| Pinecil Troubleshooting |

Hi,
I used my Pinecil yesterday for a couple hours and today it stopped working. Connected to the PinePower Desktop via USB-C, it just repeatedly blinks on and off. Occasionally it will turn on after replugging, but the temperature is incorrect (shows 450 C) and the soldering tip never gets hot. I tried to flash the firmware, but the Pinecil won't enter USB mode (holding the minus button, plugging in, and releasing minus button) and the Pinecil Firmware Updater doesn't show that it's connected. Any help here would be great!
Cheers

| Baking Pi style Course for Pine64-LTS |

Hi Pine community! I'm a newbie and I'm really excited about the projects that people are doing here.
I recently got the Pine64-LTS board and was interested in delving very low-level into how the board works, how to understand the schematics and how to read the Allwinner64 datasheet. I'm interested in the Allwinner64 since I know it's used in the Pinetab and the Pinephone so my knowledge would be transferable. I saw a course
https://www.cl.cam.ac.uk/projects/raspbe...orials/os/
And it seemed like something I'd like to try with the pine64-lts. I know the chips and the board are different, but some of the things in the tutorial strike me as very possible to do, for example I should definitely be able to create a bootable image and write it to the SD card on the board and then boot into a baremetal program.
I recognize it may be a lot of work to try to find analogues to every section of this tutorial, but I'd like to give it a shot.
The first problem I was trying to figure out is the exact RAM address of the LED lights on the pine64-LTS. On my board, right next to the USB ports and the reset switches there are two LED lights. I wanted to try flashing them on and off with baremetal assembly code just like in the baking Pi tutorial. I'm struggling to relate the hookup of the Allwinner A64 with the schematics in Pine64-lts to spot exactly where this address is located.
If anybody has some hints or resources for doing this kind of reading I would deeply appreciate any links.
Thanks in advance!

| Synchronizing: How do you sync / synchronize Calendar and Contacts with your desktop? |

Happy Easter holidays to all of you!
Is it possible to synchronise the calendar/contacts on the Pinephone with your Linux desktop?
The easiest way would of course be to connect the calendar/address book to an online account – but I do not want to give the data of my friends to Google or any other corporation just in order to move it from my phone to the laptop right next to it.
I have come across two possible solutions: I could set up a Nextcloud server (which is probably immensely complicated, way too complex for the tiny task intended and which may not work) or use KDEConnect (of which I don't even know whether it works on the Pinephone).
Is there any simple way to do it? The company Palm, which used to produce so-called palmtop computers, apparently had a small desktop program called "HotSync" that one could start on the desktop computer and it would synchronise calendar, contacts and files via bluetooth or cable. Is there anything equally comfortable for Linux? And if not: What would would the complicated solution look like?

| Battery gauge issue (mainline kernel) |

Hello,
I'm trying to use Debian on a Pinebook Pro using the official bullseye installer. (I'm aware of the unofficial installer!)
Mostly, it works quite well! For the record:
* the installer created an additional partition (dummy partition to protect the bootloader, maybe?) that confused u-boot; deleting the partition fixed the problem (I plan to reproduce the unofficial installer's nice partition scheme later);
* the screen remains blank (I installed using a serial cable) because the kernel gets confused by the video + usb-c port; this can be worked around by removing
Code: &cdn_dp {
status = "okay";
};
from the .dts (in the kernel sources), rebuilding the .dtb, and inserting the .dtb in /etc/flash-kernel/dtbs. (Information from https://www.reddit.com/r/PINE64official/...ne_kernel/ );
* the battery gauge is not working (this is the reason for this post);
* there is something wrong with the audio output, which I have not investigated (the uart/audio switch is set to uart, for serial output, it would make sense to try setting it to audio first).
From dmesg, I see a few messages related to the battery gauge:
Code: [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034]
[ 0.000000] Linux version 5.10.0-3-arm64 (debian-kernel@lists.debian.org) (gcc-10 (Debian 10.2.1-6) 10.2.1 20210110, GNU ld (GNU Binutils for Debian) 2.35.1) #1 SMP Debian 5.10.13-1 (2021-02-06)
[ 0.000000] Machine model: Pine64 Pinebook Pro
(snip)
[ 7.150366] power_supply cw2015-battery: Not all required supplies found, defer probe
[ 7.150384] cw2015 4-0062: Failed to register power supply
(snip)
(The two lines about cw2015 are repeated a few times, later.)
My understanding is that cw2015 support has been mainlined and should work with a mainline kernel. I don't really understand what the "Not all required supplies found" message is about, but dmesg does not seem to have errors relating to the DC input not the USB-C input. This is the only occurrence of "power supply" in these messages.
The same errors appear with the original .dtb file, so this is not a side effect of the above change.
Do you know what is causing the cw2015 driver to fail? Any suggestion for a fix or workaround would be highly appreciated!
Best regards,
Lionel

Hello guys!
I've got curious, is it possible to ship Pinephone to Russia ? (getting to Saint-Petersburg and taking it manually from Finland or other country is not an option). Also I'm interested is there anybody from Russia who's already got Pinephone and how did you get it ?
P.S. I've heard that it's possible to deliver PinePhone to Russia despite local cryptographical restrictions if parcel is marked for personal usage, is that true ?
