Failure to upload sketch to MKR1000

Dear Sir,

I fail to upload sketch to MKR1000, the error message is as follows:

Arduino: 1.8.12 (Windows 10), Board: "Arduino MKR1000"

Sketch uses 30280 bytes (11%) of program storage space. Maximum is 262144 bytes.
Global variables use 5828 bytes of dynamic memory.

An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

May I have your suggestions?
Many thanks.

  • If you cannot select the port, please click "upload" anyway and once you see in the console a text like the following one, please give quick double tap to the reset button:

PORTS {COM131, } / {COM131, } => {}
PORTS {COM131, } / {COM131, } => {}
PORTS {COM131, } / {COM131, } => {}

  • Ca you see the ports under device manager once you click the reset button twice
  • Does the double tap show the fading behaviour of LED?

Hi, racpra16. I have solved the problem by using your method. Thanks a lot.
