[[!meta title="NetBSD/evbarm on Allwinner Technology SoCs"]]
-NetBSD 7.0 has support for A20 and A31 SoCs. NetBSD -current adds support for A80 SoCs.
+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.

# Installation
-## A20 / A31 based boards
+- 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**
+
+# Tips and tricks
+
+## Video overscan compensation
+
+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:
-* Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/armv7.img.gz* from
-NetBSD 7.0
-* Download a U-Boot build for your board
- * Download the correct build from the linux-sunxi web site .
-* Decompress the image via [[!template id=man name="gunzip" section="1"]]:
-[[!template id=programlisting text="""
-# gunzip armv7.img.gz
-"""]]
-* Write the *u-boot-sunxi-with-spl.bin* loader to the empty space at the start of the base image:
-[[!template id=programlisting text="""
-# dd if=u-boot-sunxi-with-spl.bin of=armv7.img bs=1k seek=8 conv=notrunc
-"""]]
-* Write the image to an SD card (e.g.: if the SD card is recognised as *sd0* -
-please check the [[!template id=man name="dmesg" section="8"]] output to be
-sure!):
-[[!template id=programlisting text="""
-# dd if=armv7.img of=/dev/rsd0d bs=1m
-"""]]
-* Copy the kernel (*netbsd.ub*) for your board to the root of the MS-DOS
-partition on the SD card
-* Prepare a *boot.cmd* file for U-Boot boot loader containing the needed
-instructions regarding how to boot the kernel (basically the *bootargs* that are
-passed to the kernel and how to load the kernel from a device to the RAM and
-then boot it from the memory address):
-
-[[!template id=filecontent name="boot.cmd" text="""
-setenv kernel_addr 82000000
-setenv kernel netbsd.ub
-setenv bootargs "root=ld0a"
-
-fatload mmc 0:1 ${kernel_addr} ${kernel}
-bootm ${kernel_addr}
-"""]]
-* The *boot.cmd* text file should be converted in a script image - *boot.scr*
-for U-Boot via [[!template id=man name="mkubootimage" section="1"]]:
-[[!template id=programlisting text="""
-# mkubootimage -A arm -n armv7 -T script boot.cmd boot.scr
-"""]]
-* Copy the *boot.scr* to the MS-DOS partition of the SD card
-
-## A80 based boards
-
-* Cubieboard 4 U-Boot for SD card:
-[[!template id=programlisting text="""
-# dd if=u-boot-spl.bin of=/dev/sdd bs=1k seek=8
-# dd if=u-boot-sun9iw1p1.bin of=/dev/sdd bs=1k seek=19096
-"""]]
-* First partition needs to be at +20MB offset. Format it as MSDOS, copy 'netbsd.ub' to it as 'uImage'.
-
-# 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.
-
-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.
-
-# 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:
-
-[[!template id=filecontent name="uEnv.txt" 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
-"""]]
-
-Some pre-compiled .bin files can be found here:
-
-# Framebuffer console
-
-To use HDMI for the console device, add *console=fb* to bootargs in uEnv.txt.
-
-If the connected display does not let you disable overscan, you can add a margin to the framebuffer by with the *fb.margin* bootargs option. For example, to set a 25-pixel margin around the screen, add *fb.margin=25* to uEnv.txt
-
-# HDMI audio
-
-The default audio device is the analog audio codec. To change the default device, use the *audiocfg* command:
-
-[[!template id=programlisting text="""
-a31# audiocfg list
-0: [*] audio0 @ awinac0: Allwinner CODEC A31, 2 playback channels
-1: [ ] audio1 @ awinhdmiaudio0: Allwinner HDMI 1.4, 2 playback channels
-a31# audiocfg default 1
-setting default audio device to audio1
-a31# audiocfg list
-0: [ ] audio0 @ awinac0: Allwinner CODEC A31, 2 playback channels
-1: [*] audio1 @ awinhdmiaudio0: Allwinner HDMI 1.4, 2 playback channels
-"""]]
-
-# MAC address
-
-On boards where the ethernet MAC address cannot be determmined, a random MAC address will be generated every boot. You can override this behaviour by specifying a MAC address in *uEnv.txt*:
-[[!template id=filecontent name="uEnv.txt" text="""
-bootargs=root=ld0a awge0.mac-address=02:a0:3d:88:1a:1e
