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
-app

Thank a lot for your feedback

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)

(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.

In these days, I play around with different kernel configs and patches. While doing so, I collected data about the star64's speed.

Build time Fishwaldo's kernel 5.15.107:

Hi guys,

So I had Manjaro installed on my eMMC for a while now and I wanted to switch to Fedora.

I went to the official Wiki which redirects us to a blog post from 2021 which I followed.
I flashed the firmware to the micro SD Card

There are quite a few possible variants of the installation process. Below instructions do not require a serial console. All steps are performed on a linux pc and not on the star64.

• If you have a 8GB board, apply the patch from here https://forum.pine64.org/showthread.php?tid=18263
  
• If you want full GPU support then apply the patch from https://forum.pine64.org/showthread.php?tid=18301 and also follow the firmware installation step (possibly after a first boot into the star64)
  

Sad reality, but video out on pinebook pro was regressed on all major distros

this includes default factory os manjaro

Found some info that kernel patches needed to allow video out were dropped since were hard to maintain



I guess with years interest for PBP dropped, as well as support for basic functionality from developers.

For example, cannot believe that in 2019 there was mrfixit debian build with all the working functionality that you could easily flash to sd card, while now 4 years later you cannot connect pbp to external monitor or tv


Any suggestions how to make it work again would be appreciated

I have read that one can use telnet and ssh to access the Pinefone on a network. That is by command line. Is it possible to make the folders and files of the external microSD card available as shares using Samba or similar so that complex file management can be done using the GUI file management tools of a laptop OS? If so, how does one do this? If not, what options are there?

What i would like to do is view documents on the Pinephone and sort then into folders which i would then transfer back to a laptop for further management. The included file manager in Phosh Portfolio does not allow easy moving and sorting of documents. Are there other file managers that are phone friendly that provide the described workflow? I have thousands of documents to sort and doing some of this on the Pinephone when i am traveling without my laptop would help save time.
