1 week ago I'd like to confirm a similar issue: I was trying to start with the ethernet_w5500_tcp_server demo, but when I used what I thought was the correct manifest, it failed to compile.
I went into the repo and deleted all path references, then deleted things until Cargo stopped complaining (in particular on things like how embassy-net == 0.4.0 does not have features multicast and raw, and embassy-rp == 0.2.0 doesn't have rp2040, but the manifest in the repo does successfully mention them.
It seems as though the repo contains some breaking changes which were not published to crates.io, but which were fixed in the examples, so the examples no longer work with the released versions.
After that was done, my manifest looked like:
[package]

Error Failed to run cargo build: exit code = Some(101).
If you copy/paste the code from the RP2040 USB logger example into a new project, it will not compile.
Here is the cargo manifest I used:
and the compile error:
I suspect that this is due to some build error in the tagged version. I tried pointing just the
embassy-usb-loggercrate to the upstream but got a compile error about two different versions of a trait (understandable).So I updated all of the embassy crates to point at the upstream and that seemed to work. It's a good enough work around for me to continue but figured you would like to know!
