@luz Yeah, true. I'll try some other regulators, and definitelly, I'll keep an eye on the berrydock (need to figure out, where to get a single board - I'm not the best in making double sided pcb's :)) ! Thanks for tip!

@luz I did use capacitors. Nothing helped. I've just ordered 3.3v power supply (I don't have zener diodes or linear regulators to build one now).
The strange thing is, that the same power sources are working fine with arduino, esp8266 and even raspberry pi. Can't believe, that Omega2 needs more power....

And I don't blame Onion. Shit happens. Many times I've had issues with firmware that was corrupt.

Answering to myself
I did test another power sources (including 12V/10A power supply as a source to the 3,3V voltage regulator).
Everything fails. It doesn't look like power, since raspberry pi 3 works like a charm on all of these power sources.

I'm a one step from throwing my omega2 through open window....

Need to try again then.
I've used so far:

1. USB-Serial powered from usb port of macbook pro
2. 3A voltage regulator (normally used to power a breadboard with arduino) and powered by power supply
3. same voltage regulator but powered by regular, 9V battery

It always stopped at 18-th second, unless I've selected "f" to get to the failsafe mode. Then it was stable (but no network etc).

p.s. I did not order the docking station as it breaks the whole idea of Omega2 for me - being small. Especially that I can use it with usb to serial (which I have) if I need to connect that way.

Hi

Exactly, same problem here. Connected Omega2+ via the serial-to-usb (I have no dock).
The led went on, then after these 18 seconds it went off and also the booting messages stopped....
I've got my Omega 2 days ago (if it helps to determine faulty batch or so), but only had time today to try it out...
