The Banana Pi M2 Zero [1] is a board from Sinovoip, based on the
Allwinner H2+ SoC.

It is similar to the other Banana Pi M2* boards, from which this
configuration is inspired.

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+Buildroot environment for the Bananapi M2 Zero. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+Bananapi M2 Zero link:
+http://www.banana-pi.org/m2z.html
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+  $ make bananapi_m2_zero_defconfig
+  $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+  $ sync
+
+Insert the micro SDcard in your Bananapi M2 Zero and power it up. The console
+is on the Debug UART on the CON3 header, with serial settings 115200 8N1.
