 From the u-boot command prompt, first display the env variable console 
with the printenv command.  It is probably currently set to 
ttyS2,115200n8.  Use setenv to change console to ttyO2,115200n8, then 
save it with saveenv.  Here is how it should look:

Overo # printenv console
console=ttyS2,115200n8
Overo # setenv console ttyO2,115200n8
iRobot # saveenv
