Whoy whoud you want to do that? A ramdisk of that size is the worst
choice of a root file system you can make. Please read the manual!

What exactly are your environment settings (and why did you set
these like that) ?

That doesn't seem is if you actually needed 32 MB for the ramdisk?

Are you sure of this?

Is this really supported in your kernel port, and in your device tree?

How could we do that?

We don't know your hardware, we don't know your kernel port, we don't
know your kernel configuration, we don't know your device tree, we
don't know your root file system or which device nodes it contains,
we don't know anything about your system.

Sorry - based on zero input you cannot expect much useful output.

Best regards,
