Greetings! I am trying to connect to an atmega328p-pu using a usbtiny built from the adafruit kit. I'm using avrdude 5.11.1 on Ubuntu 12.04 on a Lenovo Essential B570. I'm using a diy unpowered 6-pin target board a la Evil Mad Scientist here: http://www.evilmadscientist.com/2007/us ... et-boards/
The green LED lights when I connect the programmer and I get the "initialization failed, rc=-1" message and a brief flash from the red LED on the programmer. However, I get that whether the programmer is attached to the target board or not. I've checked the connections on the target board for shorts, haven't found any (a miracle considering my poor soldering skills!); I've checked that the pins are connected to the ZIF socket with success; and I've double checked the pinout of the 328p and I don't see anything wrong. I don't have an oscilloscope to watch what's going on on the pins.
I've attached a screenshot of my avrdude command and the error message, along with top and bottom shots of the usbtiny board. I can also attach shots of the target board if that will be helpful.
Thanks for any help!
