@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.
