I try to use AVRDude to program mega48 in debugWire mode on Windows machine. It does not work.
The command line looks like
avrdude -pm48 -cdragon_dw -Uflash:w:GPI.hex:a
The error is:
avrdude: ser_open(): can't open device "lpt1": The system cannot find the file specified.
avrdude from winavr 2100110. I do not understand why avrdude is trying to open lpt1? What port have to be specified to get it working?
