OpenBSD/landisk runs on machines related to the
IO-DATA USL-5P, using a
Hitachi/Renesas
SH-4 CPU.
This rather small unit (25cm x 10cm x 2cm) is sold only in Japan.
This platform comes in a variety of models:
The current port maintainers are Miod Vallat (miod@openbsd.org) and Michael Shalayeff (mickey@openbsd.org).
OpenBSD/landisk is the 1st OpenBSD port to a Hitachi/Renesas SH-4 based machine. It is hoped that other SH-4 based machines will show up which are interesting enough for our user and development community, but the SH-4 processor is normally used only in true embedded products.
Development is currently pretty active, and maybe soon it will work!
Snapshots are made available from time to time, in this location as well as in a few mirrors. Here are the OpenBSD/landisk snapshot installation instructions as well.
The cable converts from a DB9 connector to a 5-pin header (3.3V Rx Tx GND NC). All the boards have a 5-pin connector (called CN7) which the cable can plug into; except for the USL-5P which has a 4-pin header and also requires that the Rx and Tx pins be swapped. The IO-DATA cable has pins which can grip the inside of the holes.
A USL-5P is shown with a modified little cable. The DB9 is glued into a slot
cut into the plastic between the ethernet and a USB port.
