I resolved the problem with bossac in Eclipse , for some reasons ,in my case , if as first parameter in the arguments list is placed --port=tty.usbmodemfd121 the command ends with :
No device found on tty.usbmodemfd121 also when I press the erase button.
if --port is used as seconds parameter, using the erase button, eclipse and bossac run like a charm.

CPU reset.
I tried to open the programming port and then to launch bossac , but I have still the uploading problem.
For the moment it works fine with the erase button.
@joppuh123:
It seems your core library doesn't contain wiring_digital.c , do you have it in yours library files? it is contained inside variants/arduino_due_x
