Top Hat Fan not working

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?

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

I don’t have any custom kernels or anything, it’s just a standard Raspbian

Thank you for your information. I will fix it tomorrow.

@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.

That worked for me, thanks @setq

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

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.
