Tried it a couple of times and it comes up with the same error.
Chilipeppr > Programming… Could not program the board.
SPJS > error: signal: illegal instruction

I pulled the Due out brought it to my office and I was able to flash it directly with the method I used in the past.

Hmm. Is that a Pi 1 or Pi 2 you were trying to program your board from?

Tested from both a RPi B+ & RPi 2.

I was able to get it to work via the RPi B+. Seems like whatever you have in the bin/bossac folder will not work on RPi or BBB. I had to use another one and replace the one you provided. (Which took upgrading from wheezy to jesse and downing and recompiling the Arduino IDE (1.6.5)

Oh you may want to put in some kind of verbiage to disconnect CP from the port your are trying to flash or have some kind of logic that disconnects the the port when you enter the flash ‘widget’

Yes, that was a detail I missed. I’m so trained to disconnect I forgot I need to force folks or do it automatically for them.
