Problem setting up tty02 with new Angstrom Distribution 2013-06-06 on BeagleBone (white)

I just updated to Angstrom Distribution (BeagleBone) 2013-06-06 form the angstrom release that came with the unit.Now I find that I can no loner talk to tty02 as it does not exist, neither does the muxing work in the same manner, no /sys/kernel/debug/omap_mux.
If anyone can point me in the right direction I would appreciate it.

here is my mux config script as it was


echo 0 > /sys/kernel/debug/omap_mux/uart1_txd
echo 20 > /sys/kernel/debug/omap_mux/uart1_rxd
echo 1 > /sys/kernel/debug/omap_mux/spi0_d0
echo 21 > /sys/kernel/debug/omap_mux/spi0_sclk
stty -F /dev/ttyO2 115200 cs8 -cstopb
echo “uart 1 (TX):”
cat /sys/kernel/debug/omap_mux/uart1_txd
echo “uart 1 (RX):”
cat /sys/kernel/debug/omap_mux/uart1_rxd
echo “uart 2 (TX):”
cat /sys/kernel/debug/omap_mux/spi0_d0
echo “uart 2 (RX):”
cat /sys/kernel/debug/omap_mux/spi0_sclk
