Top Hat Fan not working

Mike_J · July 8, 2020, 6:09pm

After updating the PI software and packages, upgrading the firmware and reinstalling the script the top hat fan will not spin. Several reboots and complete power shutdown/unplugged the fan will not activate at any temp. I verified the fan does have power and is not defective. My thought is that in the updating process the code to activate the fan is stopped working. Thoughts/ideas? Appreciate the help.

What about uname -a?

Please downgrade your kernel to stable.

Results of uname -a
Linux PiNAS 4.19.118-v7l+ #1311 SMP Mon Apr 27 14:26:42 BST 2020 armv7l GNU/Linux

To be clear the kernel was not updated when I performed the standard sudo apt update && sudo apt -y full-upgrade

What kernel do you suggest I downgrade to?

setq · July 9, 2020, 4:13pm

I thought you have done an rpi-update.

Please tell me the result of sudo systemctl status pigpiod.service

Hi,

I’m experiencing the same problem here, I just updated the rockpi drivers and now temperature a rocketing to 70 celsius on idle. Also, my fans are reversed and I didn’t reach above 55 after doing it.

I’m seeing the same Python errors while checking the Rockpi service

@fmo @Mike_J

Hello, I uploaded a new version and I think the bug should be fixed.
Please reinstall it and let me know the result.

fmo · July 13, 2020, 8:27am

That worked for me, thanks @setq

Mike_J · July 13, 2020, 3:10pm

Fix and working. Curious to know what the bug was. - Thanks for your help.

setq · July 14, 2020, 2:22am

The pigpio daemon listening ip6-localhost but the pigpio client uses localhost by default.

The bug may be caused by the different content of /etc/hosts.

Hi,
I’m running Ubuntu 20.04, and the top fan was working fine until today when I updated some packages.

Start-Date: 2020-08-05 11:12:39
Commandline: apt upgrade
Requested-By: mediadmin (1001)
Upgrade: apport:arm64 (2.20.11-0ubuntu27.4, 2.20.11-0ubuntu27.6), python3-apport:arm64 (2.20.11-0ubuntu27.4, 2.20.11-0ubuntu27.6), python3-problem-report:arm64 (2.20.11-0ubuntu27.4, 2.20.11-0ubuntu27.6)
End-Date: 2020-08-05 11:12:54

After that the fan no longer spins up.

I reinstalled the rockpi-sata drivers (now it shows 0.14) which rebuilt the pigpiod drivers and it’s working fine now.
