@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

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

I added the -F switch:

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/ACMOselected "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

@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.
-
@C-G Thanks so much. This totally worked. Don't forget the 10 micro-f capacitor between ground and reset on the programming Arduino.
-
@Matthew-Lousteau Take that back. I reacted too quickly.
-
@Matthew-Lousteau OK. so it works, but if I have a ground pin connected into my project, it won't let me flash my sketch. If I disconnect the ground pin, I can flash the sketch and reconnect the pin afterwards and the sketch runs as I expected.
