avrdude - Adding the AVR Dragon's HVPP to the Arduino IDE

I would like to teach my Arduino IDE to use my AVR Dragon's HVPP (High Voltage Parallel Programming) interface to upload compiled sketches to my boards (an ATMega1284P-PU in this case, supported by mighty1284p).

Working setup so far:

Arduino IDE with mighty1284p, I added this to the boards.txt of mighty1284p to support my uC's internal-RC-oscillator clockrates of 1MHz and 8MHz.

avrdude can talk to the m1284p and set the fuses:

avrdude -c dragon_pp -P usb -p m1284p -U lfuse:w:0x62:m -U hfuse:w:0x99:m -U efuse:w:0xFF:m -U lock:w:0xFF:m

I can compile / check a sketch successfully, then upload the temporarily created .hex manually to the 1284 using the Dragon:

cd /var/folders/px/xmf1dygn6p5_fn1hh05c6gyr0000gn/T/build4082512148637729777.tmp/
avrdude -p m1284p -c dragon_pp -P usb -U flash:w:Fade.cpp.hex

This works but includes the manual step of cding into the temporary build directory and manually uplading the .hex.

How would I use the AVR Dragon's HVPP directly from within the Arduino IDE? I have added a section to programmers.txt as such:

dragonpp.name=AVR Dragon HVPP
dragonpp.communication=usb
dragonpp.protocol=dragon_pp
dragonpp.force=false

which I assumed would be correct for the above avrdude parameters.

Within the IDE I choose Tools - Programmer - AVR Dragon HVPP, the Upload. The debug output shows this:

(...correct compiling, linking and such...)

avrdude done.  Thank you.

So the -p parameter is correct, but -c and -P are wrong.

Any ideas how I could add the Dragon correctly?

Answer

Your problem is that the programmer settings in your part entry (shown in your other question) override the programmer settings in the programmer entry.

Just lose these lines in the part entries:

mighty_opt8.upload.protocol=arduino
