PINE64 PinePhone (pine64-pinephone)(Redirected from PINE64 PinePhone (pine-pinephone))
The PinePhone is a smartphone by PINE64. The postmarketOS vendor and device names are "pine64" and "pinephone" respectively. The back panel can be lifted off by pulling at the notch on the bottom-right corner of the phone. This exposes the battery, microSD and SIM slots, and dipswitches. It comes with a 3000mAh battery and uses the same form-factor as the Samsung Galaxy J7 (2015) for replacement.
The recommended installation procedure is installing to a microSD card by following the Installation Guide and to pass "--sdcard=/dev/(...)" to "pmbootstrap install".
postmarketOS can be installed onto the eMMC by flashing Jumpdrive onto a microSD, booting it with the USB connected to the PC and following the microSD install instructions above or by booting a Linux distribution on the phone first and doing the installation process via pmbootstrap on the phone directly:
- Install pmbootstrap and its dependencies on the phone on any Linux distribution booted via the microSD card
- Follow the Installation Guide until "Installation and flashing"
- Run "pmbootstrap install --sdcard=/dev/mmcblk2"
If this throws an error mentioning "/dev/installp2" when trying to install from postmarketOS on the microSD card over an existing installation of postmarketOS on the eMMC (including the factory test image), the partitions of the existing installation on the eMMC need to be deleted and the phone needs to be rebooted once after doing so due to a bug, see here
postmarketOS can also be installed using premade images from here. Some of these images are purely for demoing specific things and aren't usable for general use and will never be. These images can be installed by using dd, or your favorite image writer.
Installing postmarketOS on the eMMC directly from a computer via FEL is also supported. This requires the user to enable FEL mode, the boot-tools to mount the eMMC as mass storage are currently however not compatible.
The PinePhone has a serial port in the headphone connector, it's activated by the 6th contact on the dipswitch. If the switch is on then the headphone connector is in audio mode, if it's off then it's in UART mode.
The uart is 115200n8
The pinout for the serial connector on the headphone jack is:
- Tip: RX
- Ring: TX
- Sleeve: GND
The serial connection is 3.3V
There's a 6 contact dipswitch on the back of the phone underneath the back cover. The 6 switches are for enabling/disabling hardware components. The switch has tiny numbers 1-6 beneath the contacts, moving the contact up sets that contact on.

There is a 2x3 grid of pogo pins on the back of the PinePhone for connecting a back cover with extra hardware like an extended battery case or a keyboard case. The pinout for this connector:
the USB5v line is meant to charge the phone and the 3v3 is to power peripherals to the phone. The I2C and interrupt lines have pull-ups on the phone side.

The cameras both share the csi-0 bus. Currently only the rear camera (OV5640) has mainline linux support.
It's also not clear how the camera switching would work on the software side, the current issue is that the sunxi csi driver doesn't support multiple camera endpoints.
The camera hardware pipeline is controlled with
media-ctl, the result is on
pinephone:~# media-ctl -d /dev/media1 --set-v4l2 '"ov5640 3-004c":0[fmt:UYVY8_2X8/1280x720]' pinephone:~# ffmpeg -s 1280x720 -f video4linux2 -i /dev/video1 -vframes 1 selfie.jpg
Please note, that the driver for the sgm3140 is not yet included in the main kernel source and as such is not available for use yet without compiling the module yourself.
The camera flash consist out of a SG Micro SGM3140 "500mA Buck/Boost Charge Pump LED Driver" and a EHP-C04 LED. It supports Flash and Torch mode, the first being brighter but only for 200-300ms, when it switches to Torch mode automatically. Torch mode is lower brightness but can be turned on continuously.
Controlling the flash from user space is possible via sysfs and via v4l2:
# Torch on $ echo 1 > /sys/class/leds/white\:flash/brightness # Torch off $ echo 0 > /sys/class/leds/white\:flash/brightness # Activate flash $ echo 1 > /sys/class/leds/white\:flash/flash_strobe
# Torch on $ v4l2-ctl -d /dev/video1 -c led_mode=2 # Torch off $ v4l2-ctl -d /dev/video1 -c led_mode=0 # Activate flash $ v4l2-ctl -d /dev/video1 -c led_mode=1 $ v4l2-ctl -d /dev/video1 -c strobe=1
The wifi uses the rtl8723cs driver and is functional. There is still an issue with the driver not reloading correctly when the SoC is put into suspend mode, this can be worked around by reloading the kernel module:
pinephone:~# sudo rmmod 8723cs pinephone:~# sudo modprobe 8723cs
Main article: Bluetooth.
The bluetooth connection is handled by the wifi chipset. It is functional but there is no integration in Plasma Mobile yet. To pair a bluetooth device start the bluetooth service and use bluetoothctl to connect.
pinephone:~# sudo service bluetooth start pinephone:~# bluetoothctl # scan on [NEW] 00:11:22:33:44:55 # pair 00:11:22:33:44:55
To use bluetooth headphones with pulseaudio, the package
pulseaudio-bluez is required.
Receiving and sending text messages works, The calls work but there are some issues left with the audio routing. Mobile data is functional. For information on audio routing and setting up the modem in phosh, see the specific article.
To bring up mobile data run the following commands (for plasma mobile):
pinephone:~# sudo apk add ofonoctl pinephone:~# ofonoctl wan --connect --append-dns
In order to connect to the serial console of the modem, you need a terminal application. One option is to use
# apk add minicom
Connect to the console by issuing:
# minicom -D /dev/ttyUSB2
AT returns OK:
ATI returns some version information from the modem:
ATI Quectel EG25 Revision: EG25GGBR07A07M2G OK
AT+QDAI (Digital Audio Interface Configure) is used to configure the digital audio interface.
AT+QDAI? returns the current configuration:
AT+QDAI? +QDAI: 3,0,0,4,0,0,1,1 OK
All sensors work and are accessible as Industrial I/O (iio) devices in Linux. To query the data you can cat the files in `/sys/bus/iio/` to make the kernel module query the sensors
pinephone:~# cat /sys/bus/iio/devices/iio\:device0/name mpu6050 pinephone:~# cat /sys/bus/iio/devices/iio\:device0/in_accel_z_raw -17594 pinephone:~# echo "Verified gravity still exists"
# Activate LED echo 1 > /sys/class/leds/$COLOR/brightness # Deactivate LED echo 0 > /sys/class/leds/$COLOR/brightness
You may turn on and off the blue led by issuing:
# echo 1 > /sys/devices/platform/leds/leds/pinephone\:blue\:user/brightness # echo 0 > /sys/devices/platform/leds/leds/pinephone\:blue\:user/brightness
Make sure you run these commands as root (
sudo echo 1 > /sys/devices/platform/leds/leds/pinephone\:blue\:user/brightness, won't work.
Sound output should work after unmuting
AIF1 Slot 0 digital
Start by making sure alsa-utils are installed:
$ sudo apk add alsa-utils
You may use amixer, or alsamixer to unmute the required channels, and to control the volume:
$ amixer scontents $ amixer sset Master unmute
Alsamixer (use terminal keyboard input to use up/down/left/right keys, to set volume and select devices):
$ alsamixer -V all
Test the sound output by issuing:
$ speaker-test -c3
Failed to create boot/xxx: No space left on device
A bug has been observed where too many initramfs's are created. To fix, run the following commands to delete and regenerate all initramfs's
postmarketos:~# sudo rm /boot/initramfs* postmarketos:~# sudo apk fix linux-postmarketos-allwinner
Qt Based Browsers Not Loading Web Pages
Webkit sandbox is broken in the current build. In order to be able to use Qt based browsers it is necessary to create the file "/etc/profile.d/sandboxhack.sh" with the following contents:
#!/bin/sh export QTWEBENGINE_DISABLE_SANDBOX=1
This sets an environment variable that kills the webkit sandbox because that's broken in the current build. This should be fixed already for the chromium musl build but not yet for all qtwebkit based browsers. This is being worked on here and here.
