＃ OUT_IO_NUMBER=85

Lead out GPIO

＃ echo ${OUT_IO_NUMBER} > /sys/class/gpio/export

Set GPIO direction

＃ echo out > /sys/class/gpio/gpio${OUT_IO_NUMBER}/direction

Control outputed electrical level

＃ echo 0 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value

Set IO order number for GPIO of which need to be tested.

＃ IN_IO_NUMBER=86

Lead out GPIO

＃ echo ${IN_IO_NUMBER} > /sys/class/gpio/export

Set the GPIO direction

＃ echo in > /sys/class/gpio/gpio${IN_IO_NUMBER}/direction

查Check inputed electrical level

cat /sys/class/gpio/gpio${IN_IO_NUMBER} /value

3）Vrify input&output
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.

＃ echo 1000 > /sys/class/leds/led-timer/delay_on
Re-check with oscilloscope,you can see the change of wave shape.

GPIO-LED（Default ON）test

Default-on can be controled by brightness.
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
Write 0 to brightness to detect low electrical level .
＃ echo 0 > /sys/class/leds/Default/brightness

GPIO-LED（GPIO）test

GPIO test can be in similar way as test of default-on：
＃ echo 1 > /sys/class/leds/gpio1_12/brightness
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
