1.1 deraadt 50: <p>
51: OpenBSD/landisk is the 1st OpenBSD port to a
52: <a href="http://www.renesas.com">Hitachi/Renesas</a> SH-4 based machine.
53: It is hoped that other SH-4 based machines will show up which are
54: interesting enough for our user and development community, but the SH-4
55: processor is normally used only in true embedded products.
56:
1.83 bentley 57: <p>
1.71 tb 58: This processor architecture is the first 32-bit successor of a series
1.39 sthen 59: of extremely bizarre 8 and 16 bit processors by Hitachi. It has a
1.33 deraadt 60: very strange instruction set and MMU, and developers find it quite a
61: challenge to map their knowledge of Unix low-level ideas to the
62: processor architecture.

1.19 nick 108: <strong>Serial cable connection</strong>
1.83 bentley 109: </h3>
1.4 deraadt 110: All of these machines require a special serial cable which does
111: voltage conversion, and can hopefully be purchased along with the
112: card. This cable normally contains a little max232 or similar chip
1.5 deraadt 113: which converts from the 3.3V signals to +/-12V. The IO-DATA cable
114: has pins which can grip the inside of the holes. Or you can attempt
1.4 deraadt 115: to build your own using
116: <a href="http://www.mizore.jp/wiki/index.php?LANDISK%2Fserial-console">
117: some Japanese instructions</a>.
1.83 bentley 118:
1.4 deraadt 119: <p>
1.6 deraadt 120: The IO-DATA cable converts from a DB9 connector to a 5-pin header
121: (3.3V Tx Rx GND NC). Note that the Rx and Tx pins on the board are
122: <b>swapped</b> compared to the ARM-based machines made by IO-DATA.
123: All the board models have a 5-pin connector (called CN7) which the cable
124: can plug into -- except for the USL-5P which has a 4-pin header (thus
125: requiring removal of the spare pin).
1.83 bentley 126:
1.4 deraadt 127: <p>
1.5 deraadt 128: A USL-5P is shown with a modified IO-DATA cable. In this case the cable
129: has been shortened significantly and the DB9 connector is glued into a slot
130: carefully cut into the plastic between the ethernet and a USB port.
