First timer here… So please excuse me if I haven’t been able to explain my problem clearly.
I’m trying to flash my Photon locally, but the dfu-util is not able to detect the photon in DFU mode no matter what. I’ve tried two machines (Macbook Pro as well as Windows 8.1 laptop), every USB port available on both the machines and 6 different USB cables. The Photon is flashing yellow which indicates that the Photon did enter DFU mode. On Windows machine I keep getting error USB Device not recognised. On the Mac, while the Photon is in DFU Mode, the dfu-util -l command gives the following output
Found Runtime: [05ac:8286] ver=0151, devnum=7, cfg=1, intf=3, alt=0, name=“UNKNOWN”, serial=“UNKNOWN”
But as soon as I run any command on Particle CLI to flash the Photon, I get the following
!!! I was unable to detect any devices in DFU mode…
Your device will blink yellow when in DFU mode.
If your device is not blinking yellow, please:
- Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously.
- Release only the RESET/RST button while continuing to hold the MODE/SETUP button.
- Release the MODE/SETUP button once the device begins to blink yellow.
Error writing firmware…No DFU device found
Further in listening mode (i.e flashing blue), when I run the command particle serial list, it gives
No devices available via serial
Any ideas what might be wrong ??? Did I finally manage to break my Photon???
Thanks in advance…
