Cannot enter programming mode on Arduino Uno I have an Arduino Uno that I've been programming with an AVR Dragon through Atmel Studio 7.

I did two things in close proximity, and I'm not entire sure which action is the culprit. I tried using the DebugWIRE interface (for the first time) instead of ISP in the tool select screen. I also hit the Arduino's reset button as Atmel Studio was compiling/uploading to the Arduino (stupid, I know.)

Now I cannot program with ISP the normal way, or do anything really.  If I try to upload to the Arduino I get:



I've tried to use the device programming feature using the Dragon and change the fuses as I've read about in other posts and get:



I've tried burning a new bootloader with the Arduino IDE and the IDE tries ten times, but it tells me that the programmer is not responding.

When I plug my AVR ISP mk2 into a different Arduino Uno I get a nice constant green light. If I plug it into the board I've been discussing it blinks red.

I'm not sure where to go from here...
I think either the chip or the board is fried. Try swap the chip (only the chip) to the other board and retry loading the program.
