The avrdude man page indicates that debugWire doesn't support an
explicit flash erase command, but that the erase is handled implicity
by the JTAG ICE mkII during a write operation. debugWire is working
well, but the erasing part of the programming doesn't seem to be
working.
avrdude 5.3.1
JTAG ICE mkII

Thanks,
