I have two Arduino Due boards with some programming that has since been lost. I need to back up the contents before replacing the program. I’ve been playing around with another Arduino Due before I move to taking the precious program off of the boards in question.

I have BOSSAC running on Mac OS X 10.7.5 (Lion), but am having trouble connecting to the chip and getting the binary file. I’ve tried:

bossac -p /dev/cu.usbmodem* -r adlights.bin`

But it hasn’t gotten me anywhere. I had read that I need to change the baud rate to 1200, but using the following command has not done the trick for me:

stty -f /dev/cu.usbmodem* 1200

  • Not 100% familiar with this process, but from [what I am reading here](http://forum.arduino.cc/index.php?topic=142550.0), there seems to be a verbose mode in BOSSAC? Posting that as debugging info should help shed more light on what might be choking things. – Giacomo1968 Sep 02 '15 at 23:17
