@WereCatf Where are you from, maybe i can take one from your hands?

Or you can use them to master the black art of smd

I think this topic should be a sticky.
With the next batch kickstarter/indiegogo users coming I forsee a lot of can't connect/wifi/power topics, this can be a (help) topic for user facing power problems.

When I received my Omega2+ I had the problem that after 20 seconds the led went out.
I used the recommended lm1117, breadboard and wires as power supply.

After some advice on this forum, i shortened the wires from 20cm to about 5 cm each and I added a 470uF 16v Capacitor.
I finally saw the Wifi Acces point in windows so i:

Connected to Omega-xxxx (default password 12345678)
Went to 192.168.3.1 and run the setup wizard.
After setup, i did a browser refresh and immediately updated the firmware in the settings panel.

Hi all,

I am making a pinout for the pads on the bottom, hoping to find some extra pins we can use.

Bottom pads

There are 2rows x 25 pads = 50 pads on the bottom (See blue text on image).
The headers + SD Card expose 2x16 + 8 = 40 pins.
So we have 10 extra pins to discover.

I already found a lot, but still missing some, I am hoping someone (maybe onion themselves) could help me identify the missing pins.

I made a sheet here:

Bottom Pinout scheme

J Tech

btw any idea how different pins can be assigned to the same function?
What would happen (if even possible) if you changed all pins to the same function?

For example, GPIO#46, GPIO#19, and GPIO#15 can all be assigned to PWM_CH1.

Thank you for the great info, I changed the image accordingly. (groups between parentheses and gray are possible groups when enabled in omega2-ctrl utility)

The datasheet helped me a lot to figure out and understand some more about the Omega2.
I tried to figure out the pins on the bottom of the Omega2, to see if it was placed for factory programming, debugging or it exposes other pins that are useful. (still haven't got them all)
Have a look: BOTTOM PINS

The omega2-ctrl utility is indeed like the Linkit Smart, it would be better to remove the options that are not relevant, I think they are only confusing.
I hope they accept your pull request or at least show a sign.
They should be lucky and embrace helpful people. :angel_tone2:

Does anybody know which group contains which pins?
I already added a few to the attached image, please confirm and add if you can.

Alright, guys thanks for the fast feedback.

I hope people with this problem will check their power supply first and get their Omega running.

Happy Inventing

J Tech

@ccs-hello It is connected the same way as described in the Omega2 manual and which Onion recommends.

Unfortunately, I can't test if this will solve the problem because mine is (fortunate for me) working now.
Maybe other people with the same issue can try using shorter wires or even create a simple PCB with the lm1117, getting rid of the breadboard.

Anyway, thanks @css-hello for helping out.

J Tech

@ccs-hello

USB-serial connected via (Three wire) Tx, Rx, and Gnd.

The lm1117 based circuitry is created on a standard breadboard.
Filtering caps, started with 10uf both sides.
Increased output cap to 22uf and later 47uf.
Input voltage: 9v 1A, 12v 2A.
Using 24 AWG Dupont wires 20cm length to connect it all.

I am aware the Omega is very picky about the power supply, this setup must be more than enough to power the Omega.

To me it looked like the USB-serial converter triggered something enabling the AP for first setup.
After i removed the converter to get past the EEPROM:Read from [factory] offset 0x0,length 0x400. part, all works like it should.

I can now boot with or without the converter, AP working, Busybox, Connect to cloud etc.

@Jae-Turner Using the serial connection will surely help you to see what is happening while booting.
Make sure you use a good 3.3v supply capable of delivering the required/recommended power. I hope you get it working.
If you do, please tell us here how you got it working.

https://community.onion.io/topic/1082/help-omega2-not-working/32 here you can find people with similar issues and solutions.

J Tech

That doesn't quite explain why using the recommended lm1117 and even higher rated regulators (with and without caps) didn't boot the Omega correctly.
Only after I connected the serial converter to the Omega it booted correctly and I could finish the setup.

After that i had to remove the serial converter to get it past "[ 16.965024] EEPROM:Read from [factory] offset 0x0,length 0x400."
and get the AP back.

Now all is working fine with the same power supply I used before it all worked.

J Tech

Found a topic with the same issues:

https://community.onion.io/topic/1082/help-omega2-not-working/32

Not sure what happened but after I disconnected the USB to serial converter all is working now.
It surely wasn't the power supply.

So in short:

Omega first boot --> after 20 seconds led off --> nothing
Omega Connected to USB converter -> Omega AP visible and able to connect via 192.168.3.1 --> Finished setup -> Stuck at EEPROM:Read from [factory] offset 0x0,length 0x400.
Disconnected Serial converter -> Omega Works.
Updated Firmware from 0.1.5 (b130) --> 0.1.10 (b160)

Hope this was just a little hiccup

Hi All,

I just received my Omega2+ and started using the manual, I powered the onion and the amber led came on for +/-20 seconds then turned off and..... No Omega-**** AP.... No blinking...nothing.

So i tried different ways to power the Omega (different lm1117, Arduino Uno, breadboard power supply) and every time the led goes off after 20 seconds and then doesn't do anything. While booting current drawn is 190mA peak, 170mA average and when its stuck its stays at 69mA. The power supply I am using currently is capable of delivering 1A.

So after reading the forums, i tried to connect a usb-serial converter to see what is happening using putty.
After connecting the omega using the serial converter for the first time, suddenly I saw the Omega AP and connected using 192.168.3.1.
I connected to my home wifi and then it was stuck, so I rebooted.
It said that the Omega was up to date and I pressed Install IDE.
After that it was stuck again and i wasn't able to get the wifi network back again even after a few reboots.
Putty stilll works but it's stuck at: EEPROM:Read from [factory] offset 0x0,length 0x400.
