This section explains how to most easily identify your device. For a development board, explain the name(s) printed on the board. For an android device, find out the strings as reported under settings.

On the back of the device, the following is printed:

FUKUDA
FCT94AW8

The PCB has the following silkscreened on it:

INET-D98C-REV01

In android, under Settings->About Tablet, you will find:

Model Number: FCT94AW8
Build Number: A33_U98C_U902HC.20150209

Images

Optional. Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be removed.

HW-Pack

Optional. Add MANUFACTURER DEVICE sunxi HW-pack specifics here. When empty, this section can be removed.

BSP

Optional. Add MANUFACTURER DEVICE sunxi BSP specifics here. When empty, this section can be removed.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Sunxi/Legacy U-Boot

Use the MANUFACTURER_DEVICE build target.

Mainline U-Boot

Use the MANUFACTURER_DEVICE build target.

Linux Kernel

Sunxi/Legacy Kernel

Use the MANUFACTURER_DEVICE.fex file.

Mainline kernel

Use the FAMILY-CHIP-DEVICE.dtb device-tree binary.

Tips, Tricks, Caveats

At the moment, already tried this instruction on building the 3.4 kernel at this link.

Adding a serial port (voids warranty)

DEVICE UART pads

The serial port pads can be found near the touchscreen flex cable header and the uSD card slot. Make sure to refer to our UART howto.

Device disassembly

The back cover can be easily popped off. Start prying from top to bottom side(side with power button) Plastic tool howto.

Locating the UART

The serial port pads can be found near the touchscreen flex cable header and the uSD card slot. Make sure to refer to our UART howto.
