To test the Ethernet ping functionality in Kernel.
Ethernet Switch / Hub / Router, Ethernet cable.
Make sure the network configuration & connection between Host & Target is established, connected to same switch / router.
Boot the board.
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

Patch card
• Check 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 - To export the gpio.
$ echo 133 > sys/class/gpio/export2 - To set the in/output of the gpio to the file direction.
$ echo in > /sys/class/gpio/gpio133/direction3 - To show the value
$ cat /sys/class/gpio/gpio133/value4 - Remove the patch card and give the below command
$ cat /sys/class/gpio/gpio133/value• Here GPIO value can be calculated as
VALUE = (gpio_BANK - 1)*32 + GPIO_Value

External LED should glow.
Boot the board from NAND/MMC. After booting check whether Expansion Header GPIOs are toggling or not.
To export the gpio.
$ echo 46 > /sys/class/gpio/exportTo set the in/output of the gpio to the file direction.
$ echo out > /sys/class/gpio/gpio46/directionTo set the gpio value to 1 (off) , indicating the GPIO pin to be set to a active low level.
$ echo 1 > /sys/class/gpio/gpio46/valueTo set the gpio value to 0 (on) , indicating the GPIO pin to be set to a active low level.
$ echo 0 > /sys/class/gpio/gpio46/valueHere GPIO value can be calculated as
VALUE = (GPIO_BANK - 1)*32 + GPIO_Valu

Set the date to board in kernel # date mmddhhminyyyy.sec (e.g 021811582020.12 ) is the syntax
$ date 012316442023.00Set the time and check by using below command to rtc.
$ hwclock -w -f /dev/rtcX
$ hwclock -r -f /dev/rtcX ( # here 'X' is available node numbers ).Reboot the board, wait few minutes. Check date and time both are same or not.
