    soerenderfor got a reaction from Mathias in Rockpro64 no hdd sleep over sata   
    sudo nano /etc/hdparm.conf
    #Disk1 /dev/disk/by-id/ata-YOURDISK { # mult_sect_io = 16 # write_cache = off # dma = on spindown_time = 240 } #Disk2 /dev/disk/by-id/ata-YOURDISK { # mult_sect_io = 16 # write_cache = off # dma = on spindown_time = 240 } 240 = 20mins - It works at my setup, i did't try lower spindown time.
     
    Some drives can bee spun down with hd-idle. change HD_IDLE_OPTS value, then start and activate hd-idle.service. let me know if it works. Thanks.

    More or less. The blue LED can say a lot, especially if the person cannot connect the console.
    This was useful not so long ago in the 5.x kernel where after upgrading from 4.14 simply Odroid HC does not boot and the diode just lights up all the time indicating that the sbc is hanging. For example, if the sd card were damaged and the boot partition is missing, the LED would not light up at all, the same effect as without an sd card.
    For novice users it is always best to stick to the standards because later unnecessary problems are created especially with headless sbc and no uart.

    That depends ... You can have such bash script too started /etc/rc.local :
    #!/bin/bash echo none >/sys/class/leds/blue\:heartbeat/trigger while true; do echo 0 > /sys/class/leds/blue\:heartbeat/brightness sleep 0.25 echo 255 > /sys/class/leds/blue\:heartbeat/brightness sleep 0.25 done Then, it will toogle/flash and will stop if kernel is frozen ...

    ODROID XU4, HC2, HC1, C2 and N2 does have the same blinking when turned ON. But you can easyli change the LED behavior with different commands put one of these commands in /etc/rc.local 
     
    Blue light off:
    echo none > /sys/class/leds/blue\:heartbeat/trigger
     
    Orignal state of light, it is called heartbeat.
    echo heartbeat > /sys/class/leds/blue\:heartbeat/trigger
     
    Constant on:
    echo deafult-on > /sys/class/leds/blue\:heartbeat/trigger
     
    On SD card access:
    echo sd >/sys/class/leds/blue\:heartbeat/trigger
     
    There is alot of different blue light settings. You can change blue light behavior to track your emmc and cpu load etc.
    cat /sys/class/leds/blue\:heartbeat/trigger

    Hi Igor.
     
    I do not have the rights to accept the offer as moderator.  
    But i would like to help, i can't maintain a Kernel or develop..  But sure i want to help in the forum to move wrong posting and edite here and there.  It should be nice place to seek information, also for beginners. 
    Nobody want to seek information a place where you get the feeling of being arduous.
     
    I have 20 years self-taugght computing/hardware skills.
    If i could help in some way just let me know.

    Best Regards.
