Online Instructions say to select "Uno wifi rev2" for board type...this selection isn't available! I've redownloaded the application to be sure there wasn't any updates, etc..the application recognizes the proper port but is saying "Atmel Atmega328P Xplained mini" as the connected board! I selected that as board type, but still cant get a program as simple as "blink" to load.
That's because you haven't installed the Uno WiFi Rev. 2 board package.
Tools -> Board -> Boards Manager. Select "Arduino megaAVR boards" and click install.
Thank You!!! Ive been reading and going nuts for 3 days trying to find that simple information. Sure would be nice if they sent a heads up with the new boards to tell you to load that file! I had looked there but had no idea it wasn't called wifi rev2!
Thanks again!
You're correct that the documentation is missing this important information. That has been reported to Arduino here:
Hopefully it will get documented soon.
