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.
echo 77 > /sys/class/gpio/export
echo out > /sys/class/gpio/PC13/direction
echo 1 > /sys/class/gpio/PC13/value
echo 0 > /sys/class/gpio/PC13/value
echo 1 > /sys/class/gpio/PC13/value
echo 0 > /sys/class/gpio/PC13/value
Expected o/p
[email protected]:~# echo 77 > /sys/class/gpio/export
[email protected]:~# echo out > /sys/class/gpio/PC13/direction
[email protected]:~# echo 1 > /sys/class/gpio/PC13/value
[email protected]:~# echo 0 > /sys/class/gpio/PC13/value
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.

Test Case 1 (Ping Test)

1. Make sure the network configuration & connection between Host & Target is established, connected to same switch / router.
2. Boot the board with NOR/MMC.
3. Before the ping test for Ethernet in Linux,we need to set the ip address by using below command on the target board. Make sure both the Target and Host are in the same sub-net
$ ifconfig eth0 192.168.1.11 up
4.Next ping to your host ip address by using below command.
