Build Rust applictions with cargo is the most commn way, and it's more easy to cooporate with Rust ecosystem. This example shows how to use cargo to build a simple hello world application. And please notice that you need to install nighly version of rustc to support this feature, any version after rust-lang/rust#127755 is merged, can use NuttX as cargo target directly. Build ----- To build hello_rust_cargo application, you can use any target that based on RISCV32IMAC, for example: ``` cmake -B build -DBOARD_CONFIG=rv-virt:nsh -GNinja . ``` And disable ARCH_FPU in menuconfig, since the hard coded target triple in this demo is `riscv32imac`.

should we generalize the common to a function for all possible arch?
