I have touble to flash my code to an Electron device on Windows 7 using the following command:
particle flash --usb firmware.bin
I have followed the instructions carefully to enter DFU mode. The light shines yellow. But “particle” command still complains that it cannot find any DFU devices. But I can see “Photon DFU” in the Device Manager of Windows 7.
How to deal with this issue?
