  • I was stuck on the Ubilinux installation procedure, where Windows flashall.bat invokes dfu_util, which emits 3 error messages and doesn't download anything. The errors are: Device has DFU interface, but has no DFU functional descriptor Same error, 3 times. Then the Edison proceeds to boot the default Yocto (seen on the putty console).

    I found the problem is my Windows system is missing the Intel driver set, available at: https://communities.intel.com/docs/DOC-23242 , select Windows Driver setup 1.0. Just run it. Includes RNDIS (remote network driver), Composite Device Class, & DFU. Then unplug and replug the Edison once, to allow Windows to match and load the driver. I did unplug and replug a second time.

    Now go back and reinvoke flashall.bat, and "Dfu device found" shows in the cmd window, and it proceeds to download stuff...as below. Your Tutorial should mention installing the Intel drivers!!
