<p>
OpenBSD/armv7 is a port of OpenBSD to various ARMv7 based systems.
<p>
A mailing list for ARM-based ports is available at
<a href="mailto:arm@openbsd.org">arm@openbsd.org</a>.
To join the OpenBSD/arm mailing list, send a message body of
<b>"subscribe arm"</b> to
<a href="mailto:majordomo@openbsd.org">majordomo@openbsd.org</a>.
Please be sure to check our <a href="mail.html">mailing list policy</a> before

<h3 id="status"><strong>Current status</strong></h3>
<p>
The current target platforms are Allwinner A10/A20/A33/A80, H2+/H3,
R16/R40, V40 (<code>sunxi</code>), Freescale i.MX6/7 (<code>imx</code>) and TI
OMAP4/AM3 (<code>am335x</code>/<code>panda</code>). We try to
support most of the boards based on those SoCs. A list of supported
boards is in the <a href="#hardware">supported hardware</a> section.
<p>
There are still a fair number of things to do on each of these boards,
however OpenBSD is generally considered to be usable on them. The
platform is now self hosting, however there is no SMP support.
Networking is working on <code>am335x</code>, <code>imx</code>, <code>panda</code>
and Allwinner A10/A20/H2+/H3.
<h3 id="hardware"><strong>Supported hardware</strong></h3>
A note on the platforms and the associated boards: OpenBSD/armv7
bundles various platforms sharing the ARM v7 architecture. Due to the
fact that there are many System on a Chips (SoC) around, OpenBSD/armv7
differentiates between various SoCs and may have a different level of
support between them. All devices based on the Freescale i.MX6 and
i.MX7 are referred to as <code>imx</code>, all devices based on Allwinner
SoCs are referred to as <code>sunxi</code>. The boards with an TI OMAP4/AM3
SoC are subdivided into <code>am335x</code> (for BeagleBone) and
<code>panda</code> (for PandaBoard).
