- If you are adding the FPGA just to have a CPU core, you have too much money or you work for the government.

D. None of the above

BTW, OTS solutions work great out of the box until you start adding your own drivers and such, then the fun begins... kernel re-compiles, build tools... you will have to deal with this in NIOS development too...

Don't I know it. In a previous life I was knee-deep into 8051 territory, most of it assembler (drivers and rt kernels), upwards of 500k lines.
I have a genetic defect that enjoys optimizing code & debugging, so it's not all bad. ;-)
As for the FPGA route, it's not for this app, but I will keep it in my back pocket for the future. The geek factor of a totally configurable "virtual" device is appealing, but my age has taught me that it's potentially a serious time vampire.
So, it's AVR for me. Wide product line, app notes galore, good dev suite & libraries and tons of cheap eval boards.
ARM is very cool, (and cheap) but spread among too many vendors, so support seems very variable.
Many thanks for helping me clear the fog.
No longer confused Bob.
