How do I get this to work....

I tried the Raspberry 64 script and can get the driver to load, but it crashes within a few minutes.

The file is where it says it should be...but I get the above error message.

Thanks!

If I use pwmFanControl64, I get this...but the fan doesn't seem to be working

My temp is sitting at 141 Degrees. Dietpi is complaining it is way too hot. The PI is doing very little so the temp should be lower.

I've tried changing the fan control to 100% all the time, but it doesn't do anything.

pwmFanControl64 stopped working...it hangs on starting. Is there any support here?

if your repo is up to date now, you can look in the Ubuntu64 install script, and manually run the gcc command that generates and installs /usr/bin/pwmFanControl64.

There have been 2x PR's that fix bugs in pwmControlFan.c since this was posted
