The Cubieboard4 Board is a development board for the Allwinner A80 SoC.

Identification

The board has a Cubietech logo, the names "Cubietech", and "CC-A80", just above the WiFi antenna.

Sunxi support

Current status

Sunxi Kernel

Like all A80 based devices, there is no support in our sunxi kernel.

Sunxi U-Boot

Like all A80 based devices, there is no support in u-boot-sunxi.

Mainline kernel

Mainline kernel support is queued up for 4.2. Currently only MMC and UARTs are supported.

Use the sun9i-a80-cubieboard4.dtb device-tree file for the mainline kernel.

Mainline u-boot

Use the Cubieboard4_defconfig build target.

HW-Pack

BSP

Manual build

Follow SDK build howto to build u-boot and the kernel from the SDK.

Mainline kernel

Initial support for the A80 based on the Cubieboard 4 board is being worked on.

Use the sun9i-a80-cubieboard4.dtb device-tree file for the mainline kernel.

Tips, Tricks, Caveats

FEL mode

There is no FEL mode button on this board.

Instead you can enter fel mode from U-Boot. While U-Boot is starting, type CTRL+C to interrupt it. At the prompt type efex to enter fel mode.

If booting fails entirely then FEL mode can be entered by shorting pin 29-30 on the nand/emmc with a suitable metal object (tweezer or the like), by vendor official procedure.

Expansion Ports

The Cubieboard4 board exposes a 2 mm pitch connector for GPIO.

GPIO Connector

The pinout is printed on the board:
