板载status LED默认都是心跳灯状态,通过下面的命令可以查看相关的设置:
$ cat /sys/class/leds/status_led/trigger none rc-feedback rfkill-any kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalockk kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrll ock kbd-ctrlllock kbd-ctrlrlock usbport usb-gadget usb-host mmc1 mmc2 mmc0 timerr oneshot disk-activity ide-disk mtd nand-disk [heartbeat] backlight gpio cpu cpuu 0 cpu1 cpu2 cpu3 default-on transient flash torch panic netdev rfkill0 stmmac-0:: 00:1Gbps stmmac-0:00:100Mbps stmmac-0:00:10Mbps
[heartbeat]表示该 LED 的默认触发方式为心跳状态,通过改变trigger节点的值就可以改变LED的触发方式。
举例执行下面的命令可以让LED 保持常亮:
echo default-on > /sys/class/leds/status_led/trigger
