When you type ls /dev/ttyO* on your new BeagleBone, what do you get?? I assume nothing...
TI switched the default serial driver back in (??) from OMAP (ttyOn) to the 8250 driver, ttySn. I believe the rationalle is documented in the kernel source code for the driver and other places. You should be able to switch back to the old OMAP serial drivers with the later kernels, but you have to re-build the kernel... There are other posts on here (beagleboard.og) describing part of that procedure. Thanks!
