Ardrino Dock2 request reflash recovery proceedure



  • for some reason my onion2+ cannot flash the ardrino dock2. Seems like the atmega328p boot block now has the wrong code. When flashing from IDE 1.8.5, or flashing manually using /usr/bin/ardrino-dock,

    avrdude: Device signature = 0xffff03
    avrdude: Expected signature for ATmega328P is 1E 95 0F
    Double check chip, or use -F to override this check.

    avrdude done. Thank you.

    ERROR, flash NOT successful

    The Device signature changes every attempt! Grr....

    This is a common problem with atmega chips yet searching the net gives garbage answers and does not help at all with the onion version.

    Can the devs please write a recovery procedure to fix this problem and add it to the wiki...I am sure it will help allot of users out there. Also can the devs patch the ardrino-dock script to add the -F option?

    Presumably you are talking about the Boot Loader Section of the flash. Omgega2(+) with Arduino Dock 2 operates as an ISP programmer - so it doesn't use / doesn't need any bootloader program by default.
    The Signature Bytes are stored in another memory space and this special memory space is accessible through special undocumented programming instructions only.

    ("This is a common problem with atmega chips ..." - there are lots of misinformation / fake info on the Internet. ;-)
    If your hardware, firmware, the installed programs, the Arduino IDE on the host PC and all settings are OK then Omega2(+) with Arduino Dock 2 can identify the ATmega328P always correctly (Device signature = 0x1e950f).

    You should check your on-board AVR chip in a clean state again (after a Factory Reset).

  • thanks can you expand on

    @György-Farkas said in Ardrino Dock2 request reflash recovery proceedure:

    could you explain how to do a factory reset?

    and the avrdude command line switches for the omega2(+) with the ardrino dock2 (to reset it or manually program it)

    I've tried different combinations of

    root@Omega-:~#avrdude -c avrispmkII [and others] -p m328p -P /dev/ttyS1 /tmp/sketch.hex

    which errors out with:

    avrdude: stk500v2_ReceiveMessage(): timeout

    Thanks



  • @C-G If I were you I'd do this on the CLI - for example with these commands:
    firstboot -y
    reboot
    ...
    ssh root@192.168.3.1
    ...
    wifisetup
    ...
    opkg update
    opkg install arduino-dock-2
    avrdude -C /usr/share/arduino-dock/avrdude.conf -p atmega328p -c linuxgpio -P gpio -n -v

    This is my config: Omega2+ 0.1.10 b160 with Arduino Dock 2

    avrdude done. Thank you.



  • @C-G Bad news. Is the signature 0xff8dff on each attempt - or does it change to a different value with every attempt?



  • it changes:

    executing avrdude -C /usr/share/arduino-dock/avrdude.conf -p atmega328p -c linuxgpio -P gpio -n -v

    3x gives:

    1st run: avrdude: Device signature = 0xfff1ff
    next run: avrdude: Device signature = 0x318f7a
    final run: avrdude: Device signature = 0xffc840



  • @C-G (If I were you) Before I'd say that your ATmega chip (or your Dock or both) is corrupted I'd check it in another way too - for example with an USB ISP programmer or with another Arduino (as ISP programmer). Perhaps I'd try to read the signature of another ATmega328P with the Dock.

    I'm afraid the signature bytes on an ATmega328P (on any ATmega) are not writable with normal programming instructions. Please correct me if I'm wrong.
    I haven't tested the next speculative command - if you think you can try it on your own risk :
    avrdude -C /usr/share/arduino-dock/avrdude.conf -p atmega328p -c linuxgpio -P gpio -v -U signature:w:0x1E,0x95,0x0F:m
    Most probably it'll fail:
    avrdude: writing signature (3 bytes)
    avrdude: verification error

    I'm very sorry - I have no more idea.
    Maybe one of our @administrators will say some cleverness to you.

    Good luck.

    BUT, it didn't change anything:

    linuxgpio -P gpio -v

    (output muted for brevity)

    Seems like i need to burn a new boot loader, by using a 2nd ardrino as an "Ardino as ISP" programmer.

    https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader.

    The correct bootloader code is required for the atmega328p to accept programming from the serial port.

    I wonder if the omega has access to the ICSP port. If not, i have a spare uno i could use as a programmer, but i am unsure which IDE settings to use, as the example in the link is for uno to uno.



  • i fixed it by following this:

    https://www.arduino.cc/en/Tutorial/ArduinoISP

    the procedure i used was:

    upload ardrinoISP sketch to a spare Ardrino uno.

    remove all connections and omega2+ from the ardino dock2.

    connected the uno to the dock2 icsp port as shown in the 1st link.

    set ardrino IDE to board "Ardrino/Genuino Uno"
    set ardrino IDE programmer to "Ardino as ISP"
    set port to /dev/tty/ACMO

    selected "burn bootloader"

    disconnected the uno.

    reinstalled the omega2+

    now the dock2 is programmable via the omega2+ using

    set ardrino IDE to board "Ardrino/Genuino Uno"

    and

    Programmer "AVRISP mII"

    via the network port

    root@Omega-:~# avrdude -C /usr/share/arduino-dock/avrdude.conf -p atmega328p -c linuxgpio -P gpio -n -v

    reports consistently:

  • @C-G Congratulations!
    So the external programmer (the other Arduino) was reading the correct signature and that's how it was able to (re)write the chip.
    I don't fully understand the way your method works but that's not the point. The main thing is that everything is working fine now.

    Onion's official Arduino IDE setting (IDE >> Tools) is different than yours:

    Board: "Onion Arduino Dock"
    Port: "Omega-XXXX at_IP_address (Arduino/Genuino Uno)"
    Programmer: "irrelevant"

    vs.

    Board "Ardrino/Genuino Uno"
    Port: "network port"
    Programmer "AVRISP mII"

    But if this is working out for you ... that's your call. :-)

    Footnote:
    I'm sorry the original cause of the error was not revealed after all. I wouldn't want to reproduce it intentionally but if I accidentally stumble upon this error I'll try your method too.
