Arduino dock error



  • I've scanned through the forum for similar errors with the arduino dock but have not found anything helpful. Any assistance will be greatly appreciated. I get the same verification content mismatch error result flashing via IDE and via SSH. Here is a screen dump:

  • @György-Farkas > Output vs. Output on Arduino Dock 2

    Hope this helps.

    Thank you for this - unfortunately no change by changing the direction of gpio 17... back to drawing board



  • @Paul-Cousins
    Do you try to flash the MCU of a genuine Arduino Dock 2 with Omega2(+)
    or try to flash "in-system" the Arduino Nano of your nice real-world Onion project?



  • @György-Farkas I am using the arduino dock 2 - tried to flash it via the arduino ide and also via the shell script. have not tried in circuit pins as I don't have a cable for it



  • @Paul-Cousins
    Sorry, I don't have any more (useful ;-) ideas.
    If you can find what causes the error let me know please.



  • Still no luck @György-Farkas . I removed and installed fresh code, tried other sketches - still get the same error but at different hex addresses... beyond frustrated! :(



  • Just a quick update: I tried to flash the arduino dock 2 with an arduino uno in ISP mode and the omega removed from circuit. According to the IDE there were no errors and the blue led on the dock flashed during programming indicating some activity. The dock however does absolutely nothing afterwards - blink does not blink and none of the other sketches I tried had any activity with or without omega in circuit.

    Can't say I am too impressed with the dock at this stage and the many hours spent on it with no return. I am rather going to design my own.

    @Paul-Cousins

    The program you are trying to flash in your screen output requires 100% of the Atmega's flash memory. If you're using the Omega as the programmer, it will set the fuses in a certain order, including how much space to set aside for the bootloader. It may be that your sketch needs to be written to write-protected space and thus the verification fails.

    I would suggest modifying the fuse settings at the top of /usr/share/arduino-dock/arduino-dock-lib.sh so that they read like this:

    EFUSE="0x05"
    HFUSE="0xDE"
    LFUSE="0xFF"
    

    Try that and let us know how it goes.

  • Thank you @Gabriel-Ongpauco. Still no luck with that modification and i am writing blinker.ino test sketch which is only 2% of the max memory.

    Sketch uses 948 bytes (2%) of program storage space. Maximum is 32256 bytes.
    Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
