  PineNote v1.2 - Charges Never Enter "Charging" State (Factory OS, RK817 Below Minimum
Posted by: ttsp - 10 hours ago - Forum: General Discussion on Pinebook Pro - No Replies

I'm looking for help determining whether this is a software issue (kernel/device tree/RK817 driver) or a hardware failure before pursuing an RMA.
Hardware

  • PineNote v1.2 (Community Edition)
  • Original factory-installed OS (never replaced or reinstalled)
  • Current kernel:
    Code:
    6.12.11-pinenote-202501281646-00249-g211ba27556cc
  • Installed kernel package:
    Code:
    linux-image-pinenote-stable 1.7
Timeline
The device arrived with approximately 40% battery.
I never installed an alternate operating system. The charging problem occurred on the factory-installed OS within the first day after unboxing.
The device operated normally from its initial battery charge but never successfully charged from any charger.
Eventually the battery discharged to 0%.
The interesting part is that the PineNote still boots and runs normally when external USB power is connected. I can SSH into it and run diagnostics. The only failure appears to be that the battery never actually charges.
Chargers Tested
I tested all of the following:
  • OEM USB-A ↔ USB-C cable
  • USB-A wall charger
  • USB-A laptop port
  • 65 W USB-C PD laptop charger
Behavior is identical with every charger.
When powered off and connected to power, the charging animation appears on the display.
I also left it connected overnight while powered off.
Battery level remained at 0%.
USB Issue
Initially the device was affected by the USB issue described in PNDeb Issue #106.
After applying the recommended fix:
Code:
lsusb
works normally.
USB connectivity appears completely functional now.
Charging behavior did not change.
This makes me think the USB problem and the charging problem are unrelated.
Diagnostics
Battery state:
Code:
cat /sys/class/power_supply/rk-bat/uevent
Relevant output:
Code:
POWER_SUPPLY_STATUS=Discharging
POWER_SUPPLY_CAPACITY=0
POWER_SUPPLY_CURRENT_AVG=-168560
POWER_SUPPLY_VOLTAGE_AVG=346xxxx
The important point is that the battery never transitions to:
Code:
POWER_SUPPLY_STATUS=Charging
even while external power is connected.
Charger state:
Code:
cat /sys/class/power_supply/usb/uevent
Relevant output:
Code:
POWER_SUPPLY_ONLINE=1
POWER_SUPPLY_USB_TYPE=Unknown [DCP]
POWER_SUPPLY_VOLTAGE_AVG=452xxxx
So Linux clearly detects external power.
Kernel messages:
Code:
dmesg | grep -i rk817
produces repeated messages similar to:
Code:
rk817-charger: Battery voltage 3465880 below minimum voltage 3500000
rk817-charger: Battery voltage 3477640 below minimum voltage 3500000
rk817-charger: Battery voltage 3483240 below minimum voltage 3500000
I do not see any other charger-related or battery-related errors.
Package Status
Kernel package is already current:
Code:
apt update
apt list --upgradable
apt policy linux-image-pinenote-stable
No newer PineNote kernel is available.
What Seems to Be Happening
From everything I've observed:
  • USB is functioning.
  • External power is detected.
  • Charger is detected (
    Code:
    ONLINE=1
    ).
  • Battery is detected.
  • The device boots and runs on external power.
  • The battery never enters the
    Code:
    Charging
    state.
  • Battery voltage remains below the RK817 minimum threshold (~3.5 V).
  • The battery never recovers, even after being connected overnight.
Questions
  1. Has anyone seen the RK817 refuse to perform pre-charge when the battery falls below approximately 3.5 V?
  2. Is there a known device-tree or kernel configuration issue that could prevent pre-charging?
  3. Is there a way to determine from software whether the battery protection circuit has tripped?
  4. Are there any additional diagnostics I should collect (debugfs, I2C register dumps, RK817 register reads, etc.)?
  5. Does this behavior point more toward a failed battery or charging hardware than a software problem?
Any guidance from people familiar with the RK817 charger implementation or PineNote power management would be greatly appreciated.

Hello,
While don't get me wrong, the image of the little flower pot is pretty, I would like to be able to do some more unique customizations. Thank you for any help in advance!

  Fix Bricked SPI Flash, Pinephone Pro
Posted by: FR_IV - 06-27-2026, 05:00 PM - Forum: PinePhone Pro Hardware - No Replies

Hi!
A couple weeks ago I was trying to write Tow-Boot to my Pinephone Pro's SPI Flash. It worked once, so I know that the SPI device is connected and functional. However, (unrelated to the Tow-Boot install) I messed up the Manjaro-Phosh installation I had previously installed on the Pinephone pro, so I reinstalled Manjaro-Phosh which removed Tow-Boot from the SPI flash. I tried to rewrite Tow-Boot in the same way as before, but it got stuck and I forced the Pinephone Pro to power-off. I then tried to write Tow-Boot again and I got the following error:

Code:
Checks failed... [ret = 4]
Nothing was done.

Details:
Error: /dev/mtdblock0 not found

$ dmesg | grep -i spi
---
[   1.176820] spi-nor spi0.0: unrecognized JEDEC id bytes: ff ff ff ff ff ff
[   1.184548] spi-nor: probe of spi0.0 failed with error -2
---

I booted the Pinephone Pro to the Manjaro-Phosh installation I put on it and I used fdisk -l and ls /dev/ but I did not find the SPI Flash nor any mtd or mtdblock devices.
I have reinstalled Manjaro to the Pinephone Pro through booting on an SD card and through connecting my Pinephone Pro to my computer as an external drive using the Tow-Boot installer booted on an SD card.
I have tried to write the Tow-Boot.spi.bin binary to the SPI through putting my phone in MaskRom mode and using the rkdeveloptool through the command line on my linux laptop.
I have tried to zero everything out with rkdeveloptool by writing zeros.
I booted the factory android image with the hardware test app on an SD card and the SPI Flash failed its test.
I tried all of these at least twice each and they have all returned no errors, but I still get the same error from the Tow-Boot installer and I still cannot find the SPI Flash device or any mtd or mtdblock devices.

Is there any way to revive the SPI device? Would it require wiring to it directly since nothing has been able to read it?
Thank you in advance!

I should note, that my Pinephone Pro boots to the internal emmc and to SD cards without a problem, so fixing the SPI is not vital to using my pinephone pro, but I don't like to loose available hardware and it would be nice to install Tow-Boot.


  Big thanks for the documentation!

Hi,

I am a happy and daily Pinebook Pro user since may 2021. The last years, I broke the USB-C port, then the keyboard panel at the left hinge.
I decided to replace the motherboard and keyboard panel, ordered the pieces and received them3 days after.

Then I had some free hours yesterday to fix my loved laptop. And I was really pleased by the well written documentation. I followed the section describing the different steps with very clear illustrations.
And in some minutes, I have a almost new shiny laptop.

Everything was immediately working except wifi and bluetooth, because the chips changed (BCM43456 to BCm43455) the new chip is supported by official linux firnware and same for bluetooth.

Very happy user  Cool


  Pinecil low temp mods?
Posted by: davidcoley - 06-21-2026, 02:53 AM - Forum: General Discussion on Pinecil - No Replies

Hello,
I'm a complete beginner to this area, but I'm interested in using a Pinecil V2 with wax for jewellery modelling. Before I buy one, I'm wondering whether it's possible to modify it to operate at around 60°C or lower while still maintaining accurate temperature control.

Has anyone tried this, or does anyone have experience using a Pinecil for wax work? I'd be interested to hear your thoughts, recommendations, or any potential limitations before I make a purchase.

Maybe since I did https://wiki.pine64.org/wiki/PinePhone_P...der_to_SPI , replacing ppp/spinor-flash-initial-setup.sh , inside ./rk2aw/rk2aw-spi-flasher --erase-all --rk2aw rk2aw/debug.img.spi : debug by normal, I redid with debug as original but still that issue.

In theory, could i run some pbx server software on the pinephone, considering it already has sim card slot and modem, could be a low cost solution...
Motivation? Have your local simcard calls available worldwide over vpn...
