I don’t think the power supply is the cause. For I can flash the KVIM official Android image with power supplied by the same USB port in the same Windows PC. The only different is the Update.img, one is compiled by myself according to the Khadas Doc, one is downloaded from Khadas firmware page.
Besides, I have flash the Android 6 update.img compiled by myself successfully with same Windows PC at the same USB Port.
Still, I tried to use the SD Card to burn the image, and it get success. The log is :
