I can see Lup is already on the GH thread this is good news :-) I would suggest to limit Rust for the Application part and see how it works.. just as we have Basic, Python, Lua, Zig, etc working on top of existing untouched POSIX RTOS architecture.. then create several demos using display sound etc to show others how to port Rust applications to NuttX :-) Below are my concerns in depth for our internal discussion.. maybe you have similar thoughts.. and you can safely ignore that part :-) There are some Rust based OS already out there. Look how many! Some of them does not even plan to support security mitigations, sensor devices, BLE, WIFI, etc. Why? How does setup of those Rust OS SDK compares to current NuttX environment setup and build times?? https://github.com/flosse/rust-os-comparison Instead of injecting unimaginable maintenance nightmare into existing minimalistic projects Rust fans can simply focus on building new alternative solutions and prove these are better in practice - by results - they need to build commercial products on top of their OS, ship it, maintain it, take full responsibility for the results, after some years we will see how it works. I will be first to congratulate and buy a good Open-Source based Rust product. But right now that push for injecting Rust into all possible OS/RTOS seems really suspicious not to say viral and dangerous!! Lup can do magic with NuttX like running applications written in other programming languages and convert NuttX code to different programming languages in order to run on new platforms and environments. All is done in non-invasive way, respecting current architecture and backward compatibility, adding new functionality that is optional and diamond clean in maintenance. This is the only way to go! :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
