+ # 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

-  - 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.
