Your APF51 board features a user switch connected to a GPIO pin (GPIO1_3). The driver gpio-keys translates GPIO events in key/button events.
Test
# cat /dev/input/event0
Then you should see weirds characters when pressing the user button of the apf51_dev board:
�,~~_�,}�}�3T,QToT6,TT�,�;��, � �
- if the test wiped out your console, you can get it back with:
# reset
