When you do

cargo clippy --target thumbv6m-none-eabi

It says:

error[E0599]: no method named `compare_exchange` found for struct `core::sync::atomic::AtomicU8` in the current scope
 --> /home/fluffy/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/spin-0.9.8/src/once.rs:114:18

113 | | .0
114 | | .compare_exchange(old as u8, new as u8, success, failure)

Issue seems to be on this line.

Have you taken note of the information in the README about support for platforms that don't have atomic intrinsics? I think that should solve this problem.
