Re: Arduino Dock not working

Hi Victor
seems we have the same problem http://community.onion.io/post/15186
happy to not be alone. i also tried like everything (except bootloading because i just have the Arduino dock 2)

But i seems that you went further and even this didn't solved the problem, so i can spare more headaches.

[O2+ with Arduino Dock 2]
After leaving the Onion take dust for over 8 months because of this problem i gave it a try today ..
No success ... i was reading this thread again from the whole beginning and tried litteraly everything.

i confirm that :

• all this was done on a fresh new installation of last Onion firmware
• i added the lines in boards.txt (as you can see further my arduino IDE recognises the board)
  i use arduino 1.8.5 but anyway even via ssh with the ino in /root/ folder i have the same damn error
• i have AvrDude 6.1 installed (not the newest from LEDE package)

Still the same error i had 9 month ago, directly in SSH or on Arduino IDE

i don't have the buggy AVR-dude from later versions (LEDE Package Repos are commented out) / i have v 6.1

ANYWAY => same error, in IDE like in SSH

HELP ! i tried everything, spend hours having an headache because of this ...

The only thing i didn't do is to try to flash again the bootloader
(because i just have the Arduino dock and it would be a pain in the ass to put these wires on ICSP ...
anyway it might not solve the problem
this procedure : https://wiki.onion.io/Tutorials/Arduino-Dock/Initial-Setup#arduino-dock-setup_using-the-omega-expansion-dock-with-the-arduino-dock-icsp-header

do anyone did this ? flash the ArduinoDock2 from Onion2 while the onion is currently on that dock ?

I beg for help im desperate. I backed Onion to be able to use it with Arduino and it does not work.
is it possible that the dock or arduino itself is defectuous ?

@frederic-raducki Hey, did you make any progress on this topic? While I've now already ordered the OLED expansion I'm still considering getting the OLED screen from Upgrade Industries (since it's easily available at a maker store down the road) you had mentioned and playing around with it in the meantime.

So any advice and recommendations would be much appreciated. :)

sorry nope. since Arduino AVR dude does not work my Onion2 is collecting dust and i learn Raspberry gpios ;-)

@Ls-Song said in 3D files of boards for case design.:

For instance the Arduino expansion board has no screw holes and makes it difficult to mount on something else...

+1 on this! still awaiting ArduinoDock model desperately.

Sketch uses 5042 bytes (15%) of program storage space. Maximum is 32256 bytes.
Global variables use 199 bytes (9%) of dynamic memory, leaving 1849 bytes for local variables. Maximum is 2048 bytes.

avrdude done. Thank you.

No luck :(

you have the same error as me right ?
i ordered another omega2 on indieGogo .. i hope that wen i receive it i will be able to compare if my 2nd still has the same issue ...
for now i just dont use the Omega and i purchased a RaspberryPi3 to learn meanwhile i have a fix for Avrdude

@David-Wickenden said in Omega 2 and Arduino dock.:

@frederic-raducki
sometime I found my problem related to wifi, and yes, once I put it down it works but when I put it down again it won't work, I have tried not to touch it once it made connection, still works.. I am about 3 metres from the router which is a good distance.

sure, thank for the suggestion but as you can see in screenshots higher: even a manual procedure with avr-dude fails :-(

hello, i had this issue
see this thread :
https://community.onion.io/topic/1291/solved-i-may-have-bricked-it-empty-folders-instead-of-console

any clue ? (up)

how can avr-dude be "broken" ?

i do "opkg remove" of everything related with arduino (dock1, dock2, avr-dude ..)
i reboot the system.
then i reinstall each of these ( pikcing of course only one of the 2 docks cause they can't be used in the same time, anyway mine is the _2)
i reboot the system just to be sure ...

Arduino IDE recognizes the board via WIFI, i can even inout the board PASSWORD ...
but then this damn problem occurs.

i suspect it's the communication between the Omega and the ATmega that is going crazy.
What should i do ? should i downgrade to the firmware that had CLOUD registering broken ?
cause with that plugin i COULD ACTUALLY upload sketches.

i beg anyone to help, i'm starting to be fed-up with this.
