Hi, I did mine using a MAX232 IC to the ATMega 328 on a breadboard..

Here are some items to check/troubleshoot :-

  1. Make sure the Rx/Tx pins are correct... Pin 2 (RX) & 3 (TX) on the chip

  2. DTR connected to Pin 1 for "auto reset" with a 0.1uF capacitors ( not sure why... )

  3. Speed should be 57600 for uploading..

If DTR is not connected, try to press the reset button a few sec after pressing the Upload button...

Not so sure about the crystal tho..

Hope this helps..
