-# Wire the circuit as follows: 
+# Wire the circuit as follows:
 # 1) connect anode (+) lead of LED to P9.12 pin
 # 2) connect cathode (-) lead to 1K Ohm resistor
 # 3) connect that 1K Ohm resistor to DGND (P9.1)
+#
+# NOTE: the pin mode can be verified with the command line
+# utility config-pin on the BeagleBoard.org Debian image
+#
+# To verify the pin is in GPIO mode:
+# debian@beaglebone:~$ config-pin -q p9.12
+# P9_12 Mode: gpio Direction: out Value: 0
+#
+# To set pin to GPIO mode:
+# $ config-pin p9.12 gpio
