I downloaded the new EV3 software from Lego and installed it on Windows 7. The EV3 software runs. I plugged in an NXT using a USB cable. EV3 can edit the memory on the NXT and remove programs/sounds/text files.
I created a program that uses the large motor to spin the B motor 1 rotation at 75% power. The end program block finishes the very small program.
It downloads without complaint. Run it and the NXT complains with "File error!".
Is this a known problem? Is there a fix?
The NXT has firmware 1.05 loaded.
