= Sunxi support =

Current status
FEX file for the sunxi-3.4 kernel has been submitted to the mailing list. A patch for the legacy u-boot-sunxi bootloader has been submitted to the mailing list too.

The mainline kernel support is blocked on the missing USB OTG driver, which means no easy connectivity with the outside world. Unless we manage to alternatively take WLAN into use, which also may require some investigation.

The mainline u-boot support is blocked on the missing knowledge about the future DTB file name for this device.

Manual build

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

Everything else is the same as the manual build howto.
