576Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
577 OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
578 2.6.35 linux-yocto-stable, be sure replace ttyO2 with ttyS2 above. You
579 should also override the machine SERIAL_CONSOLE in your local.conf in
580 order to setup the getty on the serial line:
