@Daniel-Andrade It's an excellent idea to have the Omega pins available for customized use, and on standard headers to boot.

RE: Wasted Topic response
Dear guest! I understand your frustration. User's editing skills varies from people to people. However, some people just don't care and only want their own little problem fixed quickly and free, i.e. with little or no effort from the original poster. This kind of behavior is not very appreciated among the community. The advice is: show you are genuine, put some effort to learn, get your hands dirty, and help the helpers help you.
RE: help omega2 not working
Just like racing cars, fast engines rely on quality fuel. Slower microcontrollers are more flexible regarding their power supply input, but there are still limits in order for their internal timings to be met. When push comes to shove, manufacturers decide to provide their own power regulators, but they need to compromise on size, and boards become much bigger than the Omega(2)(+).
Kickstarter October Update
Kickstarter October Update:
A few of us have been living in Shenzhen, China for the last few weeks overseeing the manufacturing of the Omega2 and planning the logistics of actually shipping them out.
Wow! That's serious commitment (and the only way to go to insure Quality Assurance). I'm very impressed by Team Onion!
RE: Scripts and /etc/rc.local on bootup
@Costas-Costas The & at the end of a command is a request to run the command immediately in parallel (here, parallel to the boot process). This is the perfect technique for very long user made projects or script that runs continuously.
It's a bad idea to use & at the end of a
sleepcommand line because it will run in parallel, thus having no effect at all on your boot process.
RE: Scripts and /etc/rc.local on bootup
@Costas-Costas Any error reported in the system log files? Absolute paths to commands are needed in a system file. Maybe some of the needed system components are not fully loaded when you perform your request. Some people have added a
sleepcommand in the script to give the system a better chance.

RE: Documentation is incomplete
@Manuel-Godinez If you are not the type of person that go on a hunt for the bit & piece of information here and there, I recommend that you wait for the PROJECT BOOK announcement, so your mind is kept sane, and your Omega2 kept safe from permanent damages.
RE: Omega2+ console (browser GUI environment) applications not loading
@Alexander-Peace You may try yesterday's firmware build
omega2p-v0.1.9-b149.bin. Also, you may try a different browser. About the Web Console interface, consider it a bonus-extra-feature, and don't rely on it. It's not v1.0 yet. Also, use GitHub to report issues:
RE: SFTP on Omega 2+ [RESOLVED]
@jorgegarciadev This post from Kit may be of help to you:
Personally, I use the WinSCP program with the SCP protocol. This one works as is with the Omega2+'s SSH implementation (Dropbear).
[Tip] Switch the Omega to VERBOSE
So, your Omega(2(+)) doesn't work? What to do? This little piece, shielded by a metal plate may seem like a mystery, an impenetrable black box. Don't let that overwhelm you. The Omega is a little verbose devil... if you know how to listen. And do listen to it! You'll be rewarded with countless hours of spared debugging time.
If you are new to the Omega, go read the docs here:
If you have problems with the Omega, go read the guidelines here:
Don't be lazy! Don't be full of yourself! Don't skip it!
But first, something not (yet) mentioned in the docs, ground yourself and perform a thorough visual inspection of all hardware pieces that you receive. Look for non-aesthetic solder blob on the board. I personally found some. Pin solder weren't touching but they were too close for comfort, IMO. To fix that, I used a soldering iron with the pin over the heated tip of the iron to let gravity fix the solder blob. Also, perform this basic test to see if you have any short circuit between ground pins, power pins and the other pins. Statistics from my purchase, 33% of the Omega2+ were affected by solder blobs. I wouldn't say 'sloppy', but it's definitely disappointing. As, is there anything else wrong with those Omega2+?
So now, do you feel your Omega reaching out to you? Great! You are in the right state of mind. The secret is: get connected to the Omega's first serial port (labeled RX0 and TX0). By default, the port speed is 115200 baud. I use this command under FreeBSD:
cu -l cuaU0 -s 115200
Linux, Mac and Windows have their equivalent too.
You bought the Omega without a dock? Well, you know what you are doing, and you are good at it too. Read the docs for the relevant pins, and get connected. You purchased an Expansion Dock? Great minds think alike. It's the easiest way to communicate. You just need a mini-usb cable from the dock to your computer, and those cables are just laying around you doing nothing anyway. You got the Mini Dock instead? No problem! Its mini-usb connector provides the same communication functionality. I can't blame you to like things small. I do too!
If you have the other docks, tough luck, but do not despair. I'm promoting you to EXPERT LEVEL. The first Omega serial port is still available, but you'll need to solder three wires on it (RX0, TX0 and GND). Refer to the docs for the right pin numbers. Remember that it's a 3.3V level. You can build yourself a serial-to-usb circuit of your own, a RS-232 driver, or whatever you like, but do use the first Omega serial port. If not, it's just like driving blind. How long can you last?
RE: do_page_fault(): sending SIGSEGV to fast-gpio for invalid read access from 00000600
My proposition was to add a KNOWN ISSUES section in the docs so people wouldn't waste-time/pull-their-hair/risk-an-heart-attack to try features that aren't yet ready for the users.
RE: Power the Omega without board.
Clever marketing I would say, they want there Power Dock to sold to us. Which it will not be smallest and cheapest Linux server.
You are totally unfair on this one. Doesn't the 3.3V pin go directly to the SoC? If so, Onion has nothing to do with this particular specification. MediaTek, the maker of the MT7688 IC did.
Funny thing is voltage around > 3.8V it works for cuple of seconds and restarts.
About the Linkit (a close Omega2 cousin), MediaTek says: Requires a regulated 3.3V. If a higher voltage is used, the board will be damaged. So there you go! Don't go over 3.3V +- 10%. Read the datasheet!
