How to wire button for factory reset?
No. You can connect - the right pins !!! - directly.
Please let me know if it helps.
OK, gnd to rst and 3.3 vin to fw rst then press (gnd to rst )10 second then release right? while press reset button led on board will off ? and after 10 second led on board keep blinking am I right?
GND to GND
3.3V to (VIN --- 3.3V)
BUTTON_1 to (VIN --- 3.3V)
BUTTON_2 to (38 --- FW RST)
Turn on Omega and during the boot time press the BUTTON more than 10 seconds.
I am fairly sceptical.
I think nothing happen when i pressed button, so now i bought usb to ttl with CP2014 chip and connected to omega and computer by using 4 pin (i use PuTTY)
omega2+ ------- usb
vin --- 3.3 v
gnd --- gnd
tx0 ---- rx
rx0 ---- tx
result is blink these :
Board: Onion Omega2 APSoC DRAM: 128 MB
relocate_code Pointer at: 87f60000
flash manufacture id: c2, device id 20 19
find flash: MX25L25635E
all the time . what happen to it?
here is video clip link : https://www.youtube.com/watch?v=lLD7kF-zbLI
You must not connect the 3v3 of the USB serial to that of the module, only the ground and data lines.
The 3v3 power to supply the Omega will need to come from something with a far higher current capacity than the auxiliary output of your serial converter.
Hello @Chris Stratton
I'm confused ,Does the only 3.3v one line from other source will power Omega?
I think 3.3v and gnd should come from the same source in order to power omega on, or i missunderstood something.
Could you write a schematic please.
sorry for my English ,i'm not good at English. Hope you understand me.

@Ketsayay-Choohirun You have an insufficient power problem. You can use another stronger 3.3 Volts power source with the Omega and have a serial connection. To also use the USB TTL unit connect together all three ground wires then connect only the USB TTL Rx wire to the Omega. DO NOT connect the USB TTL 3.3V wire to the Omega - that WILL damage the USB TTL unit.
I got it ,the result below and what should i do next?

Ok i got him back ,i only have Omega2+ ,so i decided to do this:
Thank you very much for helping me
@ Ken Conrad
Do not forget a huge thanks to @Colt-Burns.
@György-Farkas But now i have some problem when i connected to power supply led on board keep solid about 5 sec and keep blinking all the and when it connect to network and after about 30 sec and turn off,what's wrong with my omg2.

@Ketsayay-Choohirun You are welcome. Probably nothing is wrong with your Omega - probably you have a power problem. Long thin jumper wires with loose connections at the Omega's pins will cause a dip in the power, just as the Omega needs more power (at least .25A at 3.3V) to turn on the Wifi.
You can use your serial connection to follow the boot progress so we can see when in the boot the Omega is halting.
