I love Tiny Core Linux for use cases where I need fast boot times or have few resources. Testing old PCs, Pi Zero and Pi Zero 2W are great use cases.
Thank you for that comment, I did not realize Pi Zero and Pi Zero 2W worked with TCL. I am brewing an application for that environment right now so this may just save the day and make my life a lot easier. Have you tried video support for the Pi specific cams under TCL?
I don't know about CSI cameras. My use case for TCL doesn't require a CSI camera. But it looks like others have made a CSI camera work:

I recommend asking on that forum. Folks are helpful.
