@WereCatf I am having the exact same problem with my Omega 2+: wifi is gone, taking all connectivity with it. I only have a power dock, so there is no ethernet available.
As per this thread, I tried connecting a USB serial port to the power dock's TX1 and RX1 pins. I get no response from the Omega2+. I know that my USB serial connection is wired for 3.3V, and I know that the serial converter board works.
I am pretty sure that the button on the power dock is not a reset button, but a button to manually tell the PMIC (power management IC) on the power expansion board to start working, as per the PMIC data sheet. That would explain why pushing it for 10 seconds didn't do anything resembling a reset operation.
I did make a bit of progress though. To get around the lack of a reset button, try the following:
- remove the LiPo battery (if any was connected)
- power down the Omega via power switch
- insert a jumper wire between the RST and GND connections on the expansion board connector. This should act the same as pushing the reset button on expansion boards that actually have a reset button.
- power on the Omega
- wait about 10 seconds
- remove the jumper wire, allowing the system to boot
- wait for system to boot (flashing LED transitions to solid LED in my case)
At this point, I can now see the Omega2+ acting as a wireless access point again using its default SSID: Omega-XXXX.
Sadly, I cannot connect to the Omega via that access point. The authentication fails every time using the default password "12345678".
In addition, the serial port still doesn't work for me.
Am I missing something obvious here? It wouldn't be the first time...
