Were you (phineasjw) talking about optiloader.h
in the Adafruit Standalone-Arduino-AVR-ISP-programmer enhancement of "optiLoader"? I can't find an "optiboot.h" associated with ANYTHING, and the original optiLoader and optiboot source doesn't contain any mention of CLOCKSPEED_FUSES...
If I had 1000 boards for some real project, I'd be buying a production-quality AVR ISP programmer.
? (no personal experience with that, but Kanda has been around for a long time and has a decent reputation.)
If you're willing to sacrifice a board that consistently fails to program, I'd be willing to take a look at it and see if I can figure out what is going wrong. (get a shipping address via pm)
