@Ankit-Rana I tried to reply for this "Omega 2 can't complete booting process!!!" and this "Omega continously Booting ..." statements.
Later you wrote
Omega 2 can't complete booting process!!!
but still the LED is blinking for some time and again it continue, omega complete booting process.
"Omega 2 can't complete booting" vs "omega complete booting" - this is some contradiction.
And I don't fully understand what about the amber OMEGA LED.
You have a USB-to-3.3V TTL serial converter module.
You have already made a Serial Console connection (RX0, TX0, GND --- your module Tx, Rx, GND --- USB port of your host PC --- PuTTY). Omega continously Booting cant find access point
Look at the output of the Serial Console to see what's going on.
my Omega2+ will "shut down". I can't access the Wifi AP and the LED is off.
If you find your board in the state you described again, before you do anything with it try probing the SPI lines with a logic analyzer. If you see activity it means that your Omega2+ suffered an unexpected reboot and the SoC primary bootloader is trying to load U-Boot using 3-byte addressing, but the SPI flash is still configured to use 4-byte addressing. (refer to Omega2 reboot for more info on this issue). If this is the case you have to power-cycle the board in order to get it to boot again (which resets the SPI flash addressing to 3-byte mode)
@kevin-Wagner Most probably the USB port of your computer can not provide enough current.
Try another USB port, another computer or try to power your Omega with a good 5V 1A (min 500mA) (wall) adapter.
According to the second log file of the other topic you was able to enter into the failsafe mode. You should hit the f key and hit Enter fairly quickly.
For failsafe mode I hit reset key.
Omega doesn't accept any command via terminal, I do not know why this happens. I have only one way to enter to failsafe mode, press "reset" button.
Also I think, that Omega "tells" me about this problem:
ash: can't access tty; job control turned off
I try minicom, PuTTY and Arduino IDE terminals to connect to Omega2 serial console, try to use LF, CR and CR+LF to enter a commands.
Check the host side of your serial Console connection in some way please. As you know LF (0x0a) is the end of line in Linux but there isn't any problem if you use CR+LF ( 0x0d 0x0a) here.
I connect Omega to PC by PL2303 adapter and external power supply and watch the same behavior.
If I put omega2-ctrl gpiomux set pwm0 pwm in a script.sh file and run it then I get the following message:
unknown group/function combination.
Does anybody has an idea how to resolve this issue?
The LD1117S33 (if authentic) needs minimum of input 0.1uF and output 10uF capacitors.
Also, do not use thin power supply wires. I recommend minimum of 22 Ga.
Okay, I added 47uF and 220uF capacitors to my circuit (on Vin and Vout of the LD1117 respectively) and swapped all the wires for 22 gauge. And... it works! Boots up completely and was able to setup wifi through web config and so on. Thank you!

I've got an environment setup on a io board , that I would like to switch the linux console port from ttyS0 to ttyS1. I wasn't sure if that is done in /etc/inittab or in one of the system config files ?
I have an omega2.
I'm not sure how Oninon's kernel does it, but in Mediatek's, Linux detects which UART U-Boot activated and uses that.
You could override this in the kernel if building it from source - I had to as I turned on a second one in a custom U-Boot, and Linux was then not using the one I wanted.
