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

Zig Compiler works great for compiling C Libraries into WebAssembly. Can we preview an LVGL App in the Web Browser… With WebAssembly and Zig Compiler?

Let’s find out! In this article we’ll…

(1) Run a Zig LVGL App on PinePhone (with Apache NuttX RTOS)

(2) Explain how Zig works with WebAssembly (and C Libraries)

(3) Compile LVGL Library from C to WebAssembly (with Zig Compiler)

(4) Test it with our LVGL App (in Zig)

(5) Render Simple LVGL UIs (in Web Browser)

(6) Later we might render LVGL UI Controls (with Touch Input)

Check out the article…

(Possibly) LVGL in WebAssembly with Zig Compiler

My new Pinephone 64 arrived today. I finally was able to do the Setup routine; it's not at all intuitive. I was able to make a call, so it connects with the network (Koodo in Alberta, Canada) OK. But I cannot get it to "see" the right time and date. Got the region set to America/Canada/Edmonton, so the time zone ought to be MOuntain Daylight time. Phone thinks it's something 3:15 A.M. on May 22, 2022. I know that ain't right. I have time/date set to automatic, so should it be pulling that off the cell tower? Changing time/date to "manual" didn't work, because I cannot make the wheels on that slot-machine display move in any sort of rational fashion by using the touch screen. I plugged in a keyboard via the hub, and was able to type letters and numbers into some fields, but the rolling number boxes for time/date are impervious to that. And my couple of hours of fruitless groping ran the battery down from 98% to 38%, so I have it on charge again.

It's running on the software that was on it when it came out of the box. No update as yet.

I have been trying to get a DVD drive to work with the RockPRO64, but for some reason the kernel is not properly operating the drive and the open/close button does not work.
I researched the problem, and it seems like this is a general problem with the Linux kernel or its modules on multiple architectures — some versions of the "linux" package in Manjaro/Arch properly provided CD drive support and some did not. So, now I simply have to compile kernels from source until I get the right one.  [2]

The only problem is, after a week or so of trying to compile kernels and comb through source code for rockpro U-Boot packages I still have no idea how to compile a kernel for U-Boot that actually boots. I have tried "mkimage" and putting a regular compiled kernel stripped of debug information into mkimage, but the kernel always fails to boot and restarts the CPU. I read and re-read the documentation for the U-Boot packages and saw that I'm apparently supposed to have a kernel tree with "make uImage" or "make pImage", but none of the kernel.org trees had this so I'm not sure where to get this source tree.  [1]
I am also confused where the blobless package "uboot-rockpro64-foss" finds the kernel if it does not install one to /boot, or in any case where my kernel is on disk after I boot into a Manjaro partition.

How do I compile a kernel from source into an "Image" file loaded by extlinux.conf?
Is that even the same kernel that loads when I boot my eMMC and run "uname -a" to describe the kernel? How do I compile and use a new one?


[1] edit 6/07: so, apparently new kernel trees have "make Image". I tried this with kernel version 6.4.0-rc4 and it did not boot past what seems to be the Secondary Program Loader (SPL).

[2] edit 6/17: well now I feel really stupid. The problem with the DVD drive was that I kept trying to plug it into a USB 2.0 port and it really needed a USB 3.0 port. I just never figured this out because I always had something else in the single one the ROCKPro has.
That said, it would still probably be helpful to people to know how to compile a kernel, so I will still test it if anybody figures out how. I have already been messing with creating distro images for a while now.
