Identification

The board reads "Mixtile LOFT-Q"

The board comes with Android 4.4.2 (3.3.0 kernel) preloaded in the EMMC.

  • Model Number: Softwinner

Sunxi support

Current status

The Mixtile LOFT-Q is only partially supported, benefited from Humming bird.

Sunxi Kernel

Like all A31 based devices, there is no support in our sunxi kernel.

Sunxi U-Boot

Linux-sunxi's U-Boot currently lacks SPL support. This means that you have to chain load it from Allwinner's bootloader How?.

Mainline kernel

Mainline kernel support is included in 3.17. Currently only UARTs, USB, I2C, and GMAC are supported.

Use the sun6i-a31-hummingbird.dtb device-tree file for the mainline kernel.

Manual build

  • For building u-boot, use the "MANUFACTURER_DEVICE" target.
  • The .fex file can be found in sunxi-boards as hummingbird_a31.fex

Everything else is the same as the manual build howto.

Tips, Tricks, Caveats

FEL mode

The U-Boot button triggers FEL mode. See BROM for more information on the boot sequence.

Datasheet

Will soon be released.

Expansion Ports

The Mixtile LOFT-Q exposes 3 x 60 pins 0.5 mm pitch connectors with lots of expansion possibilities.
