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.
The current target platforms are i.MX6 and OMAP3/4. We try to support most of the boards based on those SoCs. A list of supported boards is in the section Supported hardware. There are still a fair number of things to do on each of these boards. The platform is now self hosting, however there is no SMP support. Networking is working on i.MX6, the PandaBoard and the BeagleBone.
Snapshots are made available regularly, in this location as well as in a few mirrors.
Here are the OpenBSD/armv7 snapshot installation instructions as well.
