  Pinephone time goes too slow (not a 2115 year problem)
Posted by: grwlf - 02-04-2022, 02:03 PM - Forum: PinePhone Hardware - Replies (1)

Please help me to figure out what is going on with the system time of my Pinephone. I noticed that both system and hardware clocks run too slow for some unknown reason. For example, I could see that NTPD adjusts the clock every several hours.

I wrote a script collecting 3 kind of times: the network time (from time.nist.gov), the system time and the rtc (hwclock) time. Then I did:

1) Stop ntpd
2) Run this script  for about a day on my desktop PC and on a Pinephone (Pinephone was in a suspend most of the time)
3) Collect the data and plot the results this renderer

The results are:
[Image: clockskew.png?raw=true]
Vertical axis is the time difference, in seconds
Horizontal axis is the running time of my script, in minutes
The blue and orange lines show the difference between remote (time.nist.gov) and local clocks: system and hwclock.


As we may see, the clock skew tend to increase quickly on a pinephone.

The question is - why, and how to fix.

Note, that it is unlikely a known "year 2115" problem, because I can see both errata and the correction patch applied to the kernel.
Note2, I did stop NTPD, so I can't explain right now why the pinephone time difference became zero at 450th minute of the measurement. Maybe there is other agent which does the correction, besides ntpd.

I use Megi's kernel 5.13.7, Crust fw is 0.4, the os is MobileNixos.

I believe it is a hardware/firmware problem. Let me know if there is a better place to post it.


  Gnome-podcasts on Debian repos
Posted by: user641 - 02-04-2022, 01:52 PM - Forum: Mobian on PinePhone - Replies (4)

Is the gnome-podcasts coming to the Debian repos soon? I feel really bad using flatpaks, or is there an alternative to using another app? I tried gpodder but it is not mobile friendly and I had to download each episode than play it iwth another app, not very practical...


  compiler wev
Posted by: oihantto64 - 02-04-2022, 11:55 AM - Forum: Arch Linux on PinePhone - Replies (3)

To adapt the pinephone keyboard, I will need to use the equivalent of xev for wayland ie wev, or the version available on AUR is not suitable for arm64. Is it difficult to adapt the pkgbuild to compile compatible with aarch64?


  Keyboard battery reporting accuracy
Posted by: brb78 - 02-04-2022, 11:12 AM - Forum: PinePhone Pro Accessories - No Replies

Anyone else have a KB that seems to be connected properly (input received, charge passed to "main" battery, "kb151" detected in power submenu of gnome-setting) but that insists on reporting it is always at 0% charge, even when there is no external power connected and the main battery continues to charge up (presumably off the not-0% KB battery)?

on Arch/Phosh

Code:
># ppkb-i2c-charger-ctl info -v
Charger: Full ( chg_end)
Button: 00 ( btn_not_press)
0x70: 19
V=4184 mV (OCV 4210 mV) I=-6 mA


  Lost internal earpiece
Posted by: Veraendert - 02-04-2022, 10:10 AM - Forum: PinePhone Hardware - Replies (3)

Hi everybody. It's been a while but i now have reactivated my PP. Sadly, somewhere along the way, i seem to have lost the internal earpiece. Not in the "oh, there must be some misconfiguration"-way. The piece itself is gone missing. I already bought a new screen but that doesn't include the internal earpeace. Does anyone happen to know which spare part i should grab? It doesn't seem to be available from the store. Thanks in advance.


  Keyboard Case Not Typing in Mobian
Posted by: thismarty - 02-04-2022, 09:31 AM - Forum: PinePhone Pro Accessories - Replies (5)

Keystrokes on my keyboard case are registered on my PPP in Manjaro BUT keystrokes are not registered on the official PPP build of Mobian (January 16 daily).

Since Mobian is listed as one of the OS's that should support typing on the keyboard case, I assume it should work.

I've ...

1.  Updated, upgraded, dist-upgraded, and re-flash the SD card

2.  I've re-seated the keyboard

3.  I've POGO-shimmed the keyboard


Yet no matter what, Mobian doesn't seem to hear my keystrokes from the keyboard, while (notably) Manajaro does.

Any suggestions?

TIA!


  Keyboard Not Charging PPP
Posted by: thismarty - 02-04-2022, 09:25 AM - Forum: PinePhone Pro Accessories - Replies (7)

My keyboard doesn't seem to be able to charge my phone.

Here are some data points:

1.  I've pressed the button - quickly, held it for 20 seconds to shut it down, pressed quickly again, and various other combinations. 

2.  I see the charging bolt in the battery icon in the GUI (in both Manjaro and Mobian).

3.  The Power panel in the OS Settings indicates that the second battery is there (but at 0%).

4.  The phone discharges its battery at the same rate with or without the keyboard attached.

5.  I tried the shim trick.

6.  I've tried several properly-rated chargers directly in the keyboard USB-C port.

7.  I've not made the mistake of plugging a charger into the phone whilst it is seated in the keyboard case.


It would appear that the root problem is that the keyboard simply won't charge.  It seems to be present electronically and recognized by the OS, but just empty - despite my having 'charged' it.

Any suggestions?


  soundcard pinephone mobian
Posted by: benedikt55 - 02-04-2022, 07:55 AM - Forum: Mobian on PinePhone - Replies (4)

hi, I'm new here and more and more happy with my pinephone, just awaitng the keyboard next days.
I'm using the phone as my daily driver and even the camera is somehow charming.......having its own character.....
I' m a DJ( ....exp. rock, noiserock......) and have the pinephone used for DJing, which is running quite o.k., due to Lollypop and the docking- board.
Now I'm wondering if it is possible to connect an external soundcard to the pinephone?
Which one you would recommend.......a real good one?
Thank you!


  Guide to power off the Pinephone on low battery
Posted by: Ulfnic - 02-04-2022, 05:29 AM - Forum: General Discussion on PinePhone - Replies (1)

I wrote a low-power-off BASH script for the Pinephone and Pinephone Pro to help prevent over-discharge by forcing a power-off below a certain capacity.

It loops through all power sources the kernel is aware of and enforces a minimum capacity rule that powers off the system if a battery is below a certain threshold (default: 5%) and not charging.

It just needs something to run it every minute. I've included a Systemd setup guide but OpenRC (PostmarketOS), chron, ect will work just as well.
