Due to the growing interest in porting the software to other operating systems, Brian decided to make the project publically accessible on savannah. In , the project moved from Savannah to Github to benefit from the tooling that eventually evolved around the Git version control system. People who want to contribute in some way to the project can subscribe to the avrdude-dev mailing list , and get in contact with the developer team there.

There is a Developers\’ Corner with some random articles. Some more information is available at Brian\’s private site.

AVRDUDE can be used eectively via the command line to read or write all chip memory types eeprom, ash, fuse bits, lock bits, signature bytes or via an interactive terminal mode. PPI represents a class of simple programmers where the programming lines are directly connected to the PC parallel port.

Several pin congurations exist for several variations of the PPI programmers, and AVRDUDE can be be congured to work with them by either specifying the appropriate programmer on the command line or by creating a new entry in its conguration le.

A number of equally simple bit-bang programming adapters that connect to a serial port are supported as well, among them the popular Ponyprog serial adapter, and the DASA and DASA3 adapters that used to be supported by uisp 1. Note that these adapters are meant to be attached to a physical serial port. Connecting to a serial port emulated on top of USB is likely to not work at all, or to work abysmally slow.

Of course, care should be taken about voltage level compatibility. Also, although not strictrly required, it is strongly advisable to protect the GPIO pins from overcurrent situations in some way. The simplest would be to just put some resistors in series or better yet use a 3-state buer driver like the 74HC Bit 1 the lsb of the byte in the cong le is SCK.

Bit 4 usually reset. The avr bootloader implements a protocol similar to avr, but is actually implemented in the boot area of the targets ash ROM, as opposed to being an external device. The fundamental dierence between the two types lies in the protocol used to control the programmer. The avr protocol is very simplistic and can easily be used as the basis for a simple, home made programmer since the rmware is available online.

On the other hand, the STK protocol is more robust and complicated and the rmware is not openly available. See below for the limitations of debugWire. In particular, the Dragon starts out with a rather fast ISP clock frequency, so the -B bitclock option might be required to achieve a stable ISP communication. Wiring boards are supported, utilizing STK V2. The programmer type is wiring. The Arduino which is very similar to the STK 1. See the section on extended parameters below for details.

EXE which is the name of Atmels Windows programming software. And in the spirit of many open source projects, this manual also draws on the work of others. The texi formatting was modeled after that of the Simulavr documentation by Ted Roth.

The partno parameter is the parts id listed in the conguration le. Specify -p? If a part is unknown to AVRDUDE, it means that there is no cong le entry for that part, but it can be added to the conguration le if you have the Atmel datasheet so that you can enter the programming specications. Known to work are jtag2, stkv2, and bit-bang programmers. Thus, not all programmers support this device.

Known to work are all direct bitbang programmers, and all programmers talking the STKv2 protocol. The value is a oating-point number in microseconds. It can also be set in the conguration le by using the default bitclock keyword. Use this option to specify which one to use. The programmer-id parameter is the programmers id listed in the conguration le. Specify -c? Simply copy an existing entry and change the pin denitions to match that of the unknown programmer.

If you have a programmer or part that AVRDUDE does not know about, you can add it to the cong le be sure and submit a patch back to the author so that it can be incorporated for the next version. See Appendix A for the method of searching for the conguration le for Windows. This can be used to add entries to the conguration without patching your system wide conguration le.

It can be used several times, the les are read in same order as given on the command line. When the -U option with ash memory is specied, avrdude will perform a chip erase before starting any of the programming operations, since it generally is a mistake to program the ash without performing an erase rst. This option disables that.

Auto erase is not used for ATxmega devices as these devices can use page erase before writing each page so no explicit chip erase is required. Note however that any page not aected by the current operation will retain its previous contents. Causes a chip erase to be executed. Except for ATxmega devices which can use page erase, it is basically a prerequisite command before the ash ROM can be reprogrammed again.

The only exception would be if the. Note that in order to reprogram EERPOM cells, no explicit prior chip erase is required since the MCU provides an auto-erase cycle in that case before programming the cell. This option will leave those parallel port pins active i.

This option will pull the Vcc pins of the parallel port down at program exit. This option will leave the 8 data pins on the parallel port active i.

This option will leave the 8 data pins on the parallel port inactive i. Multiple exitspec arguments can be separated with commas. Since it can happen from time to time that a device has a broken erased or overwritten device signature but is otherwise operating normally, this options is provided to override the check.

Also, for programmers like the Atmel STK and STK which can adjust parameters local to the programming tool independent of an actual connection to a target controller , this option can be used together with -t to continue in terminal mode. For bitbang-type programmers, delay for approximately delay microseconds between each bit state change. This is implemented. On Unix-style operating systems, the spin loop is initially calibrated against a system timer, so the number of microseconds might be rather realistic, assuming a constant system load while AVRDUDE is running.

On Win32 operating systems, a precongured number of cycles per microsecond is assumed that might be o a bit for very fast or very slow machines.

Note that initial diagnostic messages during option parsing are still written to stderr anyway. Use port to identify the device to which the programmer is attached. Normally, the default parallel port is used, but if the programmer type normally connects to the serial port, the default serial port will be used. If you need to use a dierent parallel or serial port, use this option to specify the alternate port name. On Win32 operating systems, the parallel ports are referred to as lpt1 through lpt3, referring to the addresses 0x, 0x, and 0x3BC, respectively.

If the parallel port can be accessed through a dierent address, this address can be specied directly, using the common C language notation i. The match is done after stripping any existing colons from the given serial number, and right-to-left, so only the least signicant bytes from the serial number need to be given. Libusb support is required on Unix but not on Windows. See Appendix B [Troubleshooting], page 42, for examples.

For programmers that attach to a serial port using some kind of higher level protocol as opposed to bit-bang style programmers , port can be specied as net:host:port. The remote endpoint is assumed to be a terminal or console server that connects the network stream to a local serial port where the actual programmer has been attached to.

The port is assumed to be properly congured, for example using a transparent 8-bit data connection without parity at Baud for a STK This feature is currently not implemented for Win32 systems.

Specify it a second time for even quieter operation. Disables the default behaviour of reading out the fuses three times before programming, then verifying at the end of programming that the fuses have not changed.

If you want to change fuses you will need to specify this option, as avrdude will see the fuses have changed even though you wanted to and will change them back for your \”safety\”. This option was designed to prevent cases of fuse bits magically changing usually called safemode. The -u options eect is negated in that case, i. Disable safemode prompting.

When safemode discovers that one or more fuse bits have unintentionally changed, it will prompt for conrmation regarding whether or not it should attempt to recover the fuse bit s. Specifying this ag disables the prompt and assumes that the fuse bit s should be recovered without asking for conrmation rst. See below for a detailed description of the terminal mode. Multiple -U options can be specied in order to operate on multiple memories on the same command-line invocation.

The memtype eld species the memory type to operate on. Use the -v option on the command line or the part command from terminal mode to display all the memory types supported by a particular device.

Typically, a devices memory conguration at least contains the memory types flash and eeprom. All memory types currently known are: calibration One or more bytes of RC oscillator calibration data. The extended fuse byte. The ash ROM of the device. The fuse byte in devices that have only a single fuse byte. The high fuse byte. The low fuse byte. The lock byte. The three device signature bytes device ID. The boot ash area of ATxmega devices. The production signature calibration area of ATxmega devices.

The user signature area of ATxmega devices. The op eld species what operation to perform: r w v read the specied device memory and write to the specied le read the specied le and write it to the specied device memory read the specied device memory and the specied le and perform a verify operation.

Useful to record debugging traces, in particular in environments which do not offer shell-style redirection functionality for standard streams. Verbatim copying and distribution of this entire article is permitted in any medium, provided this notice is preserved.
