# Error code E0775

#### Note: this error code is no longer emitted by the compiler.

`#[cmse_nonsecure_entry]` is only valid for targets with the TrustZone-M extension.

Erroneous code example:

    #![feature(cmse_nonsecure_entry)]

    pub extern "cmse-nonsecure-entry" fn entry_function() {}

To fix this error, compile your code for a Rust target that supports the TrustZone-M extension. The current possible targets are:

- `thumbv8m.main-none-eabi`
- `thumbv8m.main-none-eabihf`
- `thumbv8m.base-none-eabi`
