Thread: avrdude: verification error, first mismatch

    Thank you for responding, but if you look at the image number 6, you can see how I used the option to load using programmer.

    Is the correct Programmer to choose and you do need to select the appropriate COM port for it.

    I should again try to digg up my setup... Not sure where it is sitting right now as I am not doing anything these days with the Arbotix boards.
    Yes, it is the same ISP Programmer.

    I tried the two COM ports that came out...

    Again not sure what to tell you. It looks like your setup is correct.

    I could not tell what version of Arduino you are using. Probably should not mater.

    I did drag out my setup, which is using the same programmer (Pololu) it created COM8 and COM9 and on my machine Com8 is the right one.

    I was able to burn bootloader and I was able to upload blink (changing pin to 0) using upload using programmer and that worked.

    So the only thing now would be to contact Trossen Support. See if they will send you a new board?

    Again these days I would not recommend buying these boards for many reasons, but would probably stir you to some better supported boards like openCM9.04... As if you look up at Trossen's website you will see their new Arms are now shipping with these!

    Thank you very much, you have been helpful.


    I bought another Arbotix, because in one month I have to present my project, and I have everything done for Arbotix and I do not have time to change.


    For the next project, I will use openCM9.04.

    Best Regards!!

    Good afternoon again.


    I have already bought my new Arbotix, but I want to try one last thing to try to fix the one that is broken.


    I want to reinstall the firmware. Can someone tell me where I can download it? Is there any guidance I can follow? Could you advise me how to do it?


    I have already installed the Atmel Studio 7.0


    Thank you very much.

    The only firmware for this is the Bootloader. Which is what Arduino command is trying to do.

    And on my machine the Arduino install that I am using (My own for 1.8.5), the files are installed at:
    C:\Users\kurte\Documents\Arduino\hardware\arbotix\ avr\bootloaders\atmega644p

    Which are up in my Fork/Branch of the Arbotix project:
    https://github.com/KurtE/arbotix/tre...ers/atmega644p

    Probably same binaries exist in all of the branches/forks...
