PINE64 PinePhone (pine64-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 PinePhone will boot from a bootable microSD card if it is plugged, and fall back to booting from internal eMMC. You can install postmarketOS on either of them (or even on both).
$ pmbootstrap init # vendor: pine64, device: pinephone $ pmbootstrap install --sdcard=/dev/mmcblk... # add --fde for full disk encryption
After that, unplug the microSD card from your PC, put it in your PinePhone and postmarketOS should boot up. (Note that the microSD fits in the SIM slot, but that does of course not work.)
For a quick demo, you may use a test image from images.postmarketos.org instead of building your own image with pmbootstrap.
$ wget https://images.postmarketos.org/pinephone/pine64-pinephone-20200724-phosh-v20.05-installer.img.xz $ xzcat pine64-pinephone-20200724-phosh-v20.05-installer.img.xz | sudo dd of=/dev/mmcblk... status=progress
Create a new image with pmbootstrap (recommended, details) or download a pre-built image (see above).
$ pmbootstrap init # vendor: pine64, device: pinephone, select "stable" channel $ pmbootstrap install # add --fde for full disk encryption $ pmbootstrap export $ realpath /tmp/postmarketOS-export/pine64-pinephone.img /home/user/.local/var/pmbootstrap/chroot_native/home/pmos/rootfs/pine64-pinephone.img
$ wget https://github.com/dreemurrs-embedded/Jumpdrive/releases/download/0.6/pine64-pinephone.img.xz $ sha512sum pine64-pinephone.img.xz 79019771a7ade68a6e97e030e835b6357a3f71bae7cb3297e8772f8e069bd26033809f43ead7a0dfdf82d0ea537a7e3530c6d8935a9af040c6da211dc2ebdbb3 pine64-pinephone.img.xz $ xzcat pine64-pinephone.img.xz | sudo dd of=/dev/mmcblk... status=progress
Insert the microSD card into your PinePhone and boot it up. It should display the Jumpdrive splash screen.
Connect your PinePhone via USB to your PC and use
lsblk to figure out the correct target partition. You should see two new devices in
lsblk. One device has just one small ~40 MiB partition, this is the microSD card with JumpDrive. The other device is the eMMC. You should flash to the device itself (typically of the form /dev/sdx) and not a partition (/dev/sdxn where n is a number).
$ lsblk (now plug the USB cable) $ lsblk
Prepare the final
dd command to flash postmarketOS to the eMMC and triple-check that you have put the right device as
of argument. Then run it.
$ sudo dd if=~/.local/var/pmbootstrap/chroot_native/home/pmos/rootfs/pine64-pinephone.img of=/dev/sd... status=progress
As of writing, Jumpdrive doesn't have a shutdown procedure (#2). Maybe leave it on for a few more minutes after the
dd command is done to make sure that the data isn't still in some cache, but really written to the eMMC (the author had data corruption once, which might be related to turning it off too quickly after flashing). Then press the power button for five seconds to power it off. Remove the microSD card, turn it on again. The PinePhone should boot into postmarketOS.
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:
|5V / VBUS||VBAT||GND|
The VBUS pin is powered by USB and is 5V. The second power pin is VBAT, which connects to the battery voltage. The I2C and interrupt lines have pull-ups on the phone side. The I2C lines are pulled up to 3V3 by the phone.

The cameras both share the csi-0 bus. Currently only the rear camera (OV5640) has mainline linux support, a driver for the front camera (GC2145) is being developed in the kernel fork for the phone development.
Both camera's share the same bus for the video stream, due to this it's impossible to use both cameras at the same time, but you can switch between the cameras by keeping one of them in reset and then restarting the whole pipeline.
Switching to the rear camera $ sudo media-ctl -d /dev/media1 --links "gc2145 3-003c":0->"sun6i-csi":0 $ sudo media-ctl -d /dev/media1 --links "ov5640 3-004c":0->"sun6i-csi":0 Switching to the front camera $ sudo media-ctl -d /dev/media1 --links "ov5640 3-004c":0->"sun6i-csi":0 $ sudo media-ctl -d /dev/media1 --links "gc2145 3-003c":0->"sun6i-csi":0
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
Or use only modemmanager which integrates better with phosh.
pinephone:~# sudo mmcli -m 0 --create-bearer='apn=APN.NAME,user=USERNAME,password=PASSWORD,allowed-auth=chap,allow-roaming=no' pinephone:~# sudo nmcli c add type gsm ifname cdc-wdm0 con-name OPERATOR-NAME apn APN.NAME user USERNAME password PASSWORD # Check your connection pinephone:~# nmcli c # check status of the connection named OPERATOR-NAME as above pinephone:~# nmcli d # check status of cdc-wdm0
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
The EG25 modem in the PinePhone comes preloaded with VoLTE profiles for a few providers. The modem can handle VoLTE fully internally so nothing complicated is required on the postmarketOS side. PostmarketOS tries to set the VoLTE profile automatically. If that fails it can also be set manually:
# List of embedded VoLTE profiles $ echo 'AT+QMBNCFG="list"' | atinout - /dev/EG25.AT - +QMBNCFG: "List",0,1,1,"ROW_Generic_3GPP",0x0501081F,201901141 +QMBNCFG: "List",1,0,0,"VoLTE-ATT",0x0501033C,201909271 +QMBNCFG: "List",2,0,0,"hVoLTE-Verizon",0x05010141,201911251 +QMBNCFG: "List",3,0,0,"Sprint-VoLTE",0x05010205,201908141 +QMBNCFG: "List",4,0,0,"Commercial-TMO_VoLTE",0x05010505,201811231 +QMBNCFG: "List",5,0,0,"Telus-Commercial_VoLTE",0x05800C43,201912031 +QMBNCFG: "List",6,0,0,"Commercial-SBM",0x05011C18,201904021 +QMBNCFG: "List",7,0,0,"Commercial-DT",0x05011F1C,201905311 +QMBNCFG: "List",8,0,0,"Reliance_OpnMkt",0x05011B38,201910161 +QMBNCFG: "List",9,0,0,"TF_Germany_VoLTE",0x05010C1B,201909201 +QMBNCFG: "List",10,0,0,"TF_Spain_VoLTE",0x05010CFA,201909261 +QMBNCFG: "List",11,0,0,"Volte_OpenMkt-Commercial-CMCC",0x05012071,201904281 +QMBNCFG: "List",12,0,0,"OpenMkt-Commercial-CT",0x05011322,201911081 +QMBNCFG: "List",13,0,0,"OpenMkt-Commercial-CU",0x05011505,201807052 OK # Select the profile most applicable to your provider, or use the Generic one if nothing matches $ echo 'AT+QMBNCFG="select","ROW_Generic_3GPP"' | atinout - /dev/EG25.AT - OK # Enable calling over ip (VoLTE) $ echo 'AT+QCFG="ims",1' | atinout - /dev/EG25.AT - OK # Reboot the modem to apply the settings $ echo 'AT+CFUN=1,1' | atinout - /dev/EG25.AT -
After this process VoLTE should be used when available. To check the status while in a call you can run the CLCC command:
$ echo 'AT+CLCC' | atinout - /dev/EG25.AT - +CLCC: 1,1,0,1,0,"",128 +CLCC: 2,1,0,1,0,"",128 OK
The "1" in the 4th column on the second CLCC row means it's currently calling with VoLTE, when it's "0" it's calling over the legacy phone network.
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.
