There are many possible reasons!

You're going to have to do some debugging to find out!

You haven't said what hardware you're using - first thing is to check that it is all correct, working, properly configured, and correctly connected.

I would suggest that you start with some simpler projects to gain familiarity with the product & the tools - getting a filesystem working is not really a "first project"!
