Rockpro64 CPU fan

[Luke]

Try `rock64_diagnostic.sh -m` to display current status of the system.

I will tune the fan controls later to give more fine control. It is all about the duty cycle and period of square wave. We might be looking at 50-200Hz instead of last released 1kHz, and previously 100kHz.

The command on its own when entered into terminal results in "command not found". It seems like a bash file, but when I searched for it: no results. If it is a bash file, where is it located so I can test it?

Code:

/usr/local/sbin

As of today, if you want to try out the fan then you'll need to update the kernel:

Code:

https://github.com/ayufan-rock64/linux-kernel/releases/tag/4.4.132-1077-rockchip-ayufan

Currently the fan works in an on/off mode (at least for me):

Code:

nano /sys/class/hwmon/hwmon0/pwm1

The range should be from 0 - 255, but for now ... for me ... 0, 1 and 2 are 'off' while 3 and up is 'on'.

I connected a standard 12 V computer case fan. Around 80 the fan starts spinning slowly. But it vibrates until I set the value around 240.

Couple of things: I am still new to all of this too so I am with you! Have you successfully booted your machine and cannot get the fan to work or are you asking how to get everything set-up for the first time? If you need help getting it set-up the Noob page is where I started. 

If you just need help with the fan, then log into the terminal and type in the code that starts with "nano" in the reply above. It should pull up a screen with a zero in the top left and some commands at the bottom. Change that zero to a number between 0-255 then hit Ctrl+X and type Y or yes when it asks if you want to over write. That should turn your fan on. I am having an issue though with these settings not being enforced when I reboot. So I have to go back in to turn the fan back on.

I connected a fan but I'm not sure it's getting enough power. It's a 120mm fan. Am I risking damage with this size fan?

Hello gonde,
There are different possibilities for that..
On kernel 4.4.138-1097-rockchip-ayufan-gb5128c0a1684( its what I have ), I use ats
But with newer kernels I don't know if it work ok( I haven tested yet )

Then you would  be able to control Fan, with that Tutorial..

Anyone been able to get the fan to stay on with the mainline kernels? I haven't been able to get the 4.x ayufan kernels to support the PCIe card, so had to use the mainline kernel.

echo 255 > /sys/class/hwmon/hwmon0/pwm1

This turns the fan on, but it'll eventually go to 102, then turn itself to zero.

Also, I tried ats, but it's not for me (sorry). I just want to keep the fan full blast. It's in a closet so it doesn't matter. Also, ats auto shuts your system down when it gets too hot and there's no way to turn that off (the governor should throttle if it gets too hot, I hope?). Oh, and ats doesn't solve the issue anyway, since it does the same thing.
