Just got a few photons. WiFi, deploying apps via website all works. Now playing with the command-line tools on the Mac.
particle flash --usb play1.ino
says first that it found “DFU device xxx”, and then prints the error message from the title. Any ideas?
dfu-util is installed. I executed the command while the LED was flashing yellow.
AFAIK particle flash --usb only works for .bin files.
To turn your code into a DFU flashable binary you’d need to build first via
particle compile photon play1.ino --saveTo firmware.bin
Which will result in a firmware.bin that can be --usb flashed.
Or, simply running particle compile photon play1.ini will compile to photon_firmware_xxxxxxx.bin.
