I have a ROCK CM3 module plugged into the ROCK CM3IO board.
I am running windows 10 and have installed the RKDevTool and driver.
I am following the procedure in https://wiki.radxa.com/Rock3/installusb-install-radxa-cm3-io
but I cannot seem to get the tool and the board to talk over the OTG USB port.
I hold the gold button down then apply power.
I have previously run from a SDcard.
RKDevTool just displays “No Devices Found” any help would be much appreciated.
Kind regards,
Dave.
