<h3>Introduction</h3>
<p>This page contains information about the FreeBSD port to the
ARM architecture and hardware. Discussion of the ARM port takes
place on the
<a href="http://lists.freebsd.org/mailman/listinfo/freebsd-arm">freebsd-arm</a>
mailing list.</p>

<h3><a name="status">Status</a></h3>
<p>ARM is officially a
<a href="&base;/doc/en_US.ISO8859-1/articles/committers-guide/archs.html">
Tier 2</a> architecture, as the <a href="&base;">FreeBSD</a> project
does not provide official releases or pre-built packages for this
platform due to it primarily targeting the embedded arena. However,
FreeBSD/ARM is being actively developed and maintained, is well supported,
and provides an excellent framework for building ARM-based systems.</p>
<h3><a name="hw">FreeBSD/ARM Hardware Notes</a></h3>
<p>FreeBSD should work on the i80321 based Intel XScale®
devboards, which includes the IQ31244 and IQ80321 boards.
Support is still minimal, covering only the CPU, PCI-X bus,
em(4) Ethernet adapters, the UART and timer devices.</p>
<p>The i80219 XScale processor is supported, as is the EP80219
devboard.</p>
<p>The IXP425 is supported, as is the Avila GW2348-4 devboard.</p>
<p>The Atmel AT91RM9200 CPU/Microcontroller range is supported.
Support is provided for the Kwikbyte KB9202 devboard range, the
BWCT board and the Hot-e HL200 thin client device.</p>
<p>Minimal support for the StrongARM 1100 CPU is provided, but
only within the limits of what Simics emulate: CPU, UART and
clock. It is theoretically possible to boot on the Assabet board,
the one Simics emulates; no attempts, successful or unsuccessful,
have been reported.</p>
<p>Additionally, support for the Technologic Systems TS-7200 devboard
is in the works, as is support for the Atmel AT91SAM926x CPU and
the Marvell Orion ARM SoC, the Samsung S3C2XX0 range, and Cirrus
Logic EP93XX CPUs.</p>
<h3><a name="todo">What Needs To Be Done</a></h3>
<ul>
<li>SATA support needs to be added.</li>
<li>Other devices, such as watchdog, i2c and bus should be merged
from NetBSD.</li>
</ul>

<h3><a name="miniinst">Mini-Install guide</a></h3>
<p>&a.cognet; (cognet@FreeBSD.org) has written a mini-install guide for the
current FreeBSD source. It is
<a href="http://people.freebsd.org/~cognet/arm.html">available here</a>.</p>

<h3>What musicians say about FreeBSD/ARM</h3>
<p>With FreeBSD/ARM, you can enjoy the silence from running your
(embedded) computer. There's even a song of that name, "Enjoy
The Silence", by Depeche Mode:</p>
<pre>All I ever wanted
All I ever needed
Is here in my ARMs
Words are very unnecessary
They can only do harm</pre>
