-## A10 / A20 based boards
+NetBSD supports many boards based on Allwinner SoCs. Starting with NetBSD 8.0, FDT is used to configure devices. As a result, a large number of boards and configurations can be supported with a single kernel.
-* Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beaglebone.img*
-* Download a U-Boot build for your board from the linux-sunxi web site
-* Write the *u-boot-sunxi-with-spl.bin* loader to the base image:
-[[!template id=programlisting text="""
-# dd if=u-boot-sunxi-with-spl.bin of=beaglebone.img bs=1k seek=8 conv=notrunc
-"""]]
-* Write the image to an SD card.
-* Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition.
-* Create or edit uEnv.txt on the MS-DOS partition:
-[[!template id=programlisting text="""
-bootargs=root=ld0a
-uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000

-## A31 based boards

-TBD.
-
-# Big (endian) fun
-
-You can run this boards with a little endian (this is the default and implied by above install instructions)
-or with a big endian kernel and userland. However, kernel and userland endianness needs to match.
+[[!toc levels=2]]
-To build a big endian release (or sets) use
-[[!template id=programlisting text="""
-./build.sh -m evbearmv7hf-eb
-"""]]
-where -eb means endianness big, hf is hardware floating point support, and earm is the modern "extended" ABI for ARM CPUs, and finally v7 is version 7 of the supported instruction set.
+# Supported SoCs
-# FEX scripts
+
-Board configuration scripts can be found here: . You can compile them with the "fex2bin" tool found here: .
-To use, copy the compiled FEX to your MS-DOS partition, load it with U-Boot, and then tell the kernel where to find it with the "sysconfig=" boot option. For example, uEnv.txt on a Cubieboard2 might look like this:
+# Supported hardware
-[[!template id=programlisting text="""
-bootargs=root=ld0a sysconfig=0x43000000
-uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 43000000 cubieboard2.bin; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000

+Please refer to the [SUNXI kernel config](https://nxr.netbsd.org/xref/src/sys/arch/evbarm/conf/SUNXI) for the most up-to-date list of supported hardware.

-# Framebuffer console
+# Installation
-To use HDMI for the console device, add *console=fb* to bootargs in uEnv.txt.
+- Download or build **armv7.img** (32-bit) or **arm64.img** (64-bit) from NetBSD -current
+- Write the image to disk: **dd if=armv7.img of=/dev/rld0d bs=1m conv=sync**
+- Install a board-specific U-Boot (2017.07 or later) from pkgsrc to the SD card: **dd if=/usr/pkg/share/u-boot/<boardname>/u-boot-sunxi-with-spl.bin of=/dev/rld0d bs=1k seek=8 conv=sync**

+## Video overscan compensation
-There doesn't appear to be a meaningful way to generate a MAC address on these boards. U-Boot from the A31 SDK and from the u-boot-sunxi tree both lack GMAC support, and the Security ID registers (at 0x01c23800) appear to be empty.
+On some television models, the borders of the screen may be cut off. If your television doesn't have an option to disable overscan, you can enable overscan compensation by entering the following commands at the U-Boot prompt:
-To overcome this, you can specify your own MAC address in *uEnv.txt*:
-[[!template id=programlisting text="""
-bootargs=root=ld0a awge0.mac-address=02:a0:3d:88:1a:1e
