Best,
I use Atmel studio, Atmel Ice and an adafruit feather M0.
Via Atmel Ice I can make a connection via SWD, device programming, so this connection works.
But when I select the Atmel SAM-Ice in 'micro programmer toolbar options', click 'Enable Programmer' and then click 'build and upload' I get the following error:
Compiling 'Blink' for 'Adafruit Feather M0'
Program size: 10.624 bytes (used 4% of a 262.144 byte maximum) (0,47 secs)
Uploading 'Blink' to 'Adafruit Feather M0' using 'sam_ice'

The upload process has finished.

What could be the problem?
