    _______________________________________________________

Details:

The 'A' command must send the address in word offset, it is currently sent in
byte offset.

For instance with a 128 bytes buffer, avrdude send:

A 00 00
A 00 80
A 01 00
A 01 80
etc

each command followed by 128 bytes of data.

This is wrong, the correct offset is:

A 00 00
A 00 40
A 00 80
A 00 C0
etc

for flash data you have to >>1 the address before sending it with 'A' command.
