Description
To test GPIO let us use the On-board LED on RuggedBoard. For this demonstration let's use LED_1 which is connected to GPIO PC13 (Refer hardware manual for more information).
Required Hardware
RuggedBoard-A5D2x
Test Case:
1.Boot the board from NOR/MMC. After booting check toggling of USER LED.
Step 1:
Type the following commands in a sequence to toggle led.
1
echo 77 > /sys/class/gpio/export
2
echo out > /sys/class/gpio/PC13/direction
3
echo 1 > /sys/class/gpio/PC13/value
4
echo 0 > /sys/class/gpio/PC13/value
5
echo 1 > /sys/class/gpio/PC13/value
6
echo 0 > /sys/class/gpio/PC13/value
Copied!

Try the above steps again replacing 77 with 81 & 83 respectively to toggle other two LEDs present on the board.
You can use remaining two user LED or any GPIO PIN mentioned in the Hardware manual with the same method. In case of any doubt post your detailed question into the RuggedBoard forum.

Description
To test the digital input pin on the carrier board.
Required Hardware
phyCORE-A5d2x System on Module
phyCORE-A5d2 Rugged Board
USB cable
Patch card
Step-by-step guide
Boot the board from NOR/MMC
Carrier board having 4 digital input pins on P5 connector.Fifth pin of P5  connector is ground.
After completion of board booting, connect the one end of patch card to first pin of P5 connector and other end to input voltage pin.
Give the below commands to test the digital inputs.
1
$ echo 84 > sys/class/gpio/export
2
$ echo in > /sys/class/gpio/PC20/direction
3
$ cat /sys/class/gpio/PC20/value
Copied!
Remove the patch card and give the below command
1
$ cat /sys/class/gpio/PC20/value
Copied!
The  value of digital pin is changed one to zero.
Meanwhile we can check the rest of the digital pins on P5 connector.Please have a look on below expected output for all digital input pins on P5 connector.

Description
To test the digital output pins on carrier board
Required Hardware
phyCORE-A5d2x System on Module
phyCORE-A5d2 Rugged Board
USB cable
External LED
Step-by-step guide
Boot the board from NOR/MMC
Carrier board having 4 digital outpins on P6 connector.Please refer the schematic to p6 connector pins.

After booting connect the External LED postive to 5th pin of P6 connector  and other end to Ground.
Please give a below commands and observe the led status.
1
$echo 97 > /sys/class/gpio/export
2
$echo out > /sys/class/gpio/PD1/direction
3
$echo 1 > /sys/class/gpio/PD1/value
4
$echo 0 > /sys/class/gpio/PD1/value
