note: i had a bunch in problems in the setting up chapter, kept getting an error when installing cargo-embed error failed to download smallvec v1.9.0 . after googling the following command worked cargo install cargo-embed --locked. I don't know if this way of installing the cargo-embed crate is the right way.
