Do these things go bad regularly? I have 2 of them, and as of yesterday I cannot program either of them. 2 days ago, I could write a program to one of them, and now when I try, it fills the window with the "xx found, expected xx" messages and will not program the chip. I can still successfully use the emulator with the romeditor to run my car... in fact, that is the only was I can run my car, so I have to have my laptop running to use my daily driver. Could I have done something to mess these chips up? Any suggestions?

 

voltage? spikes can kill those chips, or static when handling them , or too much voltage from not having the settigns righ=boom .
i dont knwo if thats the case with you, but al logical things to look out for .

 

anyone know a good and quick place to get some replacements?

 

whats the model # on the chip you have there?

 

Atmel micros are only good for 100,000 write cycles. How many times have you changed your fuel and timing maps? Just kidding.

You can get Atmel parts from Digikey.com pretty cheap.

Just match part numbers.

BTW-They are static sensitive.

Yeah, if you put the chip in the Pocket Programmer right away, before you download the .bin file, it can heat up the chip.
