    soerenderfor reacted to usual user in How to control FAN on Rockpro64?   
    ftdoverlay is a convenient way to apply an overlay staticly to a base dtb. You spare the DTC decompile - manually edit - DTC compile dance. Usually you write overlays with label refernces, but to be able to apply such an overlay, the base dtb has to be compiled with the @-option. This has significant impact on the size and distributions usually don't do this. When you write the overlay with full paths, it contains all the information to be applied to a base dtb that was not created with the @-option. The mainline ftdoverlay need the patch to be able to apply it.
     
    Edit the pwms property to any value you like as shown in the provided rk3399-rockpro64-tz.dts (50000 default changed to 10000).

    Did you buy the sata power cable from pine also? It splits the power into 2 sata cables and on both mount a splitter. Or you can like you say just split one cable to 4 with a sata splitter. I do power my rockpro64 with 4hdd in that way with a 12v 10a psu. It works like charm, no problem (but 8A is enough).

    @wolf7250 - Just so you know, if you plan to use that NAS case from pine. In that case there is only room for 2x 3.5" and 2x 2.5". But back to your question, i have found a universal PSU from 7.5volt to 22.5volt and 10amp, so i did just use that one. 

    Use 12V always to ROCKPRO64, and around (8A on the safe side) or so to power it all.

    Yes, "0" off and "255" full speed. You can change anything inbetween.
     
    I have 4 disk in the nas case, the 80mm noctua i did have installed before it was enough to cool it down, CPU temp around 40degress.  The orginal 80mm fan that "belongs" to the case is only around 10mm in thickness, and the noctua is 25mm. So to fit in the small space 90degree sata power cables is a very great idea. But you can fit normal sata power cables with some "violence" ;-)
     
     
    No, I like always on, so i did find a number to fit my demands. But many fan scripts is avaible, but you have to fit it the fan controller (FAN name)
     
    Just cut the cables and fit the plus and minus wire to the same cables at the fan. Very easy. Hope it was a little help, just ask again if there is something i can help with. Thanks.
    The reason i did fit a 92mm noctua in the case was to get it silent, nothing else.

    With new kernels the fan spins at "255" always, you can find the fan with this command 
    sudo find /sys -name pwm1 | grep hwmon and then change the output to your setup - But on the new kernels the fan point can jump, i am not sure of what reason.

    I have tested the Ziti... card for 1 week now, and runs very nice. So go for it, works right out of the box with new kernel also.

    @wolf7250 - That card from pine64 should be avoided in my opinion, i did only have trubles with it.  I have only cards with Marvell chipset, and i found out buy a simple card not a fancy raid card - less problems. I can later today find my different cards and name them for you.

    In my opinion it is a fine board, I run my ROCKPRO64 as a NAS. Runs 24/7 - wirh a sata card and 4 harddrivers in the nas case. OMV works fine, but there can be some probs with sata cards. 

    I run krenel 5.7.13 focal, no problems what so ever. And it runs very stable.

    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
