Olimex A20-OLinuXino-Micro

A20-OLinuXino-Micro is fully OSHW A20 based development board from our friends at Olimex.

This board was originally designed with the pin-compatible A10 in mind. While this design never shipped, Olimex can produce A10 versions of this board if you so desire.

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

Sunxi/Legacy U-Boot

 * The .fex file can be found in sunxi-boards as a20-olinuxino_micro.fex
 * There are also several fex files dealing with the different LCDs in the same directory.

Mainline U-Boot

 * For building U-boot, use the A20-OLinuXino_MICRO_defconfig target.
 * There is another U-boot target for the eMMC version, A20-OLinuXino_MICRO-eMMC_defconfig.

Mainline kernel
Use the sun7i-a20-olinuxino-micro.dtb device-tree binary. See mainline kernel.
