Can't programm MKR Fox 1200

Official Hardware MKR Family MKR FOX 1200
1

Hello,

Everytime I try to programm the MKR Fox 1200 Board with the Arduino IDE, I get the error: "No device found on COM8".
The device is correctly recognized by Windows 7. I can see it in the device manager and in the Arduino IDE.

The last Sketch I programmed was the example for the 'ArduinoLowPower' lib. The board is going very fast into sleep mode. Until this sketch, I had that error sometimes, but after reconnecting it to the computer it worked again.

I tried to push the reset button while uploading. I also tried to reboot the computer and plugging it into other usb ports. Nothing worked.

Is there some kind of erase feature?

This is the Output of the Arduino IDE:

Sketch uses 29608 bytes (11%) of program storage space. Maximum is 262144 bytes.

Did you try the "quickly double tap the reset button" to put it into bootloader mode on a fixed com port ?

Works for all the MKR series boards and then allows you to upload on the bootloader port.
I always suggest a simple sketch at that point such as BLINK or BAREMINIMUM from the examples.

Thanks, that worked!
