I bought the avrisp mkII programmer and I have the atmega168 mcu. When I try to program the mcu I always get (Entering programming mode Failed!).
1) The programmer status led is green
2) I have been able to program the board before, but all of a sudden it doesn't work. ( I have checked voltages and soldering )
3) I tried all possible clock values for programing.
I don't have any idea what could be wrong other than a fried mcu.
** my only alteration to my board from the design, is that I shorted solder across the led. I t wasn't working in either direction, so rather than trying to pull it out of the board I just shorted across it. I was afraid the led would not allow current to continue to flow through it (I'm a ME not an EE lol i don't know these things).
