<h2 class="section">3.1 Terminal Mode Commands</h2>
|
|
|
|
<p>The following commands are implemented:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>dump <var>memtype</var> <var>addr</var> <var>nbytes</var></code></dt>
|
|
<dd><p>Read <var>nbytes</var> from the specified memory area, and display them in
|
|
the usual hexadecimal and ASCII form.
|
|
</p>
|
|
</dd>
|
|
<dt><code>dump</code></dt>
|
|
<dd><p>Continue dumping the memory contents for another <var>nbytes</var> where the
|
|
previous dump command left off.
|
|
</p>
|
|
</dd>
|
|
<dt><code>write <var>memtype</var> <var>addr</var> <var>byte1</var> … <var>byteN</var></code></dt>
|
|
<dd><p>Manually program the respective memory cells, starting at address addr,
|
|
using the values <var>byte1</var> through <var>byteN</var>. This feature is not
|
|
implemented for bank-addressed memories such as the flash memory of
|
|
ATMega devices.
|
|
</p>
|
|
</dd>
|
|
<dt><code>erase</code></dt>
|
|
<dd><p>Perform a chip erase.
|
|
</p>
|
|
</dd>
|
|
<dt><code>send <var>b1</var> <var>b2</var> <var>b3</var> <var>b4</var></code></dt>
|
|
<dd><p>Send raw instruction codes to the AVR device. If you need access to a
|
|
feature of an AVR part that is not directly supported by AVRDUDE, this
|
|
command allows you to use it, even though AVRDUDE does not implement the
|
|
command. When using direct SPI mode, up to 3 bytes
|
|
can be omitted.
|
|
</p>
|
|
</dd>
|
|
<dt><code>sig</code></dt>
|
|
<dd><p>Display the device signature bytes.
|
|
</p>
|
|
</dd>
|
|
<dt><code>spi</code></dt>
|
|
<dd><p>Enter direct SPI mode. The <em>pgmled</em> pin acts as slave select.
|
|
<em>Only supported on parallel bitbang programmers, and partially by USBtiny.</em>
|
|
Slave Select must be externally held low for direct SPI when
|
|
using USBtinyISP, and send must be a multiple of four bytes.
|
|
</p>
|
|
</dd>
|
|
<dt><code>part</code></dt>
|
|
<dd><p>Display the current part settings and parameters. Includes chip
|
|
specific information including all memory types supported by the
|
|
device, read/write timing, etc.
|
|
</p>
|
|
</dd>
|
|
<dt><code>pgm</code></dt>
|
|
<dd><p>Return to programming mode (from direct SPI mode).
|
|
</p>
|
|
</dd>
|
|
<dt><code>verbose [<var>level</var>]</code></dt>
|
|
<dd><p>Change (when <var>level</var> is provided), or display the verbosity
|
|
level.
|
|
The initial verbosity level is controlled by the number of <code>-v</code> options
|
|
given on the command line.
|
|
</p>
|
|
</dd>
|
|
<dt><code>?</code></dt>
|
|
<dt><code>help</code></dt>
|
|
<dd><p>Give a short on-line summary of the available commands.
|
|
</p>
|
|
</dd>
|
|
<dt><code>quit</code></dt>
|
|
<dd><p>Leave terminal mode and thus AVRDUDE.
|
|
</p>
|
|
</dd>
|
|
</dl>
|
|
|
|
<p>In addition, the following commands are supported on the STK500
|
|
and STK600 programmer:
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>vtarg <var>voltage</var></code></dt>
|
|
<dd><p>Set the target’s supply voltage to <var>voltage</var> Volts.
|
|
</p>
|
|
</dd>
|
|
<dt><code>varef [<var>channel</var>] <var>voltage</var></code></dt>
|
|
<dd><p>Set the adjustable voltage source to <var>voltage</var> Volts.
|
|
This voltage is normally used to drive the target’s
|
|
<em>Aref</em> input on the STK500 and STK600.
|
|
The STK600 offers two reference voltages, which can be
|
|
selected by the optional parameter <var>channel</var> (either
|
|
0 or 1).
|
|
</p>
|
|
</dd>
|
|
<dt><code>fosc <var>freq</var>[<code>M</code>|<code>k</code>]</code></dt>
|
|
<dd><p>Set the master oscillator to <var>freq</var> Hz.
|
|
An optional trailing letter <code>M</code>
|
|
multiplies by 1E6, a trailing letter <code>k</code> by 1E3.
|
|
</p>
|
|
</dd>
|
|
<dt><code>fosc off</code></dt>
|
|
<dd><p>Turn the master oscillator off.
|
|
</p>
|
|
</dd>
|
|
<dt><code>sck <var>period</var></code></dt>
|
|
<dd><p><em>STK500 and STK600 only:</em>
|
|
Set the SCK clock period to <var>period</var> microseconds.
|
|
</p>
|
|
<p><em>JTAG ICE only:</em>
|
|
Set the JTAG ICE bit clock period to <var>period</var> microseconds.
|
|
Note that unlike STK500 settings, this setting will be reverted to
|
|
its default value (approximately 1 microsecond) when the programming
|
|
software signs off from the JTAG ICE.
|
|
This parameter can also be used on the JTAG ICE mkII/3 to specify the
|
|
ISP clock period when operating the ICE in ISP mode.
|
|
</p>
|
|
</dd>
|
|
<dt><code>parms</code></dt>
|
|
<dd><p><em>STK500 and STK600 only:</em>
|
|
Display the current voltage and master oscillator parameters.
|
|
</p>
|
|
<p><em>JTAG ICE only:</em>
|
|
Display the current target supply voltage and JTAG bit clock rate/period.
|
|
</p>
