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 *U-Boot 2013.10-00016-g6adb529 (Feb 06 2014 - 14:54:24)^M^MI2C: ready^MDRAM: 512 MiB^MWARNING: Caches not enabled^M* *NAND: 0 MiB^MMMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1^M*** Warning - readenv() failed, using default environment^M^MNet: <ethaddr> not set.
