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 IO-DATA cable converts from a DB9 connector to a 5-pin header (3.3V Tx Rx GND NC). Note that the Rx and Tx pins on the board are swapped compared to the ARM-based machines made by IO-DATA. All the board models have a 5-pin connector (called CN7) which the cable can plug into -- except for the USL-5P which has a 4-pin header (thus requiring removal of the spare pin).
A USL-5P is shown with a modified IO-DATA cable. In this case the cable
has been shortened significantly and the DB9 connector is glued into a slot
carefully cut into the plastic between the ethernet and a USB port.
