测试方法(test method)
1)GPIO输出测试
GPIO output test
  • 设置需要测试的GPIO的IO序号
set IO order number for GPIO of which need to be tested
# OUT_IO_NUMBER=85
  • 导出GPIO
lead out GPIO
# echo ${OUT_IO_NUMBER} > /sys/class/gpio/export
  • 设置GPIO方向
set GPIO direction
# echo out > /sys/class/gpio/gpio${OUT_IO_NUMBER}/direction
  • 控制输出电平
control outputed electrical level
# echo 0 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value
# echo 1 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value

2)GPIO输入测试
GPIO input test
  • 设置需要测试的GPIO的IO序号
set IO order number for GPIO of which need to be tested
# IN_IO_NUMBER=86
  • 导出GPIO
lead out GPIO
# echo ${IN_IO_NUMBER} > /sys/class/gpio/export
  • 设置GPIO方向
set GPIO方向
# echo in > /sys/class/gpio/gpio${IN_IO_NUMBER}/direction
  • 查看输入电平
check inputed electrical level
cat /sys/class/gpio/gpio${IN_IO_NUMBER} /value

3)验证输入输出
verify input&output
注意:这一步需要短接评估板的管脚,如果不确定自己能正确短接的请找硬件工程师支持,否则可能会损坏评估板。
note:this step need a short connection of evaluation board pins,if you are not sure of how to conduct this kind of connection,please ask hardware engineer for a support,otherwise it may cause a damage of evaluation board。
将前面配置的输出IO对应的管脚与配置的输入IO对应的管脚连接。即:在MY-IMX6-EK200上连接J4:10 - J4:12,在MY-IMX6-EK314上连接U14:29 - U14:30。
connect outputed IO pins configured above with inputed IO pins configured above correspondingly.。e.g:connect J4:10 - J4:12 on MY-IMX6-EK200,and connect U14:29 - U14:30 on MY-IMX6-EK314。
  • 查看输入管脚上的电平
check eletrical level of inputed pins
# cat /sys/class/gpio/gpio${IN_IO_NUMBER}/value
  • 更改输出管脚的输出电平
modify electrical level of outputed pins
# echo 1 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value
  • 查看输入管脚上的电平
check electrical level of inputed pins
# cat /sys/class/gpio/gpio${IN_IO_NUMBER}/value

GPIO-LED(Heartbeat)测试(GPIO-LED(Heartbeat)test)
系统启动完成后,用示波器检测heartbeat对应的接口,可看到如下类似信号:
after system booting is completed,check interface corresponding with heartbeat with oscilloscope,then you can see message like below:

提示:heartbeat是与CPU心跳关联的,如果在此GPIO上接上LED,即可通过观察LED来判断CPU是否工作。
tips:heartbeat is related to CPU heartbeat,if connect a LED wiht this GPIO,then we can adjudge whether CPU is working or not by LED。

GPIO-LED(Timer)测试(GPIO-LED(Timer)test)
系统启动完成后,用示波器检测timer对应的接口,可看到如下类似信号:
after system booting is completed,check interface corresponding with timer with oscilloscope,then you can see message like below:

通过delay_off、delay_on来控制高低电平持续的时间。
control high&low electrical time by delay_off、delay_on。
# echo 500 > /sys/class/leds/led-timer/delay_off
# echo 1000 > /sys/class/leds/led-timer/delay_on
再用示波器检测的时候,会看到波形发生的变化。
re-check with oscilloscope,you can see the change of wave shape。

GPIO-LED(Default ON)测试(GPIO-LED(Default ON)test)
Default-on可以通过brightness控制。
Default-on can be controled by brightness。
Default-on的实现是初始触发状态为on,即初始触发后为高电平。
Default-on is set to be on for original trigger,e.g it is high electrical level after original trigger。
# echo 1 > /sys/class/leds/Default/brightness
往brightness写0即可检测到低电平。
write 0 to brightness to detect low electrical level 。
# echo 0 > /sys/class/leds/Default/brightness

GPIO-LED(GPIO)测试(GPIO-LED(GPIO)test)
GPIO的测试可以使用跟default-on类似的方法:
GPIO test can be in similar way as test of default-on:
# echo 1 > /sys/class/leds/gpio1_12/brightness
使用万用表测试LED:gpio对应的引脚,可以看到该引脚是高电平。
test pin corresponding with LED:gpio with multi-meter,you can see the pin is high electrical level。
# echo 0 > /sys/class/leds/gpio1_12/brightness
使用万用表测试LED:gpio对应的引脚,可以看到该引脚是低电平。
test pin corresponding with LED:gpio with multi-meter,you can see the pin is low electrical level。

测试方法(test method)
1)执行测试程序
execute test program
在终端下键入命令执行测试,示例如下:
enter command to execute on terminal,example as below:

2)选择测试设备
select test device
Select the device event number [0-2]: 2
输入“gpio-keys”对应的序号,这里是2
enter order number corrsponding with“gpio-keys”,here it is 2

3)进行交互测试
proceed with interactive test
在终端会看到“Testing ... (interrupt to exit)”,这时我们按下或松开SW4、SW3、SW2。会看到如下类似信息:
on terminal you can“Testing ... (interrupt to exit)”,this time press or release SW4、SW3、SW2。message like below will come out:
Event: time 1452590477.115958, type 1 (EV_KEY), code 116 (KEY_POWER), value 0
Event: time 1452590477.115958, -------------- SYN_REPORT ------------
Event: time 1452590478.415953, type 1 (EV_KEY), code 115 (KEY_VOLUMEUP), value 1
其中“value 1”信息是在按键被按下的时候被输出,“value 0”信息是在按键被松开的时候被输出。
message of“value 1”is outputed with press of key,message of“value 0”is outputed with release of key。

3)结束测试
end test
按计算机上的“Ctrl”+“C”可结束按键测试程序。
press “Ctrl”+“C”on computer to end the test program for keys。

串口测试(serial port test)
MY-IMX6-EK200共5个串口,其中1个调试串口,4个用户串口。
MY-IMX6-EK200 has total 5 serial ports,one is debug seiral port,the other 4 are user serial ports。
