Controlling LAN LEDs individually

[errazzor]

The script works like a charm on a Pi 3 !

i did the same what dom wrote above.

Absolutely perfect, THANKS VERY MUCH to all here ! This is a mandatory function for me, because the Pi3 is in my bedroom.

Turning off all LEDs should be a standard function, i really dont understand why this is not possible out-of-the-box!

Cheers!

i get this error when trying to make on rpi3

Code: Select all

gcc -lusb llctl.c -o llctl
llctl.c:10:17: fatal error: usb.h: No such file or directory
 #include <usb.h>
                 ^

Did you install libusb-dev?

er...... no.....

(works fine now)

Yep same here..

​There is an dtparam that can control led behaviour - see https://github.com/raspberrypi/firmware ... EADME#L96​

It was added March 21, so requires a kernel newer than that date.

Would this work for Pi 3 v1.2 ?

Because mine still keep blinking after I add

Code: Select all

dtparam=eth_led0=14
dtparam=eth_led1=14

to /boot/config.txt

I did a rpi-update to 4.14.39-v7+ May 5, not help.

This is currently a Pi 3B+-specific feature. The default LED modes weren't very useful so we had to change the LAN7800 driver anyway, and making the modes user-selectable was a simple extension.

[bensimmo]

Any plans to bring it to the older ones as I need it (just to make it easier) on B/B+ (v1) as they make good camera pi.
If not, could you add a note to the readme that it's 3B+ only (or7800).

I'm guessing this won't work on the Raspberry Pi 3 Model B+ due to the new gigabit ethernet chip? I tried to compile and run it (with sudo), and all I get are segmentation faults.

See the posts before yours for a different solution for 3B+

RPI 3 B+ disabling Network LEDs with dtparm worked fine but...

Is there an option a Raspberry 3 B+ for disabling the power and activity LED with dtparm?

Couldnt find a parameter for them....

Thanks

HI,
a bit late, but if you still did not found the answer:

Just add these lines before

Code: Select all

exit 0

line of the /etc/rc.local

Code: Select all

#Power LED off
echo none > /sys/class/leds/led1/trigger
echo 0 > /sys/class/leds/led1/brightness
#Activity LED off
echo none > /sys/class/leds/led0/trigger
echo 0 > /sys/class/leds/led0/brightness

This should disable the leds altogheter during the bootup.

Yep it works. I saw a new commit at github though dated February 2017 (https://github.com/dradermacher/lan951x-led-ctl) downloaded and compiled it but could not get it to work

Ditto

I did

Code: Select all

root@raspberrypi:~/git#  apt-get install libusb-dev
root@raspberrypi:~/git# make
gcc -lusb llctl.c -o llctl
strip llctl
root@raspberrypi:~/git# ./llctl f0 l0 d0
Segmentation fault

I downloaded the file from this post.

Code: Select all

Hello,

Did anyone test this on RPI 4 ? and if so can I please get step by step guide as I am not very good at Linux, I am running the new Raspbian OS, managed to get the ACT and PWR leds to be off but the ETH0 is quite strong leds and blinking

[no3rpi]

for rpi4 add this to boot config.txt

Code: Select all

# Turn OFF Network LED's
dtparam=eth_led0=14
dtparam=eth_led1=14

I'm also getting a segmentation fault when trying to run this on my Raspberry Pi 3 Model B Rev 1.2 running Arch. I see some others stating that here and only the reply "See the posts before yours for a different solution for 3B+", but there is no solution above that, maybe it was deleted. So has anyone figured out how to solve this?
(I've also tried the /boot/config.txt method at viewtopic.php?p=1445502&sid=f0624b63887 ... 6#p1445502 , it does nothing.)

Edit: This tool works fine for me: http://lrusak.libreelec.tv/public/lan951x-led-ctl
