The new EV3 software tells me to update my firmware on the NXT. When I go to the tools menu and select update firmware it tells me the NXT brick can not support this function.
Same problem here. Looks like on the NXT you need to move the firmware file to a directory in the lego mindstorm software directory and click on update firmware in the NXT software.– user3013Oct 4, 2013 at 22:14
I don't really believe that ev3 firmware can be ran on NXT, but... Has anyone tried to copy ev3 firmware and import it with NXT software?– user6011Jul 21, 2015 at 20:12
EV3 software will not download firmware to the NXT brick. For that you need the NXT-G software and a downloaded firmware file from Lego. 1.31 is the latest version.
So if you're running EV3 on NXT, you shouldn't throw out the NXT-G software. Once in a while, it's still needed.
