how to indicate a rootfs on FastModel

I'm trying to run linux arm64 kernel on fast model. I followed the page

After all steps, I had got linux-system-foundation.axf and linux-system.axf.

then I use command as below:

model_shell   linux-system-foundation.axf

The console complained that I didn't indicate a right root path. I had download the pre-built root filesystems

from Linaro Releases, But I don't know how to use it.

Cound anyone help me? thank you!
