I'm working on a custom OS in Zig for the PinePhone v1.2b.  I am struggling to find some documentation on various parts of the hardware.  Today the compass.  I tried the I2C address for the AKM compass, and no response, so I am hoping I have the VTC compass, otherwise my TWI1 code is doing something very wrong 

But I dont have the I2C address, and the documentation linked from the component page on the wiki has expired.  Can anyone shed some light on this please.  A good start would be the I2C address, but a copy of the data sheet would be best please.  I am unable to decode linux source tree structure to find this.

Also, are the PinePhone sensors always powered, since DLD01 seems to be used everywhere.  For the LCD and touch I had to switch on some pio pins, but I dont see that on schematics, only EINT pins.  Iḿ worried about power usage from unused sensors.
I am used to following @lupyuen  amazing tutorials, but I think he focuses more on new devices and didnt cover the sensors

I have a Pine64 PineTab2 device. I have accidentally destroyed the Linux kernel on it, and there is no way to boot into Linux. However, I can access U-Boot. What should I do to install Arch Linux ARM with U-Boot only?

By the way, I am not familiar to U-Boot commands. Are there any suggestions for installing Arch Linux ARM? (especially U-Boot commands)

This newly released operating system outperforms FydeOS's ecosystem with broader support and is specifically designed for low-power PCs.

Hi,
I wrote a Kivy app on my mobian pinephone (phosh). Main screen is just 3 buttons and a label.
If I switch to another app, the touches on the display are still sent to the kivy app. 
Even if the display is turned off, the touches on the black display are sent to the kivy app...
Is that behavior expected?
How to avoid this?
Best,
Jean-Charles

Now as easy as sudo pacman -Syu
Try it out, Bluetooth is now active for me, paired my BT mouse and it works!

No cameras yet...
I am also trying to get a USB NMEA receiver to work for in-car navigation.

So this will allow use of bluetooth stylus as a touch mouse with left-click now?
If so which styluses are compatible?

is this driver/hardware currently compatible with BT-low energy?

"Someone recently managed to get on a Microsoft Teams call with representatives from phone hacking company Cellebrite, and then leaked a screenshot of the company's capabilities against many Google Pixel phones,"

"The Support Matrix also shows Cellebrite's capabilities against Pixel devices running GrapheneOS, with some differences between phones running that operating system and stock Android. Cellebrite does support, for example, Pixel 9 devices BFU. Meanwhile the screenshot indicates Cellebrite cannot unlock Pixel 9 devices running GrapheneOS BFU."

Hello,
The PinePhone automatically powers on when plugged in. While I know there are workarounds and suggestions like "using a better charger," I’m not interested in those.

What I’d like to know is:

Is there a command I can enter in the terminal to prevent it from doing that, so it only turns on when I press the power button?

I have a 64 G eMMC that came with my Pinebook pro and I decided to upgrade to 128. I got a new one here from pine64 and also the USB adapter. My plan was to use the USB adapter with the 128 G drive and do a dd copy from the existing drive to the new one, then swap them out. I understand that there may be some UUIDs or some other values I will need to change, but before I start messing around and killing a weekend I thought I would ask around and see if my general plan is sound.

Any problems I should look out for or other friendly advice anyone wants to give?

(I also got the audio-serial adapter to debug things when it DOES go wrong)

Hi,
I have written my first Kivy app for my pinephone running latest mobian. I run it launching it from a console...
I spend half a day wondering how to add an icon for it on my phosh phone and did not found any documentation about that topic.
Do you have any doc or pointer?
Thanks
Jean-Charles
