Interra-3 is an A20 based Smart Home automation board. It doesn't include any NAND, but instead has an eMMC.
Current PCB version is 3.0, under mass production..
Board is running sunxi uboot and sunxi kernel 3.4.79, with debian wheezy rootfs.
This is a proprietary product, therefore its images can not be published here :(
Does not exist. The board runs Android 4.2.2 and sunxi kernel. A working linux system can be built easily similar to any other A20 based device.
Does not exists.
- For building u-boot, use the "Interra-3" target.
- The .fex file can be found in sunxi-boards as interra-3.fex
Everything else is the same as the manual build howto.
