BeagleBone Command helper doc

BB_helper

To list the USB connections

    ls /dev/ttyUSB*

To start a USB screen session with the BB
    sudo screen /dev/ttyUSB0 115200

To Eject a mounted BB
    sudo eject /dev/sdx - where ‘x’ is the id for the device to exject

On BB, run to see loaded modules change after host computer eject
   lsmod - to see the loaded modules... like ethernet

On host, view the mounted devices (should show BEAGLE_BONE)
mount - to show the mounted devices on the host computer

ssh root@10.0.1.16

location of gpio pins
/sys/class/gpio

First Setup the pin
LED Pin
Pin 12 in P9 Header - GPIO1_28 change to Mode 7 to get it to GPIO60 (1_28) 
gpmc_ben1
/sys/kernel/debug/omap_mux# cat gpmc_ben1 
echo 7 > gpmc_ben1 to change the mode to mode_7 (if it is not set that way)
Then export the pin
cd /sys/class/gpio
echo 60 > export      
to  export the pin
cd /gpio60
echo out > direction
echo 0 > value (LED off)
echo 1 > value (LED on)

Button Pin
Pin 25 on Pin9 Header - GPIO3_21 change to Mode 7 to get it to GPIO117 (3_21) (3*32 + 21)
/sys/kernel/debug/omap_mux mcasp0_ahclkx

see gpio settings 
cd /sys/kernel/debug
cat gpio
