I have an AVR Dragon ICE, like this one: http://www.watterott.com/en/Atmel-JTAG-ICE-3-ATJTAGICE3
I have connected its squid connector to the ICSP connector on my Uno following this pin out:
When I connect my AVR Dragon ICE to my PC (USB) I get an orange status light, the Dragon gets listed in Atmel Studio, but the Uno's status lights are dark and Atmel Studio reports it gets 0v.
If I connect my Uno to USB, it doesn't light up, but if I connect the Uno and disconnect the Dragon, the Uno lights up.
But as soon as I even touch the USB cable to the USB connector on the dragon, power fails on the Uno.
I can't open the 2nd link (problem on my end most likely)
Are you connecting it up in SPI mode?
Sounds like you are shorting out the +5V on the Uno ICSP header, pin 2.
MISO 1 2 +5
SCK 3 4 MOSI
RESET 5 6 GND
Yes, I think I am shorting it/connecting +5 to GND and GND to +5
but I am connecting it just like http://forum.arduino.cc/index.php?topic=84190.0
I have checked the PIN orientation, etc... (I'm using a genuine UNO R3).
Are the pins backwards on that diagram? I don't want to do a lot of trial and error because I don't want to break my Uno.
