Tutorial: Installing DFU-Driver on Windows [24 Feb 2015]

[Bootes]

I tried for hours to get this to work on my windows7 machine. The dfu-util would never see the core. I finally read on another post that the dfu-util doesn’t like usb3 ports. I switched to a usb2 port and volia it works.

If dfu-util doesn’t see it, change it to a usb2 Port (usb3 didn’t work for me)

what do you mean exactly mean by

@kennethlimcp

make sure your path is that where dfu-util.exe is

I did all the above but I can't find dfu-util.exe and when I write dfu-util in cmd I get:
'dfu-util' is not recognized as an internal or external command......
What is the problem?

[peekay123]

@mohmhus, Windows has an application search path. Open a CMD prompt and type “path” and you will see what your present windows search path is. For dfu-util to run from any directory, windows needs to find it. It does this by looking in the search path. You need to add the directory where you put the dfu-util.exe (and supporting files) to the path.

You can find help on doing that here or by googling “windows add to path” for example.

If you look at the end of the tutorial, i have already provided a link on how to do that

[mohmhus]

Thank you very much
The problem was that I didn’t know what a .tar file is

Hello,

Is it working for Photon?

Thank you

[Moors7]

Yes.

[FrankieMa]

Thank you. I have tried it and no problem.

1. Launch 'cmd' (make sure your path is that where dfu-util.exe is)

I tried to follow this step by step got the dll installed. then i hit this line. I did a search on my PC i don't have dfu-util.exe was that application supposed to install that as well?

I managed to get my photon stuck in safe mode was trying flash tinker to it. Ended up resetting it using my phone. Let me know how to get this to work because being able to flash code from my pc instead of the web interface will be useful seeing as the web interface doesn't have any form for source control.

For Windows, this might be interesting as well

Particle CLI Installer (Windows)

We now have a straightforward way for people to get started with the Particle command-line interface (CLI) on Windows. It’s a simple installer that installs the CLI and the drivers needed. Once installed the Particle CLI will keep itself auto-updated. Install Particle CLI through here Note: If you previously had the CLI installed through npm, please do npm uninstall -g particle-cli before running the installer. A similar auto-updating installer is in the works for Linux and Mac OSX. For m…

I use CLI so it is installed. However it wouldn’t let me flash anything with out DFU-UTIL which i did a search on my pc and doesn’t exist.

I ran that drive program which i would assume would install the DFU-UTIL driver. Seams i missed where to get the DFU-UTIL from.

I will try this again the next time I manage to lock my photon in safemode.

[Moors7]

That installer should also install DFU Util for you, hence the suggestion. It really does make things easier.

There's also this guide that should tell you how to get DFU Util going manually:

Tutorial: Installing DFU-Driver on Windows [24 Feb 2015]

So it seems like some owners want to go slightly advanced but instructions for installing the DFU-driver is a little vague. How to put your core in DFU-mode Press on BOTH buttons Release only the Reset button Release the Mode button once the core start blinking yellow This will be the dfu-mode Pre-check! If you have somehow done this process previously but is unable to use dfu-util successfully, you will need to uninstall the DFU-driver 1st Put your core in DFU-mode Ope…

You can also flash via particle flash --serial firmware.bin
But getting dfu-util is never wrong

And the place where to download it was provided in my previous post!
