1.1 deraadt 61: <p>
62: OpenBSD/landisk is the 1st OpenBSD port to a
63: <a href="http://www.renesas.com">Hitachi/Renesas</a> SH-4 based machine.
64: It is hoped that other SH-4 based machines will show up which are
65: interesting enough for our user and development community, but the SH-4
66: processor is normally used only in true embedded products.
67:
1.44 miod 68: This processor architecture is the first 32-bit sucessor of a series
1.39 sthen 69: of extremely bizarre 8 and 16 bit processors by Hitachi. It has a
1.33 deraadt 70: very strange instruction set and MMU, and developers find it quite a
71: challenge to map their knowledge of Unix low-level ideas to the
72: processor architecture.

1.4 deraadt 130: </font></h3>
131: All of these machines require a special serial cable which does
132: voltage conversion, and can hopefully be purchased along with the
133: card. This cable normally contains a little max232 or similar chip
1.5 deraadt 134: which converts from the 3.3V signals to +/-12V. The IO-DATA cable
135: has pins which can grip the inside of the holes. Or you can attempt
1.4 deraadt 136: to build your own using
137: <a href="http://www.mizore.jp/wiki/index.php?LANDISK%2Fserial-console">
138: some Japanese instructions</a>.
139: <p>
1.6 deraadt 140: The IO-DATA cable converts from a DB9 connector to a 5-pin header
141: (3.3V Tx Rx GND NC). Note that the Rx and Tx pins on the board are
142: <b>swapped</b> compared to the ARM-based machines made by IO-DATA.
143: All the board models have a 5-pin connector (called CN7) which the cable
144: can plug into -- except for the USL-5P which has a 4-pin header (thus
145: requiring removal of the spare pin).
1.4 deraadt 146: <p>
1.5 deraadt 147: A USL-5P is shown with a modified IO-DATA cable. In this case the cable
148: has been shortened significantly and the DB9 connector is glued into a slot
149: carefully cut into the plastic between the ethernet and a USB port.
