1.1 deraadt 68: <p>
69: OpenBSD/landisk is the 1st OpenBSD port to a
70: <a href="http://www.renesas.com">Hitachi/Renesas</a> SH-4 based machine.
71: It is hoped that other SH-4 based machines will show up which are
72: interesting enough for our user and development community, but the SH-4
73: processor is normally used only in true embedded products.
74:
1.44 miod 75: This processor architecture is the first 32-bit sucessor of a series
1.39 sthen 76: of extremely bizarre 8 and 16 bit processors by Hitachi. It has a
1.33 deraadt 77: very strange instruction set and MMU, and developers find it quite a
78: challenge to map their knowledge of Unix low-level ideas to the
79: processor architecture.

1.19 nick 137: <strong>Serial cable connection</strong>
1.4 deraadt 138: </font></h3>
139: All of these machines require a special serial cable which does
140: voltage conversion, and can hopefully be purchased along with the
141: card. This cable normally contains a little max232 or similar chip
1.5 deraadt 142: which converts from the 3.3V signals to +/-12V. The IO-DATA cable
143: has pins which can grip the inside of the holes. Or you can attempt
1.4 deraadt 144: to build your own using
145: <a href="http://www.mizore.jp/wiki/index.php?LANDISK%2Fserial-console">
146: some Japanese instructions</a>.
147: <p>
1.6 deraadt 148: The IO-DATA cable converts from a DB9 connector to a 5-pin header
149: (3.3V Tx Rx GND NC). Note that the Rx and Tx pins on the board are
150: <b>swapped</b> compared to the ARM-based machines made by IO-DATA.
151: All the board models have a 5-pin connector (called CN7) which the cable
152: can plug into -- except for the USL-5P which has a 4-pin header (thus
153: requiring removal of the spare pin).
1.4 deraadt 154: <p>
1.5 deraadt 155: A USL-5P is shown with a modified IO-DATA cable. In this case the cable
156: has been shortened significantly and the DB9 connector is glued into a slot
157: carefully cut into the plastic between the ethernet and a USB port.
