Penta hat top, rock pi 4c and Ubuntu 20. No fan or oled

Recently purchased the rock pi 4c Penta hat combo pack. Got everything set up, but an unable to make the Penta top fan and oled screen to do anything. Fan or display never turn on. Using the latest Ubuntu server release.

Read for hours about how to make it work with no success.

Would like to get this functioning properly. Will be starting from scratch tomorrow. Any suggestions would be greatly appreciated.

Thank you.
