guide to dfu programing using a usbtiny to a atmega32u2
1. download newest winavr and install
2. modify avrdude.conf in the bin directory under AT90USB162
from this:
memory "flash"
paged = yes;
size = 16384;
page_size = 128;
num_pages = 128;
into this:
memory "flash"
paged = yes;
size = 32768;
page_size = 128;
num_pages = 256;
i also changed
desc = "atmega32u2";
update your makefile to point to the correct programing device.
fix this
AVRDUDE_PROGRAMMER = usbtiny
AVRDUDE_PORT = usb
now run
make
make program.
i used a usbtiny from sparkfun.
or manualy
avrdude -p atmega32u2 -F -P usb -c usbtiny -v -U flash:w:Arduino-usbdfu.hex -U efuse:w:0xF4:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m -U lock:w:0x0F:m
