The board helpfully states "CUBIETRUCK PLUS".

According to Cubieboard's resources repository, there are 2 versions: v1.0 and v1.1. Cubietech states that all retail pieces are v1.1.

Sunxi support

The board is supported by both mainline U-Boot and kernels.

Current status

Manual build

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

U-Boot

Mainline U-Boot

Use the Cubietruck_plus_defconfig build target.

Linux Kernel

Mainline kernel

Use the sun8i-a83t-cubietruck-plus.dtb device-tree binary.

Tips, Tricks, Caveats

FEL mode

The UBOOT button forces boot from mmc0, and drops to FEL mode if no boot signature is found.

Display Port

This board has a DP output, supported with a Toshiba TC358777XBG MIPI DSI - DP bridge. With Cubietech's images, one must switch out the FEX files to use DP instead of HDMI. This bridge chip is controlled via I2C.

SATA

The SATA port is not native SATA. It is supported by a GL830 USB 2.0 to SATA bridge. This chip is connected directly to the SoC's USB host.

USB 2.0 Hosts

Since the only USB 2.0 host is connected to the SATA bridge chip, the board has a SMSC USB3053 USB 2.0 HSIC hub chip, providing 2x Type-A USB host ports on the board.
This USB3053 chip is controlled via I2C. Linux mainline kernel provides a driver ("usb3053") for it.
1x OTG MicroUSB

Acrylic Case

The board comes with an plastic case, which is just 3 pieces of acrylic screwed together with the board using spacers. The screw holes on these are not very accurate, so one might not be able to do a complete assembly.

Possible software issues

If you're using Cubietech's OS image and processes get sigkilled when run under UID != 0 check the contents of /proc/sys/vm/mmap_min_addr. If it's 65536 then try to decrease the value to 32678 or even 4096 and see whether that helps.

CPU Heating issues

The A83/H8 absolutely needs a heatsink, active cooling is heavily recommended, otherwise the CPU will lower max frequency or even stop using cores.

Adding a serial port

Locating the UART

DEVICE UART pads

There is a nice 0.1" connector behind the USB ports Just attach some leads according to our UART howto.
