[[文件:MY-IMX6-ek140p L41115 1.1 .jpg|520px]] 
2） Eth0连接测试 
Eth0 test for Wth0 connection 
连接网线：将评估板“eth0”对应的接口与计算机有线网卡的接口用网线相连接 
lan line connection:connect interface corresponding to “eth0”on evaluation board with interface of cable network interface card on computer through lan line 
设置评估板IP： 
set IP for evaluation board 
＃ ifconfig eth0 192.168.18.36 ＃ configure the eth0 
执行测试命令： 
execute test command 
＃ ping 192.168.18.18 -c 2 -w 4 ＃ send ICMP to HOST 
观察测试结果：系统会输出类似如下信息： 
view test result,you can see information outputed by system like below 
--- 192.168.18.18 ping statistics --- 
2packets transmitted, 2 packets received, 0% packet loss 
测试结果：“0% packet loss”表示测试通过

usb 2-1: USB disconnect, device number 12 
4）拔下USB转接线，系统会输出类似如下信息： 
take out USB switch wiring,system will output information like below. 
ci_hdrc ci_hdrc.0: remove, state 4 
usb usb2: USB disconnect, device number 1 
ci_hdrc ci_hdrc.0: USB bus 2 deregistered 
 
USB HOST测试(USB HOST test) 
　　MY-IMX6-EK140 的USB HOST是插座形式，如要测试HOST功能，需要把自备USB头，并且将插座上的USB HOST信号线连接到USB头，此操作请找自己的硬件工程师请求支持。 
　　MY-IMX6-EK140 USB HOST is socket type，if need to test the function of HOST，need to connect signal line of USB HOST to the USB head self-prepared，?the operation need an assistance from hardware engineer. 
　　另外，请硬件工程师知晓，由于CPU的USB_VBUS供电能力不足，需要将“5V_core”与USB_VBUS相连。 
　　Moreover，please let engineer know that power supply capability of CPU的USB_VBUS is not enough，so need to connect“5V_core”with USB_VBUS

测试说明(test instruction) 
MY-IMX6-EK140的TF卡接口不支持热插拔。 
MY-IMX6-EK140的TF card interface doesn't support hot plug 
 
测试方法(test method) 
1）为MY-IMX6-EK140断电。 
power off MY-IMX6-EK140 
2）将TF卡安装好板子的TF卡座上，并确认安装好。 
install TF card in TF card holder,and confirm the installation ok 
3）为MY-IMX6-EK140上电，待系统启动完成后进入系统。 
power on MY-IMX6-EK140,enter the system after booting is finished 
5）检查TF卡： 
check TF card 
＃ dmesg | grep "mmc0" 
TF卡正常则可以看到类似如下信息： 
if IF card is normal, then you can see information like below. 
mmc0: host does not support reading read-only switch. assuming write-enable. 
mmc0: new high speed SD card at address 0002

测试说明(test instruction) 
标准GPIO的测试以GPIO132为例，其它GPIO测试可参照GPIO132的测试方法。 
take GPIO132 as an example of standard GPIO test,other GPIO tests refer to the test method of GPIO132 
 
测试方法(test method) 
1）设置需要测试的GPIO的IO序号 
set IO order number of GPIO which need to be tested 
＃ OUT_IO_NUMBER=132 
2）导出GPIO 
lead out GPIO 
＃ echo ${OUT_IO_NUMBER} > /sys/class/gpio/export 
3）设置GPIO方向 
set direction for GPIO 
＃ echo "out" > /sys/class/gpio/gpio${OUT_IO_NUMBER}/direction 
4）控制输出电平 
control output electrical level 
＃ echo 0 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value 
执行命令后即可用万用表检测到对应的引脚为低电平。 
leads detected by multimeter accordingly will be low electrical level after execution of command 
＃ echo 1 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value 
执行命令后即可用万用表检测到对应的引脚为高电平。
