  • Kernel version：Linux-4.1.15
  • File system：L4115-fsl-image-qt5-myimx6a9.tar.bz2

Preparation before test

1）Please connect following the path of 《Linux fast boot manual》->“Linux fast boot” -> “device connection”.

2）Please boot following the path of 《Linux fast boot manual》->“Linux fast boot” -> “device booting”.

Test item

Network inferface test

MY-IMX6-EK200 support two 100 Mbps ethernet interfaces.

Interface property

Eth0 Interface position：P4 Eth1 Interface position：P3

Test method

1）Configure computer IP
Set wired network card IP of computer as 192.168.137.99

2）Eth0 connect test
Connect lan line: connect “eth0”on evaluation board with corresponding wired network card interface on computer with lan line.
Note: check jumper cap to ensure it is attached.

  • Set evaluation board IP：
# ifconfig eth0 192.168.137.81
  • Execute test command：
# ifconfig eth1 down 
# ping 192.168.137.99 -c 2 -w 4
  • Observe test result：system will output message like following:
  
PING 192.168.137.99 (192.168.137.99) 56(84) bytes of data.
64 bytes from 192.168.137.99: icmp_seq=1 ttl=128 time=0.811 ms
64 bytes from 192.168.137.99: icmp_seq=2 ttl=128 time=0.324 ms

--- 192.168.137.99 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.324/0.567/0.811/0.244 ms
  • Test result：“0% packet loss”represent test passing.

3）Eth1 connect test
Connect lan line: connect “eth1”on evaluation board with corresponding wired network card interface on computer with lan line.
Note: check jumper cap to ensure it is attached.

  • Set the second network port IP:
# ifconfig eth1 192.168.137.82
  • After setting, the system will output the working status information of the second network port:
fec 20b4000.ethernet eth1: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=20b4000.ethernet:01, irq=-1)
IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
fec 20b4000.ethernet eth1: Link is Up - 100Mbps/Full - flow control rx/tx
IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
  • Execute test command：
# ifconfig eth0 down
# ping 192.168.137.99 -c 2 -w 4
  • Observe test result：system will output message like following:
  
PING 192.168.137.99 (192.168.137.99) 56(84) bytes of data.
64 bytes from 192.168.137.99: icmp_seq=1 ttl=128 time=1.54 ms

--- 192.168.137.99 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 1.546/2.792/4.039/1.247 ms
  • Test result：“0% packet loss”represent test passing.

# echo 1000 > /sys/class/leds/led-timer/delay_off
  • Change the led-timer (D9) lighting time 
# echo 2000 > /sys/class/leds/led-timer/delay_on
led-default
  • The led - the default (D7) 
echo 0 > /sys/class/leds/default/brightness
  • Keep led-default (D7) on
echo 1 > /sys/class/leds/default/brightness
led-gpio
  • The led - gpio (D10)
echo 0 > /sys/class/leds/gpio/brightness
  • Keep led-gpio (D10) on
echo 1 > /sys/class/leds/gpio/brightness
