[rpi3b+] /sys/class/leds/{ACT,PWR}/brightness: No such file

Postby arch64 » Mon Jan 17, 2022 4:12 pm

I cannot control the ACT and PWR leds after upgrading to linux-aarch64-5.15.13-1 from linux-aarch64-5.15.5-1 on the RPI3b+.

Code: Select all
echo 0 > /sys/class/leds/ACT/brightness
-bash: /sys/class/leds/ACT/brightness: No such file or directory
echo 0 > /sys/class/leds/PWR/brightness
-bash: /sys/class/leds/PWR/brightness: No such file or directory

Does it work with raspberrypi-bootloader from [alarm] not from my repo?

https://github.com/raspberrypi/firmware/tree/next/boot has not been updated in a few weeks. Perhaps they didn't push a needed commit/fix to it???

Upgraded linux-aarch64 (5.15.13-1 -> 5.16.1-1) and raspberrypi-bootloader (20220113-1 -> 20220117-2) and everything works. Thank you!
