@Eric-Min Omegas possibly run warm but not hot, unless powered at more than the unit's rating of 3.3- 3.6 volts. USB power is 5 volts ... is your Omega in one of the Onion docks, or did you power it directly with that USB power source? If not sure, can your use a VOM to measure the voltage across Omega pins GND and VIN?
wifi is not booting i can not log in it's stuck at the screen that i posted
Again, until you solve the serial noise you are just wasting everyone's time - especially your own.
Without clean output you cannot determine what the actual stopping state is. The only clean output you posted was from a different device, not the problem device, so it is meaningless. Don't assume that power and serial solutions that work on one will work on the other, as you are in the domain of edge cases.
Without clean input you can't even know if there is an actual problem, or if noise inputs are being interpreted as a user request to halt the bootup and remain in u-boot.
Looks like your connection to Onion Community was lost, please wait while we try to reconnect.
