I am using ttyO0 as a serial console for another linux machine. When the BBB boots, it sends out messages out ttyO0 which is connected to another machines console. Since a getty is running and the messages get echo’d back, uboot reacts to those messages which stops the boot process…
So the bottom line is this:
How do I get uboot to NOT send out boot messages to ttyO0?
Here is a sample of the messages sent to ttyO0
