Hi, I am david , and I am new to Arduino. I got a Arduino Zero (M0 Pro R3). Tried to load a test program to the board and failed. I followed the procedure about "Uploading trouble shooting" very carefully, and the problem did not go away. Your help is much appreciated. Thanks.
Here are the message returned by IDE:
