i try to get the SAM C21 Xplained Pro programmed with the Atmel ICE Basic. Double Checked the PIN Connection already. It leads always to the Error 4109 No Device detected. Does someone has any idea where the problem could be? Atmel Studio detects both C21 and ICE but i'm not able to program. Thank you very much for any help.
