Can't Flash Windows 10 IoT Core


#1

I’ve been fighting the initial setup of the Windows 10 IoT core on my Dragonboard410c all night with no luck. I’ve make sure the hardware is OK by booting and installing the DragonBoard 410c Board Recovery image from SD, which worked very well (and is also how I realized the the USB host ports and the USB OTG ports cannot both be used at the same time).

I’ve tried programming the board using both methods outlined in Microsoft’s documentation https://docs.microsoft.com/en-us/windows/iot-core/tutorials/quickstarter/devicesetup#using-the-iot-dashboard-dragonboard-410c

When attempting to use the IoT Core Dashboard, it appears the device is never gets recognized. I never get beyond the message “To turn on Flash Mode :” even though the Qualcomm HS-USB QDLoader 9008 device shows up on COM7.

When attempting to flash the eMMC using the Dragonboard Update Tool, I get Error Code 6, which shows up in the log file (extra line breaks removed):

I’d really like to get this board up and running using Windows 10 IoT Core - any help would be greatly appreciated.
