title: Arduino - Burning Bootloader without External Crystal
body: <p>I'm trying to burn the bootloader to an ATMEGA328P - AUR, the 32-pin SMD variation with my Arduino Uno. I've tried the recommended way that the Arduino website suggests to burn the bootloader. However, I don't have the 16MHz crystal recommended, so I tried the workaround method they describe to use the internal 8MHz oscillator. Burning the bootloader gives me the "Yikes! Invalid device signature" error. Do you think there is an incompatibility with the chip? Problem with using the internal oscillator? Should I just get the crystal?</p>
