    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.
