I used an Arudino Uno to develop my code. I got in my PCB's for my project with blank Atmega328P's (link here).
As per this article, I got the impression that I could use the Arduino ISP (which I also purchased) to burn the bootloader onto the bare chips, as well as load sketches onto them.
I've followed the instructions on the previously mentioned page. I can load the bootloader with no errors from the Arduino IDE, I can also load the blink sketch with no errors. I have a LED attached to pin 0 on my board, so I change the appropriate lines in the code, but when I power up my board after uploading the sketch, I see nothing happening.
I've seen a few things about setting fuses properly, but I'm not quite sure how to do that using the Arduino IDE. My typical procedure has been to upload the bootloader to my board, then upload the sketch by using "Upload using programmer".
I would greatly appreciate some help from a more experienced person here...I'm having a devil of a time figuring this out and I am in over my head at this point. At this point, my goal is simply to get the blink sketch working on my boards...then move on to my actual code. :D
Please let me know if there is more info that would be helpful.
