Setting mode and device parameters.. OK!
Entering programming mode.. OK!
Erasing device.. OK!
Leaving programming mode.. OK!

It means you need to go to 'Device and Signature Bytes' in the AVR connection window and select the correct AVR.

Click 'Read Signature' just to make sure.

You much have been using the STK500 or higher....

Look, many sources can cause this problem...

Where is the chip on... is it on the programmer...
If yes, try to lower the voltage... what is the chip...
I was using the ATMEGA128L and found out that it was not going to be programmed unless I lowered the voltage under 3V8 ~ 4V...
Although operating voltage is 2V7 - 5V5...

Also check the oscillator fuse bits.... what type of oscillator you use matters...


Good thing with STK500 & higher programmers is that you won't have problem with fuse bits... and locking the device....
Also check your wiring if the chip is not on the programmer...

P.S. I've been inactive for almost a year... Don't give promises but I'll try to complete my tutorials. I'll let you know when..

Cheers!

well it appears that it took my program after lowering my ISP Freq from 1.0 MHz to 125.0 kHz

and its a ATMEGA8-16PU
