   # BeagleBone Black User LEDs
   
   The four blue user LEDs on the BeagleBone Black are wired to GPIO1_21 through GPIO1_24. To control the LEDs from userland, set **gpio=YES** in rc.conf and add this to */etc/gpio.conf*:
   
   [[!template  id=programlisting text="""
   gpio1 21 set out USR0
   gpio1 22 set out USR1
   gpio1 23 set out USR2
   gpio1 24 set out USR3
   """]]
   
   After rebooting, the LED states can be controlled with [[!template id=man name="gpioctl" section="8"]].
   
   [[!template  id=programlisting text="""
   # turn the USR0 light on
   gpioctl gpio1 USR0 on

  - Growing the root file-system  
    - During the partitioning process, do not delete or format the  
      first MSDOS (FAT) partition, as this is what your firmware by default boots from  
      (unless you have prepared a boot partition on other media).  
    - For accident-free operation of resize_ffs, the filesystem it is supposed to grow needs to be either not mounted or at least not mounted for writing.  
      To do that for a root filesystem, reboot to single user, and at the prompt to enter the pathname of shell, press  
            return for the default (/bin/sh).  
    - At the # prompt, type  
   
         "disklabel -i ld0" and press return.  
    - At the partition> prompt type "A" and press return.  
   
            Adjust disklabel sector from 4194304 to 62333952 [n]?  
            Type "y" and press return.  
    - partition> prompt type "a" and press return.  
   
            Filesystem type prompt, press return to use the current value (4.2BSD).  
            Start offset prompt, press return to use the current value.  
            Partition size prompt, type "$" and press return to grow the  
            partition to use all available free space.  
    - partition> prompt type "W" to save the changes to the disklabel.  
   
            Confirm this choice by typing "y" at the Label disk prompt.  
            Type "Q" and press return to quit disklabel.  
    - At the # prompt (shell), type  
   
            fsck -fy /dev/rld0a  
            resize_ffs -y /dev/rld0a  
    - This may take a few minutes, be patient!  
   
            fsck -fy /dev/rld0a  
            mount_msdos /dev/ld0e /boot  
            reboot  
     - When the system comes back up, the root file-system will have been expanded to  
            fill the SD card.
