Downloading via Ethernet requires your target board to be equipped with
an Ethernet controller and your <a href="mondef.htm">Monitor</a> to
contain Ethernet support.

To download via Ethernet, perform the following steps:
<p>
</dl><h2>UNIX Hosts</h2><dl><dd>
<ol>
<li>
Choose an IP address and a host name for your target board and enter 
them in your UNIX host's /etc/hosts file. For example,<p>

<pre>
    71.0.0.208 umeteor	# IP address for LSI uMeteor board
</pre><p>

<li> Use the <a href="c_set.htm">set</a> command to set the IP
address of your target board:<p>

<pre>
    PMON> set ipaddr 71.0.0.208
</pre><p>

Note: It is no longer necessary to manually set the arp table, because
the <a href="mondef.htm">Monitor</a> now responds to arp requests from the
host.<p>

<li> If you have more than one board on the network, the Ethernet
hardware (MAC) address can be changed using the set command. For example,<p>

<pre>
    PMON> set etheraddr aa:bb:cc:00:00:01
</pre><p>

<li>Now set the environment variable hostport to ethernet:<p>

<pre>
    PMON> set hostport ethernet
</pre><p>

<li> At this point you might want to use the set nvram command to make 
these new settings permanent:<p>

<pre>
    PMON> set nvram
</pre><p>

<li> To download <a href="frec.htm">Fast-Format</a> or <a
href="srec.htm">S-record</a> files, enter the following commands:<p>

<dl><dd>
<table>

<tr><td width=300 nowrap valign=top>
<tt>PMON> <a href="c_load.htm">load</a></tt></td>
<td>Prepare for download.</td></tr>

<tr><td nowrap valign=top><tt>% tftp umeteor</tt></td>
<td>Invoke tftp for umeteor system.</td></tr>

<tr><td nowrap valign=top><tt>tftp> put game.rec</tt></td>
<td>Send file game.rec to umeteor.</td></tr>

<tr><td nowrap valign=top><tt>tftp> quit</tt></td>
<td>Exit to shell.</td></tr>
</table></dl><p>

The transfer rate is approximately 134 Kbytes/second. 
<p>

<li> To download binary files, enter the following commands:<p>

<dl><dd>
<table>
<tr><td width=300 nowrap valign=top><tt>
PMON> <a href="c_load.htm">load</a> -B
</tt></td><td>
Use binary format for tftp transfer.
</td></tr>

<tr><td nowrap valign=top><tt>
% tftp umeteor
</tt></td><td>
Invoke tftp for umeteor system.
</td></tr>

<tr><td nowrap valign=top><tt>
tftp> mode binary
</tt></td><td>
Put tftp in binary mode to prevent it from translating "\n" to "\r\n".
</td></tr>

<tr><td nowrap valign=top><tt>
tftp> put foobar 80040000
</tt></td><td>
Send foobar to umeteor starting at address.
</td></tr>

<tr><td nowrap valign=top><tt>
tftp> quit
</tt></td><td>
Exit to shell.
</td></tr>
</table></dl><p>

The transfer rate for binary files is approximately l50 Kbytes/second.<p>

Because the <a href="mondef.htm">Monitor</a> uses only the UDP
protocol, you must use tftp's put command for downloading; the tftp get
command is not supported. Note that we used PMON for this example, but
the procedure is exactly the same for the SerialICE Monitor.<p>
</ol>


</dl><h2>Windows95/NT Hosts</h2><dl><dd>

<ol>
<li>Install the Microsoft TCP/IP package or equivalent.<p>
<li> Choose an IP address and a host name for your host and your target
board and enter them into the file \WINDOWS\HOSTS on your host. For
example, if you host was named "ctx1" and your target "umeteor", you
might enter the following information. <p>

<pre>
    71.0.0.208 umeteor
    71.0.0.214 ctx1 loghost
</pre>

The keyword 'loghost' must be used to indicate which line contains the
name of your host.  If you are not using Microsoft's TCP/IP
package, please refer to the vendor's documentation for the location of
the HOSTS file. In that case you might need to modify the <a
href="perl.htm">Perl</a> script <a
href="tools/tftp-put.htm">tftp-put</a>.<p>

<li> Use the <a href="c_set.htm">set</a> command to set the IP
address of your target board:<p>

<pre>
    PMON> <a href="c_set.htm">set</a> ipaddr 71.0.0.208
</pre><p>

<li> If you have more than one board on the network, the Ethernet
hardware (MAC) address can be changed using the set command. For example,<p>

<pre>
    PMON> set etheraddr aa:bb:cc:00:00:01
</pre>

<li>Now set the environment variable hostport to ethernet:<p>

<pre>
    PMON> set hostport ethernet
</pre>

<li> At this point you might want to use the set nvram command to make 
these new settings permanent:<p>

<pre>
    PMON> set nvram
</pre>

<li> To download <a href="frec.htm">Fast-Format</a> or <a
href="srec.htm">S-record</a> files, enter the following commands:<p>

<dl><dd>
<table>

<tr><td width=300 nowrap valign=top>
<tt>PMON> <a href="c_load.htm">load</a></tt></td>
<td>Prepare for download.</td></tr>

<tr><td nowrap valign=top><tt>C><a href="perl.htm">perl</a> <a
href="tools/tftp-put.htm">tftp-put</a> umeteor game.rec</tt></td>
<td>Send file game.rec to umeteor.

</td></tr></table></dl><p>

The transfer rate is approximately 134 Kbytes/second. <p>
</ul>

</dl><h2>Notes</h2><dl><dd>

<ul>
<li>If you already have a permanant arp entry for your board, you need
not set the ipaddr variable. This is only used when responding to arp
requests from the host.<p>

<li>Once you have typed 'load', the <a href="mondef.htm">Monitor</a>
will respond to <a href="pingdef.htm">ping</a> requests from the host.
However, do not issue ping requests while the tftp transfer is
running.  The Monitor will not respond to ping requests once control
has returned to the PMON prompt.  <p>

</ul>
