I'm using lots of Uno's in my designs, but I'm having a real tough time getting the Due to upload a sketch.
I purchased one Due locally here in Toronto, and I noticed the "L" light was not blinking when I first powered on, although the Windows Device Manager reported "Arduino Due Programming Port" on Com 9.
Arduino IDE found the board and I selected Com 9. Reading Board Info showed "Unknown".
Long story sorry.... I used board manager and uploaded the core. Still the Due would hang when uploading a sketch.
I replaced the board with a second Due ( same local source) and the L light was flashing, and the Board Info now shows "Arduino Due". The Board manager reports the core as installed.
But the IDE hangs when uploading a Blink sketch to this board as well. I held down the "Erase" button and tried resetting the board, but always the IDE hangs during an upload.
Do I just have 2 bad boards? Any suggestions much appreciated!!!!
