13:35 <wangeng[m]> What's wrong for it?

13:55 <adamgreig[m]> it might be that you're missing the linker script

13:55 <adamgreig[m]> you should either have a `build.rs` with `println!("cargo:rustc-link-arg=-Tlink.x");`, or a `.cargo/config.toml` with...

13:56 <adamgreig[m]> or something to that effect

13:57 <wangeng[m]> There are build.rs and memory.x file in workspace directory.

14:14 <JamesMunns[m]> you still need to tell the linker to use link.x, as Adam said above.

14:15 <JamesMunns[m]> cortex-m-rt provides `link.x`, which includes your `memory.x`, but you need to tell the linker to use `link.x` (either in the build-rs or `.cargo/config.toml`, which I haven't seen in any of your screenshots.

14:19 <wangeng[m]> uh,,,,, I'll try it later, thank you very much!

16:02 <Noah[m]> What I find a bit unfortunate is that a missing linker script still compiles silently and is like "here take zero bytes binary"

16:05 <thejpster[m]> yeah, rust-lld seems to ship with a default configuration that just drops everything. That's not terribly helpful.
