Serial console

The PineTab has a serial port in the headphone connector, it's activated by a switch behind the SD card cover. If the switch is pointed toward the SD card the headphone connector is in audio mode, if it's pointed the other way 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.

Touchscreen

The touchscreen on the PineTab is controlled by goodix module on i2c-0, at address 0x5d.

Cameras

Both front and back camera shares the same csi-0 bus. Currently only the back camera (OV5640) has mainline support.

It's not clear what would it reacts to both front and back camera. More information needed on this.

Since Cerdus is at /dev/video0 , the CSI is at /dev/video1 and can be controlled with /dev/media1 using media-ctl

pine-pinetab:~# media-ctl --set-v4l2 '"ov5640 2-003c":0[fmt:UYVY8_2X8/1280x720]' -d /dev/media1 pine-pinetab:~# ffmpeg -s 1280x720 -f video4linux2 -i /dev/video1 -vframes 1 selfie.jpg

Wi-Fi

Wi-Fi works using the RTL8723CS driver from Icenowy, loads and connect to a Wi-Fi perfectly fine. However power saving capabilities aren't working, so the PineTab battery will drain more quicker.

Bluetooth

Bluetooth also works on this device after installing firmware-rtl8723bt , there is a patch series on LKML.

Accelerometer

The accelerometer driver is for BMA250 on mainline, and works just fine. The accelerometer value could be get here:

pine-pinetab:~$ cat /sys/bus/iio/devices/iio \: device1/name BMA222E pine-pinetab:~$ cat /sys/bus/iio/devices/iio \: device1/in_accel_x_raw -1 pine-pinetab:~$ cat /sys/bus/iio/devices/iio \: device1/in_accel_y_raw 28 pine-pinetab:~$ cat /sys/bus/iio/devices/iio \: device1/in_accel_z_raw -12

Audio

Speakers

Sound output should work after unmuting AIF1 Slot 0 digital and DAC . However Danct12's unit had it's speakers broken so this hasn't tested on him, but confirmed working on others.

The Speaker output is named "Line Out"

Headphone Jack

Thankfully our device still has the headphone jack, so you could still listen to "The Beatles", right?

Well, sure. Headphones should work after unmuting Headphone and AIF1 Slot 0 digital .

Microphone

Microphone can be enabled by toggle capture and unmute "AIF1 Data Digital Audio", "Mic1", "Mic2".
