How to install and use commands “dfu-util” in window system

[wangrj]

I see the problem here.  use the dfu-util command in the window system 

and i tried many methods and failed    The following is my reference website

http://zadig.akeo.ie/ 

Windows · libusb/libusb Wiki · GitHub   

Using zadig to install the USB driver, my pc device manager can recognize the nrf5340dk board

dfu-util Homepage (sourceforge.net)

MSYS2     

Building dfu-util from source (sourceforge.net) 

use msys2  download libusb-1.0.26 and dfu-util-0.11  source code  and  install them 

at this time first try run  build/bin/dfu-util.exe --download  failed 

and follow this tickt add patch  ,delete folders ( libusb-1.0.26 , dfu-util-0.11 and build) retry again

failed

I recommend using mcumgr instead.

Are you updating the device through mcuboot or the application?

If you do it through the application you can check out the smp_svr sample and the DFU Application guide. If you do it through MCUboot, you could check out the DFU MCUboot guide (an old NCS version is used (NCS v1.4.0))

Does this sound good?

Best regards,

Okay, I understand. I don't have too much experience with this, but I'll see if I can get it to work. I guess you're using the USB DFU application as a starting point?

Could you also try to ask the Zephyr community? Maybe on Zephyr Discord, or you can create a GitHub Issue or ask in https://lists.zephyrproject.org/g/devel/topics 

Best regards,
