Coding Badly,
Thanks for the quick reply.
Checked programmers.txt, for some reason the version I pasted in dropped the l in serial, but my actual file has it spelled correctly.
Then I checked boards.txt, changed all the .upload.using entries from "=pololu" to "=arduino:pololu" as you recommended.
Success!!! I have a blinking green LED on my ATtiny85 board. Awesome. I then changed the board to from 1 MHz to 8 MHz and burned the bootloader, recompiled and re-uploaded. Success again.
I will now start exploring what I can do with the ATtinyX5s. I need to hook up the TTL serial port on my Pololu programmer so I can get a serial monitor for debug. Any questions or issues I will repost here.
So far the overall (your core + Pololu programmer) setup is Highly recommended.
Best Regards and thanks again.
George
