Flash varification error for atmega128

[shindehari]

Hi,

I have designed a atmega128 based board. I am programming the chip using avrdude. Previously I was able to programm the chip without any error. Currently I am getting an error of " flash varification error at x address".
Please let me know how to get ride of this error.

Thanks.

Hi,
1. Please post a circuit.
2. Please provide your OS and PC type.
3. Is the processor connected to anything else but the programmer?
4. Can you test with a second processor?

You may not be able to get rid of it - it seems as if one memory location is faulty. This happens (occasionally) and all you can do is replace the processor.
