3. firmware is available online On the other hand the STK500 protocol is more robust and complicated and the firmware is not openly available The JTAG ICE also uses a serial communication protocol which is similar to the STK500 firmware version 2 one However as the JTAG ICE is intented to allow on chip debugging as well as memory programming the protocol is more sophisticated The JTAG ICE mkII protocol can also be run on top of USB Only the memory programming functionality of the J TAG ICE is supported by AVRDUDE 1 1 History and Credits AVRDUDE was written by Brian S Dean under the name of AVRPROG to run on the FreeBSD Operating System Brian renamed the software to be called AVRDUDE when interest grew in a Windows port of the software so that the name did not conflict with AVRPROG EXE which is the name of Atmel s Windows programming software Chapter 1 Introduction 2 The AVRDUDE source now resides in the public CVS repository on savannah gnu org http savannah gnu org projects avrdude where it continues to be enhanced and ported to other systems In addition to FreeBSD AVRDUDE now runs on Linux and Win dows The developers behind the porting effort primarily were Ted Roth Eric Weddington and Joerg Wunsch And in the spirit of many open source projects this manual also draws on the work of others The initial revision was composed of parts of the original Unix manual page written by Joerg Wunsch the original web site docume

5. simple programmers where the programming lines are directly connected to the PC parallel port Several pin configurations exist for several variations of the PPI programmers and AVRDUDE can be be configured to work with them by either specifying the appropriate programmer on the command line or by creating a new entry in its configuration file All that s usually required for a new entry is to tell AVRDUDE which pins to use for each programming function 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 The STK500 JTAG ICE avr910 and avr109 butterfly use the serial port to communi cate with the PC The STK500 JTAG ICE and avr910 contain on board logic to control the programming of the target device The avr109 bootloader implements a protocol sim ilar to avr910 but is actually implemented in the boot area of the target s flash ROM as opposed to being an external device The fundamental difference between the two types lies in the protocol used to control the programmer The avr910 protocol is very simplistic and can easily be used as the basis for a simple home made programer since the
