  Any hope for a PPS output from the GPS receiver? The Quectel website requires a login to see the modem datasheet. Any hope for an OpenWRT PPS driver via an unused GPIO? I really love the Omega, but software support other than standard OpenWRT packages and high level language interpreters like Python is really lacking. I'm looking for GPS with accessible 1PPS and integration with ntpd and audio capture at 48 or 96kHz. From my understanding there is only one serial port and that is used for the console, so the only way to interface GPS would be a USB serial port adapter, unless this modem provides NMEA output via a built in USB to serial port adapter.

  Does the modem connect via USB of some sort?

  I had some issues with the recovery process on 2 of my 2+. It seems the reset to factory firmware takes a very long time on these units. Not sure why and didn't investigate, but I just let them run and went out for a couple of hours and they were good when I rebooted them.

  The most common problems I have always come back to the power source.

  First time posting on the Onion Community... Hello, hello.
  The Omega2 has seemed very promising as a fast track to product development and I commend the efforts of the Team and Community.

  I am also looking to get i2s audio functioning on an Onion Omega2. I am working on a product where we had been considering the LinkIt Smart 7688 as an embedded solution, but it suffers from a lack of support when it comes to running more modern OpenWRT with i2s functionality, similarly unsupported by the larger OpenWRT community.

  I was hoping that the i2s functionality on the Onion Omega2 would make this a clear alternative to the LinkIt Smart 7688, however it seems that they both lack the attention to get the feature running.

  All of this is to say that I just wanted to add my voice and product needs around a functioning embedded linux solution that has out of the box i2s audio support.

  I've scraped together whatever information that I can to attempt to get i2s functioning by way of building my own custom firmware with ALSA enabled and DTS files altered only to result in:
  A) a custom built firmware with almost functioning i2s (ALSA detects a "card") but no proper playback
  B) a custom built firmware with no functioning i2s even though I seem to have all of the puzzle pieces in place
  C) a custom built firmware that crashes on boot

  I'm really not sure what's next to experiment with, but any input would be greatly appreciated on either a path towards a solution running i2s on the Omega2, or suggestions on an device alternative that is in the same price range but is committed to supporting i2s audio.

  Thanks,
  Colin

  Im a noob to all of this and linux... I began the getting started tutorial and opted out of the cloud and did the firmware update and after it finished downloading the firmware it immediately my onions green led started to flash really fast. since I have not been able to find my onion in my wifi list to sign in to it. Any ideas as to what I need to do to fix this?

  @cas several years ago a google engineer released some review on usb-c type plugs/cables that revealed just how many of them were faulty, seemed incorrect/bad resistors being most common. google engineer Benson Leung published a list of ok cables/adapters on his google+ page which ceased to exist recently and someone else created this posting of his findings,
  https://bensonapprovedcom.wordpress.com/
  google sells some models on their store but they are pricey. at least much more than in 2016. i bought off that list on amazon and spent ~$12US for a kit that had a usb-c male to usb-a male cable [for attach a android phone to win 10 box] plus a usb-a female to usb-a female to create the needed usb-a female host port for OTG. ebay has some also, usually cheaper.

  @Jake-Fulford did yo manage to create a product grade solution with the Omega? I put my project on the back burner for a while but now I am back at it. I guess some external watchdog + power cycling circuit is needed but I am just wondering if you thought of something.

  @Filipe-Madureira ,

  I also had been facing same problem since last year. and have not got proper solution.
  There is alternate solution through which i get out of this issue and that is power supply.

  change the power supply Pin-board, that means plugin omega somewhere else from where you get proper supply (i got it by using this). or change power supply mode through USB directly from your computer usb port. or use a 3-pin adaptor/plug (i.e. which adaptor have 3 pin).

  Hope this will resolve your issue.
  i know this is quite not proper technical solution but beleive me i got it by using point no 1 and 3

  I tried with 3.3 and 5v, I tried also the same screen with an arduino uno and there wasn't any issue (the sketch printed and recognized the screen at the default pin as should be).
  I tried with another i2c screen that I have and not worked (I had the arduino starter kit that doesn't include the lcd screen).

  I am not an expert but as far as I can see it's basically OpenWrt with some additional Onion packages installed and of course the wi-fi driver. The additional packages generally are to support Onion specific hardware and wed pages for initial setup and Onion apps for the web interface.

  For me it is a smart choice. They use a standard OpenWrt build and just add a few things to add the additional functionality required to support their device and peripherals, it's not a complete fork of OpenWrt for some kind of vanity project.

  @Nikolay-Vetrov Yes, upgrade to the very latest available firmware: oupgrade -l -f and the ledchain kernel module will work right away.

  That's actually what controls the notification LED on the Omega2 Pro

  @ccs-hello Thank you, this worked perfectly. I can't solder very well, so I used shorter wires and hooked up 2 220 uf capacitors. It booted like a charm.

  I ran into this problem a couple of weeks ago and just now had time to dig into it a little more, I found a thread that provided this solution:

  run
  ar -rc /usr/lib/libpthread.a
  to create an archive file that is missing.

  Also, for serialport specifically it looks like someone has tackled that:

  Hi Steven,

  I had the same issue running Docker on my Mac and trying to compile the latest Github version...

  The only fix I've found is to remove Mosquitto using make menuconfig. You will find it on the Networking section so you can remove it and not include it in your compilation

  @Enrico-Trevisanello said in Omega2 and LUCI:

  I was connecting to the Omega through the IP address of the ethernet wan network interface and not the br-wlan 'access point' interface. Is there a way to get LUCI working on that one?

  It should be possible by adjusting firewall port forwarding settings.
  Another way is tunneling HTTP over SSH: https://openwrt.org/docs/guide-user/luci/luci.secure

  @György-Farkas yes I started experimenting with a LED strip I have which uses the WS2812B LED. Dimming these things smoothly is my current challenge.
