Revision 1.83, Mon May 27 22:55:20 2019 UTC (5 years ago) by bentley
Substantially clean up and modernize HTML markup across openbsd.org. This was done with three purposes in mind: - to reduce the massive amount of inline HTML, to be easier on developers adding actual content - to allow running the HTML validator across the source (doing this found many unintentional mistakes in the present code, including at least a dozen cases of half- or fully-invisible text) - to separate content from presentation, so appearance can be controlled through stylesheets Great care was taken to keep all pages, even very old ones, looking the same, give or take a few pixels of whitespace. Much review, critique, and improvement from tj@ |

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. <p> This processor architecture is the first 32-bit successor of a series of extremely bizarre 8 and 16 bit processors by Hitachi. It has a very strange instruction set and MMU, and developers find it quite a challenge to map their knowledge of Unix low-level ideas to the processor architecture. <h3 id="status"><strong>Current status</strong></h3> <p> Hardware support is mostly complete and quite stable. <h3 id="hardware"><strong>Supported hardware</strong></h3> <p> For a complete system component and device driver listing for this architecture, see <a href="https://man.openbsd.org/landisk/intro.4">intro(4/landisk)</a>. <ul> <li>HITACHI SH4 SH7751R processor at 266MHz. <li>64MB of ram. <li><a href="https://man.openbsd.org/re.4">re(4)</a> 100Mbit ethernet. <li><a href="https://man.openbsd.org/wdc.4">wdc(4)</a> drive controller connected to either flash or microdrive in a CF socket, on some models. <li><a href="https://man.openbsd.org/pciide.4">pciide(4)</a> IDE drive controller supporting <a href="https://man.openbsd.org/wd.4">wd(4)</a>, on some models. <li><a href="https://man.openbsd.org/com.4">com(4)</a> serial port console at 9600 baud (lacking hardware flow control). <li><a href="https://man.openbsd.org/ehci.4">ehci(4)</a> and <a href="https://man.openbsd.org/ohci.4">ohci(4)</a> USB controllers supporting most <a href="https://man.openbsd.org/usb.4">usb(4)</a> devices. <li><a href="https://man.openbsd.org/landisk/power.4">power(4)</a> button and some LEDs. </ul> <h3 id="install"> <strong>Getting and installing</strong> </h3> <p> The latest supported OpenBSD/landisk release is <a href="65.html">OpenBSD 6.5</a>. Here are the <a href="https://ftp.openbsd.org/pub/OpenBSD/6.5/landisk/INSTALL.landisk"> OpenBSD/landisk installation instructions</a>. <p> Snapshots are made available from time to time, in <a href="https://cdn.openbsd.org/pub/OpenBSD/snapshots/landisk">this location</a> as well as on a few <a href="ftp.html">mirrors</a>. Here are the <a href="https://ftp.openbsd.org/pub/OpenBSD/snapshots/landisk/INSTALL.landisk"> OpenBSD/landisk snapshot installation instructions</a> as well. <img height=274 width=410 src="images/usl5p-serial.gif" alt="usl5p serial" style="float: right"> <h3 id="serial"> <strong>Serial cable connection</strong> </h3> All of these machines require a special serial cable which does voltage conversion, and can hopefully be purchased along with the card. This cable normally contains a little max232 or similar chip which converts from the 3.3V signals to +/-12V. The IO-DATA cable has pins which can grip the inside of the holes. Or you can attempt to build your own using <a href="http://www.mizore.jp/wiki/index.php?LANDISK%2Fserial-console"> some Japanese instructions</a>. <p> 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 <b>swapped</b> 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). <p> 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.
