+A33-OLinuXino
+
+Intro
+=====
+
+This board is based on Allwinner A33 SoC.
+
+Home Page: https://www.olimex.com/Products/OLinuXino/A33/A33-OLinuXino/open-source-hardware
+Wiki: 	   https://wiki.amarulasolutions.com/bsp/sunxi/a33/Olimex-A33-Olinuxino.html
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make olimex_a33_olinuxino_defconfig
+
+Build everything by running:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+output/images/
+├── boot.scr
+├── rootfs.ext2
+├── rootfs.ext4 -> rootfs.ext2
+├── rootfs.tar
+├── sdcard.img
+├── sun8i-a33-olinuxino.dtb
+├── u-boot.bin
+├── u-boot-sunxi-with-spl.bin
+└── zImage
+
+
+How to write the SD card
+========================
+
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to a uSD
+card:
+
+    # dd if=output/images/sdcard.img of=/dev/sdX
+
+Where 'sdX' is the device node of the uSD.
+
+Eject the SD card, insert it in the A33-OLinuXino board, and power it up.
