Error code E0775

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

Erroneous code example:

#![allow(unused)] #![feature(cmse_nonsecure_entry)] fn main() { #[cmse_nonsecure_entry] pub extern "C" 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
