OpenBSD/armv7

OpenBSD armv7

OpenBSD/armv7 is a port of OpenBSD to various ARMv7 based systems.

A mailing list for ARM-based ports is available at arm@openbsd.org. To join the OpenBSD/arm mailing list, send a message body of "subscribe arm" to majordomo@openbsd.org. Please be sure to check our mailing list policy before subscribing.

Current status

The current target platforms are Allwinner A10/A20/A33/A80, H2+/H3, R16/R40, V40 (sunxi), Freescale i.MX6/7 (imx) and TI OMAP4/AM3 (am335x/panda). We try to support most of the boards based on those SoCs. A list of supported boards is in the supported hardware section.

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 am335x, imx, panda and Allwinner A10/A20/H2+/H3.

Supported hardware

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 imx, all devices based on Allwinner SoCs are referred to as sunxi. The boards with an TI OMAP4/AM3 SoC are subdivided into am335x (for BeagleBone) and panda (for PandaBoard).

No real time clock: Many of the armv7 devices do not have a battery-backed real time clock, but ntpd(8) should be able to compensate.

Getting and installing

The latest supported OpenBSD/armv7 release is OpenBSD 7.5. Here are the OpenBSD/armv7 installation instructions.

Snapshots are made available from time to time, in this location as well as on a few mirrors. Here are the OpenBSD/armv7 snapshot installation instructions as well.
