Below used to work for me in order to turn the ACT LED off on a Zero. Not any longer. I'm at a loss to understand why.
There's a load of statements out there that say this works.
Code: Select all
echo 255 | sudo tee /sys/class/leds/led0/brightness
If I cat the file afterwards I still see a 0.
The LED turns off for a fraction of second and then back on again. It's like the kernel overrides what I've done.
It's not working on a Zero with Jessie. Also not working on a Zero with Stretch.
Any thoughts? I'm at a loss.
(please, no suggestions about using tape )
