[[!meta title="NetBSD/evbarm on Allwinner Technology 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

- Download or build **armv7.img** 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/&lt;boardname&gt;/u-boot-sunxi-with-spl.bin of=/dev/rld0d bs=1k seek=8 conv=sync**
