xtensa-lx-rt

Minimal runtime/startup for Xtensa LX processors. This crate currently supports the following CPU's:

| Feature | Supported CPUs | | --------- | ----------------- | | esp32 | ESP32 (LX6) | | esp32s2 | ESP32-S2 (LX7) | | esp32s3 | ESP32-S3 (LX7) | | esp8266 | ESP8266 (LX106) |

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.

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