Omega 2 and Arduino dock.

@cusackph Aye, these are the kinds of things you only learn over time. What's worse is that us, who already know this stuff, are so used to it that it doesn't always occur to us to mention such things anywhere!

Hi Phillip, have you tried the following guide:
https://docs.onion.io/omega2-docs/flash-arduino-dock-wirelessly.html

Hi Michael,

Yes, software installation wasn't an issue, my problem was fixed after pulling the power cord and plugging back in. After doing a sysupgrade it seems the arduino and omega got out of sync or something, totally pulling the power fixed the issue.

Phillip Walters

@Michael-Xie48 Yes I have, that's when I got that error.

frederic raducki

hello guys

i have a similar problem.
with the old firmware i was able to upload sketches on the arduino.
then i made the upgrade and like cusackph i was surprised that everything i've set-up before was gone

i made opkg install arduino-dock
then the Arduino IDE sees the board under the list of boards.

i was thinking that i have the ability to upload sketches back as before BUT
now i have an error i never had before on flashing (right after putting the password)

i also tried various press on MCU_reset button after password or plugin power off and on again .. but nothing changes

any toughts ?

frederic raducki

OK my bad.
i installed arduino-dock instead of arduino-dock-2 ...
doing opkg remove arduino-dock and then opkg install arduino-dock-2 makes the flashing work again.

the wiki should really inform beginners there are TWO different arduino packages

frederic raducki

and today this does not work ....

Flashing application '/tmp/sketch.hex' ...

ERROR, flash NOT successful
Flash complete!
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude done. Thank you.

frederic raducki

im starting to be fed-up ....
it worked yesterday with the latest firmware ...
now after i did a factory reset i can't manage to upload any sketch.
neither via Arduino last IDE nor manually.

this is what manuel install does with arduino-dock 1st version and arduino-dock 2nd version ...

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.

frederic raducki

any clue ? (up)

@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

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.

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

Phillip Walters

@frederic-raducki I think buying another Omega 2 is a bad idea. I've got a support ticket open over a month ago and have yet to receive a response. It's been "Being Processed" for 31 days now. Giving these guys more money seems like a bad idea until they prove they can sort this stuff out.

@frederic-raducki @rutayan-patro have you ever managed to get around this problem?

I am using arduino-dock (version 1) on Omega2+ and whenever I try to flash the bootloader I get AVR device not responding

I'm using avrdude: Version 6.1, compiled on Feb 3 2017 at 01:12:05

root@Omega:~# sh /usr/bin/arduino-dock flash bootloader
> Flashing bootloader...

avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


avrdude done.  Thank you.

Yes, because those connections are really missing on the first version of Arduino Dock.
Arduino Dock 2 has got an ICSP / ISP programming interface.
So you should build something similar circuit to burn a bootloader into the ATmega of a version 1 Dock with Omega2.

Venet

Thanks @György-Farkas

I'm new to arduino, so does this mean that I cannot use the arduino-dock (v.1) with Omega2+?

Is there any way to access GPIO pins of Omega2+ through arduino-dock?

György Farkas

@Venet
Unfortunately I have never seen - in reality - the version 1 Arduino Dock yet.
The Onion's schematic seems to be correct, except the representation of the reset button (SW2 RESET BTN).

So - according to that schematic - if you want to use Arduino Dock v1 with Omega2 you should

isolate pin_2 of Omega2 labeled 11 (ie. GPIO_11 / BOOTSTRAP_4) from its socket's pin
connect pin_2 of Omega's socket labeled VDD25 (ie. 2.5 V supply) to 3.3 V

(The "barbaric" solution: cut PCB trace(s) of socket's pin_2 and tie all VDD25 labeled points to 3.3 V with wires.)

I think this is the minimal mandatory modification.
Is this resolvable? Can you do this?

On version 1 dock Omega and the ATmega MCU can communicate via a serial connection and / or via I2C only.
So Arduino can not access Omega's GPIO pins directly.

ccs hello

Task 2
connect pin_2 of Omega's socket labeled VDD25 (ie. 2.5 V supply) to 3.3 V

is unnecessary. Omega2's own Net_Power pin (2.5V) pin internally is open-circuit.

This pin's original purpose is to supply DC bias for Ethernet magnetics (transformer) center tap.
For MT7688, it's not needed.
