2src0 reported: Device '/dev/video0' is not a capture device.

[ WARN:0@18.758] global ./modules/videoio/src/cap_v4l.cpp (902) open VIDEOIO(V4L2:/dev/video0): can't open camera by index

```
There is some discussion about this problem in a manjaro forum: https://forum.manjaro.org/t/access-pinep...encv/94593
but there are no conclusive solutions.

I have two possible work-around to this issue:

2. I could build a python library reusing "megapixels" code (https://gitlab.com/postmarketOS/megapixels). By the way, there is a very interesting description of the pinephone camera interface in the README in that repository.

3. Or I could call an external command from my python executable that gets me the actual camera data, for example `ffmpeg` similarly to this blog post: https://blog.brixit.nl/camera-on-the-pinephone/

In my opinion, solution 3 is ugly and probably under-performant, while 2 seems overkill.
There should be a simple way to read the camera data natively from Python.

If anyone can give me a solution or a hint, I would really appreciate it.

Hi everyone,

my Pinetab2 suddenly stopped working after around 4 weeks of minor usage.
The main symptom is, that the display stays complete black when trying to power on.

As Pine64's support is unfortunately not very helpful and pointed me to the community, i'd really appreciate your help.

I was able to get the following out from UART-console:

I do not know if this could be hardware issue, OS (Manjaro) or anything else?

Thank you for advice and suggestions.

PS: I've just noticed this post with similar, possibly the same issues https://forum.manjaro.org/t/usb-port-bre...sue/139653

Testing a new Operating System like Apache NuttX RTOS (or Linux) can get painfully tedious on a Single-Board Computer… Swapping, reflashing and rebooting a MicroSD Card, again and again and again! (Like how we tested NuttX on PinePhone)

Thankfully there’s a better way: Booting NuttX (or Linux) over the Local Network, with U-Boot Bootloader and TFTP!

Today we’ll configure TFTP Network Boot on Star64, the new 64-bit RISC-V SBC. (Powered by StarFive JH7110 SoC)


Star64 JH7110 RISC-V SBC: Boot from Network with U-Boot and TFTP

SOLD *** SOLD *** SOLD

Owned for about 3 weeks, in factory condition w/updates. In new condition.  Small scratch on screen is on screen protector (that's what it's for), not screen. I do not have the original box.

I have too many projects and this is just a victim of my needing to focus.

US only, please. Ships from Washington, DC area.

The R4 resistor in my pinecil has failed, when I insert a dc jack I can see a tiny spark in a tiny crack inside the resistor. Is this likely to take down anything else hardware wise, like the mosfet directly in front of it?

Hello,

today I tried to boot my PinePhone Pro, but it doesn't boot.
- Battery is charged (used external Charger, bought new battery)
- I can connect it to my PC and see the device in MASKROM mode
- no led or vibration is noticable

Trying to boot the phone connected with UART got me following lines.
