Installation
Simply write the image to a sdcard and put it on the device, it should load u-boot and kernel automatically.
Notes
Like most devices with silead touch screen you may need to extract touch screen driver from android firmware. firmware for this tablet was gsl1680-b482-q8-a70.fw, which could be either taken from here or from android directly. while the screen resolution was 800 x 480, touch panel had 900 x 600.
Bluetooth
On devices that ship with realtek 8702as (or 8723bs), a firmware and a binary config file are required for bluetooth driver to work properly.
these are available under package firmware-realtek.
