Long story short: I need to program my pro mini through ISP. I'm using the reset on the left side of the board, hole 13 is SCK, 12 is MISO and 11 is MOSI. I'm using a usbtiny programmer, but I cannot get avrdude to recognize the board. I get the old "initialization failed, rc=-1" error, but unless I'm horribly mistaken, everything is hooked up correctly. Is it possible that the MCU is damaged?
