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:
