Installation

Init pmbootstrap:

$ pmbootstrap init

note that this model is listed under Vendor surftab and not trekstor. To fix touchscreen drivers add g++,make as additional packages. Plug your micro sd card into your computer and take note of its file system position with:

$ dmesg|tail

usually a common position is /dev/mmcblk0. Then run:

$ pmbootstrap install --sdcard=/dev/mmcblk...

do not use --fda. This device does not support encryption.

Hardware

This is some information about the hardware that does not work out of the box.

Bluetooth

Possible solution: [1]

Battery

Works with the following modules enabled: CONFIG_BATTERY_MAX17042, CONFIG_EXTCON_AXP288, CONFIG_AXP288_CHARGER, CONFIG_AXP288_FUEL_GAUGE, CONFIG_AXP288_ADC

Sound

Works if configured with alsamixer: [2]

Camera

The back camera is a OmniVision OV2680. There seems to be some support in the kernel. [3]

Touchscreen

Touchscreen is semi-working. These are the steps to get it working properly:

$ git clone https://github.com/onitake/gslx680-acpi
$ cd gslx680-acpi
$ sudo make install
