Well, the intent is that you don't buy a blank AVR unless you know how to program it....
..., we can put together a little guide. It looks like most programmers can handle the ATMega, so there's really only a couple of steps involved. At the simplest, though, if you are starting from a blank AVR, you can either program just the firmware, then mount it in the TI for the rest (that was the intent, it's the simplest and only needs to be done once), or you can program the firmware and the GROM data at the same time (quicker since there's no TI program stage, but a little more complicated and requires the data to be prepared for this approach). If the AVR isn't blank, you can do the same or just use GROMCFG on the TI side.
Yeah, I'm one of those guys that bought one without having a clue what to do with it. I figured if I bought one when I bought everything else, I'd at least have one on hand when the time came or I needed it.
A guide from starting with a BLANK AVR would be awesome! I agree having the TI do the second makes more sense as it's part of the TI hobby.
I personally believe that more people would get into this stuff if they had a guide or documentation to 'hold their hands' the first couple of times to get them though the unknown learning curve.
