<h3 class="subsection">4.3.2 Instruction Format</h3>
<p>Instruction formats are specified as a comma separated list of string
values containing information (bit specifiers) about each of the 32 bits
of the instruction. Bit specifiers may be one of the following formats:
</p>
<dl compact="compact">
<dt><code>1</code></dt>
<dd><p>The bit is always set on input as well as output
</p>
</dd>
<dt><code>0</code></dt>
<dd><p>the bit is always clear on input as well as output
</p>
</dd>
<dt><code>x</code></dt>
<dd><p>the bit is ignored on input and output
</p>
</dd>
<dt><code>a</code></dt>
<dd><p>the bit is an address bit, the bit-number matches this bit specifier&rsquo;s
position within the current instruction byte
</p>
</dd>
<dt><code>a<var>N</var></code></dt>
<dd><p>the bit is the <var>N</var>th address bit, bit-number = N, i.e., <code>a12</code>
is address bit 12 on input, <code>a0</code> is address bit 0.
</p>
</dd>
<dt><code>i</code></dt>
<dd><p>the bit is an input data bit
</p>
</dd>
<dt><code>o</code></dt>
<dd><p>the bit is an output data bit
</p>
</dd>
</dl>
<p>Each instruction must be composed of 32 bit specifiers. The instruction
specification closely follows the instruction data provided in Atmel&rsquo;s
data sheets for their parts. For example, the EEPROM read and write
instruction for an AT90S2313 AVR part could be encoded as:
</p>

<p>Parts can also inherit parameters from previously defined parts

The <code>devicecode</code> parameter is the device code used by the STK500 memory definitions are added to the definitions inherited from the

Atmel&rsquo;s AVR061 application note available from

</li><li>
Not all memory types will implement all instructions.
</li><li>
AVR Fuse bits and Lock bits are implemented as a type of memory.
</li><li>
Example memory types are: <code>flash</code>, <code>eeprom</code>, <code>fuse</code>,
<code>lfuse</code> (low fuse), <code>hfuse</code> (high fuse), <code>efuse</code>
(extended fuse), <code>signature</code>, <code>calibration</code>, <code>lock</code>.
</li><li>
The memory type specified on the AVRDUDE command line must match one of
the memory types defined for the specified chip.
</li><li>
The <code>pwroff_after_write</code> flag causes AVRDUDE to attempt to power
the device off and back on after an unsuccessful write to the affected
memory area if VCC programmer pins are defined. If VCC pins are not
defined for the programmer, a message indicating that the device needs a
power-cycle is printed out. This flag was added to work around a
problem with the at90s4433/2333&rsquo;s; see the at90s4433 errata at:
<p> <a href="http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf">http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf</a>

The boot loader from application note AVR109 (and thus also the AVR <pre class="smallexample"> part parent &lt;id&gt; # quoted string
Butterfly) does not support writing of fuse bits. Writing lock bits id = &lt;id&gt; ; # quoted string
is supported, but is restricted to the boot lock bits (BLBxx). These &lt;any set of other parameters from the list above&gt;
are restrictions imposed by the underlying SPM instruction that is used ;
to program the device from inside the boot loader. Note that programming </pre></div>
the boot lock bits can result in a &ldquo;shoot-into-your-foot&rdquo; scenario as
the only way to unprogram these bits is a chip erase, which will also
erase the boot loader code.
<p>The boot loader implements the &ldquo;chip erase&rdquo; function by erasing the
flash pages of the application section.
</p>
<p>Reading fuse and lock bits is fully supported.

pinout with Vcc and GND at opposite corners). Not all memory types will implement all instructions.
</li><li>
AVR Fuse bits and Lock bits are implemented as a type of memory.
</li><li>
Example memory types are: <code>flash</code>, <code>eeprom</code>, <code>fuse</code>,
<code>lfuse</code> (low fuse), <code>hfuse</code> (high fuse), <code>efuse</code>
(extended fuse), <code>signature</code>, <code>calibration</code>, <code>lock</code>.
</li><li>
The memory type specified on the AVRDUDE command line must match one of
the memory types defined for the specified chip.
</li><li>
The <code>pwroff_after_write</code> flag causes AVRDUDE to attempt to power
the device off and back on after an unsuccessful write to the affected
memory area if VCC programmer pins are defined. If VCC pins are not
defined for the programmer, a message indicating that the device needs a
power-cycle is printed out. This flag was added to work around a
problem with the at90s4433/2333&rsquo;s; see the at90s4433 errata at:

are restrictions imposed by the underlying SPM instruction that is used
to program the device from inside the boot loader. Note that programming
the boot lock bits can result in a &ldquo;shoot-into-your-foot&rdquo; scenario as
the only way to unprogram these bits is a chip erase, which will also
erase the boot loader code.
<p>The boot loader implements the &ldquo;chip erase&rdquo; function by erasing the
flash pages of the application section.

and other wiring errors. AVRDUDE initiates a connection check before
trying to enter ISP programming mode, and display the result if the
target is not found ready to be ISP programmed.

<p>High-voltage programming requires the target voltage to be set to at
least 4.5 V in order to work. This can be done using
<em>Terminal Mode</em>, see <a href="avrdude_6.html#Terminal-Mode-Operation">Terminal Mode Operation</a>.

<h2 class="section">5.2 Atmel DFU bootloader using FLIP version 1</h2>
<p>Bootloaders using the FLIP protocol version 1 experience some very
specific behaviour.
</p>
<p>These bootloaders have no option to access memory areas other than
Flash and EEPROM.
</p>
<p>When the bootloader is started, it enters a <em>security mode</em> where
the only acceptable access is to query the device configuration
parameters (which are used for the signature on AVR devices). The
only way to leave this mode is a <em>chip erase</em>. As a chip erase
is normally implied by the &lsquo;<samp>-U</samp>&rsquo; option when reprogramming the
flash, this peculiarity might not be very obvious immediately.
</p>
<p>Sometimes, a bootloader with security mode already disabled seems to
no longer respond with sensible configuration data, but only 0xFF for
all queries. As these queries are used to obtain the equivalent of a
signature, AVRDUDE can only continue in that situation by forcing the
signature check to be overridden with the &lsquo;<samp>-F</samp>&rsquo; option.
</p>
<p>A <em>chip erase</em> might leave the EEPROM unerased, at least on some
versions of the bootloader.

<p>There are several limitations in current SerialUPDI/AVRDUDE integration, <p>Ensure the correct socket and routing card are mounted <em>before</em>
listed below. powering on the STK600. While the STK600 firmware ensures the socket
and routing card mounted match each other (using a table stored
internally in nonvolatile memory), it cannot handle the case where a
wrong routing card is used, e. g. the routing card
<code>STK600-RC040M-5</code> (which is meant for 40-pin DIP AVRs that have
an ADC, with the power supply pins in the center of the package) was
used but an ATmega8515 inserted (which uses the &ldquo;industry standard&rdquo;
pinout with Vcc and GND at opposite corners).
</p> </p>
<p>At the end of each run there are fuse values being presented to the user. <p>Note that for devices that use the routing card <code>STK600-RC008T-2</code>,
For most of the UPDI-enabled devices these definitions (low fuse, high in order to use ISP mode, the jumper for <code>AREF0</code> must be removed
fuse, extended fuse) have no meaning whatsoever, as they have been as it would otherwise block one of the ISP signals. High-voltage
simply replaced by array of fuses: fuse0..9. Therefore you can simply serial programming can be used even with that jumper installed.
ignore this particular line of AVRDUDE output.
</p> </p>
<p>Currently available devices support only UPDI NVM programming model 0 <p>The ISP system of the STK600 contains a detection against shortcuts
and 2, but there is also experimental implementation of model 3 - not and other wiring errors. AVRDUDE initiates a connection check before
yet tested. trying to enter ISP programming mode, and display the result if the
target is not found ready to be ISP programmed.
</p> </p>
<p>One of the core AVRDUDE features is verification of the connection by <p>High-voltage programming requires the target voltage to be set to at
reading device signature prior to any operation, but this operation least 4.5 V in order to work. This can be done using
is not possible on UPDI locked devices. Therefore, to be able to <em>Terminal Mode</em>, see <a href="avrdude_6.html#Terminal-Mode-Operation">Terminal Mode Operation</a>.
connect to such a device, you have to provide &lsquo;<samp>-F</samp>&rsquo; to override
this check.
</p>
<p>Please note: using &lsquo;<samp>-F</samp>&rsquo; during write operation to locked device
will force chip erase. Use carefully.
</p>
<p>Another issue you might notice is slow performance of EEPROM writing
using SerialUPDI for AVR Dx devices. This can be addressed by changing
<em>avrdude.conf</em> section for this device - changing EEPROM page
size to 0x20 (instead of default 1), like so:
</p>
<div class="example">
<pre class="example">#------------------------------------------------------------
# AVR128DB28
#------------------------------------------------------------
part parent &quot;.avrdx&quot;
id = &quot;avr128db28&quot;;
desc = &quot;AVR128DB28&quot;;
signature = 0x1E 0x97 0x0E;
memory &quot;flash&quot;
size = 0x20000;
offset = 0x800000;
page_size = 0x200;
readsize = 0x100;
;
memory &quot;eeprom&quot;
size = 0x200;
offset = 0x1400;
page_size = 0x1;
readsize = 0x100;
;
;
</pre></div>
<p>USERROW memory has not been defined for new devices except for
experimental addition for AVR128DB28. The point of USERROW is to
provide ability to write configuration details to already locked
device and currently SerialUPDI interface supports this feature,
but it hasn&rsquo;t been tested on wide variety of chips. Treat this as
something experimental at this point. Please note: on locked devices
it&rsquo;s not possible to read back USERROW contents when written, so
the automatic verification will most likely fail and to prevent
error messages, use &lsquo;<samp>-V</samp>&rsquo;.
</p>
<p>Please note that SerialUPDI interface is pretty new and some
issues are to be expected. In case you run into them, please
make sure to run the intended command with debug output enabled
(&lsquo;<samp>-v -v -v</samp>&rsquo;) and provide this verbose output with your
bug report. You can also try to perform the same action using
<em>pymcuprog</em> (<a href="https://github.com/microchip-pic-avr-tools/pymcuprog">https://github.com/microchip-pic-avr-tools/pymcuprog</a>)
utility with &lsquo;<samp>-v debug</samp>&rsquo; and provide its output too.
You will notice that both outputs are pretty similar, and this
was implemented like that on purpose - it was supposed to make
analysis of UPDI protocol quirks easier.

</tr></table> <p>These bootloaders have no option to access memory areas other than
Flash and EEPROM.
</p>
<p>When the bootloader is started, it enters a <em>security mode</em> where
the only acceptable access is to query the device configuration
parameters (which are used for the signature on AVR devices). The
only way to leave this mode is a <em>chip erase</em>. As a chip erase
is normally implied by the &lsquo;<samp>-U</samp>&rsquo; option when reprogramming the
flash, this peculiarity might not be very obvious immediately.
</p>
<p>Sometimes, a bootloader with security mode already disabled seems to
no longer respond with sensible configuration data, but only 0xFF for
all queries. As these queries are used to obtain the equivalent of a
signature, AVRDUDE can only continue in that situation by forcing the
signature check to be overridden with the &lsquo;<samp>-F</samp>&rsquo; option.
</p>
<p>A <em>chip erase</em> might leave the EEPROM unerased, at least on some
versions of the bootloader.

<h3 class="subsection">A.1.1 Unix Installation</h3>
<p>To build and install from the source tarball on Unix like systems: <p>SerialUPDI programmer can be used for programming UPDI-only devices
using very simple serial connection.
You can read more about the details here
<a href="https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md">https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md</a>
</p>
<p>SerialUPDI programmer has been tested using FT232RL USB-&gt;UART interface
with the following connection layout (copied from Spence Kohde&rsquo;s page linked
above):
</p> </p>
<div class="example"> <div class="example">

<p>If you do not have root access to your system, you can do the <p>At the end of each run there are fuse values being presented to the user.
following instead: For most of the UPDI-enabled devices these definitions (low fuse, high
fuse, extended fuse) have no meaning whatsoever, as they have been
simply replaced by array of fuses: fuse0..9. Therefore you can simply
ignore this particular line of AVRDUDE output.
</p>
<p>Currently available devices support only UPDI NVM programming model 0
and 2, but there is also experimental implementation of model 3 - not
yet tested.
</p>
<p>One of the core AVRDUDE features is verification of the connection by
reading device signature prior to any operation, but this operation
is not possible on UPDI locked devices. Therefore, to be able to
connect to such a device, you have to provide &lsquo;<samp>-F</samp>&rsquo; to override
this check.
</p>
<p>Please note: using &lsquo;<samp>-F</samp>&rsquo; during write operation to locked device
will force chip erase. Use carefully.
</p>
<p>Another issue you might notice is slow performance of EEPROM writing
using SerialUPDI for AVR Dx devices. This can be addressed by changing
<em>avrdude.conf</em> section for this device - changing EEPROM page
size to 0x20 (instead of default 1), like so:
</p> </p>

</table> something experimental at this point. Please note: on locked devices
it&rsquo;s not possible to read back USERROW contents when written, so
the automatic verification will most likely fail and to prevent
error messages, use &lsquo;<samp>-V</samp>&rsquo;.
</p>
<p>Please note that SerialUPDI interface is pretty new and some
issues are to be expected. In case you run into them, please
make sure to run the intended command with debug output enabled
(&lsquo;<samp>-v -v -v</samp>&rsquo;) and provide this verbose output with your
bug report. You can also try to perform the same action using
<em>pymcuprog</em> (<a href="https://github.com/microchip-pic-avr-tools/pymcuprog">https://github.com/microchip-pic-avr-tools/pymcuprog</a>)
utility with &lsquo;<samp>-v debug</samp>&rsquo; and provide its output too.
You will notice that both outputs are pretty similar, and this
was implemented like that on purpose - it was supposed to make
analysis of UPDI protocol quirks easier.

<h3 class="subsection">A.2.1 Installation</h3>
<p>A Windows executable of avrdude is included in WinAVR which can be found at
<a href="http://sourceforge.net/projects/winavr">http://sourceforge.net/projects/winavr</a>. WinAVR is a suite of executable,
open source software development tools for the AVR for the Windows platform.
</p>
<p>There are two options to build avrdude from source under Windows.
The first one is to use Cygwin (<a href="http://www.cygwin.com/">http://www.cygwin.com/</a>).
</p>
<p>To build and install from the source tarball for Windows (using Cygwin):
</p>
<div class="example">
<pre class="example">$ set PREFIX=&lt;your install directory path&gt;
$ export PREFIX
$ gunzip -c avrdude-6.99-20211218.tar.gz | tar xf -
$ cd avrdude-6.99-20211218
$ ./configure LDFLAGS=&quot;-static&quot; --prefix=$PREFIX --datadir=$PREFIX
--sysconfdir=$PREFIX/bin --enable-versioned-doc=no
$ make
$ make install
</pre></div>
<p>Note that recent versions of Cygwin (starting with 1.7) removed the
MinGW support from the compiler that is needed in order to build a
native Win32 API binary that does not require to install the Cygwin
library <code>cygwin1.dll</code> at run-time. Either try using an older
compiler version that still supports MinGW builds, or use MinGW
(<a href="http://www.mingw.org/">http://www.mingw.org/</a>) directly.

<p>AVRDUDE on Windows has a different way of searching for the system and
user configuration files. Below is the search method for locating the
configuration files:
</p>
<ol>
<li>
Only for the system configuration file:
<code>&lt;directory from which application loaded&gt;/../etc/avrdude.conf</code>
</li><li>
The directory from which the application loaded.
</li><li>
The current directory.
</li><li>
The Windows system directory. On Windows NT, the name of this directory
is <code>SYSTEM32</code>.
</li><li>
Windows NT: The 16-bit Windows system directory. The name of this
directory is <code>SYSTEM</code>.
</li><li>
The Windows directory.
</li><li>
The directories that are listed in the PATH environment variable.

<p>AVRDUDE will accept 3 Windows parallel port names: lpt1, lpt2, or
lpt3. Each of these names corresponds to a fixed parallel port base
address:
</p>
<dl compact="compact">
<dt><code>lpt1</code></dt>
<dd><p>0x378
</p>
</dd>
<dt><code>lpt2</code></dt>
<dd><p>0x278

</dd>
<dt><code>lpt3</code></dt>
<dd><p>0x3BC
</p>
</dd>
</dl>
<p>On your desktop PC, lpt1 will be the most common choice. If you are
using a laptop, you might have to use lpt3 instead of lpt1. Select the
name of the port the corresponds to the base address of the parallel
port that you want.
</p>
<p>If the parallel port can be accessed through a different
address, this address can be specified directly, using the common C
language notation (i. e., hexadecimal values are prefixed by <code>0x</code>).

Problem: I&rsquo;m using a serial programmer under Windows and get the following <tr><td align="left" valign="top"><a href="avrdude_29.html#Unix-Documentation">A.1.4 Unix Documentation</a></td><td>&nbsp;&nbsp;</td><td align="left" valign="top">
error: </td></tr>
<p><code>avrdude: serial_open(): can't set attributes for device &quot;com1&quot;</code>,
</p>
<p>Solution: This problem seems to appear with certain versions of Cygwin. Specifying
<code>&quot;/dev/com1&quot;</code> instead of <code>&quot;com1&quot;</code> should help.
</p>
</li><li>
Problem: I&rsquo;m using Linux and my AVR910 programmer is really slow.
<p>Solution (short): <code>setserial <var>port</var> low_latency</code>
</p>
<p>Solution (long):
There are two problems here. First, the system may wait some time before it
passes data from the serial port to the program. Under Linux the following
command works around this (you may need root privileges for this).
</p>
<p><code>setserial <var>port</var> low_latency</code>
</p>
<p>Secondly, the serial interface chip may delay the interrupt for some time.
This behaviour can be changed by setting the FIFO-threshold to one. Under Linux this
can only be done by changing the kernel source in <code>drivers/char/serial.c</code>.
Search the file for <code>UART_FCR_TRIGGER_8</code> and replace it with <code>UART_FCR_TRIGGER_1</code>. Note that overall performance might suffer if there
is high throughput on serial lines. Also note that you are modifying the kernel at
your own risk.
</p>
</li><li>
Problem: I&rsquo;m not using Linux and my AVR910 programmer is really slow.
<p>Solutions: The reasons for this are the same as above.
If you know how to work around this on your OS, please let us know.
</p>
</li><li>
Problem: Updating the flash ROM from terminal mode does not work with the
JTAG ICEs.
<p>Solution: None at this time. Currently, the JTAG ICE code cannot
write to the flash ROM one byte at a time.
</p>
</li><li>
Problem: Page-mode programming the EEPROM (using the -U option) does
not erase EEPROM cells before writing, and thus cannot overwrite any
previous value != 0xff.
<p>Solution: None. This is an inherent feature of the way JTAG EEPROM
programming works, and is documented that way in the Atmel AVR
datasheets.
In order to successfully program the EEPROM that way, a prior chip
erase (with the EESAVE fuse unprogrammed) is required.
This also applies to the STK500 and STK600 in high-voltage programming mode.
</p>
</li><li>
Problem: How do I turn off the <var>DWEN</var> fuse?
<p>Solution: If the <var>DWEN</var> (debugWire enable) fuse is activated,
the <var>/RESET</var> pin is not functional anymore, so normal ISP
communication cannot be established.
There are two options to deactivate that fuse again: high-voltage
programming, or getting the JTAG ICE mkII talk debugWire, and
prepare the target AVR to accept normal ISP communication again.
</p>
<p>The first option requires a programmer that is capable of high-voltage
programming (either serial or parallel, depending on the AVR device),
for example the STK500. In high-voltage programming mode, the
<var>/RESET</var> pin is activated initially using a 12 V pulse (thus the
name <em>high voltage</em>), so the target AVR can subsequently be
reprogrammed, and the <var>DWEN</var> fuse can be cleared. Typically, this
operation cannot be performed while the AVR is located in the target
circuit though.
</p>
<p>The second option requires a JTAG ICE mkII that can talk the debugWire
protocol. The ICE needs to be connected to the target using the
JTAG-to-ISP adapter, so the JTAG ICE mkII can be used as a debugWire
initiator as well as an ISP programmer. AVRDUDE will then be activated
using the <var>jtag2isp</var> programmer type. The initial ISP
communication attempt will fail, but AVRDUDE then tries to initiate a
debugWire reset. When successful, this will leave the target AVR in a
state where it can accept standard ISP communication. The ICE is then
signed off (which will make it signing off from the USB as well), so
AVRDUDE has to be called again afterwards. This time, standard ISP
communication can work, so the <var>DWEN</var> fuse can be cleared.
</p>
<p>The pin mapping for the JTAG-to-ISP adapter is:
</p>
<table>
<tr><td width="20%"><strong>JTAG pin</strong></td><td width="20%"><strong>ISP pin</strong></td></tr>
<tr><td width="20%">1</td><td width="20%">3</td></tr>
<tr><td width="20%">2</td><td width="20%">6</td></tr>
<tr><td width="20%">3</td><td width="20%">1</td></tr>
<tr><td width="20%">4</td><td width="20%">2</td></tr>
<tr><td width="20%">6</td><td width="20%">5</td></tr>
<tr><td width="20%">9</td><td width="20%">4</td></tr>
</table> </table>
</li><li>
Problem: Multiple USBasp or USBtinyISP programmers connected simultaneously are not
found.
<p>Solution: The USBtinyISP code supports distinguishing multiple
programmers based on their bus:device connection tuple that describes
their place in the USB hierarchy on a specific host. This tuple can
be added to the <var>-P usb</var> option, similar to adding a serial number
on other USB-based programmers.
</p>
<p>The actual naming convention for the bus and device names is
operating-system dependent; AVRDUDE will print out what it found
on the bus when running it with (at least) one <var>-v</var> option.
By specifying a string that cannot match any existing device
(for example, <var>-P usb:xxx</var>), the scan will list all possible
candidate devices found on the bus.
</p>
<p>Examples:
</p><div class="example">
<pre class="example">avrdude -c usbtiny -p atmega8 -P usb:003:025 (Linux)
avrdude -c usbtiny -p atmega8 -P usb:/dev/usb:/dev/ugen1.3 (FreeBSD 8+)
avrdude -c usbtiny -p atmega8 \
-P usb:bus-0:\\.\libusb0-0001--0x1781-0x0c9f (Windows)
</pre></div>
</li><li>
Problem: I cannot do &hellip; when the target is in debugWire mode.
<p>Solution: debugWire mode imposes several limitations.
</p>
<p>The debugWire protocol is Atmel&rsquo;s proprietary one-wire (plus ground)
protocol to allow an in-circuit emulation of the smaller AVR devices,
using the <var>/RESET</var> line.
DebugWire mode is initiated by activating the <var>DWEN</var>
fuse, and then power-cycling the target.
While this mode is mainly intended for debugging/emulation, it
also offers limited programming capabilities.
Effectively, the only memory areas that can be read or programmed
in this mode are flash ROM and EEPROM.
It is also possible to read out the signature.
All other memory areas cannot be accessed.
There is no
<em>chip erase</em>
functionality in debugWire mode; instead, while reprogramming the
flash ROM, each flash ROM page is erased right before updating it.
This is done transparently by the JTAG ICE mkII (or AVR Dragon).
The only way back from debugWire mode is to initiate a special
sequence of commands to the JTAG ICE mkII (or AVR Dragon), so the
debugWire mode will be temporarily disabled, and the target can
be accessed using normal ISP programming.
This sequence is automatically initiated by using the JTAG ICE mkII
or AVR Dragon in ISP mode, when they detect that ISP mode cannot be
entered.
</p>
</li><li>
Problem: I want to use my JTAG ICE mkII to program an
Xmega device through PDI. The documentation tells me to use the
<em>XMEGA PDI adapter for JTAGICE mkII</em> that is supposed to ship
with the kit, yet I don&rsquo;t have it.
<p>Solution: Use the following pin mapping:
</p>
<table>
<tr><td width="20%"><strong>JTAGICE</strong></td><td width="20%"><strong>Target</strong></td><td width="20%"><strong>Squid cab-</strong></td><td width="20%"><strong>PDI</strong></td></tr>

</table>
</li><li>
Problem: I want to use my AVR Dragon to program an
Xmega device through PDI.
<p>Solution: Use the 6 pin ISP header on the Dragon and the following pin mapping:
</p>
<table>
<tr><td width="20%"><strong>Dragon</strong></td><td width="20%"><strong>Target</strong></td></tr>
<tr><td width="20%"><strong>ISP Header</strong></td><td width="20%"><strong>pins</strong></td></tr>
<tr><td width="20%">1 (MISO)</td><td width="20%">PDI_DATA</td></tr>
<tr><td width="20%">2 (VCC)</td><td width="20%">VCC</td></tr>
<tr><td width="20%">3 (SCK)</td><td width="20%"></td></tr>
<tr><td width="20%">4 (MOSI)</td><td width="20%"></td></tr>
<tr><td width="20%">5 (RESET)</td><td width="20%">PDI_CLK / RST</td></tr>
<tr><td width="20%">6 (GND)</td><td width="20%">GND</td></tr>
</table>
</li><li>
Problem: I want to use my AVRISP mkII to program an
ATtiny4/5/9/10 device through TPI. How to connect the pins?
<p>Solution: Use the following pin mapping:
</p>
<table>
<tr><td width="20%"><strong>AVRISP</strong></td><td width="20%"><strong>Target</strong></td><td width="20%"><strong>ATtiny</strong></td></tr>
<tr><td width="20%"><strong>connector</strong></td><td width="20%"><strong>pins</strong></td><td width="20%"><strong>pin #</strong></td></tr>
<tr><td width="20%">1 (MISO)</td><td width="20%">TPIDATA</td><td width="20%">1</td></tr>
<tr><td width="20%">2 (VTref)</td><td width="20%">Vcc</td><td width="20%">5</td></tr>
<tr><td width="20%">3 (SCK)</td><td width="20%">TPICLK</td><td width="20%">3</td></tr>
<tr><td width="20%">4 (MOSI)</td><td width="20%"></td><td width="20%"></td></tr>
<tr><td width="20%">5 (RESET)</td><td width="20%">/RESET</td><td width="20%">6</td></tr>
<tr><td width="20%">6 (GND)</td><td width="20%">GND</td><td width="20%">2</td></tr>
</table>
</li><li>
Problem: I want to program an ATtiny4/5/9/10 device using a serial/parallel
bitbang programmer. How to connect the pins?
<p>Solution: Since TPI has only 1 pin for bi-directional data transfer, both
<var>MISO</var> and <var>MOSI</var> pins should be connected to the <var>TPIDATA</var> pin
on the ATtiny device.
However, a 1K resistor should be placed between the <var>MOSI</var> and <var>TPIDATA</var>.
The <var>MISO</var> pin connects to <var>TPIDATA</var> directly.
The <var>SCK</var> pin is connected to <var>TPICLK</var>.
</p>
<p>In addition, the <var>Vcc</var>, <var>/RESET</var> and <var>GND</var> pins should
be connected to their respective ports on the ATtiny device.
</p>
</li><li>
Problem: How can I use a FTDI FT232R USB-to-Serial device for bitbang programming?
<p>Solution: When connecting the FT232 directly to the pins of the target Atmel device,
the polarity of the pins defined in the <code>programmer</code> definition should be
inverted by prefixing a tilde. For example, the <var>dasa</var> programmer would
look like this when connected via a FT232R device (notice the tildes in
front of pins 7, 4, 3 and 8):
</p>
<div class="example">
<pre class="example">programmer
id = &quot;dasa_ftdi&quot;;
desc = &quot;serial port banging, reset=rts sck=dtr mosi=txd miso=cts&quot;;
type = serbb;
reset = ~7;
sck = ~4;
mosi = ~3;
miso = ~8;
;
</pre></div>
<p>Note that this uses the FT232 device as a normal serial port, not using the
FTDI drivers in the special bitbang mode.
</p>
</li><li>
Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program
it (through TPI) fails. Instead, the memory retains the old contents.
<p>Solution: Mind the limited programming supply voltage range of these
devices.
</p>
<p>In-circuit programming through TPI is only guaranteed by the datasheet
at Vcc = 5 V.
</p>
</li><li>
Problem: My ATxmega&hellip;A1/A2/A3 cannot be programmed through PDI with
my AVR Dragon. Programming through a JTAG ICE mkII works though, as does
programming through JTAG.
<p>Solution: None by this time (2010 Q1).
</p>
<p>It is said that the AVR Dragon can only program devices from the A4
Xmega sub-family.
</p>
</li><li>
Problem: when programming with an AVRISPmkII or STK600, AVRDUDE hangs
when programming files of a certain size (e.g. 246 bytes). Other
(larger or smaller) sizes work though.
<p>Solution: This is a bug caused by an incorrect handling of zero-length
packets (ZLPs) in some versions of the libusb 0.1 API wrapper that ships
with libusb 1.x in certain Linux distributions. All Linux systems with
kernel versions &lt; 2.6.31 and libusb &gt;= 1.0.0 &lt; 1.0.3 are reported to be
affected by this.
</p>
<p>See also: <a href="http://www.libusb.org/ticket/6">http://www.libusb.org/ticket/6</a>
</p>
</li><li>
Problem: after flashing a firmware that reduces the target&rsquo;s clock
speed (e.g. through the <code>CLKPR</code> register), further ISP connection
attempts fail.
<p>Solution: Even though ISP starts with pulling <var>/RESET</var> low, the
target continues to run at the internal clock speed as defined by the
firmware running before. Therefore, the ISP clock speed must be
reduced appropriately (to less than 1/4 of the internal clock speed)
using the -B option before the ISP initialization sequence will
succeed.
</p>
<p>As that slows down the entire subsequent ISP session, it might make
sense to just issue a <em>chip erase</em> using the slow ISP clock
(option <code>-e</code>), and then start a new session at higher speed.
Option <code>-D</code> might be used there, to prevent another unneeded
erase cycle.

<p>The default location of the install is into <code>/usr/local</code> so you
will need to be sure that <code>/usr/local/bin</code> is in your <code>PATH</code>
environment variable.

following instead:

<h4 class="subsubsection">A.1.1.1 FreeBSD Installation</h4>
<p>AVRDUDE is installed via the FreeBSD Ports Tree as follows:
</p>
<div class="example">
<pre class="example">% su - root
# cd /usr/ports/devel/avrdude
# make install
</pre></div>
<p>If you wish to install from a pre-built package instead of the source,
you can use the following instead:
</p>
<div class="example">
<pre class="example">% su - root
# pkg_add -r avrdude
</pre></div>
<p>Of course, you must be connected to the Internet for these methods to
work, since that is where the source as well as the pre-built package is
obtained.

<h4 class="subsubsection">A.1.1.2 Linux Installation</h4>
<p>On rpm based Linux systems (such as RedHat, SUSE, Mandrake, etc.), you
can build and install the rpm binaries directly from the tarball:
</p>
<div class="example">
<pre class="example">$ su - root
# rpmbuild -tb avrdude-6.99-20211218.tar.gz
# rpm -Uvh /usr/src/redhat/RPMS/i386/avrdude-6.99-20211218-1.i386.rpm
</pre></div>
<p>Note that the path to the resulting rpm package, differs from system
to system. The above example is specific to RedHat.

<p>When AVRDUDE is build using the default &lsquo;<samp>--prefix</samp>&rsquo; configure
option, the default configuration file for a Unix system is located at
<code>/usr/local/etc/avrdude.conf</code>. This can be overridden by using the
&lsquo;<samp>-C</samp>&rsquo; command line option. Additionally, the user&rsquo;s home directory
is searched for a file named <code>.avrduderc</code>, and if found, is used to
augment the system default configuration file.

<a name="Installation"></a>
<h3 class="subsection">A.2.1 Installation</h3>
<p>A Windows executable of avrdude is included in WinAVR which can be found at
<a href="http://sourceforge.net/projects/winavr">http://sourceforge.net/projects/winavr</a>. WinAVR is a suite of executable,
open source software development tools for the AVR for the Windows platform.
</p>
<p>There are two options to build avrdude from source under Windows.
The first one is to use Cygwin (<a href="http://www.cygwin.com/">http://www.cygwin.com/</a>).
</p>
<p>To build and install from the source tarball for Windows (using Cygwin):
</p>
<div class="example">
<pre class="example">$ set PREFIX=&lt;your install directory path&gt;
$ export PREFIX
$ gunzip -c avrdude-6.99-20211218.tar.gz | tar xf -
$ cd avrdude-6.99-20211218
$ ./configure LDFLAGS=&quot;-static&quot; --prefix=$PREFIX --datadir=$PREFIX
--sysconfdir=$PREFIX/bin --enable-versioned-doc=no
$ make
$ make install
</pre></div>
<p>Note that recent versions of Cygwin (starting with 1.7) removed the
MinGW support from the compiler that is needed in order to build a
native Win32 API binary that does not require to install the Cygwin
library <code>cygwin1.dll</code> at run-time. Either try using an older
compiler version that still supports MinGW builds, or use MinGW
(<a href="http://www.mingw.org/">http://www.mingw.org/</a>) directly.

<h4 class="subsubsection">A.2.2.2 How AVRDUDE finds the configuration files.</h4>
<p>AVRDUDE on Windows has a different way of searching for the system and
user configuration files. Below is the search method for locating the
configuration files:
</p>
<ol>
<li>
Only for the system configuration file:
<code>&lt;directory from which application loaded&gt;/../etc/avrdude.conf</code>
</li><li>
The directory from which the application loaded.
</li><li>
The current directory.
</li><li>
The Windows system directory. On Windows NT, the name of this directory
is <code>SYSTEM32</code>.
</li><li>
Windows NT: The 16-bit Windows system directory. The name of this
directory is <code>SYSTEM</code>.
</li><li>
The Windows directory.
</li><li>
The directories that are listed in the PATH environment variable.

<h4 class="subsubsection">A.2.3.2 Parallel Ports</h4>
<p>AVRDUDE will accept 3 Windows parallel port names: lpt1, lpt2, or
lpt3. Each of these names corresponds to a fixed parallel port base
address:
</p>
<dl compact="compact">
<dt><code>lpt1</code></dt>
<dd><p>0x378
</p>
</dd>
<dt><code>lpt2</code></dt>
<dd><p>0x278
</p>
</dd>
<dt><code>lpt3</code></dt>
<dd><p>0x3BC
</p>
</dd>
</dl>
<p>On your desktop PC, lpt1 will be the most common choice. If you are
using a laptop, you might have to use lpt3 instead of lpt1. Select the
name of the port the corresponds to the base address of the parallel
port that you want.
</p>
<p>If the parallel port can be accessed through a different
address, this address can be specified directly, using the common C
language notation (i. e., hexadecimal values are prefixed by <code>0x</code>).

<p>In general, please report any bugs encountered via
<br>
<a href="https://github.com/avrdudes/avrdude/issues">https://github.com/avrdudes/avrdude/issues</a>.
</p>
<ul>
<li>
Problem: I&rsquo;m using a serial programmer under Windows and get the following
error:
<p><code>avrdude: serial_open(): can't set attributes for device &quot;com1&quot;</code>,
</p>
<p>Solution: This problem seems to appear with certain versions of Cygwin. Specifying
<code>&quot;/dev/com1&quot;</code> instead of <code>&quot;com1&quot;</code> should help.
</p>
</li><li>
Problem: I&rsquo;m using Linux and my AVR910 programmer is really slow.
<p>Solution (short): <code>setserial <var>port</var> low_latency</code>
</p>
<p>Solution (long):
There are two problems here. First, the system may wait some time before it
passes data from the serial port to the program. Under Linux the following
command works around this (you may need root privileges for this).
</p>
<p><code>setserial <var>port</var> low_latency</code>
</p>
<p>Secondly, the serial interface chip may delay the interrupt for some time.
This behaviour can be changed by setting the FIFO-threshold to one. Under Linux this
can only be done by changing the kernel source in <code>drivers/char/serial.c</code>.
Search the file for <code>UART_FCR_TRIGGER_8</code> and replace it with <code>UART_FCR_TRIGGER_1</code>. Note that overall performance might suffer if there
is high throughput on serial lines. Also note that you are modifying the kernel at
your own risk.
</p>
</li><li>
Problem: I&rsquo;m not using Linux and my AVR910 programmer is really slow.
<p>Solutions: The reasons for this are the same as above.
If you know how to work around this on your OS, please let us know.
</p>
</li><li>
Problem: Updating the flash ROM from terminal mode does not work with the
JTAG ICEs.
<p>Solution: None at this time. Currently, the JTAG ICE code cannot
write to the flash ROM one byte at a time.
</p>
</li><li>
Problem: Page-mode programming the EEPROM (using the -U option) does
not erase EEPROM cells before writing, and thus cannot overwrite any
previous value != 0xff.
<p>Solution: None. This is an inherent feature of the way JTAG EEPROM
programming works, and is documented that way in the Atmel AVR
datasheets.
In order to successfully program the EEPROM that way, a prior chip
erase (with the EESAVE fuse unprogrammed) is required.
This also applies to the STK500 and STK600 in high-voltage programming mode.
</p>
</li><li>
Problem: How do I turn off the <var>DWEN</var> fuse?
<p>Solution: If the <var>DWEN</var> (debugWire enable) fuse is activated,
the <var>/RESET</var> pin is not functional anymore, so normal ISP
communication cannot be established.
There are two options to deactivate that fuse again: high-voltage
programming, or getting the JTAG ICE mkII talk debugWire, and
prepare the target AVR to accept normal ISP communication again.
</p>
<p>The first option requires a programmer that is capable of high-voltage
programming (either serial or parallel, depending on the AVR device),
for example the STK500. In high-voltage programming mode, the
<var>/RESET</var> pin is activated initially using a 12 V pulse (thus the
name <em>high voltage</em>), so the target AVR can subsequently be
reprogrammed, and the <var>DWEN</var> fuse can be cleared. Typically, this
operation cannot be performed while the AVR is located in the target
circuit though.
</p>
<p>The second option requires a JTAG ICE mkII that can talk the debugWire
protocol. The ICE needs to be connected to the target using the
JTAG-to-ISP adapter, so the JTAG ICE mkII can be used as a debugWire
initiator as well as an ISP programmer. AVRDUDE will then be activated
using the <var>jtag2isp</var> programmer type. The initial ISP
communication attempt will fail, but AVRDUDE then tries to initiate a
debugWire reset. When successful, this will leave the target AVR in a
state where it can accept standard ISP communication. The ICE is then
signed off (which will make it signing off from the USB as well), so
AVRDUDE has to be called again afterwards. This time, standard ISP
communication can work, so the <var>DWEN</var> fuse can be cleared.
</p>
<p>The pin mapping for the JTAG-to-ISP adapter is:
</p>
<table>
<tr><td width="20%"><strong>JTAG pin</strong></td><td width="20%"><strong>ISP pin</strong></td></tr>
<tr><td width="20%">1</td><td width="20%">3</td></tr>
<tr><td width="20%">2</td><td width="20%">6</td></tr>
<tr><td width="20%">3</td><td width="20%">1</td></tr>
<tr><td width="20%">4</td><td width="20%">2</td></tr>
<tr><td width="20%">6</td><td width="20%">5</td></tr>
<tr><td width="20%">9</td><td width="20%">4</td></tr>
</table>
</li><li>
Problem: Multiple USBasp or USBtinyISP programmers connected simultaneously are not
found.
<p>Solution: The USBtinyISP code supports distinguishing multiple
programmers based on their bus:device connection tuple that describes
their place in the USB hierarchy on a specific host. This tuple can
be added to the <var>-P usb</var> option, similar to adding a serial number
on other USB-based programmers.
</p>
<p>The actual naming convention for the bus and device names is
operating-system dependent; AVRDUDE will print out what it found
on the bus when running it with (at least) one <var>-v</var> option.
By specifying a string that cannot match any existing device
(for example, <var>-P usb:xxx</var>), the scan will list all possible
candidate devices found on the bus.
</p>
<p>Examples:
</p><div class="example">
<pre class="example">avrdude -c usbtiny -p atmega8 -P usb:003:025 (Linux)
avrdude -c usbtiny -p atmega8 -P usb:/dev/usb:/dev/ugen1.3 (FreeBSD 8+)
avrdude -c usbtiny -p atmega8 \
-P usb:bus-0:\\.\libusb0-0001--0x1781-0x0c9f (Windows)
</pre></div>
</li><li>
Problem: I cannot do &hellip; when the target is in debugWire mode.
<p>Solution: debugWire mode imposes several limitations.
</p>
<p>The debugWire protocol is Atmel&rsquo;s proprietary one-wire (plus ground)
protocol to allow an in-circuit emulation of the smaller AVR devices,
using the <var>/RESET</var> line.
DebugWire mode is initiated by activating the <var>DWEN</var>
fuse, and then power-cycling the target.
While this mode is mainly intended for debugging/emulation, it
also offers limited programming capabilities.
Effectively, the only memory areas that can be read or programmed
in this mode are flash ROM and EEPROM.
It is also possible to read out the signature.
All other memory areas cannot be accessed.
There is no
<em>chip erase</em>
functionality in debugWire mode; instead, while reprogramming the
flash ROM, each flash ROM page is erased right before updating it.
This is done transparently by the JTAG ICE mkII (or AVR Dragon).
The only way back from debugWire mode is to initiate a special
sequence of commands to the JTAG ICE mkII (or AVR Dragon), so the
debugWire mode will be temporarily disabled, and the target can
be accessed using normal ISP programming.
This sequence is automatically initiated by using the JTAG ICE mkII
or AVR Dragon in ISP mode, when they detect that ISP mode cannot be
entered.
</p>
</li><li>
Problem: I want to use my JTAG ICE mkII to program an
Xmega device through PDI. The documentation tells me to use the
<em>XMEGA PDI adapter for JTAGICE mkII</em> that is supposed to ship
with the kit, yet I don&rsquo;t have it.
<p>Solution: Use the following pin mapping:
</p>
<table>
<tr><td width="20%"><strong>JTAGICE</strong></td><td width="20%"><strong>Target</strong></td><td width="20%"><strong>Squid cab-</strong></td><td width="20%"><strong>PDI</strong></td></tr>
<tr><td width="20%"><strong>mkII probe</strong></td><td width="20%"><strong>pins</strong></td><td width="20%"><strong>le colors</strong></td><td width="20%"><strong>header</strong></td></tr>
<tr><td width="20%">1 (TCK)</td><td width="20%"></td><td width="20%">Black</td><td width="20%"></td></tr>
<tr><td width="20%">2 (GND)</td><td width="20%">GND</td><td width="20%">White</td><td width="20%">6</td></tr>
<tr><td width="20%">3 (TDO)</td><td width="20%"></td><td width="20%">Grey</td><td width="20%"></td></tr>

</li><li>
Problem: I want to use my AVR Dragon to program an

<tr><td width="20%"><strong>ISP Header</strong></td><td width="20%"><strong>pins</strong></td></tr>
<tr><td width="20%">1 (MISO)</td><td width="20%">PDI_DATA</td></tr>

Problem: I want to use my AVRISP mkII to program an
ATtiny4/5/9/10 device through TPI. How to connect the pins?
<p>Solution: Use the following pin mapping:
</p>
<table>
<tr><td width="20%"><strong>AVRISP</strong></td><td width="20%"><strong>Target</strong></td><td width="20%"><strong>ATtiny</strong></td></tr>
<tr><td width="20%"><strong>connector</strong></td><td width="20%"><strong>pins</strong></td><td width="20%"><strong>pin #</strong></td></tr>
<tr><td width="20%">1 (MISO)</td><td width="20%">TPIDATA</td><td width="20%">1</td></tr>
<tr><td width="20%">2 (VTref)</td><td width="20%">Vcc</td><td width="20%">5</td></tr>
<tr><td width="20%">3 (SCK)</td><td width="20%">TPICLK</td><td width="20%">3</td></tr>
<tr><td width="20%">4 (MOSI)</td><td width="20%"></td><td width="20%"></td></tr>
<tr><td width="20%">5 (RESET)</td><td width="20%">/RESET</td><td width="20%">6</td></tr>
<tr><td width="20%">6 (GND)</td><td width="20%">GND</td><td width="20%">2</td></tr>

Problem: I want to program an ATtiny4/5/9/10 device using a serial/parallel
bitbang programmer. How to connect the pins?
<p>Solution: Since TPI has only 1 pin for bi-directional data transfer, both
<var>MISO</var> and <var>MOSI</var> pins should be connected to the <var>TPIDATA</var> pin
on the ATtiny device.
However, a 1K resistor should be placed between the <var>MOSI</var> and <var>TPIDATA</var>.
The <var>MISO</var> pin connects to <var>TPIDATA</var> directly.
The <var>SCK</var> pin is connected to <var>TPICLK</var>.
</p>
<p>In addition, the <var>Vcc</var>, <var>/RESET</var> and <var>GND</var> pins should
be connected to their respective ports on the ATtiny device.
</p>
</li><li>
Problem: How can I use a FTDI FT232R USB-to-Serial device for bitbang programming?
<p>Solution: When connecting the FT232 directly to the pins of the target Atmel device,
the polarity of the pins defined in the <code>programmer</code> definition should be
inverted by prefixing a tilde. For example, the <var>dasa</var> programmer would
look like this when connected via a FT232R device (notice the tildes in
front of pins 7, 4, 3 and 8):
</p>
<div class="example">
<pre class="example">programmer
id = &quot;dasa_ftdi&quot;;
desc = &quot;serial port banging, reset=rts sck=dtr mosi=txd miso=cts&quot;;
type = serbb;
reset = ~7;
sck = ~4;
mosi = ~3;
miso = ~8;
;
</pre></div>
<p>Note that this uses the FT232 device as a normal serial port, not using the
FTDI drivers in the special bitbang mode.
</p>
</li><li>
Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program
it (through TPI) fails. Instead, the memory retains the old contents.
<p>Solution: Mind the limited programming supply voltage range of these
devices.
</p>
<p>In-circuit programming through TPI is only guaranteed by the datasheet
at Vcc = 5 V.
</p>
</li><li>
Problem: My ATxmega&hellip;A1/A2/A3 cannot be programmed through PDI with
my AVR Dragon. Programming through a JTAG ICE mkII works though, as does
programming through JTAG.
<p>Solution: None by this time (2010 Q1).
</p>
<p>It is said that the AVR Dragon can only program devices from the A4
Xmega sub-family.
</p>
</li><li>
Problem: when programming with an AVRISPmkII or STK600, AVRDUDE hangs
when programming files of a certain size (e.g. 246 bytes). Other
(larger or smaller) sizes work though.
<p>Solution: This is a bug caused by an incorrect handling of zero-length
packets (ZLPs) in some versions of the libusb 0.1 API wrapper that ships
with libusb 1.x in certain Linux distributions. All Linux systems with
kernel versions &lt; 2.6.31 and libusb &gt;= 1.0.0 &lt; 1.0.3 are reported to be
affected by this.
</p>
<p>See also: <a href="http://www.libusb.org/ticket/6">http://www.libusb.org/ticket/6</a>
</p>
</li><li>
Problem: after flashing a firmware that reduces the target&rsquo;s clock
speed (e.g. through the <code>CLKPR</code> register), further ISP connection
attempts fail.
<p>Solution: Even though ISP starts with pulling <var>/RESET</var> low, the
target continues to run at the internal clock speed as defined by the
firmware running before. Therefore, the ISP clock speed must be
reduced appropriately (to less than 1/4 of the internal clock speed)
using the -B option before the ISP initialization sequence will
succeed.
</p>
<p>As that slows down the entire subsequent ISP session, it might make
sense to just issue a <em>chip erase</em> using the slow ISP clock
(option <code>-e</code>), and then start a new session at higher speed.
Option <code>-D</code> might be used there, to prevent another unneeded
erase cycle.
</p>
