Quote from: Loudhvx on Mar 02, 2011, 08:39 pmI was under the impression that the SparkFun atmega328 with Arduino bootloader pre-burned was able to go into the socket on the UNO and work just like the original UNO.Nope - not mine. Will be interesting to see if yours do. I"ve now tried all 3 I purchased.

It should work, you just can't select the Uno as the board type, but rather the prior 328 board type (one with the funny name)
I've double and triple checked my circuit and it looks fine, and yet it still refuses to upload.
I think its jinxed.I've tried the simple circuit which doesnt require caps and a xtal - doesnt work.Added in decoupling caps - doesnt work.I'll start from scratch tomorrow and maybe it will work
:Be sure to select "ATmega328 on a breadboard (8 MHz internal clock)" when burning the bootloader.
I tried doing just what you are attempting and failed. Resorted to putting the chip in an arduino, uploading the sketch, popping it out and putting it into the breadboard circuit. That worked. I'm curious to see if anyone has a solution that actually works to upload a sketch from a chipless arduino directly onto a breadboard mounted chip.
I built something for that a while ago, but doesn't require taking the chip out of the arduino:http://arduino.cc/forum/index.php/topic,8084.0.html
The problem with the "Uploading Using an Arduino Board" example, is that they don't tell you that you need a wire connecting the 2 reset pins.
