I read on this forum a few confused posts about using AVR Dragon as an external programmer with Arduino IDE and thought my experience may be useful to someone.<\/p>\n

AVR Dragon can be used as an external programmer with Arduino IDE, e.g. to burn sketches to Arduino-compatible hardware without the bootloader. For example, I use it to upload my sketch to an ATMega8L controlling an audio amplifier based on TI’s TAS5086 PWM processor. I use it under Mac OS X; I have heard, but not tested, that the same thing under Windows may be tricky because of USB driver incompatibility.
\n
\nAs expained in http:\/\/www.arduino.cc\/en\/Hacking\/Programmer<\/a>, I add the following three lines to the programmers.txt:<\/p>\n

dragon.name=Atmel AVR Dragon in ISP mode
\ndragon.communication=usb
\ndragon.protocol=dragon_isp<\/p>\n

(after that, AVR Dragon appears in the list of programmers in the «Tools -> Burn Bootloader» menu), and either change the line<\/p>\n

upload.using=bootloader<\/p>\n

in the preferences.txt (which must be edited when the IDE is not running, or it will be overwritten) to<\/p>\n

upload.using=dragon<\/p>\n

to have Arduino IDE use AVR Dragon for all uploads, or add the line<\/p>\n

atmega328.upload.using=dragon<\/p>\n

to the appropriate section of boards.txt to use AVR Dragon only if «Arduino Duemilanove or Nano w\/ ATmega32» is selected.<\/p>\n

Either way, when I connect my Arduino Duemilanove to the AVR Dragon with an ISP cable, Arduino IDE uploads sketches flawlessly.<\/p>\n

For some reason, I cannot burn the bootloader in the same way. avrdude sucessfully writes unlock bits with the following command:<\/p>\n

\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/tools\/avr\/bin\/avrdude -C\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/tools\/avr\/etc\/avrdude.conf -v -v -v -v -patmega328p -cdragon_isp -Pusb -e -Ulock:w:0x3F:m -Uefuse:w:0x05:m -Uhfuse:w:0xDA:m -Ulfuse:w:0xFF:m<\/p>\n

but the attempt to actually burn the bootloader fails:<\/p>\n

\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/tools\/avr\/bin\/avrdude -C\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/tools\/avr\/etc\/avrdude.conf -v -v -v -v -patmega328p -cdragon_isp -Pusb -Uflash:w:\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/arduino\/bootloaders\/atmega\/ATmegaBOOT_168_atmega328.hex:i -Ulock:w:0x0F:m<\/p>\n

System wide configuration file is «\/Applications\/Arduino.app\/Contents\/Resources\/Java\/hardware\/tools\/avr\/etc\/avrdude.conf»
\nUser configuration file is «\/Users\/*******\/.avrduderc»
\nUser configuration file does not exist or is not a regular file, skipping<\/p>\n

Using Port\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 : usb
\nUsing Programmer\u00a0 \u00a0 \u00a0 : dragon_isp
\navrdude: stk500v2_dragon_isp_open()
\navrdude: usbdev_open(): did not find any USB device «usb»<\/p>\n

If I copy-paste that last command into the terminal, it works just fine. I’d be grateful is someone let me know how to make it work from within the IDE.<\/p>\n","protected":false},"excerpt":{"rendered":"
