After installing Arch Linux ARM on Raspberry Pi 3 model B, everything is working as expected but the green LED that indicates the SD card read write activity. The LED just blinks every second for 0.1 seconds and continues.
After installation, I did change the kernel printk otherwise it would show thousands of messages in any tty which is bad while installation. The
/etc/sysctl.d/20-quiet-printk.conf goes as follows:
kernel.printk = 7 4 1 7
cat /sys/class/leds/led0/trigger produces the following output:
none rfkill-any rfkill-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 timer oneshot heartbeat backlight gpio cpu cpu0 cpu1 cpu2 cpu3 activity default-on transient flash torch input panic netdev mmc1 [mmc0] rfkill0
How can I fix the LED blinking issue?
