Windows 10 x64
Currently using Arduino IDE vers. 1.8.3, tried earlier versions also.
Device manager shows "Arduino Due Programming Port (COM7)
IDE: Board->Arduino Duemilanove or Diecimilia
Processor->ATmega328
Port->COM7 (Arduino Due (Programming Port))
(lower right status bar reflects the same info)
Get Board info returns BN: Arduino Due (Programming Port)
VID: 2A03
PID: 003D
SN: 55639...(you get the point)
(Also ran the loopback test referred to elsewhere in the forum - checks fine)
Compile/Verify - no errors, just the standard info...
Arduino: 1.8.3 (Windows 10), Board: "Arduino Duemilanove or Diecimila, ATmega328"
Sketch uses 928 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
Upload, on the other hand...

That way I could tell if the sketch overwrote the 'blinker' that was loaded at the factory)

Both Mega2560s upload just fine after I switch the board & port selection.
Googled around and see a lot of references to "bossac" for uploading .bin files, was wondering where the avrdude stuff showed up? I did notice that avrdude works with .hex files...
Did I miss some installation step? IDE did notify me about Due drivers and I installed them.
Someone point me to the right info I need to read please?
