Disabling ethernet LEDs on aarch64 RPi 4

Postby Terin » Fri Mar 17, 2023 10:15 pm

Hey all,

I just upgraded my Raspberry Pi 4 installation to aarch64 from ARMv7. It's gone smoothly, except now I can't disable the ethernet LEDs on the device. It's in my room, so I like to have no lights flickering at night, and would prefer to do this on the OS's end rather than somehow using electrical tape/markers.

On the ARMv7 installation, I could disable everything with the following in /boot/config.txt:

$this->bbcode_second_pass_code('', '
# Power LED
dtparam=pwr_led_trigger=none
dtparam=pwr_led_activelow=off

# Activity LED
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off

# Ethernet Activity
dtparam=eth_led0=14

# Ethernet Link
dtparam=eth_led1=14
')

But none of those seem to take in aarch64. I can manually turn off the Pi-specific LEDs by modifying /sys/class/leds/ACT or PWR, but I can't find anything for the ethernet LEDs. Anyone know what I could put in /boot/config.txt for aarch64? Or even just a way to do it manually?

Are you using linux-aarch64 or linux-rpi on your 64-bit machine? Guessing you need the latter ...

Ah ha, didn't even realize there were the different kernel options! Swapping over to linux-rpi and rebooting gave me a perfectly lightless Pi. Thank you so much!
