   @no1wudi The rough plan is to enable the usage of Rust within NuttX similar to CXX. It starts with the application part and later other areas may use it too. Currently the the basic rules and extensions to compile and link a simple hello_rust application is done.
   
   Some thoughts on the next steps where added to https://github.com/apache/incubator-nuttx-apps/pull/1014
   
       /1/ hello_rust --> done
       /2/ add rust to CI set-up --> done
       /3/ add defconfig sim:rust --> done
       /4/ add first target support (RP2040) --> started
       /5/ add libc crate for Rust (potentially using bindgen) --> started
       /6/ add a more complex application using libc crate
       /7/ enable access to hardware via specific crates
       /8/ add an example using the hardware crate
       /9/ test program to validate Rust on NuttX
       /10/ more will come as the journey goes on
   
   Getting the support into listed/libc is not yet of the road list, but in the long-run, this makes sense. Do you have experience with it and can explain, what is needed to get something like "thumbv6m-nuttx-eabi"?
