I never got dfuprog.exe to work for me, so I used the LM flash util instead. I think that I could have probably accomplished the same thing with CCS as well.
dfuprog, hm that sounds awfully familiar. When I started my cartridge programmer, I had used dfu on an erased avr chip, unaware that it actually needs a dfu firmware on it to work in the first place :D next mistake was that I would need to dfu erase first, then prog over dfu. That took me a while as well to figure out.
I get what you are saying. That was one of the first questions I tried to resolve, however, there was definitely a voltage issue on the chip as well. I think that I may have got solder somewhere it should not have been, not enough to create a dead short, but still making contact where it shouldn't have been.
I have been running fast and loose with the whole design/build process for this board, as I wanted to get something together to show proof of concept before the end of the semester, and I did manage to 'fail fast', but it doesn't seem to be catastrophic. There are a lot of things going right, I just need to run the problems to ground.
I think I will have some time this weekend to nail down the firmware flashing process in a more controlled way, and will get it up on this project page.
