Cubietech Cubieboard4

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 =

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.

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:

= Serial console port =



The UART header is next to the VGA port. Pinout is printed in small font next to the header.

= Pictures =

= Also known as = Cubietech also uses the name "CC-A80", both printed on the board and on their websites, for this board.
