Running Embassy on Raspberry Pi2, 3, 4, 5 as bare metal application?
I've been trying to google to look for any blogs or existing resources on this, but coming up blank. While I understand there are projects using the RP* microcontrollers, has anyone tried running Embassy as a bare metal RTOS on a full Raspberry Pi SoC?
Assuming a generally working HAL could be located or built, what would it take to get Embassy to run on a CPU rather than a microcontroller?
For example, in C++, there's the Circle project that enables writing software for Pi running on bare metal. I think it would be awesome to have something similar in Rust to open up a whole world of safe edge-computing possibilities.
I haven't dug deeply enough to see if this is using syscalls to a kernel under the hood, but initially seems interesting in terms of a starting point for a HAL in Rust, with coverage of most Pi's. https://docs.rs/rppal/latest/rppal/index.html
