Installation
The PineTab 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).

From pre-built image (easy method)
Official images of postmarketOS are built at least every week. There are several images to choose from, so read the following to help you navigate through the downloads page.

Download the right image

 * Choose an image for your device from the download page.
 * User interface
 * Phosh: Purism's GTK based phone interface (This is what we shipped with the postmarketOS community edition.)
 * Plasma Mobile: KDE's Plasma based phone interface.
 * Pick the latest image by its date
 * Choose the regular image, or the installer image
 * Graphical Installer:
 * Ends in
 * Recommended for a proper installation.
 * Allows to install postmarketOS to the microSD card or to internal memory (eMMC)
 * Encrypting your installation is possible
 * Passwords for user and SSH are set during installation (and SSH can be disabled)
 * Regular image:
 * Ends in
 * Like a live CD, flash it to your microSD card to try postmarketOS out.
 * The login is  with password

Flash to microSD card
After downloading the image, figure out the name of the microSD card. Run  once, then insert the microSD card and run   again. The microSD card is the newly appeared device, and you can take a look at the reported size to be extra sure. You should really double check that you pick the right device, otherwise you can overwrite the wrong disk by accident. Flash the image as shown below, replace  with the device name of your microSD card.

When you are done, insert the microSD into your PineTab and boot it up.

With pmbootstrap (advanced)

 * Install pmbootstrap
 * Run . As of writing, the PineTab is only available in the   channel, so select that when asked.
 * Insert SD card into your PC
 * Use  to figure out the path to the SD card device (e.g.  )
 * Run . Add   if you want to encrypt your installation. Add   if you want to create on-device installer image.

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  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, the CSI is at   and can be controlled with   using



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, 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:

Speakers
Sound output should work after unmuting  and. 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  and.

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

The microphone can be found here:
