@Scruffy I wanted to chime in here on the repo question
The older firmware images can be found here: http://repo.onion.io/omega2/images/
This repository has all of the 0.1.x and 0.2.x firmware images (2018 and earlier).
The new repository is here: http://repo.onioniot.com/
We switched to that in early 2019 and it has all of the 0.3.x firmware images
@Lucas-Gozalvez Agree with @crispyoz, is there enough power available to the Omega?
Also, would be helpful to see if there's anything special about this specific wifi network. Please post the debug output from the wifi troubleshooting FAQ post if possible
@francisco-vieira Agree with @crispyoz it does look like the filesystem is corrupted on these units.
A few questions for you:
@vkusnayakuraga the onion community is generally for technical content.
your best bet for order related questions is the helpdesk. please be patient, the support team will get back to you as soon as they can.
Btw, I've edited your post to remove your email address as a spam reduction measure
@Carey-Capaldi Responded in the LVGL+micropython thread on getting mqtt running in micropython. Check it out here: https://community.onion.io/topic/4164/micropython-build-with-lvgl-for-omega2/6
This way will take up much less space than python3, pip, and paho-mqtt. Will also be a more straight-forward program 
Let us know how it goes!
Love the videos btw!
@Carey-Capaldi You can get mqtt (and a whole lot more) for micropython with the micropython-lib package.
Just updated the Omega2 Dash guide with a new section on installing micropython-lib
Let us know how it goes!
@Callum-Jones I'm not sure if anybody has already designed an enclosure, but if you're so inclined, you can use the board measurements to design your own.
See this post for info on where to find the board measurement files.
@tjoseph1 said in Orphan files?:
- You should not see the jffs2 "complete build" message twice.
Agreed, don't think you should be seeing this twice.
But assuming @Lucas-Gozalvez is using the correct firmware for his device (Omega2+ firmware for Omega2+, or Omega2 fw for Omega2, I'm not sure this type of patch will help.
We already define two different devices for the Omega2 (16MB flash) and Omega2+ (32MB flash) devices.
In general, for jffs2_build_xattr_subsystem messages (that only appear once per boot):
We see the same messages on a variety of devices, most of the time with different values for the dead, orphan or unchecked.
And we've observed that after a factory restore or sysupgrade with -n the numbers reset to 0.
Given that xattr looks to just be a way to add metadata to files, we're confident that it won't affect the operation of the filesystem or the device itself.

@tjoseph1 said in Many errors with Omega2 .. opkg segfaults, unable to upgrade firmware.:
Now, my question would be:
The latest FW avaiable at http://repo.onioniot.com/omega2/images/ is omega2-v0.3.2-b244.bin. I chose omega2-v0.3.2-b233.bin, since it was the one the "automatic upgrade process" picked. I am not sure why it selected that version of FW. Can I upgrade to b244.bin?
See http://docs.onion.io/omega2-docs/using-the-omega-updating.html
@crispyoz good suggestions, thanks!
updated to include both suggestions as well as a notes on contributing and using the onion-setup-build.py script
We've updated the readme in the Omega2 build system repo to better describe the process of customizing the firmware (and to link to external resources that go into greater detail).
Find it here: https://github.com/OnionIoT/source#onion-omega2--omega2s-firmware-build-system
We would love to get your feedback on the updated documentation: whether it covers everything that's needed, if it makes sense, what else should be added, etc
Let us know!
@arianmares Rest assured that when they get the information they're looking for, our support team will get back to you.
Please keep in mind that both Onion support and our fulfillment partner are generally operating with fewer staff than usual while dealing with a higher volume of requests due to Covid-19. Most logistics systems worldwide are still experiencing longer than usual delivery times for the same reasons.
If you're looking for an alternative way to order Onion products, I would encourage you to check out our distributors Mouser and Digikey. They're both well known for their quick and reliable shipping.

Submit a field report for a project you've made with the Omega2 Pro, Omega2 LTE, or Omega2 Dash and you'll get a chance to share your hard work with the Omega2 community and have a chance to win some great prizes!
Use the Crowd Supply submission form to submit your field report. Make sure to include a description of your project along with any supplemental pictures, video, or other resources.
If your project is suitable, it will be published as a field report on Crowd Supply and you'll get a $25 Crowd Supply credit!
And all publishable projects for each device received before September 1st will be entered into a random prize drawing:
Grand Prize: Omega2 LTE Global
2nd prize: Omega2 Pro
3rd prize: Expansion Bundle (NFC/RFID, ADC, PWM, Ethernet, Proto)
That's right, there's 3 of each prize to be given away.
We can’t wait to see what you’ve made!
@Radek said in How can I pass one GPIO pin to an other?:
Yes, this is what I actually tried to ask: how can i programmatically pass GND to those two pins.
I don't think connecting pins from Omega would do the trick as I need to pass GND.
For the moment the only idea I have is to buy relays but I would rather try to avoid it of possible
Instead of relays, try making a switch with a transistor. That way, you can use the Omega's GPIO as the control signal (set the logic level), but don't have to depend on the Omega to provide the current.
We used this method for the Omega-controlled MCU reset on the Arduino Dock 2:
@Modest-Polykarpovich great project!
@Modest-Polykarpovich said in [Manual] Connection TFT display ILI9341 (custom Dash):
Or download and force upgrade firmware (filename omega2dash-vX.X.X-bXXX.bin) via util sysupgrade from repo.onioniot.com. DIDN'T TESTED!
This should work assuming your TFT <-> Omega connections are the same as the Dash
@luz It should be possible to use the bootloader command-line to read the version + device info of the SPI flash chip.
@Moonshiner Yes, it's not in the DTS
If you want to make the change when the device boots, you can use omega2-ctrl to change the pin multiplexing. See the ephy group here http://docs.onion.io/omega2-docs/using-gpios.html#using-gpios-multiplexing
However, if you're using a more recent version of the bootloader, GPIO43 should be set to act as a GPIO by default. Learn more about checking your bootloader version, the bootloader changelog, and updating it here: http://docs.onion.io/omega2-docs/Web-Recovery-flash-bootloader.html
@Moonshiner These documentation articles should be useful:
http://docs.onion.io/omega2-docs/using-gpios.html#from-the-command-line
http://docs.onion.io/omega2-docs/running-a-command-on-boot.html
If you need the gpio to be a certain value as soon as the system gets power, then you'll need to modify the bootloader.
The bootloader is open source and available here: https://github.com/OnionIoT/omega2-bootloader
