Thanks for reporting! For now, you can probably fix this by upgrading cortex-m in the Cargo.toml file to 0.6 instead of 0.5; but the underlying problem is a bug in the new 0.6.6 version of cortex-m which will need fixing.

@adamgreig suggested the following work-around. He said a "proper" fix should be coming maybe tonight:

$ git diff .

After that change I was able to successfully build:

I'll note we are also hitting this in the ATSAMD CI (ie: atsamd-rs/atsamd#391): https://github.com/atsamd-rs/atsamd/pull/391/checks?check_run_id=1765507423

This is a bug in cortex-m 0.6.6 which we will fix soon, but is there any particular reason you're still using 0.5?

322: Fix missing peripheral::itm export, prepare v0.6.7 r=jonas-schievink a=adamgreig

This fixes the issue where cortex-m 0.5.10 re-exports 0.6's peripheral::itm module; in principle it's possible other crates could have been using this module directly too (it is public) but in practice it doesn't contain anything useful (all the useful things are in the top-level itm module).

Should fix rust-embedded/discovery#287.

HI all,

The problem was fixed with cortex-m = "=0.6.7" in auxiliary/Cargo.toml .
It seems that there's still some other package using cortex-m v0.5.10. But the project works, it's ok now.
thank you very much.
