take out USB device,system will output information like below.
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

| MY-IMX6-EK140 | SNVS_TAMPER1 | gpio129 | SNVS_TAMPER1 | P21:16 |
测试说明(test instruction)
标准GPIO的测试以GPIO129为例，其它GPIO测试可参照GPIO129的测试方法。
take GPIO129 as an example of standard GPIO test,other GPIO tests refer to the test method of GPIO129
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=129
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。
leads detected by multimeter accordingly will be high electrical level after execution of command
