I get linker errors when I build for debug

Xtensa only provides a small code space for exceptions to fit inside, when building an unoptimized build the code size of a exception handler may exceed that size, causing a linker error. To fix this, you should always optimize this crate, even in debug builds. Adding the following to your projects Cargo.toml should do the trick.

[profile.dev.package.xtensa-lx-rt]
opt-level = 'z'
