Serial console

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 tablet side is:

  • Tip: RX
  • Ring: TX
  • Sleeve: GND

The serial connection is 3.3V

You can also buy the debug cable from PINE64 Store

Hardware switches

There's a 6 contact dipswitch on the back of the phone underneath the back cover. The 6 switches are for enableing/disableing hardware components. The switch has tiny numbers 1-6 beneath the contacts, moving the contact up sets that contact on.

# Off On
1 Modem disabled Modem enabled
2 Wifi/BT disabled Wifi/BT enabled
3 Microphone disabled Microphone enabled
4 Rear camera disabled Rear camera enabled
5 Front camera disabled Front camera enabled
6 Headphone UART mode Headphone audio mode

Cameras

The camera's 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, maybe Linux just deals with it if the device tree nodes for the second camera get added.

The camera hardware pipeline is controlled with /dev/media0 and media-ctl, the result is on /dev/video0

pine-dontbeevil:~# media-ctl --set-v4l2 '"ov5640 2-003c":0[fmt:UYVY8_2X8/1280x720]'
pine-dontbeevil:~# ffmpeg -s 1280x720 -f video4linux2 -i /dev/video0 -vframes 1 selfie.jpg

Camera Flash

The camera flash consist out of a SG Micro SGM3140 "500mA Buck/Boost Charge Pump LED Driver" and a EHP-C04 LED.

The driver supports Flash and Torch mode, the first being brighter but only for about 300ms, when it switches to Torch mode. Torch mode is lower brightness but can be turned on continuously.

# Turn on Flash, wait 0.3s, turn off
echo 1 > /sys/class/leds/sgm3140-flash/flash_strobe
sleep 0.3
echo 0 > /sys/class/leds/sgm3140-flash/flash_strobe
# Turn on Torch
echo 1 > /sys/class/leds/sgm3140-flash/brightness
# Turn off Torch
echo 0 > /sys/class/leds/sgm3140-flash/flash_strobe


WiFi

?

Bluetooth

There is a patch series on lkml. A v2 for this series is in progress.

Modem

Receiving text messages works. Calls should work too but weren't tested yet.

Sensors

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

dontbeevil:~# cat /sys/bus/iio/devices/iio\:device0/name
mpu6050
dontbeevil:~# cat /sys/bus/iio/devices/iio\:device0/in_accel_z_raw
-17594
dontbeevil:~# echo "Verified gravity still exists"

RGB Led

The RGB led works with the led driver, but due to hardware bugs there can be only one led active at the same time and the blue led doesn't work because some pins are reversed.

# Activate LED
echo 1 > /sys/class/leds/$COLOR/brightness
# Deactivate LED
echo 0 > /sys/class/leds/$COLOR/brightness

Audio

Speakers

Sound output should work after unmuting AIF1 Slot 0 digital

Mic

Doesn't work yet.

USB

Doesn't work for MartijnBraam, reported to work for other people.
