Hi all

I’m trying to disable the leds on a beaglebone black
When issuing this (with and without sudo)

echo none > /sys/class/leds/beaglebone:green:usr0/trigger

I get Permission denied

/sys/class/leds/beaglebone:green:usr0/trigger: Permission denied

uname -a
Linux beaglebone 4.14.108-ti-r113 #1 SMP PREEMPT Wed Jul 31 00:01:10 UTC 2019 armv7l GNU/Linux

The image is
bone-debian-9.9-iot-armhf-2019-08-03-4gb.img

Any help would be appreciated,
