Hi,
please, I need some help to make a vibration signal, if possible with adjustable vibration-length, out from a Python programme from a Raspberry Pi 4 via bluetooth connection.

Best regards,
Gerald

I am running Armbian 23.02.2 and I am trying to use OpenCL.

Using clinfo, it turns out that there are no installed driver.

Here's my Star64 booting up Armbian for the first time on a 2GB microSD. https://youtu.be/3L0rNewF0QE
This Armbian image is based on Fishwaldo's kernel & device tree and this release of Armbian: Armbian_23.5.0-trunk.275_Star64_lunar_edge_5.15.0.img from here: https://www.armbian.com/star64/
I made an image of my 2GB drive in case anyone wants to write it to a microSD and try booting it. I'd recommend writing it to a larger microSD, maybe 16GB or more, because my 2GB quickly filled up. Armbian should automatically resize itself to fill your larger microSD.
You can find the compressed disk image on google drive: https://drive.google.com/file/d/1zIOl9xU...sp=sharing The shasum for the xz file is 4a1dc00d0ac27c690a04546c4447f6f96fe5f38f.

Is there an equivalent for the RHEL/Fedora emergency shell boot for Pine Pro/Manjaro ARM/Plasma?

I've tried various key combinations including ctrl-shift-F2. Inserting a USB having burned a downloaded Manjaro-ARM-kde-plasma-pbpro-20.12.img.xz image onto it does nothing.

Been using linux (mostly RH, Fedora and Ubuntu) for nearly 30 years; ARM (Chrome OS) for six months. I can't say I'm terribly impressed with the Pinebook. And this from a guy who's partial to KDE/Plasma.

System is stuck, by the way, on (not) mounting a 2TB sd disk whose PARTUUID I'd inserted in fstab. Meant to comment out the line when a manual test mount didn't work, but must have somehow not saved the file after inserting the hash character. Stuck on it whether the sd is in or out.

Oh well. Appreciate any help. A search on the forum turned up no results that I could see.

hi my pine phone is not starting , maybe i can repair it if installing an image working and using ubuntu. is it possible?

hi there, i bought the phone some days ago , was updating the phone , when a message asking for continuing with the installation [s] r [n] but the keyboard dissapeared and the screen was zoomed. so i wasnt able to continue, then i restart the phone. But now is not booting, only appears the "K" logo moving then stops and appears the mouse. I tried to hold the volume up and power buttons but then again appears the k logo and the mouse again.
If you can help me

Here's a graph that shows the effect of L1 and L2 caches.

Hi all,

I have bought my pinephone and use it daily.

I'm looking for better battery life.

The only way what i heard, it's reduce the power on time screen.

What can be a manner to have better battery life in general and espacially when the phone is on and active ?

What's the main difference with an android device !

For me, three component are main battery consumer.

1-CPU : Allwinner A64 4 x ARM Cortex A53 cores @ 1.152 GHz
2-Modem : Quectel EG25-G with worldwide bands


*****
1-CPU
*****
I have tried to power of two or three core -> no impact
not again tried to minimise frequency ! -> any feedback ?

The firmware is opensource ?

********
2-MODEM
********
The only thing what i can do is to flash opensource firmware of modem.

The opensource firmware URL : https://github.com/the-modem-distro/pinephone_modem_sdk


I don't know if this FOSS firmware drain less battery than stock firmware !

Have you a power consumption mesurement method ? It's powertop ?



I used this script to have notification with 3G/4G connection to keep connection with XMPP/Matrix client. And modem restart when modem disconnected.

Thanks a lot for your feedback.

I have bought a pinephone and the battery consumption is too high.

As i good understand, pinephone have a SoC AllWine A64 and that's why it drain a lot of battery and warm.

The advantage of this SoC is good supported linux mainlines.

With the pinephone pro, the Rockchip RK3399S SoC is an ARM. In theorical, it drain less battery.
It's right ?

What is the level compatiblity of pinephone pro with Mobian OS ?
-linux mainlines
-basic features
-drivers
