Subject: [Buildroot] [PATCH] orangepi: add basic support for orangepi-zero board
Date: Sat, 20 May 2017 16:31:53 +0300	[thread overview]
Message-ID: <20170520133153.2673-1-geomatsi@gmail.com> (raw)

Board support package includes the following components:

- mainline kernel v4.11
- mainline u-boot v2017.03
- extra kernel config options and dts patches to enable SPI NOR and spidev

More details about this board are available here:
- http://linux-sunxi.org/Orange_Pi_Zero

Note that at the moment networking is not supported right out of the box.
Ethernet submission to mainline kernel is a work in progress, see the
latest dwmac-sun8i branches at https://github.com/montjoie/linux

On-board SDIO WiFi chip XR819 is supported by off-the-tree wireless
driver available at https://github.com/fifteenhex/xradio

+OrangePi Zero
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the OrangePi Zero. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make orangepi_zero_defconfig
+
+Compile everything and build the SD card image:
+
+    $ make
+
+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
