Hi, I bought a 2-pin piezo buzzer to use for alarm messages. It is connected to the P4 header on the board. When I execute the "beep" command in the console I only get short click noises. Are special kernel drivers necessary for a correct function?

Inspired by this topic https://forum.odroid.com/viewtopic.php?t=29069 I installed a shutdown script in /lib/systemd/system-shutdown: #!/bin/bash case "$1" in kexec) # Do not park disks when switching kernels. ;; *) for disk in /sys/block/sd* ; do echo 1 > /sys/class/block/${disk##*/}/device/delete done sleep 1 ;; esac this works for my needs. I don’t know if this problem is Helios64 specific, if not please move this topic to armbian common issues..

Hi, I’m using the Helios64 with Armbian 20.11 Buster ( 5.9.10-rockchip64) On every reboot the SMART counter for “Unexpected_Power_Loss (174)” / “POR_Recovery_Count (235)” incresses by one. I’ve seen this unexpected behaviour on Samsung, WD and Crusical SSDs … Rebooting the box with sync && echo 1 > /sys/block/sdX/device/delete && reboot turns the disk friendly off, but shouldn’t this be done in systemd/kernel?
