Topic: Errors trying to get the default Blink program running (Read 840 times) previous topic - next topic

I am getting the following error when uploading the standard blink program:

avrdude: verification error, first mismatch at byte 0x00000x0c != 0x04
avrdude: verification error; content mismatch

I am using the Arduino Duemilanove: Atmega328 board
OS: Windows Vista 64-bit

is this indicating a problem with the board, or the uploading process?

In most cases the avrdude error messages are not very helpful so it's difficult to say.

Have you ever successfully uploaded a Sketch to the board?

What do you have connected to the board?

Are the FTDI drivers up-to-date?

I just got this board for a school project and have yet to use it for anything.

I have been running through the Getting Started w/ Arduino on Windows guide on this website and have yet to connect anything to the board.

I am assuming windows installed the latest drivers when I initially connected the board.

From where?  Used?

You are certainly a trusting sole.  Go to Device Manager and confirm that the latest driver is installed.

Used board from school.

Driver date: 18/03/2011
Driver Version: 2.8.14.0

that is the latest driver version I can find.

Getting the same error on a different computer running windows XP.

It is time for a loop-back test...

1. With the board DISCONNECTED FROM THE COMPUTER, either remove the processor or connect a jumper from GND to RESET.

2. Connect a jumper from pin 0 to pin 1.

3. Connect the board to the computer.

3. Open your favourite terminal program.  Serial Monitor will work.

4. Open a serial connection from the terminal program to the board.  The baud rate is irrelevant; just pick something.

5. Type / send some data.


Was the data you sent echoed back?

I need to get some supplies and have a bunch of other stuff to do today. I will try your suggestion Coding Badly later on. Thanks for the help.

Took the board into the school to get them to test it. They ran into the same error on their computers so they took it back and gave me a new uno board to use instead. They also told me that a few of the older boards had burnt out micro-controllers on them so I am thinking that was probably the problem with this one too.
