I am trying to change the controller on the arduino board, so I put a new one and same controller "Atmel Atmega328p-pu". But when I try to upload a sketch at the new controller, presented a problem. The softoware says me: Problem uploading to board avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Why does this happen? What am I doing wrong? I need to change something else in the software settings?
