Hello,

I was wondering if it is possible to disable both LEDs on this board or, at least, the green (stat) one. Also I was trying to remove wifi completely and I can do:

iwconfig wlan0 txpower off
ifconfig wlan0 down
systemctl disable wpa_supplicant

But not sure if it's possible to remove the driver from the OS and what other unnecessary software I can remove.

 

Thank you in advance.

I would like to know that as well.. and bluetooth!

for the LEDs you can try the following:

ls -l /sys/class/leds

(here as example from a NanoPi Neo2):

lrwxrwxrwx 1 root root 0 Feb 20 21:50 nanopi:green:status -> ../../devices/platform/leds/leds/nanopi:green:status
lrwxrwxrwx 1 root root 0 Feb 20 21:50 nanopi:red:pwr -> ../../devices/platform/leds/leds/nanopi:red:pwr

 

then echo none to the trigger of the led-name: 

 

echo 'none' > /sys/class/leds/[name_of_the_led]/trigger

 

so it should look like this:

 

echo 'none' > /sys/class/leds/nanopi:green:status/trigger

 

You only have to check the led-names of your board and add the commands in /etc/rc.local before "exit 0"
