I recently bought a dozen ATtiny85 MCUs and I was trying to test one simply by putting a blink program on it via the Arduino IDE with and AVRISP mkii (Arduino 1.0.5, Ubuntu 13.04). I kept getting an error suggesting that it wasn't wired correctly, but I've checked it multiple times (and it's powered externally at 4.8v). I even tested multiple ATtinys so it's very unlikely that they're all duds. When I switched to using my Arduino as ISP, it programmed fine. I tried using
avrdude -c avrispmkii -p t85 -P usb -t to see if it was a problem with the Arduino IDE setup, but that gave me the same error. I set all the
/etc/udev rules correctly as far as I can tell, and still no dice...
So I booted into Windows 8, installed Atmel Studio 6 and the drivers for the AVRISP mkii. I updated the devices firmware (to 1.16), and then tried to read the signature of the attiny85. This failed, giving me
[ERROR] Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00, ModuleName: TCF (TCF command: Device:startSession failed.). I tried it again, this time with the atmega328p from my arduino, and once again it failed. The ISP clock is dropped to 125 khz (and I've tried lower too). I know both the atmega328p and attiny85 are working still and the fuse bits were never tampered with (the blink program on the attiny from when i used my Arduino as ISP still runs).
Does this mean that my avrisp mkii is dead? All the LED lights behave exactly as expected (LED turns green with power is given to the MCU, red otherwise. USB LED is solid green and flashes when theres traffic). Additionally, it's recognized by both Windows device manager and Atmel Studio 6.
