Test item

Lan port test

  • MYZR-SAMA5-EK200 support dual lan port(one Mbps ethernet lan port,one Gbps ethernet lan port).

Test instruction

  • The first Ethernet port is located on the front side of the base plate "J3", and the second Ethernet port is located on the front side of the base plate "J2".

Test method

1）Test the first ethernet lan port(Mbps ethernet lan port).

  • Connect lan line：connect “J3”on evaluation board with computer lan port through network.
  • Set computer IP：set computer lan port IP as 192.168.18.18.

  • Set the evaluation board IP:

＃ ifconfig eth0 192.168.18.81 ＃ configure the eth0
＃ ifconfig eth1 down

  • Execute test command

＃ ping 192.168.18.18 -c 2 -w 4 ＃ send ICMP to HOST

  • Observe test result：system will output information like below：

--- 192.168.18.18 ping statistics --- 2packets transmitted, 2 packets received, 0% packet loss

  • Test result：“0% packet loss”represent test passing.

2）Test the second Ethernet port (Gigabit Ethernet port)

  • Connect lan line：take out lan line from the first lan port then plug in “J2”on evaluation board，another end of lan line is kept in connection with lan port of computer.
  • Set computer IP：set computer lan port IP as 192.168.18.18（if the setting was already done then go direclty into next step).
  • Set the second lan port IP：

＃ ifconfig eth1 192.168.18.82 ＃ configure the eth1
＃ ifconfig eth0 down

3)After the setting system will output working condition of the second lan port, as below:

macb f0028000.ethernet eth1: link up (1000/Full)
  • Run test command：

＃ ping 192.168.18.18 -c 2 -w 4 ＃ send ICMP to HOST

  • Observe test result：system will output the following message:

LED（GPIO）test

LED（GPIO）definition

There are 4 LEDs on the base board of MYZR-SAMA5-EK200,details as below:

silk screen CPU pin LED property application
D12 PE1 default brighten after booting of kernel
D13 PE2 heartbeat flash when CPU is in working
D14 PE3 gpio user control output
D15 PE4 timer Timer demonstration

Led-default test

1)Led-default corresponds with D12. when booting of system is completed,the LED is brightened defaulty,which is ususally ussed as power indicator,in other words,brightenness of the LED represent a switching on of devices on the condition that user doesn't control the LED.Of course,user can control on and off of the LED,in this case,there is not any relation between on/off of the LED and working condition of power source.
2)Control command as below:
＃ echo 0 > /sys/class/leds/default/brightness
＃ echo 1 > /sys/class/leds/default/brightness
MY-SAMA5 Linux-3.18 2.4.2.1.png

led-heartbeat

Led-heartbeat corresponds to D13. After the system is started, the LED flashes and the status of the LED indicates the operating status of the CPU. Blinking indicates that the CPU is working properly. If the indicator is steady on or off, the CPU is not working properly (that is, the CPU may not work).

led-gpio test

1)Led-gpio corresponds to D14. After the system is started, the LED is kept off by default. After entering the system, we can control the LED's on and off by commands.
2)The CPU pin used by the LED is PE3, and its properties are represented in the system by the relevant files in the /sys/class/leds/gpioE3/ directory.
3)Controling commands as below:
＃ echo 1 > /sys/class/leds/gpioE3/brightness
＃ echo 0 > /sys/class/leds/gpioE3/brightness
MY-SAMA5 Linux-3.18 2.4.4.1.png

led-timer test

1)led-timer corresponds with D15,this mainly demonstrate GPIO as timer signal.
2)Its property is represented by the relevant files under directory of /sys/class/leds/timer in the system.
3)We can set dealy to control holding time of high/low electrical level of GPIO
4)Controling commands as below:
＃ echo 1000 > /sys/class/leds/timer/delay_off
5)Control holding time of low electrical level via delay_off,1000 means 1000ms.
＃ echo 2000 > /sys/class/leds/timer/delay_on
6)Control holding time of low electrical level via delay_on,2000 means 2000ms.
7)After execution of the above two commands,the result: 1 second after D15 goes out,then lit for 2 seconds,cycle this way.
