[Solved] Enable heartbeat LED on Arch

[Milliways]

I normally use heartbeat on my Pi, set with:-

Code: Select all

dtparam=act_led_trigger=heartbeat

This works with my other distributions, but when I tried this with latest Arch with kernel 4.4.44-1-ARCH on my Pi3, but it does not work; the LED remains off.

Code: Select all

cat /sys/class/leds/led0/trigger 
none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock usb-gadget usb-host mmc0 mmc1 timer oneshot [heartbeat] backlight gpio cpu0 cpu1 cpu2 cpu3 default-on transient flash torch input rfkill0 

seems to show that is has been set.

I thought the code to run this would be in the kernel. Is anything else needed?

After receiving no suggestions, I decided to try on a Pi2; the heartbeat worked normally, so I concluded it was a problem with the Pi3.

I updated the software to 4.4.45-1-ARCH and lo and behold it now works.
