Follow-up Comment #1:
It's not a bug, it's a feature: your flash is empty (erased),
thus the resulting file is empty, too. You have chosen raw
file output, so you get a file with length 0. If you had
chosen e.g. Intel hex output, you'd at least get the terminal
record in the file – as an indication that everything worked
well, but there simple are no data to display.
Without that feature, readout of a partially filled flash
would always get a bunch of 0xFFFF values at the end of the
file. The feature is only applied to flash, not to EEPROM,
that's why your EEPROM readout indeed yields a file full of
0xFF. Yes, that's not really quite consistent, but has been
that way since the early days of AVRDUDE.
