Hi, just want to share a little tip:
How to turn the systemLED ("LED") to *ON* when the board is booting (loading the system).
![[Image: DSC_0045-photo-led.jpg]](http://www13.plala.or.jp/pskitty/img/pa64sysled/DSC_0045-photo-led.jpg)
My 1GB Pine64 Board sometimes start booting process and sometimes don't... so I have to way and "see" activities on the screen or LAN interface...
So, I decided to put an LED on the systemLED holes (label "LED"), and switch it to ON when booting...

When using without a monitor (remote) this LED is very helpful...
These 3 lines of script turn the LED to "ON":
Code: echo "359" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio359/direction
echo "0" > /sys/class/gpio/gpio359/value
Full instructions on the link below:
