Topic: Error: avrdude: verification error... (Read 1 time) previous topic - next topic

I get this error for every sketch I try to upload:
Code: [Select]

Binary sketch size: xxx bytes (of a 30720 byte maximum)

avrdude: verification error, first mismatch at byte 0x0000
        0x0c != 0xff
avrdude: verification error; content mismatch


The TX/RX lights blink so its clearly sending data to the chip but no sketch works.

My Arduino is a 328 Duemilanove.
This is a new problem, I have been using my Arduino for over a year now with no problems.

Did my bootloader die? Or the whole chip altogether?

Any advice is appreciated.

It almost sounds like you have the wrong board selected. Very that the the board selection
is correct.

Yes that was one of my suspicions as well but the board is set correctly to "Arduino Duemilanove or Nano w/ATmega328" the first one in the list.

I also tried reinstalling FTDI drivers but I am still getting the same error.

In your preferences file try changing the upload.verbose to "true" (no quotes).
Maybe there will be some additional information that will help.
I just found this option today when troubleshooting an avrdude problem.

Here's what I got from the verbose mode:

I can't really see anything useful but hopefully you can.

Is that all of the messages? When I ran verbose I was able to
see the avrdude command line (which is how I solved my
Makefile issue). It would nice to see the command line
switchs that are used.

Yep that is all I get. No command line.
I am using version 18. The text I posted shows up in the bottom black box in the Arduino software. I had to add the verbose thing inside preferences.txt because it was not originally there. Perhaps that is relevant.

jluciani

I wonder if the command line scrolls out of the buffer?
On my Linux box I read everything from the terminal
window.

I am on 0017. In my preferences.txt file there was a line
Code: [Select]
upload.verbose=false
which I changed to
Code: [Select]
upload.verbose=true

The only thing I was going to check for is the baud rate. Sometimes
slowing the baud rate can help. In my Makefile I am using an
upload rate of 38400.

jamieriddles

I tried lowest baud (300) and some other random ones as well.
When I searched "upload.verbose" on Google, I noticed a similar option: build.verbose.

When I added the setting "build.verbose=true" I got this:
http://stashbox.org/823519/textupload.txt

jluciani

build.verbose gives you all the output of the compiler.
Unfortunately the issue is with the upload which requires upload.verbose.

jamieriddles

I see.
When I saw the command line switches I thought it might be worth posting.

I am having practicaly the same problmes. When I try yo upload a sketch (any sketch) I get this:
Code: [Select]

avrdude: verification error, first mismatch at byte 0x0012
        0x2f != 0x31
avrdude: verification error; content mismatch


The Tx and Rx LEDs blink - standard indication of an upload. But after the upload is finished - I get that error. And the boad still runs the skectch that was uploaded before I got this error. I tryed unpluging the board, restarting Arduino IDE, selecting the correct board again... But nothing helps.
