I've been following this but I've had zero luck: https://www.arduino.cc/en/Tutorial/ArduinoToBreadboard
Circuit is exactly as laid out. I've checked, double checked, fixed my reset resistor, and it's how it should be.
The board I've designed uses 3.3v and an 8MHz external crystal. This matches the Arduino Pro/Pro Mini 3.3v/8MHz profile, so I've been using that when attempting to burn the bootloader.
This is the error I'm getting:
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x03
Is there a special step that I'm missing to get it to burn to a 3.3v setup? I came across this thread but still haven't had much success.
Any suggestions are greatly appreciated.
