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

Mainline U-Boot
Use the  build target.

Mainline kernel
Use the  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 used by the SATA bridge, the board has a SMSC USB3053 USB 2.0 HSIC hub chip, providing the 2 USB host ports on the board. This hub chip is controlled via I2C. Linux mainline has a proper driver ("usb3053") for it.

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.

= Adding a serial port =



There is a nice 0.1" connector behind the USB ports, just plug in your UART adapter.
