Getting the beagle board to start the console with the new angstrom

Essentially the same procedure, but the serial console changed name from  ttyS2 to ttyO2 (A letter O, not a zero).  So, if you already have u-boot there for the second stage boot, you just stop the load process by hitting any key before boot, and then change the boot parameters:

First check your variables with printenv.

OMAP3 beagleboard.org # printenv

Then copy and paste the bootargs somewhere and replace the serial console. In my case it's:

OMAP3 beagleboard.org # setenv bootargs console=ttyO2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait video=omapfb:vram:2M,vram:4M nohz=off

Here I have already replaced the previous ttyS2 with ttyO2. Finally, you save your settings in nand to make them persistent by using saveenv:

OMAP3 beagleboard.org # saveenv
