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.
The board is supported by both mainline U-Boot and kernels.
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Use the Cubietruck_plus_defconfig build target.
Use the sun8i-a83t-cubietruck-plus.dtb device-tree binary.
Tips, Tricks, Caveats
The UBOOT button forces boot from mmc0, and drops to FEL mode if no boot signature is found.
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.
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
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
There is a nice 0.1" connector behind the USB ports Just attach some leads according to our UART howto.
