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。

J13:11

测试说明(test specification)

1）采用SPI自发送（输出）自接收（输入）的方式。
adopt way of SPI self-sending（output）self-receiving（input)。
注意：测试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：the test 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。

2）与SPI测试程序匹配的SPI接口是SPI2，所以我们的SPI测试是测试SPI2。
SPI port which is matched up with SPI test program is SPI2，e.g.SPI test is SPI2 test。

测试方法(test method)

1）准备测试
prepare test
短接SPI2的MISO和MOSI管脚。
short connect MISO pin and MOSI pin of SPI2。
2）执行测试
execute test
＃ ~/my-demo/linux-3.14.52/spidev_test.out -D /dev/spidev1.0
3）测试结果
test result
如果SPI正常，在终端上会看到如下字符：
if SPI is normal,you can see following charaters on terminal：
FF FF FF FF FF FF
40 00 00 00 00 95
