@György-Farkas said in Omega2+ boot problem:

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.

Why?

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.

I have an expansion dock, connected to USB port of my desktop.
Yes, I don't know version of firmware
In next log I press f and hit enter and nothing happens.
For falesafe mode I hit reset key.
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.

When I turn on Omega holding reset, U-Boot doesn't give me 40 sec to make a choice to reflash from USB stick.
Also, I can't use busybox, it not respond to commands like "firstboot" or "mount_root".

I have a problem with my Omega2+. It can't finally boot. I have, already wrote about this problem in this topic
I think, that I used bad power supply, and data in the flash corrupted. Here is log for normal boot:

I can't flash new firmware from USB stick, because I can't make a choice in U-Boot menu. And Omega does not boot properly, WI-Fi does not start too.

I have the same problem. Firmware is 0.1.10-b160. Also can't start flashing new image from u-boot. When I press reset button, u-boot didn't wait for 40 sec and start to load kernel.

Hold Reset button for more options *

You have 40 seconds left to select a menu option...

Please select option:
[ Enter ]: Boot Omega2.
[ 0 ]: Start Web recovery mode.
[ 1 ]: Start command line mode.
[ 2 ]: Flash firmware from USB storage.

Option [
Boot Linux from Flash.
