To enable any of this modes you just have to change a parameter in the directory of the led you want to control. You can see all the possibilities using the instruction 'cat':<br>
<pre>$ cat /sys/class/leds/igep\:red\:led0/trigger
[none] mmc0 mmc1 timer heartbeat default-on
<pre>
$ echo 1 > /sys/class/leds/base\:blue\:led0/brightness$ echo 1 > /sys/class/leds/base\:red\:led0/brightness$ echo 0 > /sys/class/leds/base\:blue\:led0/brightness$ echo 0 > /sys/class/leds/base\:red\:led0/brightness
</pre>
<pre>cat /sys/devices/soc0/soc.0/2100000.aips-bus/21a8000.i2c/i2c-2/2-0050/eeprom</pre>
