Why won't my Omega stop blinking?
-
@Douglas-Kryder I have the expansion dock but its light is off, it is just the omega 2 that is blinking. I also have a relay expansion on the expansion dock incase that might be part of the problem. My device is connected through a wire connecting the expansion dock to my computer. Also, where is the reset button (just to make sure)?

@Douglas-Kryder I have tried the factory reset but once the omega is on, the light remains solid for a couple second and then still continues to blink.

@Lucia-Touma since you have the expansion dock you can set up a serial terminal to sorta watch what is happening at the boot. plug in a usb cable that has micro b male into the micro b female receptacle on the board and then plug in the usb a male to a computer with a usb a female receptacle. then open a terminal app like putty or minicom, etc. then read these pages . now, i am thinking you may have a damaged bootloader, but fist try the serial device at boot to see if you can get any info on the state of the omega. make sure that you have all the necessary drivers installed to obtain a serial connection.

How can I reset to factory my omega2 if I don't have the expansion board?

@Jaiber All the reset button does on the expansion is to pull the RST pin on the Omega2 to GND. You can attach a button or a jumper cable on the pin yourself. (https://docs.onion.io/omega2-docs/omega2p.html)

No.
If there is RESET BUTTON (a normally open momentary push button) on any Omega2(+) Dock it pulls up the FW_RST pin to High (ie. 3.3V VIN).

@György-Farkas Good catch, didn't read docs well enough

For example briefly:
-
by SW
Connect Omega with ssh and type these commands:
firstboot -y
sync
reboot -
by HW
Connect the FW_RST pin to the 3.3V VIN pin temporarily via a push button or carefully with a piece of wire.
There are short press/connect (Reset) and long press/connect (Factory Reset).

Good luck!

@Lucia-Touma Did you add anything to /etc/rc.local?
I just discovered that if /etc/rc.local does not complete during startup (e.g. you launch a script before the 'exit 0' statement and don't background it) then your O2 led blinks forever....

@cas
Yes, if your script includes an infinite loop or never stops for other reasons the boot process will not end and the led kepps blinking.You can tell the rc.local file that this script will not end by attaching an & behind the command.
E.g.: python /path/to/you/file.py &
