Hi
I connect arduino Uno to Dragino Yun Shield.
After configuring everything, if I try to load the sketch through wifi I get this error:
avrdude: Expected signature for ATmega32U4 is 1E 95 87
Double check chip, or use -F to override this check.
How so? What should I change to risovere this problem?
thx all 
Got the same error ... and do not understand where am I supposed to use the "-F" command ...
Anyone has a clue ?
You have the wrong board selected.
The Arduino Uno has an ATMega328P; you have selected something that uses the ATMega32U4.
Even with that shield on it, the board you are using is still an Arduino Uno, not a Yun
