    _______________________________________________________

Details:

When avrdude is offered an input file for programming that contains a block
of 0xff bytes (as in the attached sample file, which contains a flash based
data table, all 0xff bytes), it only send that flash memory up to the 0xff
data to the programmer.

There seems to be an assumption that there cannot be a block of 0xff data in
the flash.

In general, avrdude seems to map input data into a flat memory space, losing
information of which blocks were in the input file and which were not. This
make proper verification also kind of impossible.
