I have been able to successfully flash the standard image using the OTA method, however the flashall method fails. My flash.log file says
"Cannot open device
dfu-util 0.5
dfu-util does currently only support DFU version 1.0
Filter on vendor = 0x8087 product = 0x0a99"
I am not receiving any bitbake errors, it is reporting 100% successful compilation for me.
