Cannot upload sketch on Arduino Giga R1 WiFi

Official Hardware Mega GIGA R1 WiFi
2

Hello manne_ef,

I have the exact same problem as you !

I also tried :

  • Connecting the Arduino GIGA R1 to another PC. I have the same "exit status 74" problem.
  • Using another board (Arduino UNO R3) on my computer. It works and I can upload without problem ! So the problem does come from the GIGA R1 board.
  • Following the "double click" advice found here. No change (though it seems that the Arduino board goes automatically into Reset mode when the upload fails).
  • To upload in both Reset mode or "normal" mode seems to change the error message :

In Reset mode :

Warning: Invalid DFU suffix signature
A valid DFU suffix will be required in a future dfu-util release
**Cannot open DFU device 2341:0366 found on devnum 26 (LIBUSB_ERROR_NOT_FOUND)**
No DFU capable USB device available
Failed uploading: uploading error: exit status 74

I also found this page, which says

dfu-util: Cannot open DFU device {vid}:{pid} found on devnum {n} (LIBUSB_ERROR_ACCESS). On Linux, this error can be caused by missing udev rules.

But we are on Windows 10, so I don't know how to proceed with that.

Finally, when the board is in Reset mode (green led blinking), in the device manager, I have the following peripheral issue @ Internal Flash 2 MB :

Also, it's worth noting that I can't update the firmware either (tools > Firmware Updater > Selec Board > No supported board connected)

I might try to run the suggested solution for Linux (with MobaXterm) but I don't have many hopes.

If anyone has a suggestion, that would be very welcome :slight_smile:

Many thanks in advance for the community's help :pray:
