Hi,
Has anyone successfully used DFU on an rk3288 or dwc2_otg based board? When trying to download a binary to the board over DFU it currently seems to timeout and the transfer fails. I have tested the firefly-rk3288 and also the Tinkerboard.
I have successfully used the same setup on an am335x beaglebone black on the same U-Boot commit.
