Programming the GPIO Hardware on PinePhone looks complicated… But it’s not that different from microcontrollers! (Like PineTime Smartwatch and PineCone BL602)
Today we shall learn…
1. How to blink the LEDs on PinePhone
2. What’s the Allwinner A64 Port Controller
3. What’s inside the Linux Device Tree
4. How we configure and flip the GPIOs
5. How to do this in C and BASIC
We shall experiment with PinePhone’s GPIO Hardware by booting Apache NuttX RTOS on PinePhone.
Why boot NuttX RTOS on PinePhone? Why not Linux?
NuttX RTOS is a super-tiny, Linux-like operating system that gives us “Unlocked Access” to all PinePhone Hardware. Thus it’s easier to directly manipulate the Hardware Registers on PinePhone.
(Like with peek and poke in BASIC)
Will it mess up the Linux installed on PinePhone?
We shall boot NuttX safely with a microSD Card, we won’t touch the Linux Distro on PinePhone.
Let’s dive in and find out how we blinked the PinePhone LEDs…
my bluetooth headphones works great with pinebook pro, but when i connect my jack headphones audio is Quieter, without bass and with very low quality
installed OS is manjaro, i haven't tested yet other OS
I have a number of RockPro64 4Gb boards, and some days ago, after powering down the cluster one of the devices is no longer booting. I have tested it with another MicroSD and is not working either. Both MicoSD cards are booting properly on another RockPro64 device.
I have tried powering down, pressing the power button for many seconds (many times), pressing reset and pressing power button after, pressing both power and reset buttons, but no solution at all.
I see some link in the ethernet switch, that is blinking for some seconds and then turning off. Some other times it just keeps blinking for a long period of time until I press reset or power buttons, then it stops blinking definitely.
I wonder if you could give me an advice on how to solve this issue.
Waydroid is a popular Android emulation environment for Linux that uses a lightweight container to run apps. Though a release based on LineageOS 17.1 is available on many package repositories, it doesn't meet everyone's needs. The official 17.1 release doesn't support graphics hardware acceleration on the RK3399 (i.e. PinePhone Pro), which is important for usability. Additionally, the official instructions do not provide everything developers need to build a working daily-driver-ready image from the latest sources, which they may want in order to test features and fixes that they plan to upstream on their personal phones. This guide attempts to help users who want hardware acceleration but don't have it on 17.1 (e.g., PinePhone Pro users) and developers who want to test new features and fixes on their daily drivers.
I have 3 pinephones, running manjero, and mobian all 3 phones the external speaker has died, where can I get replacement speakers that can handle what the pinephone puts out. There is some kind of design flaw, or parts problem with the speaker. Rest of the phone works and bluetooth is getting better. But without external speaker can't use any alarm functions, constantly miss calls.
Since I, or maybe Mobian, or maybe both of us, fubar'd my package dependencies beyond repair a few weeks ago, I've been eagerly awaiting a new weekly. Finally dropped very early this morning, so I downloaded, decompressed and wrote the image to a known good SD card. The bad news is that the PP fails to recognize it, instead booting to PMOS on the EMMC.
I've re-burned the it several times from two different laptops, using Gnome Disks and Balena Etcher, but no joy. The only difference I see is that the Ext4 bootfs partition says "EFI".
I've never had problems with Mobian on SD... I'm stumped. Any ideas?
I have a Rock64 4GB board which I would like to turn into a FreedomBox server.
Since the Rock64 boards are no longer sold with SPI flash, I am trying
to build U-Boot to flash onto the eMMC module. I am following the instructions
for building here:
Some investigation tells me pylibfdt is not yet compatible with python3, and it will
be a while before the developers will be able to solve the problem, as it causes many other issues.
I installed python2, but I get this error:
Code:
scripts/dtc/pylibfdt/libfdt_wrap.c:154:11: fatal error: Python.h: No such file or directory
154 | # include <Python.h>
| ^~~~~~~~~~
compilation terminated.
error: command '/usr/bin/cc' failed with exit code 1
make[2]: *** [scripts/dtc/pylibfdt/Makefile:30: rebuild] Error 1
make[1]: *** [scripts/Makefile.build:398: scripts/dtc/pylibfdt] Error 2
make: *** [Makefile:2047: scripts_dtc] Error 2
What am I able to do in order to work around this issue?
For clarity, will the u-boot and FreedomBox installations exist on the same eMMC module in the end, or must I install one to an SD card and the other on the eMMC module?
Thank you for reading the post. I would appreciate any advice you have to offer.
Hi! I’ve got a spare Pinephone (Pro) keyboard case for sale because a friend of mine backed out. I don’t want it to collect dust, so I’d rather send it to one of you folks.
I’d like to have 40€ + shipping for it; shipping inside Germany or EU would be the the least hassle for me.
Cardboard box only opened once to take the photo below, everything else untouched.
If you’d like to have it, shoot me a DM. And please don’t be sad if someone else gets it, I only have one ^^
