I'm trying to program 8 ATTiny85's I purchased from ebay but I can't seem to get any response from them.

I have tried following several guides and even tried to use High Voltage Serial Programming using this guide on one of the chips with no success.

I've set up my UNO as a programmer and using the debugging lights can see that part is working. But I keep getting the response "Device signature = 0xffffff" on all 8 chips.

The latest thing I have been trying to do to check that they are even working is burn bootloader with the following command

C:\WinAVR\bin> .\avrdude -v -p t85 -c stk500v1 -P COM13 -b 19200 -e -U efuse:w:0xff:m -U hfuse:w:0xdf:m -Ulfuse:w:0x62:m -F -B 5

and this response:

Would you like this fuse to be changed back? [y/n]

If I enter 'y' it gets stuck in a loop trying to change the hfuse.

Any help would be greatly appreciated.

EDIT:

Any time I have run the below command on the chips

C:\WinAVR\bin> .\avrdude -v -p t85 -c stk500v1 -P COM13 -b 19200

    \$\begingroup\$ Either you're making a systematic error in wiring up the connections, or you bought a batch of fake or defective chips. Both scenarios have been known to happen… \$\endgroup\$ – microtherion Jul 28 '15 at 2:38

    \$\begingroup\$ If you have mistakenly reprogramming the fuse-bits such that the device is expecting an external clock then the results you are observing are about what should be expected. However, if you have since tried the HVPP, as you say, this should clear any fuses and reconfigure the device to use the internal oscillator. Microtherion could be right, unfortunately. \$\endgroup\$ – sherrellbc Jul 28 '15 at 3:09
  • \$\begingroup\$ The best advice is to not buy parts on ebay. Use a reputable dealer like digikey, or even from places like Sparkfun or Adafruit. Also, if you plan on programming bare chips, don't use Arduino as a programmer... get an actual programmer from Atmel. Even the AVR pocket programmer from Sparkfun will work fine. \$\endgroup\$ – Kurt E. Clothier Jul 28 '15 at 3:37
  • \$\begingroup\$ Are you trying to program all of them at once? To see if you can even talk, just do AVRDUDE -p <PART> -c <PROGRAMMER> -P <port> -V .... the -V will return Verbose information from the chip like the device signature and current fuse bytes. You shouldn't need to use the -b option unless you have already changed the clock timing on the chips. \$\endgroup\$ – Kurt E. Clothier Jul 28 '15 at 3:40

The issue appears to be with the Arduino UNO as an ISP. I connected up a USBASP device and ran the following command:

.\avrdude -v -p t85 -c usbasp

I have now successfully programmed a couple of the ATTiny85's with the slightly modified Blink sketch using the Arduino IDE (1.6.5)

I still have no idea why the Arduino UNO would not be working as a programmer.
